A stock register, on paper or in a spreadsheet, is how most businesses start. Inventory software does the same job differently: stock is updated by the documents that move goods, instead of by a separate entry in a register.
Side by side
| Manual register | Inventory software | |
|---|---|---|
| Recording movements | A separate entry after each movement | Updated by the purchase, challan, invoice or transfer itself |
| Several godowns | One register per godown, added up by hand | Stock by store, with transfers between them |
| Batches and serials | Extra columns or separate lists | Recorded on the item and its documents |
| Stock value | Worked out separately | Calculated from recorded cost |
| Reordering | Someone has to notice | Items below a set minimum are listed |
| Cost and effort | Low cost, high discipline | Software cost, less re-entry |
When a manual register is enough
One location, a short item list and one person responsible for stock: a well-kept register can work. It becomes hard when goods move between places, several people handle stock, or you need batch or serial detail.
What software does not fix
Software only knows about movements someone records. Unrecorded transfers, returns put back without a document and breakage still cause discrepancies, so regular counts are needed either way.
Common questions
How does inventory management software work?
Each document that moves goods, such as a purchase, a delivery, a return or a transfer, updates the stock of that item in that store when it is saved. Stock on hand, its value and the items below their minimum are then read from those movements rather than kept in a separate register.
