How to link a Purchase Order to a Bill?

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 required Bill page in Appcrual and choose a Purchase Order on your right (a dropdown under 'Purchase Order Link' title).

In order for a Purchase Order to appear in this dropdown it must match Contact and/or Project settings of the Bill and be marked with 'sent' status.

Once linked - Purchase Order will reflect changes with related paid and unpaid amounts.
