CASH BACK FEATURE
It'll be great to have a cash back feature integrated into Fresha. For instance, Your Client pays with cash, but later needs back cash and opted to pay with card instead. There's currently no way to edit the invoice and change payment from "Cash" to Card. At the moment, the only option seem to be to void the invoice and recreate it, when you can just edit it and select other mode of Payment.
