Contract Review in Manufacturing: ISO 9001 and AS9100 Best Practices

Contract review is the process of confirming that every customer requirement is understood, documented, achievable, and accepted before a manufacturer commits to an order.

A customer Purchase Order may include much more than part numbers, quantities, prices, and delivery dates. It can also contain drawing revisions, quality clauses, certifications, special-process requirements, packaging instructions, traceability obligations, customer-specific terms, regulatory requirements, export restrictions, and documentation deliverables.

When those requirements are not identified before order acceptance, problems often appear later as material shortages, unavailable capacity, incorrect revisions, unapproved suppliers, missing certifications, late deliveries, quality escapes, rework, customer disputes, or unprofitable work.

The purpose of contract review is to prevent the company from accepting an order until every applicable requirement has been reviewed and the organization has determined that it can fulfill the commitment.

What Is Contract Review in Manufacturing?

Contract review is a controlled evaluation of customer requirements before a quotation, Purchase Order, contract, Sales Order, or amendment is accepted.

The review determines whether the organization:

Understands the customer’s stated requirements.
Has identified requirements that may not be clearly stated.
Can manufacture or provide the requested product or service.
Has the necessary labor, equipment, tooling, materials, suppliers, and capacity.
Can meet the required delivery schedule.
Can satisfy quality, technical, regulatory, and contractual requirements.
Has resolved differences between the quotation and the customer Purchase Order.
Has identified and addressed unacceptable commercial or legal terms.
Can maintain required records, traceability, certifications, and documentation.
Has received the required approvals before accepting the order.

Contract review may also be called customer order review, Purchase Order review, Sales Order review, order-entry review, quotation review, or requirements review.

Why Contract Review Matters

Accepting a customer order creates operational, commercial, and often legal obligations. Once the order is accepted, the manufacturer is expected to provide the specified product or service according to the agreed requirements.

Protects Product Quality

Contract review identifies drawings, revisions, specifications, quality clauses, inspection requirements, and required certifications before production begins.

Protects Delivery Performance

The review confirms material availability, supplier lead times, production capacity, outside processing, and realistic completion dates.

Protects Profitability

Unplanned testing, documentation, inspection, packaging, freight, tooling, or compliance requirements can turn a profitable quotation into a loss.

Protects Compliance

Formal review helps demonstrate control of customer requirements under quality-management and regulatory systems.

Protects Customer Relationships

Questions and conflicts can be resolved before acceptance instead of becoming disputes after production starts.

Protects the Organization

Unacceptable terms, liabilities, warranties, penalties, intellectual-property clauses, and export restrictions can be identified before commitment.

Order Entry Is Not the Same as Contract Review

Entering the customer’s Purchase Order into the ERP system records the transaction. Contract review determines whether the organization should accept that transaction and under what conditions.

Contract Review for ISO 9001 and AS9100

ISO 9001 and AS9100 require organizations to determine and review customer and product requirements before committing to supply products or services.

The review generally addresses:

Requirements specified by the customer.
Delivery and post-delivery requirements.
Requirements not stated by the customer but necessary for the intended use when known.
Statutory and regulatory requirements.
Requirements established by the organization.
Differences between the current order and previous agreements.
The organization’s ability to meet all applicable requirements.

Quality-System Expectation	Contract Review Evidence
Determine Customer Requirements	Customer Purchase Order, specifications, drawings, quality clauses, and communication records.
Review Before Commitment	Completed review and approvals dated before order acceptance or release.
Resolve Differences	Documented clarification, revised quotation, amended Purchase Order, or customer authorization.
Confirm Capability	Engineering, quality, purchasing, production, material, and capacity approvals.
Control Requirement Changes	Contract-amendment review and updated affected documents.
Retain Documented Information	Review record, approval history, comments, attachments, actions, and customer correspondence.

Organizations should verify all clause references and required records against the current edition of the applicable standard, customer contract, regulatory requirements, and internal procedures.

