Materials Accounting in Manufacturing
Materials are the biggest cost item in production, yet raw material accounting is done «by eye»? It’s unclear how much is really left in stock, a shortage is discovered when production has already stopped, and material overspend goes unnoticed. Buy too much — freeze cash; don’t buy in time — halt the shop floor.
Materials accounting in manufacturing is the control of raw material movement from receipt into stock to write-off into production. ERPJS materials accounting software shows real balances at any moment, calculates requirements for orders and writes off materials by the norms automatically. Below — how it works.
What is materials accounting in manufacturing?
Materials accounting in manufacturing is the recording of all raw materials, components and semi-finished goods: how much was received, how much is in stock, how much was written off into making products. Unlike plain inventory accounting, here write-offs are tied to production orders and the usage norms from the tech card.
Proper materials accounting answers three questions: are there enough raw materials for the plan, how much actually went into a batch, and was there overspend against the norm. Without it, production either stalls from shortages or freezes cash in excess stock.
What does materials accounting software give you?
Materials accounting software closes the whole cycle of raw material movement:
Raw material receipt
Receiving materials from a supplier with price, warehouse and responsible person. Balances update immediately.
Real-time balances
The actual quantity of each material in stock — with no spreadsheet reconciliation at month-end.
Write-off to production
Raw material is written off against a production order per the tech card norms. You see how much went into each batch.
Requirements and shortages
The system calculates how much material is needed for current orders and what's missing to purchase.
How is the material requirement for a plan calculated?
The raw material requirement is calculated automatically: the system takes usage norms from the tech card, multiplies by the quantity in production orders and compares with actual stock balances. The output is a list of what and how much to buy to fulfil the plan without stoppages.
This avoids two extremes: shortages, when production stops mid-order, and overstocking, when cash is frozen in excess raw materials. Usage norms are set in the tech card — how to build one is described on the Production Tech Cards page.
How does materials accounting work in ERPJS?
In ERPJS raw material accounting is connected to stock, tech cards and production orders in a single flow:
- Receipt. Raw material is received into stock at the purchase price — the actual cost of the material is formed.
- Storage. Balances are visible in real time, and you can keep several raw material warehouses (main, workshop, section).
- Write-off. When a production order is launched, materials are written off automatically per the tech card norms — the movement of each unit is recorded.
Materials accounting is part of a single production cycle together with production accounting and cost calculation. A general overview is on the ERP for Manufacturing page.
ERPJS materials accounting software shows real raw material balances at any moment, calculates requirements for orders and writes off materials by the norms automatically. No shortages mid-production and no cash frozen in excess stock.
Why is it better than materials accounting in Excel?
In Excel raw material balances almost always drift from reality: write-offs are entered late or forgotten, and shortages are noticed too late. There’s no link to production orders, so requirements for a plan can only be calculated by hand.
In software, balances update automatically with every movement, write-offs are tied to orders and norms, and requirements are calculated in one click. How to put inventory accounting in order overall — in the article Production accounting: how to automate from raw materials to finished goods.
Which manufacturers is it for?
Materials accounting is needed by any manufacturer where raw material is a significant part of costs:
- Furniture and woodworking
- Garment and textile
- Food and confectionery
- Metalworking and assembly
- Advertising production and printing
- Windows, doors and structures
Frequently asked questions
What is materials accounting in manufacturing?
It’s the control of the movement of raw materials, components and semi-finished goods from receipt into stock to write-off into production. The accounting shows real balances, requirements for orders and the actual consumption per batch.
How does the software calculate raw material requirements?
The system takes usage norms from the tech card, multiplies by the quantity in production orders and compares with stock balances. The output is a list of what and how much to buy to fulfil the plan.
How are materials written off to production?
Automatically when a production order is launched — per the tech card norms. Stock balances decrease immediately, and the movement of each material is recorded for control and cost calculation.
Can you keep several raw material warehouses?
Yes. The number of warehouses is unlimited — main warehouse, workshop, separate section. Movement between them is documented, and balances are visible per warehouse.
Is material overspend visible?
Yes. Actual write-offs are compared with tech card norms, so raw material overspend against the norm becomes visible. This helps find losses and look into their causes.
