Manufacturing Order Template: BOM, WIP Accounting, and Cost Variance

The problem in most Saudi factories starts with a simple question: “How much did this batch actually cost us to produce?” The question sounds routine, but answering it without a complete manufacturing order requires a long session between production, the warehouse, and accounting, and usually ends with rough estimates that match neither inventory records nor the labor costs actually logged.

A manufacturing order (also called a production order) is the document that closes this gap. It is not just an internal request to start a production line, it is a complete container that brings together the target product, the standard Bill of Materials (BOM), quantities, expected runtime, the assigned production line, direct and manufacturing overhead costs, and the flow from “raw materials” to “work in process” to “finished goods”. The difference between an organized factory and one that runs production by guesswork starts exactly here.

In this practical guide we build the manufacturing order from scratch: precise definition, the difference between manufacturing orders, work orders, and purchase orders, components, the full production cycle, the BOM and how to design it, the order’s impact on inventory and the related accounting entries, direct and manufacturing overhead costs, a numerical example for a furniture factory in Riyadh, the most common mistakes, Zakat, Tax and Customs Authority (ZATCA) requirements for factories, and finally how Qoyod turns all of this into an automated monthly cycle linked directly to the general ledger.

What is a manufacturing order? A practical definition for Saudi factories

A manufacturing order is a formal document issued by production management to authorize a specific production line to manufacture a defined quantity of a specific product within a defined time window, with the necessary resources allocated. The order carries a unique serial number, ties to a specific cost center, and becomes the primary unit for accumulating every expense related to that production batch after issuance.

To simplify the idea, imagine the factory as a large machine and the manufacturing order as the “ignition key” for one part of it to produce a specific product. Without this key, any material pulled from the warehouse or any labor hour logged on the production line stays suspended without a clear container to absorb it, building up what is accounting-speak called “unallocated costs”, the nightmare that makes a factory’s monthly profitability report unreadable.

The manufacturing order achieves three inseparable goals:

• Planning: it turns sales forecasts or customer orders into an executable production plan with defined quantities and dates.
• Control: it links every actual expense (materials, labor, energy, maintenance) to the production batch that consumed it, so any variance shows up later with precision.
• Accounting: it opens a WIP sub-account for the order, closes it on completion, and transfers the cost to finished goods at an auditable value.

Small factories often ask: do we need a formal manufacturing order for every batch, or can we just produce on demand? The practical answer: if you produce more than one product, run more than one production line, or want to know the true profit margin per product, you need manufacturing orders from day one. The chaos you avoid later is worth the upfront effort.

The difference between a manufacturing order, a work order, and a purchase order

Mixing these three is one of the most common mistakes that confuse young factories, especially during the move from paper management to an integrated accounting system. Each document has a different purpose, is issued by a different department, and is booked through a different journal entry.

Manufacturing order (production order)

Issued internally by production management. Its purpose is to manufacture a product to increase its inventory balance. It does not involve any external party, it simply moves balances between internal accounts: raw materials, WIP, and finished goods. The accounting entry links inventory accounts to each other without touching supplier or customer accounts.

Work order (job order)

Broader in concept, used in service or specialized industries (maintenance workshops, installation, made-to-order manufacturing). It usually involves an external party (a customer) waiting for the delivery of a service or a custom product. In large process manufacturing, a work order is used as a general umbrella that can branch out into several manufacturing orders for each stage.

Practical rule: if you produce standard inventory for later sale, you use a manufacturing order. If you execute a custom project for a customer (installation, assembly, maintenance), you use a work order. Many factories use both together, and they eventually meet in the same project or product profitability report.

Purchase order

Issued by the procurement department and directed to an external supplier. Its purpose is to buy raw materials or services needed for production, not to manufacture a product. The accounting entry when a purchase order is issued is a commitment that does not show up in actual financials until the materials are received, where the entry becomes: raw materials debit, accounts payable credit. To review the double-entry mechanism in detail, you can return to the guide on the difference between debit and credit in double-entry bookkeeping.

The relationship between the three in an integrated factory: a purchase order brings in raw materials, a manufacturing order converts them into a finished product, a work order (when needed) ties the product to a specific customer project. Any break in this sequence loses the link between material cost and finished product value.

