Figure 4.5 — The Debit Note form. Drawing to be produced after the UI/UX pass: annotated capture of the debit note form naming a debit line, the invoice allocations, and the totals block.
The mirror of the credit note (§3.6): Code; Supplier, whose charge is being corrected; Date; Notes — the reason, written for the supplier and the auditor. Its lines carry Product, Description for non-product debits, Quantity, Unit Price, and computed Ext. Amount and VAT. Invoice Allocations name the purchase Invoice and the Amount applied to it — optional while drafting, effective on posting, reducing what that invoice is still owed; the remainder stands as credit with the supplier. Debit Note Totals — Subtotal, VAT, Debit Note Total — close the form.