Contract, Purchase Order, Quotation, and Sales Order Differences

Document	Purpose	Contract Review Role
Request for Quotation	Customer request for price, delivery, and commercial proposal.	Requirements should be reviewed before quotation to ensure the proposal is achievable.
Quotation	Supplier offer describing price, lead time, assumptions, scope, and commercial conditions.	Becomes the baseline for comparison with the customer’s Purchase Order.
Customer Purchase Order	Customer document requesting products or services under stated terms.	Must be compared with the quotation and reviewed before acceptance.
Contract	Agreement establishing legally binding obligations.	May include the Purchase Order, quotation, terms, specifications, amendments, and referenced documents.
Sales Order	Internal ERP record used to plan and fulfill the accepted customer order.	Should reflect the final approved requirements established through contract review.
Order Acknowledgment	Supplier confirmation of accepted quantities, prices, dates, and conditions.	Documents the organization’s acceptance or qualified acceptance.

The Sales Order should represent the approved customer commitment. It should not be released using incomplete, disputed, or unreviewed Purchase Order information.

When Should Contract Review Occur?

Contract review should occur whenever the organization is considering a new or changed commitment to a customer.

Business Event	Recommended Review
New Request for Quotation	Review technical, quality, commercial, capacity, and delivery requirements before quoting.
New Customer Purchase Order	Compare the order with the quotation and complete the required approval workflow.
Repeat Order	Confirm revision, quantity, dates, requirements, pricing, capacity, and supplier conditions remain valid.
Customer Revision Change	Perform focused engineering, quality, planning, and cost review.
Quantity Change	Reassess capacity, material, purchasing, pricing, tooling, and delivery.
Delivery-Date Change	Review schedule feasibility, material availability, and resource conflicts.
Contract Amendment	Review every changed requirement before accepting the amendment.
Long Gap Since Last Production	Reconfirm tooling, suppliers, material, personnel, equipment, specifications, and certifications.
Customer Terms Change	Review commercial, legal, quality, warranty, and liability implications.
New Facility or Process	Confirm customer approval, qualification, validation, and documentation requirements.

Recommended Manufacturing Contract Review Process

1. Receive and Register the Customer Order

Record the Purchase Order, customer, date received, requested acknowledgment date, quotation reference, applicable contacts, and all received attachments.

2. Confirm the Complete Contract Package

Verify that all referenced drawings, specifications, quality clauses, terms, schedules, models, statements of work, and attachments are available.

3. Compare the Purchase Order with the Quotation

Identify differences in:

Part numbers
Revisions
Quantities
Prices
Delivery dates
Freight terms
Payment terms
Quality requirements
Documentation
Packaging
Warranty
Commercial terms

4. Classify the Review

Determine whether the order is:

A new product
A repeat order with no significant changes
A revision change
A high-risk order
A customer amendment
A government or defense order
An export-controlled order
A first-article order
A prototype or development order
A service or repair order

5. Assign Cross-Functional Reviewers

Route the order to the departments responsible for evaluating its requirements.

6. Identify Risks, Gaps, and Action Items

Reviewers should record concerns, questions, missing information, required estimates, approvals, and actions.

7. Resolve Customer Clarifications

Do not rely on assumptions when requirements are incomplete or conflicting. Obtain written clarification, a revised Purchase Order, or documented customer authorization.

8. Complete Required Approvals

Each required function should approve, conditionally approve, or reject the order from its area of responsibility.

9. Accept, Amend, or Reject the Order

The organization may:

Accept the order as written.
Accept the order with documented exceptions.
Request an amended Purchase Order.
Issue a revised quotation.
Negotiate delivery, pricing, or technical requirements.
Reject the order.

10. Create the Controlled Sales Order

Enter the final approved requirements into the ERP system and connect the contract-review record.

11. Communicate Requirements to Operations

Ensure that purchasing, planning, production, inspection, shipping, and other affected functions receive the approved requirements.

12. Retain the Review Record

Preserve approvals, comments, attachments, customer clarifications, amendments, and acceptance evidence.

Who Should Participate in Contract Review?

The required reviewers depend on the product, service, customer, risk, and applicable requirements.