Detailed components of a manufacturing order

Any manufacturing order missing one of these components enters the production cycle with high risk. The minimum acceptable framework for an order that can be tracked in accounting:

1. Formal header

• Serial number: a unique code (e.g., MO-2026-00184) that links the order to every subsequent transaction.
• Issue date and planned delivery date: the gap between them equals the expected production cycle.
• Cost center: the line or department where costs will be charged.
• Issuer and approver: at least two signatures to ensure separation between issuance and approval.

2. Definition of the finished product

Product name, product catalog code, requested quantity, unit of measure, and the technical specifications that distinguish this batch (color, size, packaging). An order that produces 500 units without defining the specs creates a gap between what was actually requested and what came out of the factory.

3. Bill of Materials (BOM)

All raw materials and sub-components required, with their standard quantities, and the source of each item (local warehouse, imported material, semi-finished from another manufacturing order). This list is built once per standard product, then copied whenever a new order is issued. The BOM is so foundational that we dedicate a separate section to it below.

4. Standard labor hours and direct labor

How many work hours does it take to produce a single unit? From which specialty (welder, lathe operator, finishing worker)? This estimate later determines the labor variance. In Saudi factories, direct labor wages are calculated under the Saudi Labor Law and the GOSI subscription requirements, so the actual hourly rate for each specialty should be kept up to date to make cost allocation accurate.

5. Manufacturing overhead

Not every cost can be traced to the order directly. Electricity, rent, machine maintenance, supervisor salaries, depreciation: these are pooled monthly and allocated to orders via an overhead rate. The most common method is to multiply direct labor hours by an hourly overhead rate (calculated annually from total expected manufacturing overhead divided by total expected labor hours).

6. Quality stage and acceptance criteria

Define the allowed scrap rate, the inspection criteria, and who inspects. Setting a standard scrap rate matters; without it, you have no basis for calculating quality variance. If an order finishes with 12% scrap while the standard is 5%, that is an accounting gap that needs explanation, not silence.

7. Operational tracking fields

Actual start date, actual end date, quantity produced, defective quantity, name of the responsible operator, and any notes on the batch. These fields may look like formality, but they are what turns the order from a static document into an operational analysis tool.

The manufacturing cycle from planning to delivery

The production cycle through a manufacturing order passes through six stages, each reflected by an accounting entry that moves balances. Understanding these entries is essential for anyone running a factory’s accounting, because it is the difference between a correct monthly profitability report and a random one.

Stage one: planning

It starts from a forecast or a confirmed customer order. Production management uses sales forecasts and the inventory projection file to decide whether current plus planned production is enough to cover expected demand. When a gap appears, the order is born. No accounting entry is recorded at this stage, the process is purely planning.

Stage two: issuing the order

Planning is converted into a formal numbered order. A standard budget for the order (materials, labor, manufacturing overhead) is prepared. The accounting system opens a sub-account for the order under WIP. No real entry yet, just a sub-account ready to receive.

Stage three: gathering the materials

A material issue note from the warehouse is recorded. The entry:

• Debit: Work in process (Order MO-…) at the value of materials issued
• Credit: Raw materials inventory at the same value

This entry moves the material’s value from “asset in the warehouse” to “asset in production”. The physical raw materials inventory drops, and the financial WIP balance rises. To deepen your understanding of how this movement affects the financial statements and the calculation of cost of goods sold, see the COGS guide.

Stage four: execution on the production line

Every actual cost is charged to the order:

• Direct labor wages at actual hours times the hourly rate.
• Any additional materials issued beyond the estimate (due to scrap or error).
• Manufacturing overhead applied at the overhead rate.

The entry for each component:

• Debit: Work in process (the order)
• Credit: Wages payable, or raw materials inventory, or manufacturing overhead applied

Stage five: quality

When production is inspected, accepted and defective units are identified. The cost of defective units is treated according to factory policy: if within standard, it is charged to the order’s cost, if above standard, it is moved to a “scrap variance” account and shows up in the monthly variance report. This detail also links to the concept of material variance analysis, which breaks down the causes of variance between quantities and prices.

Stage six: closing the order

When production is complete, accepted quantities are transferred to finished goods. The entry:

• Debit: Finished goods inventory at the total order cost
• Credit: Work in process (the order) at the same value

Now the order’s WIP balance becomes zero (in principle), and actual unit cost equals total order cost divided by accepted units. This cost is compared with the standard cost, and any difference is recorded as a variance.

Bill of Materials (BOM) in detail

The BOM is the heart of the manufacturing order. It is the record that defines precisely what goes into producing one unit of the product, in what quantities, and to what specs. A factory without an accurate BOM runs production on guesswork, and explains end-of-month variances with operational excuses that have no accounting basis.

