# Accounting for a Factory or Workshop: How It Differs *A shop sells what it bought; a factory sells what it made — and that difference turns costing and inventory upside down* > **In short:** What distinguishes accounting systems for factories and workshops: three inventory levels, job costing, waste measurement, and where general systems stop. - **URL:** https://www.snad.io/en/blog/nizam-muhasabi-masnaa-warsha-saudi - **Arabic original:** https://www.snad.io/blog/nizam-muhasabi-masnaa-warsha-saudi - **Category:** Industry — Workshops & Light Manufacturing - **Tags:** Manufacturing, Workshops, Inventory Management, Cost Accounting, Snad - **Published:** 2026-08-13 - **Updated:** 2026-08-13 - **Publisher:** Snad (snad.io) A retail shop buys an item and sells it unchanged, so the cost of what it sold is known directly from the supplier invoice. A factory or workshop buys **materials** and sells a **product** that did not exist before. Between the two sits a transformation consuming materials, time and energy — all of which must enter the cost, or you are pricing by guesswork. This article sets out the four differences, then says plainly where general systems stop. ## The core difference: from buying to transforming In retail the cost equation is one line: purchase price plus freight. In manufacturing the finished product carries: - **Raw materials** with their quantities and shifting prices - **Consumables** used up without appearing in the product (adhesive, abrasive, thread) - **Direct labour** — the hours of whoever makes it - **Indirect costs** — electricity, machine depreciation, workshop rent The best-known error in small workshops: counting **raw materials alone** as the cost, then adding a margin on top. The result is a price that looks profitable while it merely covers materials and quietly eats into everything else. Hence the rule: whoever does not know the product's cost does not know whether they profit — only that cash is coming in. ## Three inventory levels, not one A shop has one level: finished goods. A factory has three, and each carries a value that belongs on the balance sheet: **1. Raw materials** — bought and not yet in production **2. Work in progress** — in production and not yet complete **3. Finished goods** — ready to sell The second level is the one most workshops omit, and it explains many questions: where did the timber we bought last month go? Usually the answer is that half of it sits as half-finished pieces on the floor, with its value in no ledger. The practical consequence: **a balance sheet understating assets**, and a profit report loading one month with the costs of products that will sell in another. This is not fixed by a more careful stocktake but by a system that knows all three states and moves value between them. ## Job costing — the question that sets the price The question any manufacturing system must answer: **what did this particular job cost me?** Not the monthly average, nor an estimate from experience — this job specifically: the table made for that customer, or batch number so-and-so of the shirt. Why it matters: pricing in workshops is usually built on **the last price I sold at** or on the owner's estimate. Both drift as material prices move. Someone buying timber at a price that rose 18 percent and selling at the old price loses money while believing they are keeping a customer. What you practically need: - **A recipe for each product** (a bill of materials with quantities) - **Consumption linked to the job**, not to the month - **Cost updated automatically** when a material's purchase price changes The first alone — defining the product recipe — solves half the problem, because it turns pricing from memory into calculation. ## Waste: a number that must be measured In manufacturing waste is not an exception but part of the process: offcuts, defective pieces, materials spoiled in storage, and rework. The problem is that none of it **passes through any invoice**. Stock falls and sales do not rise, so the gap appears at stocktake as a shortfall, usually and unfairly blamed on theft. What the system must provide: **a separate movement called waste or damage**, recorded at the moment it happens. Then waste becomes a figure in a report rather than a puzzle at stocktake, and you can ask the right question: is our rate normal for the industry, or is something wrong in operations or training? A measured waste rate is a pricing tool too: someone who knows they lose 7 percent of their timber builds that into the cost rather than discovering it at year end. ## What Snad covers in a factory or workshop Snad is a business management system that handles the material and financial side of a workshop or small factory: - Material inventory with its movements, receipts and transfers between warehouses - Damage and returns as separate movements appearing in reports - Purchasing, supplier payables, and a reorder alert that becomes a purchase order - Invoicing, accounting, automatic entries and payroll - Per-item movement reports and dead stock In practice, in a small workshop: run materials, purchasing, invoicing and accounting in the system, and enter the finished product as an item when it is complete — so its cost and margin come out of the same books, with no side file and no second subscription. ## Frequently asked questions ### How does accounting for a shop differ from a factory? A shop sells what it bought, so its cost comes straight from the supplier invoice. A factory transforms materials into a product, so it needs a recipe per product, three inventory levels (raw, work in progress, finished), and waste measurement. ### What is the commonest pricing error in workshops? Counting raw materials alone as the cost, then adding a margin. The result is a price that covers materials while quietly eating into labour, electricity and depreciation. True cost includes consumables, direct labour and indirect costs. ### Does Snad track production stages and work orders? No. Snad is a business management system, not a production planning one: it does not schedule production lines, track work in progress as a distinct state, or handle batch numbers. It handles materials, purchasing, invoicing, accounting, inventory and payroll. ### How do I measure waste in my workshop? By recording damage and offcuts as a separate movement at the moment they occur rather than waiting for a stocktake. The rate then becomes a figure in a report you can build into your pricing, instead of an unexplained shortfall blamed on theft. --- ## About the publisher **Snad (سند)** — a private Saudi software company based in Riyadh, founded 2025.
