Taxes are calculated line by line and rounding is unit-tested, so the totals on your invoices match your orders to the cent. Invoice and credit note numbers are sequential and gapless, the way accountants expect. Once issued, a document never changes.
Invoice Inn starts from your store. It reads your colours and fonts and designs an invoice that looks like your brand. Keep it, switch to another template, or change any field, column and label yourself with a live preview. No code. Setup is your company and VAT details and a few clicks.
