The Six Places a Contractor's Margin Leaks — and What It Costs to Close Them
· 14 min read · Written by Faceela Research & Editorial Team
A contractor who has been trading for fifteen years knows his business better than any consultant who walks through the door. He knows his rates, he knows which clients pay and which argue, and he can tell you within a few percent what a job should make before he prices it.
And then the job finishes and it made less than that. Not catastrophically less. Two points, three points, sometimes five. Enough to matter across a portfolio and never enough, on any single job, to launch an investigation.
Ask where it went and you get theories. The client was difficult. Material prices moved. The foreman was weak. Every one of those is occasionally true and none of them is the answer, because the same gap appears on the easy jobs too.
The gap has a structure. It is not one hole, it is six, and they are the same six in almost every contracting business we have opened up in this country. What follows is where they are, why each one is invisible from the accounts, and how to put a number on yours.
Why you cannot see them from the ledger
Start with the thing that makes this hard.
Every one of the six happens at a hand-off — a moment where a document leaves one person's hands and arrives in another's, and where the fact that would have priced it correctly stays behind with the first person. The estimator's build-up does not travel to the buyer. The instruction the foreman heard does not travel to the QS. The quantity issued from the store does not travel to the subcontract account.
And every one of them is discovered at the same place: month end, in the accounts, as a margin lower than the estimate. They arrive together, netted against each other, with nothing left in the record to say which of the six did it or what each was worth.
That is why the answer to "where did it go" is always a theory. By the time the number exists, the evidence has been gone for weeks.
The shape of it
Six leaks, one place they are all found
Leaks at · Tender to award
1. The package let above its own estimate
A trade goes out to tender and comes back priced. Whether the buy beat the estimate or lost against it is a comparison somebody has to make deliberately, and the award does not wait for it.
Found at: The final account
Leaks at · Instruction on site
2. The variation nobody raised in time
A consultant gives an instruction and the work is done that week. It is priced never, because the man who heard it is not the man who bills, and by the time they speak the notice period has run.
Found at: Never — absorbed
Leaks at · Measurement to certificate
3. Executed work left out of the claim
The measurement is rebuilt from scratch at month end against a deadline. Anything the quantity surveyor cannot reconstruct in time is carried forward, and carried forward again.
Found at: A later certificate, or not at all
Leaks at · Material issued
4. Material that left the store for another job
Free issue goes out against a subcontract at an allowed quantity and a wastage factor. Over-draw is a back-charge only if somebody sets issued against certified and prices the difference.
Found at: The stock count
Leaks at · Certificate to payment
5. The certificate that went out eleven days late
Every day between work executed and a certificate submitted is a day the contractor finances his client out of his own facility, at his own rate.
Found at: Cash flow, quietly
Leaks at · Completion to end of defects
6. Retention nobody chased
Held on you by the client and by you on your subcontractors, released in tranches on dates written into a contract that nobody put in a diary.
Found at: One to two years later
Month end, in the accounts
All six arrive here at once, as a margin lower than the estimate, with nothing left in the record to say which of them did it or how much each was worth.
The six
1. The package let above its own estimate
You priced the tender. Somewhere in that build-up is a number for blockwork, a number for painting, a number for the electrical subcontract. Then the job is won, months pass, and the trades go out to quotation.
The quotation comes back and the question that decides whether you made money is: did this buy beat the line in the estimate, or lose against it? It is a comparison someone has to make deliberately, against a document that by now lives in the estimator's folder, at a moment when the site needs the subcontractor on board by Sunday.
Mostly the award does not wait for that comparison. It gets made on whether the price looks reasonable, which is a different question with a different answer.
Found at: the final account, if anyone reconstructs it.
2. The variation nobody raised in time
The consultant walks the site on a Tuesday and says move the riser. The foreman moves the riser. It takes four men two days and it is done by Thursday.
It is priced never. The man who heard the instruction is not the man who bills, and by the time they speak about it — if they ever do — the notice period in the contract has run and the claim is dead on procedure rather than on merit.
This is the leak most contractors underestimate most badly, because there is no record of it anywhere. A variation that was never raised leaves no trace in any system. You cannot count what you did not write down, which means the true size of this one is always larger than the number you would guess.
Found at: never. It is absorbed.
3. Executed work left out of the claim
Month end. The QS has three days to produce the application, and the measurement is rebuilt largely from scratch — from drawings, from memory, from whatever the site sends over.
Anything he cannot reconstruct in time is carried forward to next month. Next month has its own deadline. Some of what is carried forward is carried forward again, and a portion of it is quietly never claimed at all.
Note what this is not: it is not a dispute with the client. The client would have certified it. Nobody asked.
Found at: a later certificate, or not at all.
4. Material that left the store for another job
Free issue goes out to a subcontractor against an allowance in his contract — a quantity per unit, plus a wastage factor. He draws more than that. Sometimes because of genuine wastage, sometimes because the material walked to a job that is not yours.
