Gaffer for
heating engineers.
Heating is installs in summer and breakdowns in January, with service contracts holding the year together. Gaffer keeps the installs on a project with stage payments, the breakdowns on a dispatch board that can be reshuffled at 7am, and the service contracts on recurring invoices that bill themselves. Quote, schedule, certify, invoice and get paid — with the 27 documents heating engineers actually use already in the account.


Priced quote templates for heating engineers, your own price book and good-better-best options. Customers accept and pay a deposit from their phone.
27 certificates and forms specific to heating engineers, filled in on the phone, signed on site and emailed as a PDF before you leave.
One tap raises the invoice from the accepted quote, nets off the deposit and sends a Pay Now link. Reminders chase for you.
Certificates and services with an expiry date become next year's work. Gaffer texts the customer a booking link before it lapses.
