37% sales increase, same size team - North West engineering firm

A specialist building services contractor wanted to take on more work without taking on more people. Its engineers were skilled. The limit was everything around the work.

We've kept the firm anonymous. Here's what changed.

The brief

The firm's owners could see where the pressure sat: admin. Every job meant paperwork: job sheets written up by hand, quotes retyped into the office system, and invoices chased by phone.

Hiring was one answer. We looked at the other: changing how work moves through the business.

What we did

We started where every engagement starts. We sat with the people who do the work and mapped it step by step: who touches each job, which system it lives in, how long each step takes.

Then we ranked what to fix by what it would return, and built the top of the list inside the tools the team already used. That meant one digital job sheet that engineers fill in on a phone, which feeds the quote and the invoice automatically. A live view in the office shows the status of every job, with automatic reminders for anything late.

What changed

  1. Sales rose 37%. Quotes went out faster and more of them were won. Over the 12 months after go-live, sales were 37% higher than the 12 months before, measured from the firm's own accounts.
  2. Admin time fell by 18 hours a week. The office team logged their time for four weeks before the build and four weeks after.
  3. The same team carried the extra work. No new hires were needed. Headcount stayed the same across the office and the field.

Why it worked

The work didn't change. The route it took through the business did. Time that went on admin went back into the work that earns. Quotes now go out the same day as the visit, and engineers spend more of their week on site.

Skilled people held back by paperwork is common in engineering and the trades. Fix the route, and the same team can carry more.

Who still decides

AI does the repetitive part. A person approves what matters. That's how we build everything, and it's how this firm runs today. The office approves every quote before it goes out, and engineers sign off each job sheet on site.

If you can tell us where the hours go, we'll tell you whether AI can help. If it can't, we'll say so.
