Frequently asked questions
Got a question we haven't covered? Talk to our team.
What AI features does Gas Engineer Software have?
Boiler AI Assist answers boiler questions from the manuals built into the app. AI Quoting and Invoicing turns a few words about the job into a tidy, itemised draft. And the AI Receptionist, which is on the way, answers your calls and books work in when you can't get to the phone.
Can I trust what the AI gives me?
Treat it as a fast first draft, not the final word. Boiler AI Assist links the exact manual page behind every answer, so you can check it in a tap. With quoting and invoicing, you set every price and read it over before anything goes out. The features are new and we keep improving them, but you always have the final say.
How does Boiler AI Assist work?
Ask it a question and it finds the right manual, pulls the answer, and shows you the page it came from. Fault codes, reset steps, part numbers, that sort of thing, without searching for the manual.
How does AI Quoting and Invoicing work?
Type or say a few rough words about the job. The app writes it up as a professional, itemised quote or invoice, ready to send with a payment link. You check the figures first. The AI does the typing; the pricing is still yours.
What is the AI Receptionist?
It answers the phone when you're on the tools, takes the customer's details and the problem, and books the job straight into your diary. It's coming soon, and we'll let you know the moment it's ready to try.
Do the AI features cost extra, and can I try them?
AI features in GES are available on the Pro plan. All can be tried for free with a 14 day free trial.
