Why free

Because it already existed.

The calculators run on the same engines that produce the payslips and the VAT returns in our portal, and the PDF tools are the Invoice hub without the administration around it. If you only want a number or a PDF, that is fine — you do not have to become anything for it. If you do not want to do the rest yourself either, an English-speaking accountant starts at € 29 a month.
