Ask a founder which numbers they trust most and the answer is usually the same: last year's audited accounts. An auditor checked them and signed them off, so the starting point must be solid.
Not always. An audit looks at the records it's given. If those records are incomplete, the gap can pass through the audit and into every year that follows.
The pattern we see
One client, an award-winning attraction planning to triple in size, came to us with books three to four years behind. They sat with an outgoing accountant on an old system, and an audit was coming.
Years of bank statements had never been recorded, and some were locked. Cash taken at the gates had never reached any ledger. VAT returns had been filed with nothing reconciling them to the books.
The only fixed point was the last audited balance sheet. When we checked it against the bank, it was wrong: it left out bank accounts the business really held.
Why an error in the audited accounts matters so much
The audited balance sheet is the opening position for everything after it. Every later year starts from it, every tax return leans on it, and every lender or investor reads it first. If it's wrong, the error doesn't stay in one year. It carries forward, quietly, until someone checks it against the source.
Three signs your starting point needs checking
- Your books are behind, or have changed hands. A switch of accountant or system is when records get lost or carried over incorrectly.
- Some income never touches the bank. Cash sales, deposits and payments taken outside the main account are easy to miss, and easy for an audit to miss too.
- Your tax filings and your books don't tie. If nobody can show how each return reconciles to the ledger, something in one of them is wrong.
What changes when you get it right
For the attraction, the result was books tied to the bank to the fils, cash sales recorded in a compliant manner for the first time, and live visibility of cash, receivables and payables. The expansion is now assessed on real numbers rather than estimates. In the owner's words, they “now walk into every audit with confidence”.
Where to start
Take your last audited balance sheet. For every bank account, compare the balance with the bank statement on the same date, and check that every account the business holds appears on it. If anything is missing or doesn't match, fix that before you build anything else on top of it.