Standard BOM elements

• Material code: a unique identifier for each material in the warehouse catalog, linking it to inventory transactions.
• Material name and specs: must be clear to the person issuing materials and to the cost accountant.
• Unit of measure: kg, meter, liter, piece. A unified unit from purchase through production prevents errors.
• Standard quantity per unit of output: the most important number in the list; scrap is calculated from it later.
• Standard allowed scrap: the naturally expected scrap rate in production (e.g., 2% cutting scrap in wood).
• Preferred supplier and alternatives: when a material is out of stock, you know what approved alternatives exist.

Multi-level BOM structure

In complex industries, the finished good is made up of semi-finished goods, which in turn require their own raw materials. Here the BOM appears as a tree:

• Level zero: the finished product.
• Level one: semi-finished sub-assemblies.
• Level two and beyond: core raw materials.

Each level needs a separate manufacturing order in some factories, which makes the production cycle a chain of interlinked orders, where the output of one order becomes the input of another. The accounting system must handle this chain without manual work.

Issuing and updating the BOM

The BOM is a living document. Every change in product design, every material change driven by market availability, and every production process improvement should be reflected by a new BOM version. Orders in progress finish on the old version, and new orders use the updated version. Mixing the two produces costs that cannot be compared.

Linking the manufacturing order to inventory

A factory manages three types of inventory, and every manufacturing order moves balances between them:

1. Raw materials

Materials the factory bought to use in production but that have not yet entered any manufacturing operation. They are recorded at cost (purchase price plus import expenses plus customs if any). When materials are issued to a manufacturing order, this inventory balance drops by the value of the materials issued.

2. Work in process (WIP)

Quantities that have started manufacturing and have not finished yet. This balance is cumulative: the value of materials plus labor plus manufacturing overhead. Every manufacturing order has its own sub-balance in this account. An order that stays open for a month carries a value that changes every time a new cost is added.

3. Finished goods

Quantities that have finished manufacturing, been inspected, and been accepted, ready for sale. When a unit is sold, its value moves to COGS and is deducted from the balance.

The costing method (FIFO, LIFO, weighted average) determines how inventory issuance is recorded. The most common in Saudi factories is the weighted average cost method, especially for raw materials bought in batches at different prices. Manual application of this method in Excel is possible, but as issuance transactions stack up it becomes impractical and requires an accounting system that recalculates it automatically after each transaction.

If you manage a trading business or a small factory and are looking for a wider view of inventory management inside an accounting system, the inventory management section on the Qoyod blog provides a complete series of practical guides. To understand deeper contexts like just-in-time (JIT) production, it is worth a read, as it is an operating philosophy that drives WIP balances to their minimum.

Direct and manufacturing overhead costs

Total manufacturing order cost equals direct costs plus manufacturing overhead. Separating these two types is the foundation of manufacturing cost accounting.

Direct costs

• Direct materials: every material that physically goes into the finished product and is traceable by quantity (the wood in a chair, the flour in a cake). Charged to the order directly at quantity issued times unit cost.
• Direct labor: wages of workers who actually work on producing the product, at the hours logged on the order. Wages include basic pay plus taxable allowances plus the employer share of GOSI.

Manufacturing overhead

Costs that cannot be traced to a specific product but are necessary to run the factory:

• Factory and warehouse rent
• Electricity, water, fuel
• Machine maintenance and spare parts
• Depreciation of machines and equipment
• Salaries of supervisors and production management
• Insurance on equipment and inventory

These costs are pooled monthly into a “manufacturing overhead” account, then allocated to orders using an overhead rate. Common methods:

• Allocation based on direct labor hours (most common in labor-intensive factories).
• Allocation based on machine hours (in automated factories).
• Allocation based on direct materials value (in material-intensive factories).

Choosing the allocation method is not arbitrary. It must reflect the factor that drives overhead costs the most. A wrong choice produces an unfair allocation across products, so profitable products appear unprofitable and vice versa. For a deeper understanding of profitability metrics and how they are calculated, the profit margin guide is useful.

A practical example: a furniture factory in Riyadh

Let us see the idea in real life. A mid-sized factory in Riyadh produces office chairs and received an order from a company to furnish its offices with 100 chairs. Manufacturing order MO-2026-00184 was issued on 2026-05-01, with a delivery date of 2026-05-14, on production line 2.

Standard budget for the order

From the table above, total standard direct materials for the order equals 30,910 SAR (for 100 chairs).

