Actually advance playment should be clear within 7 days
I agree with you about this point.
We try to ask to vendor, but we could not change vendor for this time because it was for renew license.
But my concern was management unit. Could you answer it?
Whether do you manage "Advance Payment" by a "Person" unit or "Document" unit?
If it is by Person unit, we cannot continue to work anymore after we get error case. (Need to wait that vendor's response.)
Also, we cannot pay to 2 vendors by advance payment in the same time.
