What we do
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.
Financial due diligence tests the ledger: earnings adjustments, net debt, normalised working capital, worked from the trial balance and management accounts. Essential, and your lender will insist on it. It stops there.
The deal is decided below it. Retention, real margin, cash needs and capacity live in the order book, the job sheets, the TMS and the ERP. Few diligence teams open them, and rarely at a price that suits a £5-50m deal.
We read that layer, transaction by transaction, tied back to the ledger so the totals agree. Then we show you where the detail does not, and what it is worth.

How we answer it
Management accounts tied down to the order, invoice and job records underneath them.
Why it matters to the price
The totals usually agree. Where the detail does not is where your questions to the seller come from.
Most people who can read a P&L can't pull apart millions of transaction lines, and most who can pull them apart can't read the P&L. Diligence below the trial balance needs both, joined in one analysis.
Transaction-level diligence has usually been a large-deal luxury. Fixed at £15,000 per target, it fits the deals where an average hides the most.
