I Started Quoting Faster as a Handyman — Then I Built the App

Short answer

I’m a working handyman. I didn’t start SMASH because I loved “AI invoicing.” I started it because I needed estimates faster — and every shortcut I tried got the money wrong.

Now I send an on-site quote in about 30 seconds: talk the job, verify my prices, send the PDF before I leave. First clear number usually wins.

Product: Voice quote / invoice on iPhone. My story: Meet the founder.

The real problem wasn’t typing speed

I run Good Hands Handyman. I’m still on jobs. I’m also dyslexic — sitting down to type a neat quote after a long day was slow and painful. So I did what everyone does now: I looked at AI.

Paste the job into ChatGPT. Ask for a professional quote. It sounded great.

Then I checked the numbers.

Wrong hourly rate. Soft materials. Call-out fee missing. GST vibes instead of my GST. It was writing an essay about the job, not quoting my business.

That’s the trap: fast wording, wrong money.

Why “I’ll email a quote tonight” loses

On site, someone asks “how much?”

If I say I’ll send it later, I’m competing with whoever already answered. I learned that the hard way. The first priced document in their hand wins more often than the perfect one that never leaves the drafts folder.

That’s why I care about first quote wins — instant quote on site more than another template pack.

What I built instead

I didn’t want a chatbot that invents prices. I wanted:

1. My rates and materials in the background — a catalog that remembers what I charge
2. A verify step — unmatched items flagged, not silently guessed
3. Voice on top — because talking is how I already describe jobs to mates and customers

Voice without catalog is just dictation. Catalog without speed is still Sunday night. Together it’s talk → verify → send.

Same loop for invoices when the work is done: what is voice to invoice?.

The ~30-second on-site quote, the way I actually do it

1. Talk the scope — rooms, labour, fittings, call-out if it applies.
2. Glance the lines — quantities and prices from my list.
3. Send — branded PDF while I’m still in the driveway.

If they approve and I finish the job, I convert to invoice. I don’t rebuild it from memory at the kitchen table.

Desk requests in email? Different surface, same idea: Gmail invoice.

If you’re already pasting jobs into ChatGPT

You’re not lazy. You’re trying to move faster. I did the same thing.

Just know what ChatGPT is good at (wording) and what it isn’t (your catalog, sendable tax docs, payment). Longer take: Can ChatGPT write a quote or estimate? and Can ChatGPT generate invoices?.

Bottom line

I built SMASH for me — a handyman who needed estimates quicker without wrong prices. Voice is the accelerator. The catalog is the truth.
