I am currently doing all my financial accounting through Wave but feel this is a very crude system. It doesn't take into account selling fees deducted by PayPal, Shopify and other platforms that I use. Is there an all in one accounts system that slots in with Shopify and takes all these fees into account. I use QuickBooks for my other business which is great but I am creating the invoices on that one and they are being paid through PayPal. With my online shop it is very different.