Department or Role	Primary Review Responsibility
Sales or Customer Service	Customer communication, quotation comparison, pricing, dates, terms, and order completeness.
Engineering	Drawings, revisions, specifications, tolerances, design authority, configuration, and technical feasibility.
Quality	Quality clauses, inspection, certifications, traceability, first article, audits, and customer-specific requirements.
Production	Manufacturing feasibility, processes, work centers, tooling, labor, setup, and production risk.
Production Planning	Capacity, schedule, routing, material availability, constraints, and delivery feasibility.
Purchasing	Supplier availability, approved sources, lead times, minimum quantities, cost, and outside processing.
Inventory or Materials	On-hand material, shelf life, lot restrictions, storage, handling, and customer-supplied material.
Inspection	Measurement capability, inspection time, gauges, test equipment, acceptance criteria, and reporting.
Special Process or NDT	Qualified personnel, equipment, procedures, approvals, and outsourced process sources.

Part Number, Drawing, and Revision Review

Incorrect drawing or revision control is one of the most expensive contract-review failures because the organization may manufacture the wrong configuration even when workmanship is otherwise acceptable.

Review Item	Question
Customer Part Number	Does it match the quotation, internal cross-reference, and requested product?
Internal Part Number	Is the correct internal Item Master record being used?
Drawing Number	Is the required drawing available and approved?
Drawing Revision	Does the Purchase Order revision match the received drawing?
Specification Revision	Are all referenced specifications available at the required revision?
Model or Digital Data	Does the model revision correspond with the drawing and contract?
Previous Production	Was the previous order produced to the same revision and requirements?
Change Impact	Does the revision affect material, tooling, routing, inspection, cost, or delivery?

Do Not Assume a Repeat Part Number Means a Repeat Order

The customer may retain the same part number while changing the drawing revision, quality clauses, delivery requirements, approved sources, packaging, testing, or documentation.

Learn more about controlled product structures in our Bill of Materials guide.

Capacity and Delivery-Date Review

A requested delivery date should not be accepted until the organization evaluates the complete manufacturing and supply-chain lead time.

Material Lead Time

Confirm availability, minimum quantity, supplier lead time, certifications, shelf life, and approved source.

Production Capacity

Review available machines, work centers, labor, shifts, setup time, and current workload.

Tooling and Fixtures

Confirm required tooling exists, remains usable, and can be available when needed.

Outside Processing

Evaluate approved suppliers, transportation, queue time, processing time, and certification requirements.

Inspection Capacity

Allow sufficient time for first article, receiving inspection, in-process inspection, final inspection, testing, and document review.

Contingency

Consider material delays, equipment downtime, supplier risk, rework, and customer approval time.

Material and Purchasing Review

Purchasing should confirm that required materials, components, services, and suppliers can support the order.

Purchasing Requirement	Review Consideration
Approved Supplier	Is the supplier approved for the required item, process, or customer?
Approved Manufacturer	Does the customer require a specific manufacturer or approved source?
Lead Time	Can the supplier deliver in time to support production?
Minimum Order Quantity	Will purchasing create excess material or affect quoted cost?
Material Availability	Is the required grade, specification, size, or form commercially available?
Certification	Can the supplier provide required material, process, and test certifications?
Shelf Life	Can material meet minimum remaining shelf-life requirements?
Lot Control	Are lot segregation and traceability requirements achievable?
Outside Processing	Is the process source customer-approved or otherwise qualified?
Cost	Do current supplier costs support the quoted price?
Risk	Is the item single-source, obsolete, allocation-controlled, or otherwise high risk?

Learn more in our Approved Vendor List guide.

Quality Clause Review

Customer quality clauses frequently contain requirements that affect purchasing, production, inspection, documentation, shipping, and record retention.

Quality Clause Category	Possible Requirement
Certification	Certificate of Conformance, material certificate, test report, or process certification.
Inspection	Receiving, in-process, final, source, government, or customer inspection.
First Article	Full or partial first-article inspection and approval.
Special Process	Approved process source, qualified personnel, validated procedure, or customer approval.
Traceability	Lot, heat, batch, serial, process, operator, equipment, or material history.
Nonconformance	Customer approval before use-as-is, repair, rework, or deviation.
Change Notification	Customer notification or approval before changing product, process, source, facility, or tooling.
Record Retention	Specified retention period and destruction requirements.
Right of Access	Customer, regulatory, or government access to facilities, records, and sub-tier suppliers.
Flowdown	Requirements that must be communicated to suppliers and outside processors.
Counterfeit Prevention	Authorized sources, traceability, inspection, and reporting controls.
Foreign Object Prevention	FOD prevention, inspection, housekeeping, and packaging controls.

