What investor-ready books actually mean for a UK seed-stage startup

A seed investor is not buying last year’s Companies House filing. They are trying to work out whether the cash, the revenue and the costs in front of them describe the company they think they are funding. “Investor-ready” is a practical standard for that conversation. It means the bank ties out, the cut-off is honest, and the founder can walk from a profit figure to the cash in the account without a new spreadsheet appearing overnight.

Statutory accounts still matter. A private limited company prepares annual accounts and files them with Companies House. The usual deadline for a private company is nine months after the end of the accounting period, with different rules for a company’s first accounts. The detail is on GOV.UK’s guide to preparing and filing annual accounts. That document is a legal output. It arrives too late, and in the wrong shape, to run a raise.

What “clean” means in the ledger

Start with the bank. Every account the company uses - current accounts, savings, payment providers, currency wallets - is reconciled to a statement date you can name. Unreconciled feed lines are not a close. They are a list of things you have not looked at.

Then the cut-off. Sales and costs sit in the month they belong to, not the month the invoice happened to be uploaded. Deferred income, accrued costs and prepayments are the unglamorous lines that stop a profit figure from being a cash figure in disguise. If you bill annually and recognise the whole invoice on day one, the profit and the cash will tell different stories, and diligence will ask which one you meant.

Debtors and creditors should be lists a person can read. A customer balance that is ninety days old needs a sentence: paid since, disputed, or doubtful. A supplier balance that does not match a contract needs the same. Intercompany balances, if you have more than one entity, need to agree on both sides. A group that cannot explain a balance sitting between two of its own companies is not ready for a data room, however healthy the trading company looks on its own.

The cap table is not a bookkeeping report, but investor-ready books point at it. Options, SAFEs or advance subscription agreements, and any SEIS or EIS shares already issued, should match what the lawyers and the register of members say. The books do not replace the legal record. They should not contradict it.

The pack, not the export

A useful pack for a UK seed-stage company is short:

• Profit and loss for the month and the year to date, with enough lines that revenue and the main costs are visible.
• A balance sheet that includes cash, debtors, creditors and any director or intercompany balances.
• A cash flow, or a clear bridge from profit to the movement in cash. If you only have an indirect bridge, say so.
• The definitions you are using for burn, runway and revenue. Write them on the page. The KPI note covers why those four get asked first.
• A one-paragraph commentary: what changed, and what you are doing about it.

That pack is management information. It is not a statutory format, and it does not have to look like FRS 102 disclosures. It does have to be the same numbers as the ledger. A model that does not tie to the last closed month is a story, not a set of books.

What diligence asks for in the first week

Financial diligence at seed is usually a shorter list than founders fear, and a stricter one than they hope. Expect requests for the ledger or a download, bank statements, the last management pack, aged debtors and creditors, the VAT position, payroll summaries, and any outstanding tax matters. Also expect the constitutional documents and the cap table from the lawyers. Your job is to produce the finance half without rebuilding it under pressure.

Two clocks run beside the raise and are easy to ignore until someone asks. Corporation tax is a Company Tax Return, normally due 12 months after the end of the accounting period, with payment for many companies due earlier - nine months and one day after the period ends. The rules are on GOV.UK: company tax returns and pay your Corporation Tax bill. VAT, if you are registered, follows its own return cycle: VAT returns. A company that is late on either will spend the first investor meeting explaining the filing, not the product.

The confirmation statement is separate again. It confirms the company’s details at least once every 12 months: file a confirmation statement. None of these filings is the investor pack. All of them are questions you would rather have answered before the data room opens.

What you can do before you hire anyone

Export the trial balance and reconcile the bank to a date you choose. List every balance-sheet account you cannot explain in one sentence. Decide, in writing, when you recognise revenue. Put director expenses and loans in the open, not in a miscellaneous code. If there are two companies, list what each owes the other.

That is not a finance function. It is the minimum so a finance partner, or you, can close a month without archaeology. Founder Finance at Finox is the monthly version of this: a close, cash and runway, a one-page KPI pack, and UK accounts, corporation tax and VAT prepared from the same ledger. It is a retainer, typically £750–1,250 a month. It is not a guarantee that an investor will fund you.

If the books are already tidy and you only need a partner for an owner-managed company, Growth at £500 a month is the smaller scope. If a board pack and a live round need the model kept in step, Raise & Scale starts from £1,500. The diagnostic is a written note on the ledger, the cash and how ready the numbers are. You keep it either way.
