This seems to me like an attempt to get into the small end of SME space and also those simpler cases where there is a) No stock involved b) A small number of expenses (like items on a credit card) I guess a saas startup or a freelancer tend to be relatively naive to finance so generally hire an accountant. This is not just to do their books of course, in the UK they are looking for someone to advise on structure, and this often means forming a corporation, which they will do for you. Then there is the issue of VAT (sales tax) which people don't find easy and are scared of. The accountant will do all of this for you for a fee. To save you money they might suggest that you post your expenses to some kind of portal based on xero or quickbooks. Typing in the few expenses of these kind of businesses is absolutely the most trivial of thing to any bookkeeper. They might also use this system to raise invoices from if they are a free lancer. In a small Saas business the sales are most likely automated, the Stripe charges are a one liner, and the expenses are often all on a credit card (hosting etc). Payroll is a doddle if you are on fixed salaries and a complete PITA if variable hours no matter what the accounting system. If I was to do the monthly bookkeeping for one of these businesses I would spend more time opening the files and administering my billing to them than I would doing the books. My point here is you either a) know what you are doing and could use a spreadsheet or intuit or xero or Sage or b) need an accountant for advice beyond 'what code do I post hosting costs to'. Maybe this fills a particular niche in the US, but I don't see it troubling the accounts world in general. I work in a different space. We have stock, and an ERP keeping count of sales, cos etc. This is the space your Oracle, Sage, SAP are operating in with big money implementations, and i don't see anything to trouble that here.