Over-draw becomes a back-charge only if somebody sets issued against certified, applies the allowed factor, and prices the difference before the final account is agreed. Three deliberate acts, none of which happens automatically, all of which have to happen while the subcontractor still has money coming.
Found at: the stock count, long after the leverage is gone.
5. The certificate that went out eleven days late
Work is executed. The application goes in late — because the measurement was not ready, or because the backup was being chased, or because the person who signs it was travelling.
Every one of those days is a day you are financing your client out of your own facility, at your own rate. This one does not reduce your margin on paper at all. It reduces the cash you have to trade with, which is the constraint that actually decides how many jobs you can carry.
Found at: cash flow, quietly, as an overdraft that is always a bit larger than it should be.
6. Retention nobody chased
Held on you by the client, and by you on your subcontractors. Released in tranches on dates written into a contract — practical completion, end of the defects liability period — that nobody put in a diary.
Two questions settle whether this one is leaking in your business, and you can ask them this afternoon:
Found at: one to two years later, if at all.
Measure your own six before anyone sells you anything
Here is the part that matters more than any product. You can size all six of these yourself, on your own numbers, this week. You need one live job of reasonable size and a couple of hours with the people who run it.
Do that and you will have six numbers instead of a theory. They will be uncomfortable and they will be yours. Every conversation you have with a software vendor after that is a different conversation, because you will be able to ask what their system does about your number six rather than listening to what it does in general.
Some of what you find will not need software at all. A discipline that nobody has written down — the buyer sends the comparison to the estimator before the award — closes part of leak 1 for the cost of a habit. If two of your six turn out to be small, close them with a rule and keep your money.
What closing them was worth to one contractor
We do this exercise with contractors regularly. One of them let us publish the result.
Blue Spark Electromechanical is an MEP contractor in Business Bay, Dubai. They put a system in that closed all six, and these are their own figures from the first twelve months it was live.
One contractor, twelve months live
Where AED 2.99 million a year was going
- Every package priced before it was awardedAED 940,000
- Variations that used to be absorbedAED 715,000
- Retention that came back on its dateAED 480,000
- Material that reached the job it was ordered forAED 385,000
- Certificates out eleven days earlierAED 265,000
- Back-charges raised against whoever caused themAED 210,000
Recovered in the first twelve months liveAED 2,995,000
The cost bar is on the same scale as the six above it. It is 2.5% of what was recovered — about nine days of it.
Two things about that ledger are worth saying plainly, because they are the two things a number like this is usually used to obscure.
None of it is new revenue. Not one dirham of it came from winning more work or charging more. It is money Blue Spark had already earned, on jobs they had already won, and were giving back. That is what makes it recoverable at all, and it is also what makes it invisible: nothing on a P&L is labelled "given back."
It is one contractor's result, not a forecast. Their six holes were the size they were. Yours will be different — possibly smaller, occasionally larger, and almost certainly distributed differently across the six. A contractor with a strong QS and a weak buyer has a different shape from one with the reverse. The exercise above is what tells you your shape. The ledger above tells you nothing about it.
What it does establish is the order of magnitude of the question. The implementation cost AED 73,450. That is drawn on the same axis as the six recoveries in the picture, which is why it looks the way it does — 2.5% of what came back, or roughly nine days of it. Even if your six are a fraction of Blue Spark's, the arithmetic does not get close.
Where the discipline has to live
Every one of the six is closed the same way, and the way is not a report.
A report tells you about leak 1 after the package is awarded. What closes leak 1 is the estimate line being on the screen where the award happens, so the comparison is not a task somebody has to remember. What closes leak 2 is the instruction being captured on site, by the man who heard it, into a register the QS reads before he builds the application — not an email he might be copied on. What closes leak 6 is the release date entering a diary on the day the contract is signed, and the diary chasing somebody.
That is the difference between a system that reports on the contract lifecycle and one that runs it. Both will show you a margin. Only the second one makes the margin come out right in the first place, because it puts the deciding fact in front of the person at the moment the decision is made.
If you want to see what that looks like when it is built specifically for a UAE contractor — the payment certificate cycle, retention on both sides, variations as a chain rather than a line — that is what Movinti is. It is our Odoo-based system for contracting businesses, and the Blue Spark ledger above is its case study, published with their permission.
But read that page after you have done the six-question exercise, not before. A contractor who knows the size of his own six is in a position to judge any system on the only ground that matters. A contractor who does not is being sold to, whatever the demo shows him.
The one thing to take away
Your margin is not leaking because your people are careless. It is leaking because six specific facts do not travel across six specific hand-offs, and the only place the six are ever added up is a P&L that arrives too late to act on and is too coarse to attribute.
Find out what yours are worth. Then decide what to do about them — with software, with a rule, or with nothing at all. In that order.
