Manufacturing Work Order Management Software: Complete Guide to Shop Floor Control

Manufacturing Work Order Management Software converts production demand into controlled instructions for materials, labor, routing operations, equipment, quality requirements, inventory transactions, completion reporting, costing, and finished-goods receipts.

A Work Order—also called a Job Order, Shop Order, Production Order, Manufacturing Order, or Service Order—authorizes the shop floor to perform a defined activity. That activity may involve building a finished product, manufacturing a subassembly, repairing an item, reworking nonconforming material, performing a customer service, upgrading equipment, or replenishing finished-goods inventory.

The Work Order becomes the central production record connecting the Item Master, Bill of Materials, manufacturing routing, customer order, inventory, purchasing, employees, equipment, inspection requirements, material traceability, actual cost, and completed product.

A manufacturing Work Order defines what must be produced, how many units are required, when they are due, which materials must be consumed, which operations must be completed, and how the resulting production cost and traceability history will be recorded.

Manufacturing Work Order workflow connecting customer demand, BOM materials, routing operations, labor, inspection, finished goods, and actual costing

Manufacturing Work Orders connect production demand with materials, routing operations, labor, quality, finished-goods inventory, and actual manufacturing cost.

What Is a Manufacturing Work Order?

A manufacturing Work Order is an internal authorization to produce, repair, rework, inspect, service, or modify a product, component, assembly, or piece of equipment.

The Work Order translates production demand into the information needed by the shop floor. It normally identifies:

The product, assembly, component, or service to be completed
The internal part number
The customer part number when applicable
The required revision
The quantity ordered
The quantity completed
The quantity remaining
The required completion date
The applicable Bill of Materials
The manufacturing routing or traveler
The material requirements
The work centers and equipment required
The employee labor transactions
The inspection and quality requirements
The lot or serial-number requirements
The customer order or inventory demand that created the requirement

Work Order, Job Order, Shop Order, and Production Order

Manufacturers use several terms for the record that authorizes production. The terminology varies by industry, company, and ERP system, but the underlying purpose is usually similar.

Term	Common Meaning
Work Order	A general authorization to manufacture, repair, rework, inspect, maintain, or service an item.
Job Order	Often used by job shops to identify customer-specific or project-specific manufacturing work.
Shop Order	An instruction released to the production floor to complete manufacturing activity.
Production Order	A formal order to manufacture a defined quantity of a product or assembly.
Manufacturing Order	A production record connecting materials, processes, labor, quantities, dates, and cost.
Service Order	An authorization to perform repair, maintenance, installation, inspection, or another service.
Rework Order	A controlled order used to correct or modify nonconforming or returned product.
Repair Order	An order used to restore equipment or product to an acceptable condition.

This guide uses “Work Order” as the primary term, but the same principles generally apply to Job Orders, Shop Orders, Production Orders, and Manufacturing Orders.

Why Work Orders Are Important in Manufacturing

A Work Order provides one controlled source for coordinating materials, production operations, employees, equipment, quality requirements, due dates, quantities, inventory transactions, and manufacturing cost.

Production Authorization

The Work Order formally communicates what the shop floor is authorized to produce or perform.

Material Planning

BOM requirements become visible to inventory, purchasing, kitting, and Material Requirements Planning.

Process Control

Routing operations define the required sequence, instructions, work centers, tools, fixtures, and inspections.

Real-Time Visibility

Managers can review production status, current operation, shortages, completed quantities, and due-date risk.

Traceability

Material lots, serial numbers, suppliers, operations, employees, inspections, and finished products remain connected.

Actual Costing

Material, labor, outside processing, machine burden, and overhead can be accumulated by Work Order.

Production Activity Without Work Orders Creates Gaps

When materials, labor, inspections, rework, and completions are recorded separately, manufacturers may lose visibility into what was consumed, who performed the work, which revision was produced, and what the finished product actually cost.

What Information Does a Work Order Contain?

