We use Breeze forms for registration for conferences or classes with tuition/book costs where the processing fee is necessary to be covered as it is not a giving transaction. Having to manually do the math and include processing fees on every form payment option is tedious. Additionally, considering that the processing fee for AMEX fees are higher than other cards, we can't manually set one price without eventually overcharging or undercharging someone depending on how they choose to pay. Furthermore, if you manually add a processing fee to the total price, for example adding $1.03 fee to a $25 charge would mean we charge $26.03 on the form. However now that we are charging $26.03, the processing fee actually jumps to $1.05 because it is charging the fee on the higher amount we manually put on the form. This is confusing and I would really like to see a solution that automatically adds the appropriate processing fee and perhaps boilerplate text explaining the fees so that these steps don't have to be done manually.
