When Appcrual syncs your bills - it shows a complete reflection of the bills you have in FreeAgent.
To link a Bill to a Purchase Order you'll need to open the required Bill page in Appcrual and choose a Purchase Order on your right (a dropdown under 'Purchase Order Link' title).
Only purchase orders matching the following criteria will be shown:
- PO must be marked as "sent"
- PO's contact must be the same as the bill's.
- PO's project must be the same as the bill's, or PO must not have a linked project.
- PO's remaining total value must be greater than 0.
- PO's currency must match the bill's currency.
Once linked - Purchase Order will reflect changes with related paid and unpaid amounts.