Work Order Information	Purpose
Work Order Number	Provides a unique internal production reference.
Work Order Type	Identifies production, repair, rework, service, subcontract, prototype, or other activity.
Internal Part Number	Identifies the product throughout the ERP system.
Customer Part Number	Provides the customer-facing product reference when applicable.
Revision	Defines the required product configuration.
Description	Explains the product, assembly, or task.
Quantity Ordered	Defines the quantity authorized for production.
Quantity Completed	Records accepted finished production.
Quantity Rejected	Records failed or nonconforming production.
Quantity Remaining	Identifies the balance still requiring completion.
Release Date	Defines when production is authorized to begin.
Due Date	Defines when production must be completed.
Customer Order Reference	Connects production with customer demand.
Sales Order Line or Delivery Schedule	Connects the Work Order with a specific customer requirement.
Bill of Materials	Defines required components and quantities.
Routing	Defines manufacturing and inspection operations.
Quality Requirements	Identifies inspections, certifications, specifications, and customer clauses.
Lot or Serial Requirements	Defines product identification and traceability.
Priority	Supports scheduling and production decision-making.
Status	Identifies the current stage of the Work Order lifecycle.

Common Manufacturing Work Order Types

Work Order Type	Purpose
Customer Work Order	Produces an item for a specific Sales Order or customer delivery.
Stock Work Order	Replenishes finished-goods or subassembly inventory.
Rework Work Order	Corrects nonconforming product or production defects.
Repair Work Order	Repairs customer-owned, company-owned, or returned equipment.
Prototype Work Order	Builds development or preproduction items.
Engineering Work Order	Supports design validation, testing, or engineering changes.
Service Work Order	Controls installation, maintenance, calibration, inspection, or field service.
Outside Processing Work Order	Tracks manufacturing activity sent to subcontractors.
Disassembly Work Order	Breaks down an assembly into reusable or inspectable components.
Conversion Work Order	Converts one material, configuration, or inventory stage into another.

Turnkey and Consignment Work Orders

Contract manufacturers frequently distinguish Work Orders according to who provides the material.

Classification	Material Responsibility	Operational Impact
Turnkey Work Order	The manufacturer purchases and controls the required materials and services.	Purchasing, inventory, supplier management, material costing, and production are managed internally.
Consignment Work Order	The customer provides some or all required material.	Customer-owned material must be received, identified, stored, consumed, reconciled, and reported separately.

Consignment Material Controls

Customer ownership
Customer packing-slip reference
Quantity received
Lot or serial number
Storage location
Material condition
Quantity issued
Quantity consumed
Quantity scrapped
Quantity returned
Customer authorization for disposition

Customer-Owned Material Still Requires Control

Consigned material should remain traceable even when it does not represent company-owned inventory value.

How Manufacturing Work Orders Are Created

Work Orders may originate from several sources depending on the manufacturer’s production strategy.

Sales Orders

Make-to-order manufacturers may create Work Orders directly from customer order lines or scheduled deliveries.

Material Requirements Planning

MRP recommends Work Orders when finished goods or subassemblies must be manufactured to satisfy demand.

Minimum Inventory Levels

Reorder points, Kanban signals, and minimum stock rules can trigger inventory-replenishment Work Orders.

Quality Records

Nonconforming material, inspection failures, and corrective actions may create rework or repair Work Orders.

Engineering Requirements

Prototype, testing, qualification, or engineering-change activity may require controlled production.

Manual Entry

Authorized users may create a Work Order for one-time, service, repair, or unusual production requirements.

Connecting Work Orders with Customer Sales Orders

In make-to-order and job-shop environments, the Work Order may be linked directly to a customer Sales Order line or delivery schedule.

This relationship allows users to identify:

Which customer created the demand
Which customer Purchase Order applies
Which Sales Order line is being produced
Which delivery date must be supported
Which customer part number applies
Which product revision is required
Which customer quality clauses apply
Which shipment will fulfill the demand
Whether enough quantity has been produced
Whether the Work Order is threatening customer delivery

Learn more in our Manufacturing Order Management Software guide.

Creating Work Orders Through Material Requirements Planning

MRP evaluates customer demand, forecasts, inventory, open Purchase Orders, open Work Orders, Bills of Materials, lead times, and planning policies.

For manufactured items, MRP can recommend:

New planned Work Orders
Recommended Work Order quantities
Required release dates
Required completion dates
Work Orders that should be expedited
Work Orders that can be deferred
Work Orders that may no longer be required
Subassembly Work Orders
Parent and child Work Order relationships

MRP uses the Work Order as the planned source of manufactured supply, just as a Purchase Order represents planned purchased supply.

Learn more in our Material Requirements Planning guide.

Multi-Level BOM Work Orders

A multi-level Bill of Materials may include manufactured subassemblies that require their own Work Orders.

