Used this developers app for quite a few years until they repeatedly sent me a big email offering faster payments from my invoice by allowing them to handle payments through BPAY, they neglected to mention anywhere in the email or at any point during the registration process that it would cost me around 6% of every transaction, that was the end of the trust I had in them, got better things to concentrate on than the people I pay for a service trying to stick a finger in my bum, bookipi no.1
