What is a CVR, and does a small contractor need one?

A cost value reconciliation, universally shortened to CVR, is the monthly comparison of two numbers a busy job keeps in separate heads: the value the works have earned to date, and the cost incurred to earn it, measured to the same cut-off date. Value is not what you have invoiced or been certified; it is what the account is genuinely worth, your measured entitlement plus variations at your honest assessment plus any claim exposure, marked for what it is. Cost is not just what the purchase ledger has paid; it is everything consumed in the period, including plant on hire, labour worked and materials delivered that the invoices have not caught up with yet, which is why accruals are the difference between a CVR that flatters and one that tells the truth. Put the two together and it shows the margin the job is actually running at, and how that has moved since last month and why. A CVR is not a big-company luxury: the smaller the business, the less room it has to absorb a job that has quietly gone backwards, and the more it needs to know early. It need not be elaborate to be honest, only the value taken from the account, the cost accrued to the same day, and the margin movement explained. A director who reads one page a month like that is never ambushed by the final account.

Take a groundworks subcontractor on a JCT job that looks healthy: applications going in, certificates coming back, cash arriving, no CVR because the ledger looks fine. What the ledger does not show is that the muck-away rate came in well over the tender allowance, three loads of imported stone were tipped against an order whose invoices are still weeks out, and a chunk of the groundworks variation has been applied for but assessed by the contractor at half. On paper the job is making money; in truth it slipped below its tender margin around month three and nobody looked. Run a monthly CVR on the next job, value off the account and cost accrued to month end, and the margin drop shows up in the first period it happens, tied to the muck-away rate, so the director prices it into the next tender and pushes the variation while the evidence is fresh.
