Gas Engineer Job Management Software. As Precise as Your Work.
Gas engineers work to exacting standards — safety-critical, regulation-heavy, paperwork-intensive. Box Off is the gas engineer job management software that brings the same precision to your business admin that you bring to every installation.
The gas engineer problem.
Gas engineers have more admin than almost any other trade. Here's where it tends to go wrong.
Annual service reminders sent on post-it notes
You service a boiler in November. You stick a note somewhere to ring them next November. The note is lost by December. The customer gets their annual service from someone else. Box Off's reminders prevent exactly this.
Gas Safe paperwork on top of job paperwork
You've got regulatory paperwork, certificates, job records, customer details, invoices — the admin load for a gas engineer is significant. Having job records and customer details organised in one place takes a weight off.
"You never told me it would cost that much"
A customer-dispute classic. With a detailed, signed quote stored in Box Off, the price was always agreed in writing. No nasty surprises. No awkward conversations. No unpaid invoices because someone's dug their heels in.
How our gas engineer job management software works.
Never miss an annual service opportunity.
Log the service date against the customer record. Set a reminder for 11 months' time. Get notified when it's time to ring. Turn one-off services into regular, reliable recurring income.
All your customer records in one place.
Every customer, their appliances, their service history, their contact details. Find any record in seconds. Makes your admin significantly less painful and your service significantly more professional.
Every price agreed in writing, every time.
Quote clearly, itemise what's included, send a signing link. Customer agrees to the price before you do the work. When you invoice, there's nothing to dispute — it was all agreed upfront.
The features gas engineers actually use.

Full customer records with service history, appliance details, contact info and job notes.
Detailed Quote Builder
Itemise parts, labour and call-out charges. Send for signature. Price agreed upfront.
Job Records
Full record for every job — what was done, what parts were used, what was charged.
Invoice Management

Works on Your Phone
Check job details, update records and send invoices from wherever you are.
Results that matter.
"The reminders feature alone is worth it. I used to lose annual service customers because I forgot to follow up — I'd service a boiler, tell them to ring me next year, and then absolutely nothing would happen because they wouldn't ring and I couldn't remember who needed doing. Now I set a reminder when I log the job and I get notified automatically. I've retained five regular service customers this year that I'd have lost before. That's paid for Box Off about thirty times over."
Gas engineer job management software — FAQ.
What is gas engineer job management software?
Gas engineer job management software is an app that helps you manage your entire gas business from your phone — customer records, service reminders, quotes, job history, and invoices all in one place. Built for the admin-heavy reality of gas work, without requiring a desk or a laptop.
How does Box Off handle annual service reminders?
When you complete a boiler service, you log it against the customer record and set a reminder for 11 months' time. Box Off notifies you when it's time to follow up — so you make the call before the customer's even thought about it, let alone rung someone else. It turns one-off services into regular, reliable repeat income.
Can Box Off help me keep customer and job records organised?
Yes. Every customer has their own record in the CRM — contact details, appliance notes, full job history, and any follow-up reminders. Find any customer or any job in seconds. No more hunting through a folder of paperwork to remind yourself what boiler a customer has or when you last serviced it.
