Operator diligence for buyers
Financial due diligence stops at the trial balance.
We start below it.
Nobody has to be hiding anything. The ledger records every sale correctly. It just cannot tell you which customers come back, which jobs lose money, or whether the operation can carry the plan in the information memorandum.
Before you buy a £5-50m business, we rebuild its revenue, margin, cash and capacity from its own orders, invoices and jobs, and show you where the data room story and the transactions part ways. Alongside your financial due diligence, not instead of it.
For buyers.
Before you sign, know whether the business underneath the numbers is the one you are paying for: which customers stay, which jobs make money, how much cash it really needs.
