Outsourcing and subcontracted bookkeeping for firms
We take on agreed bookkeeping and payroll scopes when your firm needs extra capacity — without blurring roles toward your end clients and without providing tax advisory services.

B2B collaboration details
Who this is for
Accounting firms that need a reliable subcontractor for ledgers, registers and payroll — during seasonal peaks, staff leave or portfolio growth without immediate hiring.
What we can take on
- Full ledgers for companies and simplified books within an agreed model
- HR and payroll: payslips, social security filings, operational HR paperwork
- Book reconstruction when you onboard new mandates
- Overflow capacity while you keep the client relationship
End-client scopes are also described under full accounting and HR & payroll — for B2B we set separate SLAs and communication channels.
How B2B collaboration works
Clear scope, document cut-offs, file formats and named contacts on both sides. Your end client stays yours — we are the operational back office.
What is out of scope
We do not provide tax advisory services or representation in disputes. Interpretations and tax strategy remain with you or your advisers.
