When a Method of Payment with a Surcharge is selected for an invoice payment you have two options:
1) You can proceed with the default payment amount which will be calculated as the original amount due plus the surcharge amount:
2) You can manually enter a specific payment amount Eg. $500:
In this case the surcharge is treated as part of the “Amount Received” (total amount collected from the customer).
For instance, when you enter $500 as Amount Collected for a MOP with a 3% Surcharge, DX1 calculates that as a $500 payment INCLUDING a 3% surcharge (= $14.56), based on $500 being the total amount paid by the customer.
The calculation is NOT based on taking the total payment amount and multiplying it by 3%, which would be a surcharge of $15, making the TOTAL Amount Collected from the customer $515.
In this example with a $500 payment and a 3% surcharge, we collect the surcharge amount of $14.56 because the ACTUAL deposit amount being applied to the invoice is 500.00-14.56 = 485.44, based on $500 Amount Collected including the 3% surcharge.
Working through the math, and putting on an algebra hat, the calculation for the amount being applied to the invoice would look like this:
