Gaffer for
air conditioning engineers.
Air conditioning is an F-Gas business with a compressor attached. Every system over the threshold needs its leak check at a fixed interval, and the record has to stand up if anyone asks. Gaffer keeps the F-Gas periodic leak check register against each unit on each site, tracks when the next check falls due, and sends the facilities manager a booking link before it does. Quote, schedule, certify, invoice and get paid — with the 20 trade documents air conditioning engineers actually use already in the account.
Where two names look alike they are different documents — a notification is not the certificate that follows it, and two schemes covering the same work each want their own form. If you think one is missing, or that one of these is redundant, say so and we will change the pack.


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 trade documents ready for air conditioning engineers — 10 written for this trade, 10 shared with others — 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.
