Figure 4.4 — The Purchase Invoice form. Drawing to be produced after the UI/UX pass: annotated capture of the purchase invoice form naming the supplier's own invoice number, the goods-receipts picker, a matched line, and the totals block.
- Code — your number for the invoice (PI-…). Supplier Invoice No. sits beside it: the supplier's own number, the reference you will quote back to them in every query. Keep both; they answer different questions.
- Supplier — who sent it; sets the currency and rate as usual.
- Goods Receipts — [Standard] the matching heart of the form: pick the receipts this invoice covers and their lines arrive, each quietly keeping its link to the receipt line it came from — the link that clears GRNI, keeps open quantities true, and lets the module show its three-way match.
- Date and Due Date — the invoice's date, and when payment falls due, proposed from the supplier's terms.
- Currency and Exchange rate — the invoice's own money. Where its rate differs from a receipt's frozen rate, the difference is not hidden: it surfaces at matching as an exchange difference (§4.5).
- Branch and Department — where tracked.
- Narrative — the invoice's own note.
The Invoice Lines mirror Sales': Product, Quantity, Unit Price, computed Ext. Amount and VAT. Invoice Totals — Subtotal, VAT, Invoice Total — are what you now owe. In [Simple] the lines are typed directly and posting brings the stock in as well as recording the debt.
