What FairInvoice does
- Accurate to the cent. Taxes are calculated line by line and the rounding is unit-tested, so the totals on your invoices match your orders exactly.
- Sent without you touching it. When an order is paid, the invoice PDF is emailed to your customer automatically. Refunds get a proper credit note.
- Built for your accountant. Invoice and credit note numbers are sequential and gapless, a document never changes once issued, and any date range exports as a single ZIP.
- One flat price. Unlimited orders, every feature included — no per-order fees and no feature gates.
Who makes it
Fairwren is a small independent shop. The same person writes the code and answers the support email, which is the point: you are not filing a ticket into a queue.
