Converting a Purchase Order into a Purchase Invoice

Updated 31 October 2026

When the supplier’s invoice arrives for an order, convert the order into a Purchase Invoice. The supplier, dates and lines are copied across, so you only need to check them against the supplier’s invoice.

Convert a Purchase Order

  1. Open Aedon.Purchases, click the Purchase Orders tab and open the order.
  2. Check the lines. Anything you change after converting must be changed on the invoice.
  3. Click Convert to Purchase Invoice(1).

Once converted, the order’s Posting Status shows Converted to Invoice and the Purchase Invoice field links to the new invoice(1).
