§ The team
One named lead on your account.
Every client has one named lead from the team, and the same person runs the monthly call. Nobody hands your books to a junior you have never met.
We keep the client list small on purpose, so the people who scope the work in the first call stay on it afterwards.
§ What you get
Your finance function, every month.
Five pieces of work behind the retainer, and an example of the pack you receive.
- 01Monthly close. Profit and loss, balance sheet and cash flow, with the bank reconciliation done and a pack a founder can read.
- 02Cash, burn and runway. The view you use between raises, updated every month.
- 03Investor KPI pack. One page covering the numbers a board or a seed investor will ask for.
- 04Monthly close call. With your lead, so the commentary is yours before anyone else sees it.
- 05UK accounts, corporation tax and VAT. Prepared from the same ledger. Year-end accounts and the corporation tax return are included in the fee.
§ Fit
Who Founder Finance is for.
It suits companies that need the numbers every month, not only at year end.
A good fit
Founder-led UK companies
- Pre-seed to Series A
- More than one entity, or overseas payments that make the ledger messy
- You have Xero or a bookkeeper, and nobody owns the numbers
- You are raising, or you expect diligence in the next 6–12 months
Not the right fit
A different job
- Filing-only work with no monthly reporting
- Contractor-only packages
- A company that wants a full-time CFO in the office every day
- Statutory audit (we refer you to an audit firm)
§ Pricing
Three retainers, one for each stage.
Founder Finance is the startup retainer. Growth is the step down. Raise & Scale is the step up when a board pack and a live round need more time.

§ Questions
Common questions.
What is Founder Finance?
Founder Finance is Finox’s monthly finance-partner service for UK startups: investor-ready books, a KPI pack and management reporting, typically £750–1,250 a month. A named lead from the team owns the account.
What do I actually get each month?
Each month you get a close (profit and loss, balance sheet and cash flow), a cash, burn and runway view, a one-page investor KPI pack, and a call with your lead. UK accounts, corporation tax and VAT are prepared from that same ledger.
Who is it for?
It is for founder-led UK limited companies that have outgrown bookkeeping and are not ready to hire a full-time CFO. That is usually pre-seed to Series A, including teams getting ready for diligence.
How does the price compare with Growth and Raise & Scale?
Growth is £500 a month for an owner-managed company that needs a finance partner rather than a raise pack. Raise & Scale starts from £1,500 a month when you also need a board pack, model upkeep and diligence support. Founder Finance sits between them at £750–1,250.
How do we start?
Book a 30-minute diagnostic call. After that, a 7-day diagnostic is a written note on your ledger, cash and investor readiness, and you keep it whether or not you hire Finox. A limited number of diagnostics are free each month; otherwise the note is £750, credited to the retainer if you start.
Are year-end accounts and corporation tax extra?
No. While you are on a retainer, year-end statutory accounts, the corporation tax return and the confirmation statement are prepared as part of the monthly fee. One-off projects, such as an investor model or an R&D claim, are priced separately and agreed before we start.
Do you use software or AI on my books?
Yes, for the first pass: bank feeds, categorisation, reconciliation matching and a first draft of the commentary. A person from the team reviews everything before it reaches you, an investor or HMRC. Your data is not used to train third-party AI models.
Who supervises Finox?
HMRC supervises Finox for anti-money-laundering, and Finox is an HMRC-registered tax agent for corporation tax, VAT, PAYE and Self Assessment. Finox is also registered with the ICO for data protection. We prepare accounts and tax filings; we do not guarantee a relief, a refund or an HMRC outcome.
