From enquiry to sign-off in one system — gas engineer software, scheduling, quotes and invoicing. Built for gas businesses doing boiler services, landlord inspections, breakdowns, installs. Less paperwork, more work.
Certificates asked for two years later
Annual services that quietly stop renewing
Registration details retyped onto every document
One customer record carries the whole business — from the first enquiry to the signed job sheet and the invoice.
Every enquiry with the address, the history and a status, in a funnel you can read at a glance.
Survey, photos, job sheet and a signature on the phone, on the job.
Quotes and invoices in your own branding, emailed with a payment link on them — card, Apple Pay or Google Pay, or a transfer with the invoice number as reference.
Split from the moment the work is recorded, which is what makes a CIS invoice come out right instead of being reconstructed.
No signal in the cellar or on a new build? The app keeps photos, sign-offs and hours on the device and sends them when the connection returns.
Follow-ups, appointment reminders and payment reminders switched on once. Built in, no separate tool and no extra subscription.
Jobs onto engineers and onto the week, with appointment reminders going out on their own.
A tidy PDF with photos and your branding, produced when the job is signed off.
Start and stop on the job in the app; the hours land on the invoice as a labour line with one click, so nothing shrinks on the way.
Recurring work with its own renewal date and its own reminder, and invoices raised without anyone remembering.
The engineer sees the survey, what was agreed and what was flagged last time — and you decide per photo and per message what goes to the customer.
Incoming mail lands against the right customer and the right job.
Bring your customers and price lists in from Excel or CSV in one go. No retyping.
Type what you want to change and Quandron points at where it is set. Configuring works without a manual.
Enter your logo or your website address and Quandron picks up your colours for the app, the quotes and the invoices.

Against the property and the appliance, not against the person paying. Properties change hands; the boiler stays where it is.
Yes. The renewal belongs to the contract, so it happens in the weeks everyone is too busy to think about it.
No. Registration is between you and the register; the software carries the number onto the paperwork you send out.