The Manufacturing Work Order Lifecycle

Lifecycle Stage	Activity
Planned	The requirement exists but has not been formally released.
Created	The Work Order record, material requirements, and routing have been generated.
Reviewed	Materials, routing, revision, quality, quantities, dates, and requirements are verified.
Kitted	Required inventory is reserved, picked, staged, or issued.
Released	The shop floor is authorized to begin production.
In Process	Manufacturing operations, labor, material, and quantities are being recorded.
Inspection	Production is undergoing required acceptance activity.
Partially Complete	Some finished quantity has been accepted and received.
Complete	The required quantity has been produced or otherwise resolved.
Costed	Material, labor, outside processing, and overhead have been accumulated.
Closed	Production, material reconciliation, quality, cost, and remaining actions are complete.

Recommended Work Order Statuses

Status	Meaning
Draft	The Work Order is being prepared and is not available for production.
Planned	The Work Order represents expected supply but has not been released.
Pending Material	Required components are not yet available.
Ready to Kit	Material is available for picking or allocation.
Kitted	Material has been staged or issued.
Released	Production is authorized to begin.
In Process	One or more routing operations are active.
Waiting	The Work Order is waiting for material, equipment, outside processing, approval, or another dependency.
Outside Processing	Material is currently at a subcontractor.
Inspection	Production is awaiting or undergoing quality acceptance.
Partially Complete	Some quantity has been completed while additional quantity remains open.
Complete	Production quantity is finished.
Closed	All material, labor, quality, cost, and administrative activity is complete.
On Hold	The Work Order has been temporarily stopped.
Cancelled	The remaining production requirement will not be completed.

Work Order Material Requirements

The Bill of Materials is normally the source of the Work Order’s material requirements.

Each material requirement may include:

BOM line number
Internal part number
Customer part number
Manufacturer
Manufacturer part number
Approved supplier
Supplier part number
Quantity per assembly
Total quantity required
Unit of measure
Need date
Quantity allocated
Quantity issued
Quantity returned
Quantity remaining to consume
Alternate or substitute components
Lot or serial-number requirements
Quality and certification requirements

Material Need Dates Should Support the Routing

All components may not be required at the beginning of production. A material need date can align each component with the operation where it will be consumed.

Identifying and Resolving Work Order Material Shortages

Because each Work Order includes a quantity, due date, BOM, and routing, the ERP system can identify expected shortages before the shop floor reaches the affected operation.

Shortage Source	Possible Response
Insufficient Inventory	Create or expedite a Purchase Order or Work Order.
Material in Receiving Inspection	Prioritize inspection when appropriate.
Late Supplier Delivery	Expedite, reschedule, or source from an alternate approved supplier.
Late Subassembly	Prioritize or reschedule the child Work Order.
Material Allocated Elsewhere	Review priorities and reallocate inventory.
Rejected Material	Initiate replacement supply or approved disposition.
Incorrect BOM Quantity	Correct the requirement through controlled change.
Unexpected Scrap	Issue replacement material and record the cause.

Shortage visibility is most valuable before production is interrupted. Work Order planning allows purchasing, inventory, quality, and production teams to address risk in advance.

Work Order Kitting and Material Picking

Kitting is the process of identifying, reserving, picking, staging, and issuing the materials required by a Work Order.

Manufacturers may use several kitting strategies:

Kitting Strategy	Description
Complete Kit Before Release	All required materials are staged before the Work Order is released.
Partial Kit	Available material is staged while shortages remain open.
Operation-Based Kitting	Material is issued as each routing operation requires it.
Point-of-Use Material	Common materials are stored and consumed at the work center.
Backflushing	Material is automatically consumed based on completed production quantity.
Auto-Kit	The ERP system allocates and issues material into Work in Process automatically.
Manual Issue	Employees select and issue specific inventory layers, lots, or serial numbers.

FIFO Material Issues and Actual Material Cost

SimpleManufacturing™ can identify inventory for Work Order consumption using FIFO—First-In, First-Out—so the oldest available inventory cost layers are consumed first.

Each material issue can retain:

FIFO inventory layer
Quantity issued
Actual unit cost
Extended cost
Purchase Order
Purchase Order line
Receipt date
Supplier
Manufacturer
Lot number
Date code
Serial number
Material certification

Purchase
Receipt

➜

Learn more in our FIFO Inventory Costing guide and Actual Work Order Costing guide.

