FAQ

Questions founders ask us first.

Are you UK-regulated? Who actually does the work?
As a UK firm we hold full HMRC agent status and follow recognised UK professional standards. Every client has a named bookkeeper, a qualified accounting manager and (on Growth & Scale) a fractional CFO. No anonymous offshore back office.
Can you take over from my current accountant?
Yes — and we do this most weeks. We handle the professional clearance letter, request the handover pack, and migrate you with zero gaps in filings. Most switches complete in 10 working days.
What accounting software do you use?
We're a Xero-first practice and most clients run on Xero with Dext for receipts. We also support QuickBooks Online, FreeAgent, and can integrate with Stripe, GoCardless, Pleo, Brex equivalents, HubSpot and most stacks. You keep your tools — we plug in.
How is this different from a fractional CFO platform?
CFO platforms send you advisory hours. We do the actual books, payroll and tax filings as well — so the CFO advice is grounded in numbers we own, not numbers we've inherited. One team, one accountability.
Do you work outside London?
We're UK-wide. Most of our clients are in London and the Home Counties, but we have founders in Manchester, Bristol, Edinburgh and remote teams across the country. Everything we do is cloud-native, and we also have our own team based in South Africa. For clients with operations in the US, Germany, France or the Netherlands we work with a trusted network of partner firms — useful when you're expanding internationally and want one point of contact who knows the business.
How fast can you start?
After a 30-minute discovery call we send a fixed-fee proposal within 48 hours. Once signed, we're typically running your books inside two weeks — often less for newly-formed companies.
