How can I accept credit card/bank payments instantly on the phone (for my remote services) with customers and then send them a sales receipt, as opposed to an invoice?

Hi @ela4,

Thanks for the question!  It sounds like our GoPayment app would be a good solution for you.  Here's an article that will walk you through how to process payments on the GoPayment app and how to send your customers a receipt:
