I am building out a custom POS app for a tool rental company. I would like to be able to accept cash payments for retail items and rental fees, but have the security deposit charged to a card that’s put on file.
I’m having an issue with the payments API where I can accept the cash transaction correctly, but it will only accept it if the amount is the same as the order total. Is there not a way to accept a partial payment via cash and then charge the remaining balance on the order to a card? I haven’t been able to find anything on split payments other than the square gift cards?
For example a sample order would be:
Order Total: $97.58
The portion of the order that can be payable in cash is $47.58. The security deposit needs to be paid through a card, which is kept on file in case of late fees. And is dipped through the terminal.
Is it not possible to accept a $47.58 partial cash payment on a $97.58 order?
