What we run
A complete finance function, delivered quietly.
One engagement replaces the bookkeeper, the controller and the scramble before every deadline.
01
Bookkeeping
Daily categorisation, reconciliations and an audit-ready ledger maintained by a dedicated accountant.
02
Monthly close
A five-day close with P&L, balance sheet and cash flow delivered with commentary you can act on.
03
Back office
Payroll, AP/AR, invoicing and vendor management run quietly and correctly in the background.
04
Advisory
Budgets, runway models and tax-season readiness with a partner who knows your numbers cold.
The engagement
Three movements, then a rhythm you never think about.
Step 01
Diagnostic
We review your ledger, entity structure and reporting cadence, then map exactly what is missing.
Step 02
Rebuild
Historic clean-up, chart of accounts redesign and systems migration handled end to end.
Step 03
Run
A recurring rhythm of reconciliations, closes and reviews with one accountable point of contact.
“They took a four-year mess and handed back a clean set of books in six weeks. We closed our raise on the strength of that reporting.”