Quality clauses should be converted into actionable ERP, routing, inspection, purchasing, documentation, and shipping requirements rather than stored only as a Purchase Order attachment.

First Article Inspection Review

First Article Inspection can add significant planning, inspection, documentation, and customer-approval time.

Contract review should determine:

Whether a first article is required.
Which first-article standard or customer format applies.
Whether a full or partial first article is required.
Whether the requirement applies to the first piece, first lot, or first production run.
Whether previous first-article approval remains valid.
Whether a lapse in production triggers a new first article.
Whether a revision or process change requires requalification.
Whether the customer must approve the report before shipment.
Whether special tooling or inspection programming is needed.
Whether ballooned drawings and characteristic accountability are required.
Whether material and process certificates must be included.
Whether the quoted price includes first-article labor and documentation.

First Article Approval Can Affect Delivery

If customer approval is required before production or shipment, the delivery schedule must include the customer’s review and response time.

Special Process and Outside Processing Review

Special processes may include heat treatment, plating, coating, welding, brazing, soldering, nondestructive testing, chemical processing, and other operations whose results cannot always be completely verified through later inspection.

Review Question	Why It Matters
Is the process required by the drawing or specification?	The routing and supplier requirements must reflect the exact process.
Is the internal process qualified?	Personnel, equipment, procedures, and records may require approval.
Is outside processing required?	Purchasing and scheduling must include supplier and transportation lead time.
Is the supplier approved by the customer?	Use of an unauthorized source may make the product nonconforming.
Are certifications required?	Required documents must be obtained, reviewed, retained, and shipped where applicable.
Are process parameters fixed?	Changes may require customer notification or approval.
Does the process affect final dimensions?	Machining allowance, inspection sequence, and rework risk must be considered.
Is destructive testing required?	Additional quantity, specimens, cost, and lead time may be needed.

Customer-Supplied Material, Tooling, and Property

Customer property may include raw material, components, tooling, fixtures, drawings, software, test equipment, intellectual property, packaging, and confidential information.

Contract review should establish:

What property the customer will provide.
When it will be delivered.
Who is responsible for incoming verification.
How property will be identified and segregated.
How it will be stored and protected.
Who bears the risk of damage or loss.
How usage and remaining quantity will be reported.
Whether scrap requires customer authorization.
Whether unused material must be returned.
How tooling maintenance and calibration will be controlled.
What records must be retained.
How lost, damaged, or unsuitable property will be reported.

Customer-supplied material does not eliminate receiving, identification, traceability, storage, or condition-control responsibilities.

Export, Regulatory, and Government Contract Review

Government, defense, aerospace, medical, and export-controlled orders may require additional review by qualified personnel.

Export Classification

Determine whether products, drawings, software, or technical data are subject to export controls.

Customer and Destination Screening

Verify parties, destination, end use, and end user against applicable restrictions.

Government Clauses

Review applicable clauses, flowdowns, reporting, sourcing, inspection, and record-retention obligations.

Controlled Information

Identify cybersecurity, access, storage, transmission, and destruction requirements.

Domestic-Source Requirements

Determine whether material, components, or services require specific countries of origin.

Licensing

Confirm whether licenses, agreements, or customer authorization are required before access or shipment.

Contract Review Does Not Replace Legal or Export Advice

Organizations should route legal, regulatory, government-contract, export-control, and cybersecurity requirements to appropriately qualified personnel.

Commercial Terms and Conditions Review

The Purchase Order may incorporate customer terms and conditions by reference, hyperlink, attachment, portal, or prior agreement.

Commercial Term	Possible Risk
Payment Terms	Extended payment periods may affect cash flow.
Price	The order may not match the quotation or current material cost.
Warranty	Warranty length or scope may exceed the quoted assumptions.
Delivery Penalties	Late-delivery charges may create significant financial exposure.
Indemnification	The supplier may assume broad legal or financial responsibility.
Liability	Liability may be unlimited or disproportionate to the order value.
Intellectual Property	Ownership of designs, tooling, improvements, or manufacturing knowledge may be affected.
Termination	The customer may reserve broad rights to cancel without covering incurred cost.
Price Reduction	Automatic annual price reductions may not reflect actual cost.
Audit Rights	The customer may require access to facilities, systems, records, or suppliers.
Insurance	Required coverage may exceed existing policies.
Jurisdiction	Disputes may be governed by an unfamiliar or unfavorable jurisdiction.

