Can there be a way where we can input what the cap is on our contractor commission so that we don't overcharge on big invoices. Currently we have to keep a log of all big payments over the cap and then refund contractors any overpayment.

If the system could stop the overpayment this would save us having to constantly refund on bigger jobs, it would help contractors because the often get confused with being over charged and then having refunds made to them so having to explain this to them also takes more time.
