In the same way that a floppy disc as the "Save" button is wildly outdated, so too does "bookkeeping" when applying to ecommerce companies. While companies of yore had legitimate paper trails, more and more businesses are completely digital, from their invoices to their accepted payments. An ecommerce accountant does everything a CPA would, but with your digital space, this means collecting, analyzing, and reporting the financial data of your business. Having a CPA specializing in ecommerce is invaluable especially where "shipping" of goods is concerned.