Alternate and Substitute Materials

Approved alternates and substitutes can help production continue when the preferred component is unavailable.

Alternate control should identify:

Approved alternate part number
Approved manufacturer
Approved supplier
Applicable customer
Applicable product revision
Effective date
Required approval
Quality and inspection requirements
Cost difference
Traceability requirements

Availability Does Not Equal Approval

A component should not be substituted merely because it is in stock. The substitute must satisfy engineering, customer, quality, regulatory, and configuration requirements.

Managing Excess Kitted Material

Some manufacturers intentionally issue more material than the exact BOM requirement to support setup, testing, handling loss, or expected scrap.

The Work Order should distinguish:

Required material
Excess material issued
Material consumed
Material scrapped
Unused material
Material returned to inventory

Required and Excess
Material Issued

➜

Production
Consumption

➜

Unused Quantity
Identified

➜

Return to
Inventory

Returning unused material prevents excess Work Order cost and restores accurate available inventory.

Work Order Material Transaction History

Every material movement should remain connected with the Work Order.

Material Transaction	Purpose
Allocation	Reserves inventory for the Work Order.
Pick	Identifies material selected from inventory.
Issue	Transfers material into Work in Process.
Additional Issue	Records replacement or unexpected material consumption.
Return	Restores unused material to inventory.
Scrap	Records unusable material and its cost.
Substitution	Records use of an approved alternate component.
Transfer	Moves staged material between work centers or locations.

Work Order Router, Traveler, and Job Card

The manufacturing routing defines the planned sequence of operations required to complete the Work Order.

A routing operation may identify:

Operation number
Operation description
Work center
Machine or equipment
Setup instructions
Production instructions
Tools and fixtures
Setup time
Run time
Queue time
Move time
Employee skill requirements
Inspection requirements
Outside processing requirements
Required documents
Estimated labor cost
Machine burden rate

The Work Order traveler or job card communicates these instructions to the shop floor and records progress through the routing.

Creating the Work Order Routing from the Product Definition

When the Work Order is created, SimpleManufacturing™ can copy the approved routing and process requirements associated with the product or Bill of Materials.

This helps ensure that each Work Order begins with the controlled production definition, including:

Operation sequence
Work centers
Instructions
Tooling
Fixtures
Setup and run times
In-process inspections
First-piece inspections
First Article Inspection requirements
Outside processing
Packaging and final acceptance

As-Planned vs. As-Built

The released routing represents the planned process. Approved changes made during production can be recorded as part of the Work Order’s as-built history and evaluated for incorporation into the product master.

Managing Work Order Routing Operations

Operation Activity	Information Recorded
Operation Release	Authorizes the operation to begin.
Employee Clock-In	Records the employee and start time.
Setup Completion	Records setup time and readiness.
Production Reporting	Records quantity processed and production time.
Inspection	Records measurements, acceptance, rejection, and inspector.
Operation Transfer	Moves accepted quantity to the next operation.
Rework	Routes rejected quantity through corrective operations.
Outside Processing	Records quantity sent to and received from a supplier.
Operation Completion	Confirms the operation is finished.

Work Order Labor Collection

Employees can record labor directly against Work Order operations.

Labor transactions may include:

Employee
Work Order
Operation
Work center
Start time
Stop time
Setup time
Production time
Indirect time
Quantity completed
Quantity rejected

Production Quantity Reporting

Operators should be able to record quantities as production moves through each operation.

Quantity Type	Meaning
Quantity Started	Units entering the operation.
Quantity Completed	Units successfully processed.
Quantity Accepted	Units meeting inspection requirements.
Quantity Rejected	Units failing acceptance requirements.
Quantity Reworked	Units routed through corrective processing.
Quantity Scrapped	Units permanently removed from production.
Quantity Transferred	Units moved to the next operation.
Quantity Remaining	Units still requiring processing.

Partial Work Order Completion

Manufacturers may need to complete and receive part of a Work Order before the entire authorized quantity is finished.

Partial completion can support:

Urgent customer shipments
Scheduled delivery releases
Revenue requirements
Long production runs
Progressive assembly
Subcontract production
Limited material availability
Quality release of accepted quantities

Cost Partial Completions Consistently

The ERP system should define how accumulated material, labor, outside-processing, and overhead costs are assigned to each completed quantity.

Quality Requirements on Work Orders

Customer, product, process, regulatory, and internal quality requirements should flow into the Work Order and its routing operations.

