Profit Engine

Job costing software

Job costing software that shows your profit before, during and after every job

Plenty of construction companies are busy and still short of money. The reason is usually hidden in job costs: extra hours nobody logged, materials ordered twice, a quote that was too optimistic. Profit Engine is job costing software for construction and roofing that keeps the quote, the real costs and the margin side by side.

Quoted vs actual, on every job

Every job starts with the costed quote: materials, labour hours, plant, scaffold, transport and overheads. As the job runs, crew daily reports and purchases are recorded against it, so you can see quoted versus actual in real time – not three months later when the accountant finishes the books.

  • Margin per job, per crew and per type of work
  • Early warning when hours or materials run over budget
  • Labour, materials, plant and subcontractors tracked separately
  • Change orders priced and added to the job in seconds

Estimates that learn from your real costs

This is where Profit Engine is different. When a task takes longer than estimated – say chimney flashing takes three hours instead of two and a half – that real time is fed back into your labour norms. The next quote uses your actual performance, so over weeks and months your estimates get sharper and underpriced jobs disappear.

Quote in minutes. Profit on every project.

Profit Engine launches on 28 October. The first 100 UK roofing companies get 50% off for 12 months, a free month, and free onboarding.

Why job costing matters for UK contractors

Construction margins in the UK are thin, and cash flow is squeezed by retentions, CIS deductions and slow payers. Knowing exactly which jobs make money – and which quietly lose it – is the difference between growing safely and growing into trouble.

Frequently asked questions

What is job costing in construction?
Job costing means tracking the actual labour, materials, plant and subcontractor costs of each job against what you quoted, so you know the real profit of every project.
Does Profit Engine replace my accounting software?
No – it complements it. Profit Engine handles quoting, job costing and cash flow per job; your accountant still uses their accounting software for the company books.
Is it suitable for small roofing companies?
Yes. It is designed for companies with one to twenty crews that want big-company control without big-company admin.
