Stock should be produced by real events
A product balance rises when goods arrive, falls when they are sold or adjusted, and moves through a transfer. Keeping those reasons means a wrong-looking number can be investigated. Replacing the balance alone hides the event that caused it.
Writing sales during the day and reducing stock at closing creates duplicate work. Cancellations, returns and missed lines make the final adjustment unreliable.
Goods, cash and debt follow different clocks
A customer may take an item now and pay next Friday. A supplier may deliver today and be paid at the end of the month. The records therefore have separate purposes:
- sale: products provided to the customer;
- customer receipt: money received;
- purchase: merchandise delivered by the supplier;
- supplier payment: money paid out;
- expense: a cost that does not necessarily create stock.
The model explains why sales can increase without the same cash movement, and why stock can rise while a supplier balance remains outstanding.
Introduce the workflow with fast-moving items
Set up the items staff handle most, with correct unit, cost, selling price and stock location. Enter opening stock once. After that, use actual sales, purchases and transfers as the normal source of change. Adjustments should explain exceptions rather than become the daily method.
Compare a physical sample with the report each week. Review cancellations, part-payments and unusual movements while people can still remember the circumstances.
Keep the scope honest
This approach suits independent shops, resellers, small wholesalers, market traders and service firms tracking parts. Businesses requiring production recipes, ecommerce fulfilment, colour/size matrices, batches or regulated till functionality should assess specialised products.
