What we do differently
An ordinary bookkeeping program gives you software, but the work is still yours. With us you get the VAT portal and a team that checks your work: you enter, the portal calculates, we check and file.
- Low fixed prices – you know in advance what you pay.
- 100% online – no office appointments, no paper.
- Real people – an answer within one working day.
- Help in your own language.
Our team
Our team consists of staff trained in bookkeeping and tax. Every return is checked by a person before it is filed with the Belastingdienst.
