How we work
Careful
Every month is reconciled. Anything that does not fit is clarified before it reaches the tax advisor.
Open
Prices are on the website. We say clearly what we may do and what the tax advisor does.
Digital
Receipts, reports and contracts run through the client portal. Paper is the exception.
Available
Fixed contacts, in Hamburg also in person at your premises.

Our team
Monthly bookkeeping is the responsibility of bookkeepers with commercial training and many years of practice in DATEV.
Placeholder: names, photos and qualifications of the team will be added before launch.
Working together through the client portal
Sign contracts, upload receipts and download reports: everything in one place, in English or German. We collect our questions there instead of asking receipt by receipt by e-mail.
