What a generator cannot do
A free generator is right for an occasional invoice. It does not remember your last number, so the sequence can break; it cannot see who has paid; and it does not chase anybody. A gap or a duplicate in your invoice numbers is the first thing an auditor looks for.
What Bookkeeping & Invoicing adds
Bookkeeping & Invoicing numbers every invoice without gaps and locks it once issued, turns an accepted quote into the invoice, keeps statements with 30/60/90-day ageing, and from the Intermediate plan sends payment reminders on its own. It starts at R190 a month with no setup fee, and you can try it free for 7 days and 20 quotes or invoices, no card.
