AI quotes that sound like you, not every other AI

There's a tell with AI-generated quotes. Customers have started spotting it. The phrasing is too polite, the line items are too tidy, the margin notes all sound like they were written by an assistant who's never held a hammer. If the customer compares your quote to one you sent them two years ago, it reads like a different business wrote it.

That's not a reason to stop using AI to quote, speed matters, on-site pricing wins jobs. It's a reason to stop usinggeneric AI to quote, and start using AI that's been trained on your own work.

Why generic AI sounds generic

Most AI quote generators (including ChatGPT wrappers, spreadsheet plugins, and one-prompt web tools) produce output based on a general-purpose language model with zero context about your business. The model was trained on the entire internet, which for UK trade pricing means a blend of forum threads, builder FAQs, old Checkatrade guides, and a lot of American data that doesn't apply here.

The result is a quote that:

• Prices materials at averaged figures, not the rates you actually pay
• Uses generic line-item categories that don't match how you group work
• Adds disclaimers you'd never write in your own words
• Reads the same whether you're a sole-trader plumber in Sheffield or a five-man building firm in Surrey

None of which is a deal-breaker on a single quote. It becomes a deal-breaker when a customer has two of your quotes side by side and they read differently, or when they're comparing you to a competitor whose quotes sound identical to yours. Commoditised output gets commoditised prices.

What “trained on your quotes” actually means

The fix is retrieval. Instead of asking the AI to generate from its general training, you feed it examples of your own past quotes and ask it to mirror them. Your real pricing patterns, your actual phrasing, your specific line items, your typical payment terms, the way you describe a bathroom refit vs. the way the internet describes one.

That's what Quote DNA does inside QuickPrice. You upload up to 5 of your past quotes as PDFs or photos, the backend extracts structure, style, and conventions into a private profile, and every new AI-generated quote is shaped by that profile before it reaches you for review. The quote still uses current UK material costs and regional labour rates, the pricing is fresh. But the voice and structureare yours.

What you should upload

A few tactical notes on getting useful output:

• Upload quotes you sent, not blank templates.The AI is learning how you price real work, including the adjustments you make after the template runs.
• Mix job sizes. A repair call-out, a typical mid-range job, and one of your bigger projects gives the model better coverage than three versions of the same job.
• Include a quote where you did something unusual.Non-standard payment terms, supply-only discounts, a warranty clause you add by hand: these are exactly the patterns the model would never guess without examples.
• Skip quotes that went badly. If a quote got the job but you undercharged, don't train the AI to repeat that mistake.

Where it earns its keep

Quote DNA isn't magic for one-off jobs, the AI has always been decent at generating a one-off quote. It earns its keep for tradespeople who quote repeatedly:

• Boiler swaps and heating upgrades. Heating engineers have a specific way of structuring flue runs, controls, commissioning, and warranty. See quoting software for heating engineers.
• Bathroom refits. Bathroom fitters typically group work by stage (strip-out, first fix, tiling, second fix, commissioning). The AI matches your grouping once it's seen three of your past fits. See quoting software for bathroom fitters.
• Extensions and loft conversions. Builders often quote in phases with stage payments; without DNA the AI tends to lump everything into one total. See quoting software for builders.

What it doesn't do

Quote DNA doesn't copy old prices into new quotes, that would be a problem the first time materials went up 12%. It learns yourstyle and your structure and applies current UK pricing. It also isn't a substitute for reviewing the quote before you send, the AI still needs a human on the last mile to catch the odd weird line item, especially on unusual jobs.

And it won't help you if you haven't sent any quotes yet. If you're brand new to trading and still using scribbles-on-a-pad, use the generic AI output for a few months, then come back and train DNA once you've got a handful of real quotes to upload.

The short version

Generic AI output is a race to the bottom. Customers start spotting the sameness, and price becomes the only differentiator. The tradespeople winning on quality rather than on price will be the ones whose AI output reads like their own business, consistent, specific, recognisable. That's what Quote DNA is for, and it's included in the Pro plan at £12.99/mo + VAT with a 21-day free trial, no card required.
