If you have been asked for "the CVR" on a job and wondered exactly what is being asked for, this is a plain explanation. It covers what a CVR is, what goes into it, and why it is so often late or wrong.

CVR in one paragraph

CVR stands for cost value reconciliation. It is a regular comparison of what a job has cost so far, including money you have committed but not yet paid, with the value you have earned from the work. The point is simple: to know whether a job is making or losing money while there is still time to do something about it.

It is not a report written once at the end. Done well, it is a short, repeated check that the commercial manager, finance lead and operations director can all read in the same way.

The arithmetic is easy. Getting complete, current cost and value onto one page is the hard part, and that is what most of this article is about.

What goes into cost

Cost is what the job has used, plus what you have already agreed to spend on it. Both matter. A CVR built only from invoices received is looking backwards.

  • Labour. Your own people's time on the job, at the cost rate your finance lead uses.
  • Materials. What has been delivered and used, including goods ordered but not yet invoiced.
  • Plant and equipment. Hired or owned, charged to the job on the basis your business uses.
  • Subcontractors. Work invoiced so far, plus work done or ordered where no invoice has arrived.
  • Other site costs. Items such as welfare, waste and transport that belong to the job.

One item is easy to miss: committed cost. If an order has been placed or work has been done but the invoice has not arrived, it still belongs in the CVR. Leave it out and the job looks better than it is, until the invoice lands.

What goes into value

Value is what you have earned from the work, which is not the same as what you have been paid. Depending on your contract, it can include:

  • value certified or applied for so far;
  • work done but not yet certified or applied for;
  • variations that have been instructed and valued.

How each of these is treated, and whether work done but not yet certified counts at all, depends on your contract and on your business's accounting policy. That is for your finance lead to decide, not for a spreadsheet template. Write the rule down so every job's CVR is built the same way.

Leave out anything you cannot support. If you cannot show that the work was done, or that a change was instructed, treat that value as uncertain and say so.

A worked example, with invented numbers

Imagine one job at month end. The table sets cost against value.

A hypothetical CVR for one job (illustration only)
ItemAmount
Labour£28,000
Materials£22,000
Plant and equipment£4,000
Subcontractors, invoiced£16,000
Subcontractors, committed but not yet invoiced£6,000
Total cost, spent and committed£76,000
Value certified or applied for£90,000
Work done, not yet certified£6,000
Variations instructed and valued£4,000
Total value£100,000
Gap: value less cost£24,000
Gap if work done, not yet certified, is left out£18,000

Cost, spent and committed, is £76,000. Value is £100,000. The gap is £24,000 if work done but not yet certified counts as value, and £18,000 if it does not. Which applies is a policy decision for your finance lead. Now read what each line is telling you.

  • The £6,000 of committed subcontract cost is real cost even though no invoice has arrived. Leave it out and the job looks £6,000 better than it is.
  • The £6,000 of work done but not yet certified is work you have carried out and not yet been able to claim. Whether it counts in the CVR is a policy decision.
  • The £4,000 of variations is value only if the change was instructed and has been valued. If the instruction was verbal and nobody has priced it, treat it as a risk, not as value.

Treat the gap as margin to date, not profit. It ignores cost still to complete, retention and overheads, and valuing work early can overstate it. Those matters are outside the scope of this explainer, but they affect how you read any CVR.

Notice how errors can hide each other. Suppose the committed subcontract cost is missed, so cost reads £70,000, and the variations are never recorded, so value reads £96,000. The gap now shows £26,000 against a true £24,000. It looks close, yet two things are wrong. A reasonable-looking total can conceal larger errors underneath, so check the lines as well as the total.

How often, and who uses it

Monthly, and again around valuation or application dates, is a sensible rhythm. A large or risky job may justify a shorter cycle.

  • Commercial manager or quantity surveyor. Usually owns the value side.
  • Finance lead. Owns the treatment rules and checks that cost is complete.
  • Operations director or contracts manager. Explains what is happening on site.
  • Managing director. Wants to know which jobs need a decision.

The review works best as a short meeting with a named owner, not a document emailed round. Ask the same three questions each time. What has changed since last time? What is not yet in the numbers? What do we need to decide?

Why CVRs go wrong

Where job information lives in several places, the same handful of problems keep appearing.

  • Late costs. Timesheets and site purchases arrive after the CVR is run, so labour and materials are understated.
  • Missing commitments. Subcontract and purchase orders sit with the people who placed them, not in the job record.
  • Unvalued variations. A change is agreed on site, the work is done, and nobody prices it before the final account.
  • No evidence. Value cannot be claimed because the photo, sign-off or delivery note cannot be found.
  • Many versions. Three people hold three copies of the spreadsheet, each with a different budget.

None of this is a failure of effort. It is what happens when the information a CVR needs is spread across inboxes, phones and files.

What makes a CVR trustworthy

  1. Costs are coded to the job when they arise, not at month end.
  2. Variations are recorded when they are instructed, with who instructed them and when.
  3. There is one live job status that everyone looks at.
  4. There is a single source for the budget and for approved changes.
  5. A named person owns the review and its follow-up actions.

If you can only fix one thing, fix the timing of variations. A variation recorded on the day it is instructed is easier to value, easier to evidence and easier to agree.

Where a system helps, and where it does not

A system can hold the information a CVR needs in one place. Our job management software gives you job status, cost and margin visibility, and holds job notes, documents, evidence and approvals against each job. CVR-style reporting and variations tracking are not off-the-shelf features. They are built to your requirements, so they follow your cost codes and the way your contracts treat value.

A system does not replace commercial judgement. It will not decide whether uncertified work counts as value, or whether a disputed change is likely to be agreed. People still make those calls. What a system can do is make sure they make them with complete, current information.

Not every business needs one. If a disciplined spreadsheet, kept in one place with one owner, gives you a CVR you trust, keep it. If you are weighing the options, our guide to bespoke and off-the-shelf job management software sets out the trade-offs, and the construction page shows how the systems fit that sector.

Could you produce a reliable CVR today?

Take your biggest live job and answer these six questions honestly.

  1. Do you know every cost committed to the job, including orders where no invoice has arrived?
  2. Is every variation recorded, instructed by someone named, and valued?
  3. Can you show evidence for the work you are claiming as value?
  4. Is there one budget, one status and one version of the numbers?
  5. Did last month's labour and site costs reach the job before the review was run?
  6. Does a named person own the review, and does anything happen as a result?

If you answer no to two or more, the problem is probably the flow of information into the CVR rather than the CVR itself. Our article on reducing the time between job completion and invoicing tackles a related problem from the other end.
