Has anyone found a solution to do partial billing based on amount rather than quantity? When we partially bill a PO with line item amount of 50k and qty 1, only bill them for 7024.75, we have to do a (simple - but annoying) calculation to get the exact qty - 0.140495 in this case to plug into the Bill. Any recommendations here?

Are these for services? We just swap the quantity and rate. We put 50k in the quantity and 1 in the rate in the PO to handle partial receipts and billings later on

Not a bad idea - I will do some testing around using this method. Thank you for the idea @Luis!!
