Gaffer for
air conditioning engineers.
F-Gas compliant air conditioning installation, service, and commissioning workflows. Quote, schedule, certify, invoice and get paid — with the 20 documents air conditioning engineers actually use already in the account.


Priced quote templates for air conditioning engineers, your own price book and good-better-best options. Customers accept and pay a deposit from their phone.
20 certificates and forms specific to air conditioning 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.
20 documents, ready for air conditioning engineers.
Each one is a proper digital form — the fields the regulations expect, signature capture, photo attachments, a PDF the customer can keep and an expiry date Gaffer tracks. Completed on the phone, offline if it has to be.
