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
- Open Aedon.Purchases, click the Purchase Orders tab and open the order.
- Check the lines. Anything you change after converting must be changed on the invoice.
- 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).

- Click the Purchase Invoice link to open the invoice. It is created as a Draft.
- Check it against the supplier’s invoice, add their invoice number as the Reference if needed, then click Post.
