I was wondering if there is a way to add a custom payment method. Right now Cash, Bank, Cheque, Credit Card, Paypal and Other exist. Where I live we have Mobile Payments, so I wanted to add that in. Is it possible and where?
It isn't currently possible to add your own payment methods to Wave. You'll have to go with Other, or Bank, depending on what makes the most sense depending on how those mobile payments work exactly.
Payment method only really appears on the expanded invoice page, after a payment was recorded. Do you tend to keep close track of the type payments you receive? I'd love to know more about the kind of insights you get out of that data.
