Accounting — your books, without the jargon

The onboarding walkthrough for a business owner who is not an accountant: what an invoice, a bill, a receipt and a payment are, sending your first invoice and recording the money against it, letting a shipped order invoice itself, scanning a supplier bill and paying it, reconciling the bank, and the three questions the reports actually answer — plus, once, what your accountant will want and where it already is.
