Most of our purchase orders are prepaid either fully or with an initial deposit and subsequent balance payment before goods arrive.

Currently we just input the payment in the supplier account which then shows a credit balance but there is no link to what the payment is for and no link to the Purchase order to see what has been paid against that PO.

It would be really helpful if there was a way to record a payment against the actual PO so that at any given time it would be possible to extract from Sage the outstanding due unpaid amount on unposted Purchase Orders. If it could be linked to the payment in the supplier account, it would only need to be entered once.