Document Exceptions Before Acceptance

When the organization cannot accept a term, the exception should be communicated and resolved before order acknowledgment or performance begins.

Risk-Based Contract Review

Not every order requires the same review depth. A risk-based process assigns more extensive review to orders with greater technical, quality, financial, regulatory, or delivery risk.

Risk Level	Example	Suggested Review
Low	Repeat commercial item with unchanged revision and standard terms.	Streamlined review of quantity, price, date, revision, and exceptions.
Moderate	Repeat item with quantity increase, delivery change, or updated quality clauses.	Sales, planning, purchasing, and quality review.
High	New product, new process, challenging tolerances, or short lead time.	Full cross-functional review and formal risk assessment.
Critical	Safety-related, regulated, defense, export-controlled, or technically unprecedented work.	Management, legal, technical, quality, compliance, and executive approval.

Common Contract Risk Factors

New customer
New product
New revision
New material
New manufacturing process
New special-process supplier
Single-source material
Obsolete or allocation-controlled component
Short delivery schedule
Unfamiliar specification
Unproven tolerance capability
New inspection method
Customer penalties
High contract value
Low quoted margin
Export or regulatory restrictions
First Article Inspection
Customer approval before shipment
Long-term agreement
Unusual warranty or liability

Lifecycle-Based Contract Review

The review level should consider the history and lifecycle of the product.

Order Type	Primary Review Focus
First-Time Build	Complete technical, quality, purchasing, tooling, planning, cost, capacity, and risk review.
Prototype	Uncertain requirements, design maturity, development changes, inspection, and commercial assumptions.
Repeat Order	Revision, quantity, delivery, quality-clause, pricing, capacity, and supplier changes.
Revision Change	Technical differences, inventory impact, tooling, routing, inspection, cost, and first article.
Long Production Gap	Obsolete material, tooling condition, supplier availability, employee competency, and process validity.
Repair or Rework	Condition assessment, customer authorization, repair limits, disposition, and documentation.
Long-Term Agreement	Capacity, price adjustment, forecasts, material commitments, obsolescence, and cancellation terms.

Contract Amendments and Order Changes

Contract review does not end when the original order is accepted. Customer changes must be reviewed before they are incorporated into the Sales Order or production process.

Prevent Uncontrolled Changes

A customer email or verbal request should not automatically change production requirements. Changes should be documented, reviewed, approved, and communicated through the controlled process.

Managing Contract Review Action Items

A review should not be approved while unresolved issues remain hidden in comments or email threads.

Action Field	Purpose
Action Description	Defines the question, concern, missing information, or required task.
Responsible Person	Assigns accountability.
Due Date	Supports timely completion and customer acknowledgment.
Priority or Risk	Identifies actions that can prevent order acceptance.
Required Evidence	Defines what must be attached or documented before closure.
Status	Open, pending customer, completed, rejected, or cancelled.
Closure Approval	Confirms that the responsible reviewer accepts the resolution.

A contract review is complete only when all acceptance-blocking action items have been resolved or formally accepted as controlled risk.

Recommended Contract Review Approval Statuses

Status	Meaning
Pending	The review has been created but not all required reviewers have responded.
Approved	The reviewer has determined that applicable requirements can be met.
Approved with Conditions	The reviewer approves only when documented conditions are satisfied.
Clarification Required	Customer or internal information is required before a decision can be made.
Changes Required	The Purchase Order, quotation, delivery, price, or requirements must be amended.
Rejected	The organization cannot or should not accept the order as presented.
Cancelled	The review is no longer required because the order or opportunity was withdrawn.
Superseded	A later review or amendment replaced the original record.

Contract Review Records and Audit Evidence

The contract-review record should provide clear evidence of what was reviewed, who reviewed it, what issues were identified, and how the final decision was reached.

