How AI voice quoting works for tradespeople

You speak a job description into your phone and receive a fully priced professional quote in under 10 seconds. But how does that actually work? Here's a plain-English explanation of what's happening behind the scenes — no technical knowledge required.

The short version

When you hold the mic in Zipflow and describe a job, four things happen in rapid sequence: your voice is converted to text, the AI reads that text and identifies every trade task implied by the description, your saved rates are applied to each task, and a formatted professional quote is assembled. The whole process takes under 10 seconds.

What makes it useful isn't the technology — it's the fact that the AI understands trade language specifically. It knows that "fit a new consumer unit" implies certain tasks, materials and labour. It knows the difference between a combi boiler and a system boiler. It knows to ask about access and disposal. Generic AI can't do this — it requires a system trained specifically on trade work.

Step by step — what happens when you speak a job

1

Speech to text

Your voice is captured and converted to text using speech recognition. Zipflow uses recognition tuned for UK accents and trade terminology — it understands "RCBO", "TRV", "RSJ" and other trade-specific terms that general voice recognition often misinterprets.

2

Trade detection

The AI reads the transcribed text and identifies which trade is involved — electrician, plumber, builder, painter, and so on. This happens automatically. If multiple trades are involved in one job, all of them are detected.

3

Task identification — 912 job types

This is where Zipflow's trade-specific training matters most. The AI maps your description against over 912 specific task types across 10 trades, identifying every piece of work implied by what you said — including tasks you may not have explicitly mentioned but which are necessarily part of the job.

Refinement questions

For each task identified, the AI asks any follow-up questions needed to price accurately — room size, material specification, access difficulty, number of units. These are trade-specific questions, not generic ones. You tap your answers in seconds.

Quote generation

Your rates, markup and material costs are applied to each identified task. A fully itemised quote is assembled with labour, materials and total. Your business details are added. The document is formatted professionally and ready to send.

~3 seconds

Send to customer

You review the quote — takes about 30 seconds — then send it directly via email or WhatsApp. The customer receives a professional quote link on their phone.

What the AI actually understands

The most common question tradespeople ask about AI quoting is whether it actually understands their work or just does keyword matching. The honest answer is that Zipflow's detection engine is built around deep trade knowledge — it's not just looking for the word "boiler" and returning a generic boiler price.

When you say "fit a new combi boiler", the system understands this implies: removal of the existing boiler, disconnection from existing pipework, installation of new unit, connection to gas supply, connection to heating circuit, connection to hot water system, commissioning, pressure testing, and registration — among other elements. It asks clarifying questions about flue type, location, brand preference, and whether it's a like-for-like replacement or a system change.

Example voice input
"Replace the existing combi with a Worcester Bosch 30i, same location, new flue, powerflush the system while we're there"

From that single sentence, Zipflow identifies: boiler replacement, flue installation, powerflush, and asks about system size, access, and whether a new programmer is needed. The quote it generates covers every task implied by the description — not just the ones explicitly mentioned.

How pricing accuracy works

A common concern with AI quoting is accuracy — specifically, whether the prices it generates reflect real UK trade rates. The answer is that Zipflow's pricing is based on your rates, not generic averages.

When you set up Zipflow, you enter your day rate, default markup, and any material costs you want to save. Every quote is generated using these values. The AI handles the task detection and itemisation — you supply the pricing. This means quotes are accurate for your business, in your area, at your current rates.

As you generate more quotes, Zipflow learns your preferences. If you consistently adjust a particular line item — say, you always quote boiler installations at a higher labour rate than your default — the system begins to reflect this in future quotes.

Important: AI quoting tools don't replace your trade knowledge — they apply it faster. The accuracy of a Zipflow quote depends on the quality of your voice description and the rates you've set. A detailed description produces a better quote. Your expertise is still the foundation; the AI just removes the admin of translating that expertise into a formatted document.

What happens when the AI gets something wrong

No AI system is perfect, and Zipflow is designed with this in mind. Before the quote is generated, you see exactly what the AI heard and what it understood. You can correct any misheard words and remove any tasks that aren't relevant. After the quote is generated, you can edit any line item, adjust any price, and add tasks manually before sending.

The review step takes under a minute for most quotes. Most tradespeople find that their voice quotes need minimal correction — partly because they're describing jobs they've just surveyed, while the details are fresh, and partly because the AI is designed to ask questions rather than guess when it's uncertain.

How AI quoting is different from a quoting template

A quoting template requires you to know in advance what tasks a job involves and enter them manually. AI quoting detects the tasks from your description. This difference is significant for two reasons.

First, speed. Manual entry into a template takes 30 to 90 minutes. AI detection and generation takes under 10 seconds.

Second, completeness. When you fill in a template, you include the tasks you consciously think of. When the AI processes your description, it includes all tasks implied by what you said — including ones that experienced tradespeople know belong to a job type but might not consciously include in a manual quote. The AI never forgets to quote for testing on an electrical job or disposal on a bathroom fit.

The role of trade-specific training

Generic AI — the kind that powers ChatGPT or standard voice assistants — can process natural language but doesn't have the domain knowledge needed to quote trade work accurately. Asking ChatGPT to generate a consumer unit quote would produce something plausible-sounding but commercially useless.

Zipflow's detection engine was built specifically around UK trade work. It was trained on real job descriptions from real tradespeople, refined against actual quote data, and tested across hundreds of specific job types. The 912 task types it detects aren't generic categories — they're specific jobs like "fit thermostatic shower valve", "replace ball valve in loft tank", or "install EV charger on existing supply".

This specificity is what makes the difference between a novelty and a tool that saves five hours a week.