Direct labor:

• 1.5 labor hours per chair times 100 chairs equals 150 direct labor hours
• Standard hourly rate (including GOSI) equals 35 SAR
• Total direct labor equals 5,250 SAR

Manufacturing overhead (applied at 28 SAR per direct labor hour):

• 150 hours times 28 SAR equals 4,200 SAR

Total standard order cost equals 30,910 plus 5,250 plus 4,200 equals 40,360 SAR.

Standard cost per chair equals 40,360 divided by 100 equals 403.60 SAR.

Actual execution

When the order closes after 13 days:

• Quantities produced: 97 chairs accepted, 3 chairs rejected (within the 3% standard scrap, no scrap variance).
• Materials consumed actually: 31,400 SAR (unfavorable material variance of 490 SAR, a 1.6% overrun).
• Actual direct labor: 156 hours at 35 SAR equals 5,460 SAR (unfavorable labor variance of 210 SAR).
• Manufacturing overhead applied: 156 times 28 equals 4,368 SAR.

Total actual cost equals 31,400 plus 5,460 plus 4,368 equals 41,228 SAR.

Actual cost per chair equals 41,228 divided by 97 equals 424.99 SAR.

The gap between the standard cost (403.60 SAR) and the actual (425 SAR) is roughly 5%. This gap is analyzed in the closing report: what caused the material overrun? Did the wood price go up? Was a quantity lost in cutting? The answers determine whether the variance was situational or warrants updating the BOM or the standard purchase price.

Accounting entries

Material issue entry (May 1):

• Debit: Work in process MO-2026-00184: 31,400
• Credit: Raw materials inventory: 31,400

Labor and manufacturing overhead application (monthly):

• Debit: Work in process MO-2026-00184: 9,828
• Credit: Wages payable 5,460 and manufacturing overhead applied 4,368

Order closing entry (May 14):

• Debit: Finished goods inventory: 41,228
• Credit: Work in process MO-2026-00184: 41,228

After this entry, the WIP balance for the order equals zero, and finished goods inventory holds 97 chairs valued at 41,228 SAR (at 425 SAR per chair).

The most common mistakes in managing manufacturing orders

Before you use the template, watch out for the mistakes that repeat in most small and mid-sized Saudi factories:

• Not issuing a manufacturing order for small batches: the excuse is “it is not worth the hassle”, so their cost disappears into the larger orders and corrupts the real profitability report.
• An outdated BOM: using the list for two years without review, while the material price changed, the supplier changed, or the production technology improved.
• Not logging labor hours on the order: the factory settles for a total monthly wage without allocating it to orders, losing the ability to know each product’s profitability.
• Ignoring scrap: scrap is treated as “a natural part of the process” and not recorded, then appears as an unexplained variance every month.
• Mixing manufacturing orders with purchase orders: pulling from the warehouse without a material issue note that ties the material to a specific manufacturing order disrupts inventory.
• Allocating manufacturing overhead at a stale fixed rate: the rate was set once years ago, while the cost structure has shifted, making profitable orders look unprofitable.
• Not closing orders on time: an order stays open for months after actual production has ended, inflating the WIP balance on the balance sheet artificially.
• Relying on Excel for a multi-product factory: fine in the early days, but becomes a source of errors once active orders exceed 20 a month or product count exceeds 50.

Zakat, Tax and Customs Authority (ZATCA) requirements for factories

ZATCA treats factories as a sector with its own particularities. Compliance requirements go beyond e-invoicing to include full tracking of the inventory and cost cycle:

1. E-invoicing

The factory must issue electronic invoices compliant with Phase 2 of Fatoora (Integration). Every sale of finished goods must be issued through an electronically signed invoice sent to the Fatoora platform in real time. Implementation details are available in the guide on technical integration with the Fatoora platform (ZATCA).

2. VAT on inputs and outputs

The factory reclaims input VAT (15% on raw materials and services) and collects output VAT (15% on sales). The difference is what is paid to ZATCA. Any defect in recording invoices against manufacturing orders creates a gap between recoverable input VAT and collected output VAT, and may strip the factory of recovering VAT on materials whose use in taxable production is undocumented.

3. Inventory movement report

During a ZATCA audit, the factory is asked for a full movement report: opening balance, purchases, issuance to production, finished output, sales, closing balance. The gap between physical stocktake and book movement must be explained (natural scrap, damage, theft). The manufacturing order is the only tool that ties inventory movement to a reason for each material issuance. A factory without orders equals a stocktake without explanation.

