Q. Can you please advise when a part payment is made on an invoice,  why only the first payment integrates back to Connectwise. Any other payments do not integrate back. Is there a setting that needs to be changed at all?

A. The invoice in ConnectWise shows a section for the received payments which looks like a grid, suggesting that you would be able to log multiple payments until fully paid, but actually it only accepts one payment, thus forcing you to overwrite the one payment in the grid over and over until fully paid.

Because ConnectWise works that way, then our integration is forced to also export every next payment into the same item in that grid. So we do export every next payment in reality,  It's just how ConnectWise presents it.
