What it is

Small-business invoicing and bookkeeping with a free core. You raise invoices, chase them, categorise income and expenses, and export the result at year end.

Best for

The independent coach who has outgrown a notes app but does not need real accounting software, and who wants invoices that look like a business sent them.

Watch out for

Card payments carry the usual per-transaction fee — free invoicing is not free money movement. Feature availability varies by country, so confirm your region is supported before you build a process on it.