Customer Purchase Order
Quotation and quotation revision
Order acknowledgment
Applicable drawings and revisions
Specifications and quality clauses
Customer terms and conditions
Review classification and risk level
Assigned reviewers
Reviewer responses
Approval dates
Comments and conditions
Action items
Customer clarification records
Revised Purchase Orders
Contract amendments
Management or legal approvals
Final acceptance decision
Sales Order reference
Revision and change history

An Approval Checkbox Is Not Always Enough

The review record should make it possible to understand the requirements, evidence, exceptions, concerns, and basis for acceptance.

Common Contract Review Mistakes

Mistake	Better Approach
Reviewing only price and delivery	Review technical, quality, commercial, regulatory, documentation, and fulfillment requirements.
Accepting the order before review	Complete required approvals before order acknowledgment or release.
Assuming repeat orders are unchanged	Verify revision, clauses, dates, quantities, pricing, and referenced documents every time.
Relying on verbal clarification	Obtain written customer confirmation or an amended Purchase Order.
Using the same reviewers for every order	Assign reviewers according to risk and requirement type.
Approving with unresolved actions	Block acceptance until critical actions are closed.
Storing requirements only in attachments	Convert them into controlled Sales Order, purchasing, routing, inspection, and shipping requirements.
Ignoring customer terms	Route commercial, legal, warranty, and liability terms to qualified reviewers.
Failing to review amendments	Apply the same controlled review process to order changes.
Not comparing the Purchase Order with the quotation	Document every difference and resolve it before acceptance.
Allowing email to become the review system	Use a central workflow with assignments, statuses, records, and attachments.
Failing to communicate approved requirements	Connect the review with the Sales Order and downstream manufacturing records.

Contract Review Best Practices

Review quotations before they are issued.
Compare every Purchase Order with the final quotation.
Require a complete contract package before review.
Use risk-based review workflows.
Assign cross-functional reviewers automatically.
Review the latest drawing and specification revisions.
Identify all quality clauses and flowdown requirements.
Confirm supplier and outside-process availability.
Validate capacity and delivery dates.
Review inspection and test capability.
Identify First Article Inspection requirements.
Confirm lot, serial, heat, and batch traceability requirements.
Review packaging, preservation, labeling, and shipping requirements.
Route legal, commercial, export, and cybersecurity requirements appropriately.
Document every exception and customer clarification.
Use action items with owners and due dates.
Prevent order acceptance while required reviews are incomplete.
Control amendments and customer changes.
Connect approved requirements with the ERP Sales Order.
Maintain a complete audit history.
Measure review cycle time and recurring problems.
Use previous reviews to support repeat orders without blindly copying them.
Train reviewers on their responsibilities.
Periodically audit the contract-review process.

Contract Review KPIs

KPI	Purpose
Average Review Cycle Time	Measures the time from review creation to final approval.
On-Time Review Completion	Measures reviews completed by the required acknowledgment date.
Open Action Items	Tracks unresolved issues delaying order acceptance.
First-Pass Approval Rate	Measures reviews approved without clarification or amendment.
Purchase Order Discrepancy Rate	Measures orders that differ from the quotation.

Contract Amendments After Acceptance	Measures changes that require re-review.
Orders Rejected	Tracks work declined because requirements, risk, capacity, or terms were unacceptable.
Late Deliveries Caused by Review Failure	Measures delivery problems that should have been identified before acceptance.
Quality Escapes Related to Contract Requirements	Measures failures involving revisions, clauses, certifications, or customer requirements.
Unplanned Contract Cost	Tracks unquoted testing, inspection, documentation, packaging, or compliance costs.
Reviewer Response Time	Measures departmental responsiveness.

Why Electronic Contract Review Is Better Than Email or Paper

Manual Review Problem	Electronic Workflow Improvement
Review forms move by email or paper	All reviewers work from one controlled record.
Employees do not know review status	Dashboard displays pending, approved, rejected, and overdue reviews.
Attachments are distributed separately	Purchase Orders, drawings, clauses, and correspondence remain linked.
Approvals are difficult to verify	User, date, status, and comments are recorded automatically.
Actions are hidden in email	Actions receive owners, due dates, priorities, and statuses.
Reviewers forget to respond	Automated reminders and escalations can be sent.
Repeat reviews start from scratch	Previous review data can be copied and revalidated.
Audit preparation requires searching files	Complete review history can be retrieved from the order record.
Metrics require manual compilation	Cycle time, approvals, actions, and exceptions can be reported directly.