Work Order quality requirements may include:

First-piece inspection
First Article Inspection
In-process inspection
Final inspection
Source inspection
Customer inspection
Control-plan requirements
Key characteristics
Critical characteristics
Sampling plans
Test requirements
Certificate of Conformance
Material certifications
Process certifications
Lot or serial traceability
Customer quality clauses
Packaging, preservation, and labeling

Quality requirements should be linked to the operation where they apply instead of appearing only as general notes on the Work Order.

First-Piece and First Article Inspection

A routing operation can require inspection before additional production proceeds.

Inspection Type	Purpose
First-Piece Inspection	Verifies setup and process output before continuing production.
First Article Inspection	Provides documented verification that the complete production process can produce a conforming item.
In-Process Inspection	Verifies characteristics during manufacturing.
Final Inspection	Confirms completed product meets release requirements.
Source Inspection	Allows the customer or another authorized party to inspect before shipment.

Rework and Repair Work Orders

Rework and repair activity should be controlled separately from the original production process when additional operations, approvals, material, labor, or inspection are required.

A rework Work Order may identify:

Original Work Order
Nonconformance record
Affected part number and revision
Lot or serial number
Quantity requiring rework
Approved disposition
Rework instructions
Required replacement material
Additional labor
Required inspection
Customer approval
Rework cost
Final acceptance

Outside Processing Work Order Operations

Manufacturing operations such as plating, anodizing, heat treatment, painting, testing, calibration, or specialty machining may be performed by outside suppliers.

The Work Order should connect outside processing with:

Routing operation
Approved supplier
Purchase Order
Quantity sent
Quantity received
Required date
Supplier promise date
Process specification
Required certifications
Lot or serial traceability
Outside-processing cost
Rejected or lost quantity

Learn more in our Manufacturing Purchase Order guide.

Work Order Scheduling

Work Order scheduling coordinates customer demand with materials, labor, equipment, work centers, outside processing, inspections, and due dates.

Scheduling may consider:

Customer priority
Sales Order due date
Work Order due date
Material availability
Child Work Order dependencies
Routing sequence
Work-center capacity
Machine availability
Employee availability
Tooling availability
Outside processing lead time
Inspection capacity
Queue and move time

Due Date Alone Is Not a Production Schedule

A realistic Work Order schedule must account for material, routing, dependencies, capacity, and required inspection activity.

Completing a Manufacturing Work Order

Work Order completion records accepted finished production and transfers accumulated manufacturing cost into finished-goods inventory or the appropriate completed output.

Before final closure, the system should verify:

Required quantity is complete or otherwise resolved
All routing operations are complete
Required inspections are accepted
All material issues are recorded
Unused material is returned
Scrap and rework are recorded
Labor transactions are complete
Outside processing is received and costed
Lot or serial numbers are assigned
Required certifications are available
Finished goods are received into inventory
Actual cost is calculated
Remaining actions are closed

Completing production and closing a Work Order are not always the same event. Closure should occur only after material, labor, quality, cost, and documentation are reconciled.

Finished-Goods Inventory Receipt

When accepted production is completed, the finished product can be received into inventory.

The finished-goods record may include:

Internal part number
Revision
Work Order number
Completion date
Quantity completed
Inventory location
Lot number
Serial number
Expiration date when applicable
Actual unit cost
Total inventory value
Inspection status
Customer or Sales Order relationship

Work Order Accounting Integration

Manufacturing transactions can automatically update inventory and financial records behind the scenes.

Manufacturing Transaction	Typical Debit	Typical Credit
Material Issue	Work in Process	Raw Material Inventory
Direct Labor Applied	Work in Process	Accrued Payroll or Applied Labor
Outside Processing	Work in Process	Accounts Payable or Accrued Liability
Manufacturing Overhead	Work in Process	Applied Overhead
Work Order Completion	Finished Goods Inventory	Work in Process
Shipment	Cost of Goods Sold	Finished Goods Inventory

The exact account structure depends on the manufacturer’s accounting policies and configured chart of accounts.

