The Six Places a Contractor's Margin Leaks — and What It Costs to Close Them
Every one of them happens at a hand-off, and every one is discovered at month end as a single margin figure with nothing left to say which did it. Here is how to measure your own six before anyone sells you a system.

Measuring What Automation Actually Paid Back
The business case said it would save two hundred hours a month. A year later nobody can tell you whether it did, because the hours were never counted before and the headcount never changed. That is not a measurement problem. It is a claim that was written to be unfalsifiable.

Your Largest Client and Your Best Client Are Rarely the Same Client
Revenue per client is the number every firm already has and the least useful one it owns. What it costs to serve that client is the number that decides everything, and almost nobody has it.

You Paid for the Whole Board and Costed Only the Part You Used
Materials are 55–70% of the cost of a job in this trade, which makes yield the margin. Yet the cutting list lives on one machine, the offcut is stood against a wall with no name, and the wastage factor is the same number for every material in the building.

Nobody Decides to Buy Dead Stock. It Is Decided One Reorder at a Time
There is no meeting at which a trading company resolves to tie up capital in stock it will never sell. There is a reorder point set three years ago, a report built from movement so an item with no movement cannot appear on it, and a phrase — we might sell it — that has never once been refused.

You Delivered Perfectly Into a Room That Was Still Being Plastered
A finished unit delivered early is not progress. It is a liability that needs storage, protection and somebody to blame when it is damaged — and the phone call that confirmed the site was ready confirmed nothing that can be checked.

The Cost You Paid on the Client's Behalf and Never Got Back
A fee paid from a partner's card at four in the afternoon is a cost with no engagement attached to it. Whether it is a disbursement or a recharge was decided at that moment — and by month end nobody can prove which, so it becomes neither.

The 240 Centimetre Wardrobe Was Priced as a 180
The estimate was not careless. It was built from a drawing and a memory of a job that resembled this one, and nobody ever went back afterwards to find out whether the memory was true.

The Fee Was Fixed. The Work Was Not
Firms argue about pricing models as though one of them were correct. All five are correct somewhere. What separates them is not the number on the proposal — it is what each one obliges you to measure, and a firm that cannot measure it has not chosen a model, only a way of being surprised.

Three Costs Never Reach the Job, and All Three Are Real Money
Your job cost sheet looks complete because absence has no row on it. Rework, external finishing and post-handover attendance are all incurred, all paid for and all booked somewhere that does not name the job — which is why the jobs you think are profitable are the ones you keep bidding.

The Shortage Was Created Eight Weeks Ago and Discovered on Cutting Day
The board is on the saw and the hinge is not in the store. Nothing went wrong that morning. The requirement existed the day the drawing was approved, and the purchase order was raised the day somebody happened to notice.

Approved on WhatsApp, Built on Monday, Invoiced Never
The client asked for the shelf to move. The foreman said no problem. It was built on Monday and it was never priced, because the chain that would have priced it starts three links later than the request.

The Margin Was Calculated on the Supplier's Price. The Cost Arrived Six Weeks Later
A purchase order carries one number. The cost of the goods it buys is assembled over the following two months out of freight, duty, clearing, handling and demurrage — and by the time the last invoice arrives, the stock has usually been sold at a price set from the first one.

Three Tons of Steel Are at the Galvaniser and Nobody Knows Which Job They Own
Galvanising is always outside. Powder coat and duco usually are. The material leaves your yard, stays yours, and disappears from every stock report you own — along with the answer to whose job it belongs to and what it is worth.

Everybody Has the Price List. Almost Nobody Sells at It
Between the price in the list and the money that stays in the business there are seven layers, each approved by a different person, none of them visible on the same document as any other. The result is the same customer buying the same item at four prices across three branches, and nobody able to say which one was right.

You Recorded a Hundred, Billed Seventy, and Called It a Full Job
A fee agreed at a discount is a pricing decision. A fee written down at invoicing is a delivery failure. They reduce the same number by the same amount, and a firm that codes them the same way can never tell which of its problem is which.

The Third Revision Was Free Because Nobody Wrote Down That the Second Was the Last
Scope in a services engagement is made of three things: what was written in, what was written out, and what was never mentioned. Every overrun lives in the third, because it is the only one with no document and no owner.

Production Started Before the Client Signed. Everything After That Is a Negotiation
One moment decides whether the next change is billable. It is not the moment the client changes his mind — it is the moment production was released, and whether anybody wrote down which revision it was released against.

Fifth Floor, No Lift, Priced as Ground Floor
Installation is quoted as a percentage of the joinery and delivered as an address, a lift booking, a security pass and a two-hour window. None of those were unknowable. Nobody was asked to write them down.

The Job Closed in the System and Two Men Kept Going Back
The last invoice is raised, the job is closed, and the cost tail runs for months afterwards — two men, a van, a spray booth and a store issue with no job number on it. The margin the system reports is the margin before any of that happened.

The Margin You Earned in March and Claimed in November
A supplier rebate is earned one invoice at a time and collected once a year, and in between it exists nowhere. So the buyer negotiates without knowing how close he is to the next tier, and the credit note, when it finally comes, lands in an account that leaves every item's gross margin exactly as wrong as it was.

A Timesheet Filled In on Friday Is a Memory, Not a Record
The reconstructed week always adds up. It sums to forty hours, spreads sensibly across three clients, and passes every review a firm actually runs — which is exactly why nothing in the firm can detect that it is fiction.

The Work Is Finished. The Invoice Is a Decision Nobody Made
Unbilled work in progress is money you have already spent on salaries and not yet asked anybody for. The chain from work done to cash has six links, five of them have an owner, and the one that does not is the link that turns cost into revenue.

You Pay for Every Hour and Sell About Half of Them
Six different things get called utilisation, every firm quotes the one that flatters it, and two partners arguing about the number are usually standing four rungs apart. The useful question is not how busy people were last month. It is how much of next month is already sold.

Nobody Steals This Money. It Is Simply Never Asked For
Every system a contractor owns reconciles what was claimed against what was certified. Nothing reconciles what was built against what was claimed. Work that falls into that gap is not late — it is gone, and no report ever raises an error.

The Bill You Priced Is Not the Bill You Are Building
Three bills of quantities exist on every job — the one the estimator priced, the one the contract holds, and the one being built. Margin lives in the gaps between them, and most contractors cannot see any of the three at once.

Most Variation Money Is Lost Before Anyone Argues About Price
A variation becomes money through a chain — instruction, notice, records, valuation, agreement, certificate. Every link has a deadline. Contractors rarely lose on the rate; they lose on the link nobody was tracking.

Every Contractor Has a Profit Figure. Most of Them Are Reading a Timing Difference
Cost value reconciliation compares what a job has earned against what it has cost, at the same date. It fails almost always for one reason: value and cost arrive late by different amounts, so the margin you read mid-job is mostly lag.
