We also use Approval Max as an add on to Xero where you create Purchase Orders for approval and it automatically feeds into Xero once approved.
We have recently received an email listing new features to add on to Approval Max which includes PO to bill matching, showing what has been billed and what is still outstanding. This should solve the problem but it is at an extra expense rather than being part of Xero as standard, which I think it should be.
We will be adding this to our subscription in the next month, when we have investigated further.
