WIP in Business Central: The 3 most expensive mistakes and how to avoid them
Unfinished products, inaccurately valued, distort the balance sheet, block liquidity – and often go unnoticed for a long time.
“Why is the WIP account suddenly in five figures?” The colleague from Accounting stares at the screen: 38,410 euros. Yesterday the account was still empty. “These are the current orders,” says the production manager. “We started today, we’ll continue tomorrow.” Everyday life for him – a problem for her: “Which orders exactly? And which of them are finished and which are not?”
Scenes like this occur when work in progress (WIP) is not valued correctly. WIP is more than just an accounting obligation. Only if work in progress (WIP) is recorded correctly
- the balance sheet reflects the actual company value,
- liquidity planning functions reliably,
- and production can be controlled in a targeted manner.
But why is WIP so difficult to grasp? And where are the biggest pitfalls?
What is WIP – and why is it important?
Work in progress are products in process – i.e. between raw material and finished product. They are not yet ready for sale, but already have a value: through the material used, working time and overheads.
This value belongs in the balance sheet. If it is not recorded or recorded incorrectly, there will be gaps in the figures, with consequences for planning, reporting and audits.
Example: An order for 100 machine parts is 60% complete. Material and working time have so far cost 24,000 euros. This value belongs in current assets under “work in progress”.
When is WIP relevant to the balance sheet?
According to HGB (Section 266 (2) B. I. 2) and IFRS (IAS 2), work in progress is included in current assets as soon as it has an economic value. The WIP value increases with each work step. Reliable figures can only be obtained if production, costing and accounting work closely together.
Who benefits from clean WIP?
Financial managers:
- have a reliable basis for the balance sheet and reporting,
- avoid hectic postings at the end of the month,
- pass audits with confidence.
Production management:
- sees the percentage of completion per order at all times,
- recognizes losses and bottlenecks at an early stage,
- calculates more precisely thanks to transparent WIP figures.
Management:
- manages on the basis of realistic figures,
- plans liquidity more reliably,
- recognizes capital commitment at an early stage.
The 3 most common mistakes with WIP in Business Central – and how to avoid them
1. WIP is not activated at all or is activated incorrectly
The “Activate production costs” function in Business Central must be set up correctly. Otherwise, WIP values will end up in the warehouse but not in financial accounting – with the risk of hidden stocks and serious valuation errors.
Tip: Configure WIP properly, with clear routines for stock and production postings. This is the only way to keep your financial figures precise and meaningful.
2. A collective account for everything
Material, wages, corrections and transfers often end up in one account. This makes evaluations difficult.
Better: Keep separate accounts, for example for revaluation, scrapping and completion. This allows you to track values and processes in a targeted manner.
Important: Always control postings via subledgers. Direct postings in the general ledger obscure the process.
3. Differences between general ledger and subledger
Business Central makes a strict distinction between inventory and financial accounting. If postings are not exactly reconciled, differences arise, often unnoticed, until the year-end closing.
Solution: Regular reconciliation reports between the general ledger and sub-ledger help to identify and rectify such discrepancies in good time.
A clear view of current assets: WIP is the key
Proper WIP recording has a direct impact – on the balance sheet, income statement and management. It shows:
- the real inventory value in current assets,
- inventory changes in the income statement,
- the current status of production – transparent for everyone involved.
If you ignore WIP, you risk unclear margins, chaotic month-end closings and stress during the audit.