Real-Time Financial Visibility

Integrated Work Order transactions help accounting and management understand:

Raw-material inventory value
Work-in-Process inventory value
Finished-goods inventory value
Material committed to production

Common Work Order Management Problems

Problem	Possible Result	Better Control
Wrong Product Revision	Production creates an obsolete or unacceptable configuration.	Validate Item Master, drawing, BOM, routing, and customer revision before release.
Incomplete BOM	Production experiences shortages or uses undocumented material.	Review material requirements before release.
Incorrect Quantity	Excess or insufficient production occurs.	Connect the Work Order with the original demand.
Unrealistic Due Date	The Work Order is late before production begins.	Review material, capacity, routing, and dependencies.
Material Issued Outside the Work Order	Inventory and actual cost become inaccurate.	Record every material transaction against the Work Order.
Labor Not Recorded	Production cost and efficiency reporting are incomplete.	Collect labor at each routing operation.
Operations Completed Out of Sequence	Product quality or traceability may be compromised.	Use controlled routing and transfer rules.
Quality Requirements Hidden in Notes	Required inspections or certifications are missed.	Link requirements with specific operations.
Unused Material Not Returned	WIP cost is overstated and available inventory is understated.	Reconcile material before closure.
Work Order Closed Too Early	Material, labor, cost, or inspection data remains incomplete.	Use formal closure validation.

Frequently Asked Questions About Manufacturing Work Orders

What is a manufacturing Work Order?

A manufacturing Work Order is an internal authorization to produce, repair, rework, inspect, service, or modify an item according to defined material, process, quality, quantity, and due-date requirements.

What is the difference between a Work Order and a Job Order?

The terms are often used interchangeably. Job Order is common in job-shop and customer-specific manufacturing, while Work Order is a broader term used for production, repair, service, and rework activity.

What is a Shop Order?

A Shop Order is a production instruction released to the manufacturing floor. It normally identifies the product, quantity, routing, materials, due date, and production requirements.

What information should a Work Order contain?

A Work Order should identify the product, revision, quantity, due date, BOM, routing, materials, quality requirements, customer demand, lot or serial requirements, operations, labor, and completion status.

How are Work Orders created?

They may be created from Sales Orders, MRP recommendations, inventory-replenishment rules, Kanban signals, quality records, engineering requirements, or manual entry.

How does MRP create Work Orders?

MRP compares demand with inventory and open supply, then recommends manufactured quantities and dates for items that must be produced.

What is Work Order kitting?

Kitting is the process of identifying, reserving, picking, staging, and issuing materials required for production.

Can material be issued by FIFO?

Yes. FIFO allocation uses the oldest available inventory layers first and transfers their actual material costs into the Work Order.

Can a Work Order use substitute material?

Yes, when the substitute is formally approved for the product, customer, revision, and applicable quality requirements.

What is a Work Order routing?

The routing defines the planned sequence of manufacturing, inspection, outside processing, and handling operations required to complete production.

How is labor recorded?

Employees record setup and production time against Work Order operations. The system uses those transactions to monitor progress and calculate actual labor cost.

Can a Work Order be partially completed?

Yes. Accepted quantities may be completed and received before the entire Work Order quantity is finished when the manufacturer’s process permits partial completion.

What is a rework Work Order?

A rework Work Order controls the additional operations, materials, labor, inspections, and approvals required to correct nonconforming product.

How are outside-processing operations managed?

The Work Order routing connects the outside operation with an approved supplier, Purchase Order, quantity, specification, certification, due date, and cost.

How does a Work Order support traceability?

It connects material receipts, lots, serial numbers, suppliers, employees, routing operations, inspections, finished products, and customer shipments.

How is actual Work Order cost calculated?

Actual cost combines inventory materials consumed, direct labor, machine burden, outside processing, overhead, scrap, and rework according to the manufacturer’s costing policies.

What happens when a Work Order is completed?

Accepted production is received into finished-goods inventory, accumulated cost is transferred from Work in Process, and the resulting product becomes available for shipment or future demand.

What accounting entries are created?

Material issues typically transfer cost from Raw Material Inventory into WIP. Completion transfers cost from WIP into Finished Goods, and shipment transfers cost into Cost of Goods Sold.

When should a Work Order be closed?

Closure should occur after quantities, material, labor, outside processing, inspections, certifications, finished-goods receipts, cost, and remaining actions have been reconciled.

What is a turnkey Work Order?

A turnkey Work Order means the manufacturer or subcontractor is responsible for procuring and controlling the materials and services needed to complete the order.

What is a consignment Work Order?

A consignment Work Order uses customer-provided material that must be separately identified, stored, consumed, reconciled, and returned or dispositioned.
