AI Quote Generator.
Quoting for gas engineers.
Boiler swaps, new installs, the certificate - describe the job once and the quote writes itself, looks like it came from a proper firm, and gets accepted online.
No signup, no card needed to try it.
Say it like you would say it
"Quote Mr Lowe 2300 for a Worcester combi swap including flue, magnetic filter, system flush and Gas Safe certificate, valid for 30 days"
That is the whole job. The AI writes the lines, deterministic code does every sum in exact pence, and the quote goes out with your logo on it and a valid-until date printed.
The boiler quote
Three engineers quoted. One looked professional.
A new boiler is a distress purchase decided in a day. Customers pick the engineer whose quote they can understand and trust, not always the cheapest.
The parts list
Boiler, flue, filter, flush, controls, the certificate - a clear list is reassuring. A single number makes them go and get another quote.
Model swaps
They found the next model up online. Revising a quote should be one sentence, not a rewrite that risks a wrong total.
Chasing a cold house
When the heating is off they decide fast - but not always with you. A same-day quote with an accept button closes the door on the second call.
One tap to yes
They accept it on their phone, standing in the garden
Your quote goes out with a link. They open it, see the whole thing exactly as you sent it, type their name and tap Accept. No reply to write, no call to make, nothing to remember later - which is what usually kills a quote.
- No account, no app, no password. They tap the link and it opens
- Works on a phone, which is where they will read it
- Accepting stops the follow-ups the same second, so nobody gets chased after saying yes
- Their name, the date and their device are recorded as evidence of agreement
You see it the moment it happens: the quote turns green on your list, with who accepted it and when. Included from Starter.

Why your accountant can relax
The AI writes. It does not count.
Language models are good with words and unreliable with arithmetic, so DocMason only lets them do the first part. Every figure on a document you send is worked out by ordinary code, in exact pence, the same way every time.
It is the difference between a tool you check afterwards and one you can send without reading twice.
- VAT, discounts and totals calculated in code, never by the AI
- Money held in exact pence, so rounding cannot drift
- Every email sent on your behalf is stored in full, so you can read exactly what went out and to whom
- Your data hosted in the EU, never used to train AI models
FAQs
Questions from gas engineers, answered straight
The free tier, online acceptance, and how quoting fits the way gas engineers actually win work. Everything else is on the full page.
Something else on your mind? Ask a human.
Can the customer accept the quote online?
Yes - from the Starter plan the emailed quote carries an accept link: one tap and it marks itself accepted in your dashboard. The button stops after the valid-until date.
Can I change the boiler model after quoting?
Say it in the chat ('swap to the 30kW, add 180') or edit the line in the form; every sum is recomputed in exact pence and the revised quote supersedes the old one.
What about the deposit?
When the quote is accepted, one click turns it into an invoice; a deposit invoice is raised from one sentence and the dashboard tracks what is still owed.
Is it really free?
Yes. Build and preview a quote with no account at all, and create a free account when you want the PDF. The free plan includes 3 quotes and 3 invoices every month with all 26 designs - no card needed. Starter at 9.99 GBP a month makes them unlimited and adds emailing with the online accept link.
Does the AI do the maths?
No, and that is deliberate. The AI reads what you typed; plain deterministic code computes every total, discount and VAT figure in exact pence. AI is good at language and bad at arithmetic, so it only does the first one.