4. Zakat calculation

Zakat in the industrial sector is calculated on a base that includes productive fixed assets, inventory, and retained earnings. The value of finished goods inventory is part of the base, and the value of WIP receives special treatment. The more carefully manufacturing orders are documented, the clearer the Zakat base calculation becomes and the less exposed it is to adjustment by the authority.

How Qoyod helps in managing manufacturing orders and inventory

Designing the manufacturing order on paper is easy. Turning it into an automated monthly cycle that links material movement to the WIP account, generates product profitability reports automatically, and feeds the electronic sales invoices into the ZATCA platform, is the real challenge. Qoyod’s accounting platform is built to cover this cycle end to end, which is why it is used by factories in furniture, food, packaging, and cosmetics.

What you gain practically when you run manufacturing orders inside Qoyod:

• A unified product catalog with BOM: define each product once, link it to its standard BOM, and the system uses that BOM for every new order without re-entry.
• Automated inventory movement: when a material issue note is created for a manufacturing order, materials are deducted from the warehouse and posted to WIP instantly, in a balanced entry.
• Actual cost tracking per order: materials, labor, and manufacturing overhead show up for each order, with a comparison to the standard cost and variance calculation.
• Automatic transfer to finished goods: when the order is closed, accepted quantities are posted into finished goods inventory at an accurate cost price.
• Integration with e-invoicing: every sale of finished goods generates an electronically signed invoice compliant with ZATCA requirements, linking the sale to a stock-out movement.
• Product profitability reports: the system displays the profit margin for each product based on actual data, not a separate estimate in Excel.

The biggest automation payoff shows up monthly. The factory’s accounting close that used to take a week (with manual stocktakes and multiple reconciliations) shrinks to a day or two, because inventory movements run in parallel with production, not after. For those starting a factory and wanting a correct accounting framework from day one, the article on managerial accounting and its tools in decision making is useful, as it links manufacturing orders to pricing decisions. To understand the full accounting cycle that manufacturing orders fit into, see the accounting cycle and its stages.

When to review running manufacturing orders

The minimum is a weekly review of active orders. Sit with production management and review:

• Orders behind the planned delivery date (why?).
• Orders that exceeded the material budget by more than 5%.
• Orders whose actual labor hours exceeded the standard by more than 10%.
• Orders closed this week: what is the average variance? Is there a pattern?

At the monthly level, all orders whose production has actually ended are closed even if they have not been delivered to the customer yet. Not closing them inflates the WIP balance on the balance sheet and gives a misleading picture. The factory’s monthly accounting close meets the requirements of closing the accounting period, which mandates closing temporary balances before preparing financial statements.

FAQs about manufacturing orders

Is a manufacturing order legally required in Saudi Arabia?

There is no direct regulation requiring a business to issue a “manufacturing order” in a specific format. But ZATCA requirements for tracking inventory movement, and Saudi accounting standards requirements for valuing WIP, make having a manufacturing order system a practical condition for any factory aiming for auditable financial statements.

What is the difference between a manufacturing order and a work order?

A manufacturing order is internal: to produce standard inventory for later sale. A work order is broader: to execute a service or a custom product for a specific customer, and may contain several internal manufacturing orders as execution stages.

Can I manage manufacturing orders in Excel?

In the beginning, yes, especially for factories issuing fewer than 10 orders a month and producing 3 to 5 products. As the factory grows, Excel becomes a source of errors: gaps between stocktake and books, delays in calculating actual cost, difficulty issuing profitability reports. An integrated accounting system becomes a necessity before the chaos costs you more than the system itself.

How do I calculate manufacturing overhead for a specific order?

You use an overhead rate calculated annually as total expected manufacturing overhead divided by total expected labor hours (or any other base you choose). Then you multiply it by actual labor hours on the order. At year-end, the gap between applied and actual overhead is settled.

What do I do with defective units?

If they are within the allowed standard scrap, their cost is charged to the order and spread across the good units. If they exceed the standard, they are moved to a “scrap variance” account and show up in the monthly variance report, with causes analyzed. Units that can be reworked are recorded as Rework and the rework cost is charged to them.

Does a manufacturing order enter the Zakat calculation?

The value of WIP and finished goods enters the factory’s Zakat base. The treatment details vary by activity, and it is recommended to review them with a licensed chartered accountant before filing the annual Zakat return.
