Profit doesn't leak in one place. It leaks everywhere.

A typical £1M field service business loses around £150,000 a year to admin, rework and tools that don't talk to each other. Here's where it goes.

£150K

Lost annually

By the average £1M field service operator running on disconnected tools.

18.5hrs

Admin per engineer

Every week. Time that should be spent on the road generating revenue.

35

Tasks per job

Across scheduling, dispatch, job sheets, invoicing and chasing payment.

60+ days

Invoice to cash

Money sat in the customer's pocket while you've already done the work.

Thin margins aren't a skills problem. They're a systems problem.

Take the waste out of the day, and the profit shows up. Here's what BigChange customers typically see.

+4

Extra jobs per field operative, every month

Smarter scheduling, optimised routes and less admin mean each engineer takes on more work without you adding headcount.

10%

Reduction in fuel costs

Live tracking and intelligent route planning cut wasted miles. Add CANbus driver behaviour data and the savings stack up quickly.

8hrs

Admin time saved per week

Digital job sheets and on site eSignatures flow straight into invoicing. Your back office stops processing paper and starts adding value.

10hrs

Less travel time per week

Intelligent dispatch puts the right engineer on the nearest job. Faster invoicing means you get paid quicker, too.

One platform. Every workflow. The entire business.

CRM

The straight answers, before you book.

If you've made it this far, you're weighing things up. Here's what most people ask before saying yes.

How long does implementation actually take?
Most field service businesses are live in four to six weeks. The first two weeks are configuration and data migration. The rest is workflow build, training and a soft go live. Your dedicated Customer Success Manager runs the whole thing alongside you.
What happens to the data we already have in our current systems?
Customer records, jobs, invoices, sites and contacts all migrate across as part of onboarding. We've handled migrations from Sage, Xero, QuickBooks, every major scheduling tool and a lot of homegrown Excel. If you're worried about a specific source, ask in your demo.
Will my engineers actually use it?
JobWatch is the bit that lives on the engineer's tablet. It's been refined over a decade with field operatives in mind, runs offline, and is genuinely faster than paper for routine jobs. Most teams pick it up inside a shift. Holdouts usually come round once they see invoicing happen on the day.
Is there a contract minimum?
Standard contracts run 36 months, which gives our team the runway to deliver real ROI rather than just sell software. Most customers see payback inside the first quarter. We'll walk through the maths in your demo.
What does support actually look like at 2am on a Sunday?
Our RoadCrew customer service team is in Leeds, available 24/7, and answered by real humans. Standard onboarding tier includes business hours phone, the Elite tier includes 24/7 phone with a designated success rep. Average ticket resolution is under 10 minutes.
How does pricing scale as we grow?
Per user, per month, no surprise tier jumps. As you add engineers you add JobWatch licences, that's it. The platform itself doesn't get more expensive because you're billing more invoices or scheduling more jobs.
