Questions people ask

Is it really free for a small agency?

Yes. Invoices, payments, customers and full accounting are in the free core, with up to 5 users. You pay only for the modules you switch on.

Can I invoice clients abroad in euros?

Yes, with the Multi-Currency module (€9.99 a month), which keeps the exchange rate on every document.

Can my accountant access the books?

Yes. Your accountant gets their own login and works in the same books, so month end needs no exports.
