You Know What You Quoted. Do You Know What You Actually Kept?
Ask an owner-manager what they charge for the work and they'll tell you without blinking. Ask what they actually kept once the job ran, once the changes were accounted for, once the slow-paying customer was chased, once the quiet cost creep was stripped out, and the answer gets a lot less certain.
The gap between pricing and keeping
Pricing is a decision made once, at the start. Margin is what survives everything that happens after: variations that never get re-priced, a customer who's grown to a share of the book nobody quite noticed, cash that looks steady on the statement until you work out how many weeks it would actually cover if the taps turned off.
None of that is one bad call. It's the accumulation of a hundred small ones, made without the numbers in front of you, because running the job leaves no time to watch it from the outside.
What I've seen this look like
I've seen the same gap at a much bigger scale, too. On a multi-billion-pound engineering contractor, the estimating and the change-control process were meant to protect the margin on every job, but for years they ran on disconnected spreadsheets. A variation on site could go unbilled for months before anyone in the numbers noticed it had happened.
The fix wasn't a better spreadsheet. It was one system that connected the estimate, the change log and the cost, so a change on site showed up in the numbers the same week, not the same year. That single link, pricing talking to change control talking to the actual cost, was the biggest lever on margin the business had.
The scale is completely different for an owner-managed business. The principle isn't. If pricing and change control don't talk to the numbers in real time, the margin leaks quietly, and nobody sees it until it's already gone.
Commercial management is a discipline, not an event
This isn't a once-a-year exercise, and it isn't only relevant if you're heading towards a sale. It's the ongoing discipline of knowing your cash run-rate, your true margin once the noise is stripped out, and how much of your book sits with too few customers, while the work is live, not after the fact.
That read, the cash movement, the concentration, the true cost shape behind the price, is one strand of the Diagnostic I run for owner-managers. It sits alongside the market position, the ownership picture and the buyer-readiness questions, so an owner gets the full outside view in one pass.
Start with the question
You don't need a forensic rebuild to start. Begin with the question itself: if the work stopped tomorrow, how many weeks would the cash in the business actually cover, and how much of your income really sits with one or two customers? Most owners find the honest answer takes longer to reach than it should.
If you want that read done properly on your own numbers, book a call.
