There are tech savvy accountants, and/or small business/startup savvy accountants. We tried handling it ourselves but that was a terrible plan: we didn't know about every little business tax we should have been paying, the whole double entry stuff and when you recognize money versus when you actually get it is totally bizarre to me. We now engage a small accounting firm focused on small businesses, who handle our bookkeeping, cash flow analysis, invoicing, taxes, CFO duties, paying the bills, etc... It's great!
