A positive closing stock balance can hide an earlier shortage.
Was enough stock present at every point in the work sequence?
Use the matching calculator
Use this decision sequence
- Enter opening compatible stock and movements in chronological order.
- Record receipts and issues for each movement rather than only net project totals.
- Read the minimum running balance to identify the earlier missing quantity.
- Keep that timing shortfall separate from the final stock balance.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| Closing balance | The final cumulative quantity. |
| Minimum running balance | Reveals earlier unmet issues. |
| Same-entry receipt | Occurs before that entry’s issue in this stated model. |
Worked comparison
Starting with an illustrative two units, issuing four creates a two-unit shortage. Later receiving five and issuing two produces a closing balance of one. The final positive unit does not erase the earlier shortage. The ledger therefore reports one closing unit and two additional opening units needed to avoid the negative point in this entered sequence.
Check before using the estimate
Movements must be ordered and use compatible units; no warehouse record accuracy is assumed by the calculator.
All dimensions, product properties, prices and specifications in this example are illustrative arithmetic inputs. Use the values from your measured plan, selected product data sheet and supplier quote. This guide does not choose construction specifications or certify safety.
