Supplier invoice: fields & CSV layout
Supplier invoices vary wildly in layout but carry the same core fields. For AP automation you need them normalized. Here are the fields a supplier invoice contains and the CSV layout that feeds a bills import.

Conversion notes
›invoice_number + vendor is the dedupe key — keep both so you never pay the same invoice twice.
›due_date drives your payment run; capture it even when it's only implied by terms ('Net 30').
›Keep tax separate from subtotal for correct VAT/GST reclaim and for accurate expense vs tax posting.
FAQ
Line items or header-only?
Both are available; AP teams often post header-level and only itemize for inventory or job costing.
Feed into QuickBooks/Xero?
Map vendor, date, invoice_number and total to your bills-import format; a CSV-to-bills importer handles the rest.
