Inventory and Purchasing Software Development

Define the units before importing the catalogue

Cases, packs and single items need explicit conversion rules. Variants need separate identities where price, barcode or quantity differs. We map those rules before importing stock.

The scope can include stock by branch, warehouse or bin, supplier references and reorder levels. Serial numbers, batches, expiry dates and measured quantities are planned around the actual goods.

Follow the order through physical receiving

A purchase order records a commitment. A goods receipt records what arrived. A supplier bill records the amount owed. We link them so a short shipment or changed price can be reviewed before payment.

Partial deliveries, damage and supplier returns retain their own histories. Transfers have a source and destination, with an agreed treatment for goods in transit.

Carry purchasing costs into valuation

A landed cost workflow allocates approved freight, duty and other acquisition costs using the chosen basis. Keep the supplier currency, conversion rate and supporting documents with the shipment. Recoverable tax and inventory cost have separate treatment.

In a worked example, 100 units costing 10 each and 200 in allocated acquisition costs have a total cost of 1,200, or 12 per unit. The example excludes recoverable tax and depends on the approved allocation policy.

Make stock differences explainable

A count captures its date, location, operator and reason for a difference. We define how sales and receipts during the count are handled. Restricted items can require a second approval.

Acceptance testing follows a small quantity through receipt, sale, return, transfer and count. The remaining quantity and ledger valuation must be reproducible from those events.