Electronic Review Improves Accountability

Every reviewer can see what is required, what remains open, who is responsible, and whether the order is ready for acceptance.

Frequently Asked Questions About Contract Review

What is contract review in manufacturing?

Contract review is the process of evaluating customer requirements before accepting an order. It confirms that technical, quality, delivery, pricing, regulatory, and commercial requirements are understood and achievable.

Why is contract review important?

Contract review prevents manufacturers from accepting orders they cannot fulfill as required. It reduces revision errors, missed clauses, unrealistic delivery promises, unplanned costs, disputes, rework, and customer dissatisfaction.

When should contract review occur?

Review should occur before quotation where practical, before accepting a new Purchase Order, and whenever the customer changes quantity, revision, delivery, price, quality requirements, terms, or other contractual conditions.

Who should participate in contract review?

Participation may include Sales, Engineering, Quality, Production, Planning, Purchasing, Materials, Inspection, Shipping, Finance, Legal, Export Compliance, and other functions affected by the order.

What should be reviewed on a customer Purchase Order?

Review part numbers, revisions, quantities, prices, dates, drawings, specifications, quality clauses, certifications, traceability, special processes, packaging, shipping, terms, regulatory obligations, and all referenced documents.

What is the difference between contract review and order entry?

Contract review determines whether the order should be accepted. Order entry records the accepted order in the ERP system.

Does every repeat order require contract review?

Yes, but the review may be streamlined. Repeat orders should still be checked for revision, quantity, delivery, quality-clause, pricing, supplier, and requirement changes.

How does contract review support ISO 9001?

It helps demonstrate that customer requirements are determined, reviewed before commitment, differences are resolved, capability is confirmed, and requirement changes are controlled.

How does contract review support AS9100?

It supports control of customer, product, quality, traceability, risk, special-process, configuration, regulatory, and other aerospace requirements before acceptance.

What happens when requirements conflict?

The organization should obtain written clarification, request an amended Purchase Order, issue a revised quotation, or document an accepted exception before committing to the order.

Can an order be conditionally approved?

Yes. Conditional approval should identify the exact conditions, responsible person, due date, and evidence required before release or fulfillment.

What should happen when a customer changes an accepted order?

The amendment should be reviewed for technical, quality, cost, schedule, purchasing, production, and regulatory impact before the Sales Order or manufacturing documents are changed.

What records should be retained?

Retain the Purchase Order, quotation, drawings, clauses, terms, reviewer approvals, comments, actions, customer clarifications, amendments, acceptance evidence, and final Sales Order reference.

Can contract review be automated?

Yes. Electronic workflows can assign reviewers, provide documents, collect approvals, track actions, send reminders, control release, and produce dashboards and reports.

How does SimpleManufacturing™ manage contract review?

SimpleManufacturing™ provides electronic cross-functional workflows, approvals, document access, action items, notifications, status dashboards, review history, metrics, and Sales Order integration.

Should quality clauses remain only as attachments?

No. Applicable clauses should also be translated into controlled purchasing, routing, inspection, traceability, documentation, packaging, and shipping requirements.

Can contract review prevent unprofitable orders?

It can identify unquoted testing, inspection, certification, tooling, packaging, supplier, documentation, warranty, or compliance costs before acceptance.

What is a risk-based contract review?

A risk-based process adjusts the number of reviewers and review depth according to factors such as new products, revisions, critical requirements, lead time, contract value, regulatory controls, and technical complexity.

Review Customer Requirements Before Accepting the Order

A strong contract-review process confirms that the organization understands the customer’s technical, quality, commercial, delivery, regulatory, and documentation requirements before making a commitment.

The process should involve the appropriate departments, identify risk, compare the Purchase Order with the quotation, resolve differences, document approvals, control amendments, and communicate approved requirements throughout the ERP system.

Prevent Problems Before Production Begins

The most effective time to resolve an incorrect revision, missing specification, unavailable supplier, unrealistic delivery date, quality clause, or unacceptable term is before the order is accepted.

SimpleManufacturing™ provides an electronic contract-review workflow connected with customers, quotations, Purchase Orders, documents, reviewers, action items, Sales Orders, production, quality, shipping, and reporting.
