Its main uses include: - Receiving goods from suppliers before completing payment procedures - Recording goods received on consignment or for inspection - Tracking inventory movements without immediate invoicing - Updating stock levels in the warehouse system ## Purchase Invoice A Purchase Invoice is a formal financial document that records the purchase transaction and creates a financial obligation. Its characteristics include: - Creates an account payable to the supplier - Includes pricing and payment terms - Used for accounting records and financial reporting - Subject to VAT calculations and tax compliance - Links directly to the general ledger ## Key Differences | Aspect | Inventory Supply | Purchase Invoice | |--------|------------------|------------------| | **Financial Impact** | No immediate financial impact | Creates account payable | | **Timing** | Can be recorded before invoice receipt | Recorded when invoice is received | | **VAT** | Not calculated | Subject to VAT calculation | | **Accounting Entry** | Inventory debit only | Inventory debit, Payables credit | | **Payment** | Linked to separate purchase invoice | Directly related to payment | | **Use Case** | Receipt, inspection, consignment | Formal purchase transactions | ## When to Use Each **Use Inventory Supply when:** - Goods arrive before the invoice - You need to inspect goods before accepting - Goods are received on a trial basis - You want to track receipt separately from billing **Use Purchase Invoice when:** - You have the complete purchase documentation - You need to record the financial obligation immediately - You require VAT compliance tracking - The transaction is finalized and ready for payment
