Messy books are common; hidden liabilities are the real risk

Early companies often have informal accounting. Diligence separates harmless untidiness from problems that matter: unpaid taxes, related-party transactions, commingled spending and unrecorded obligations.

The point

I am rarely worried by a founder who says the books are a bit of a mess. I am worried by one who says everything is fine and cannot show a reconciliation to the bank. Untidiness is a stage of company life; an unexplained gap between the accounts and the cash is a different kind of problem.

What is it?

Most early companies do not have audited accounts, and many keep simple books. That is normal. Diligence looks for problems that are not.

Usually manageable Needs investigation Cash-basis bookkeeping unpaid payroll or sales taxes Late month-end closes founders' personal spending through the company Simple spreadsheets transactions with founders' other businesses No formal budget revenue recorded on invoice before delivery loans or advances not in the accounts grants with repayment conditions

A practical sequence:

  • Reconcile the accounts to bank statements
  • Check tax filings and payments are up to date
  • List every transaction with founders, relatives or related companies
  • Ask directly about loans, guarantees and commitments not in the accounts
  • Put answers in writing through representations or a disclosure schedule
  • Why does an investor care?

    Because liabilities discovered after investment become the new investors' problem. Unpaid taxes can carry penalties and interest, and in some jurisdictions directors can be personally liable.

    How a company keeps its books also reflects how carefully it is run.

    Example

    Diligence finds payroll tax arrears.

    Payroll taxes due over 9 months 180,000 Paid 0 Estimated penalties and interest 25,000 Liability 205,000

    The company's 2,400,000 of cash effectively becomes about 2,195,000 once this is paid (2,400,000 - 205,000). At 200,000 of net burn, runway falls from 12 months to about 11. More importantly, the investor now asks why taxes were not paid and what else has been deferred.

    The common mistake

    Treating all informal accounting as equally harmless, or equally alarming, instead of looking specifically for hidden liabilities.

    How it works

    Step 1: Reconcile to the bank

    Confirm the accounts match actual cash movements.

    Step 2: Confirm tax compliance

    Check filings and payments for payroll, sales and corporate taxes.

    Step 3: List related-party transactions

    Identify dealings with founders and their connected businesses.

    Step 4: Get written disclosures

    Ask for off-balance-sheet obligations to be disclosed in writing.

    When to use this

    During diligence on any company, especially those without audited accounts.

    When not to use it

    Do not demand audit-grade accounts from very early companies; focus on material risks rather than formality.

    How investors actually did it

    A recurring pattern: director liability for unpaid taxes

    Tax authorities in several jurisdictions can in certain circumstances hold company directors personally liable for unpaid payroll or withholding taxes, which is why unpaid payroll taxes are treated as a serious issue in diligence rather than an ordinary creditor balance.

    Some unpaid obligations follow the people running the company, not only the company.

    Do this now

    • Ask one company whether all tax filings and payments are current
    • Request a list of transactions with founders or connected businesses
