Construction
The margin is decided at quote and lost in variations.
Construction businesses rarely fail on the work. They fail on estimates built from memory, changes nobody billed, and invoices raised weeks after the value was delivered.
How the business actually runs
Before any software is discussed.
An enquiry becomes a site visit, then an estimate assembled from a spreadsheet and experience. Work starts. Things change — they always change — and the changes are agreed verbally on site. Information lives in photos, messages and a site diary. Valuations and invoices are compiled at the end of the month from whatever can be reconstructed.

- fit-out
- civils

Where the money leaks
Four leaks we see in almost every one of these businesses.
Not generic inefficiency — the specific places where revenue, margin or time escapes a construction business.
- 01
Estimates without a price history
If last year's actual costs are not attached to this year's estimate, every quote is a fresh guess — and the error compounds across a pipeline.
- 02
Variations agreed on site, billed never
The single most common margin leak in the sector. A change captured on a phone in two minutes is billable; the same change remembered three weeks later is a negotiation.
- 03
Site information in a messaging app
Photos, instructions and sign-offs in a chat thread are invisible to the office, impossible to search and worthless in a dispute.
- 04
Cash behind the work
Progress applications raised late push the whole cash cycle out, which is why profitable builders still run short of money.
The system
One connected flow, end to end.
Each stage feeds the next, and every stage is measurable. This is the shape of what we would build — the detail is decided with you.

- Estimating with a cost library that learns
- Job and programme management
- Site app for photos, instructions and sign-off
- Variation capture at the point of change
- Progress applications and invoicing
- Margin reporting by job
- Quote-to-win rate
- Variations captured against variations agreed
- Realised margin against estimated margin
- Days from work done to invoice raised
A worked example
Illustrative, with the assumptions stated.
Assume
- Say a contractor runs 20 live jobs with an average value in the tens of thousands
- Each job accumulates several agreed changes
- A portion of those changes are never invoiced
What changes
- Estimates are built from a cost library updated by what jobs actually cost
- Variations are captured on site, with a photo and a signature, the moment they are agreed
- Site records are searchable by job rather than scattered through a chat
- Applications and invoices are generated from progress, not reconstructed at month-end
Assumptions for illustration only. In practice we start by pricing the variation leak on your last ten completed jobs — it is usually the fastest number to recover.
Is this you?
Worth a conversation if any of these are true.
And worth saying plainly when they are not.
- Estimates rely on one person's judgement and a spreadsheet
- Nobody can list the variations agreed on site this week
- Site information lives in a messaging app
- Invoicing lags the work by weeks
If your order book is full and your constraint is labour or materials, software will not pour concrete. Fix the quoting and the variations, then stop.
