Most trade businesses quote in a spreadsheet, and for good reason: it's free, it's familiar, and it works. So this isn't a "spreadsheets are bad" article — it's an honest look at where the spreadsheet holds up, and where it quietly costs you work.
Where the spreadsheet is genuinely fine
- You quote occasionally and know your numbers cold.
- Your jobs are simple and repeatable.
- You're happy doing the quote later, at your desk.
If that's you, a good template beats bad software every time. Don't fix what isn't broken.
Where it quietly costs you
The spreadsheet's weaknesses aren't about maths — they're about speed, trust and follow-through:
| Job to be done | Spreadsheet | Dedicated quoting software |
|---|---|---|
| Quote on-site, in minutes | Hard — usually done later at home | Built for it (photo → price) |
| Show the finished result | Not really | Visual render the customer reacts to |
| Prices reflect reality | Manual, goes stale | Live supplier prices on the line |
| Get a signature on-site | No | Sign on the device |
| Nothing gets forgotten | Depends on your memory | Quote becomes a tracked job |
| Consistent every time | Only if you're disciplined | Structure enforces it |
The single biggest gap is time-to-quote. A spreadsheet quote almost always happens after the visit — and every day it's late is a day a competitor can land theirs first (the research on why that matters).
The honest trade-offs
Software isn't free and it isn't magic. It costs a subscription, it takes a little learning, and if your jobs are dead simple it may be more than you need. The question isn't "which is better" in the abstract — it's "what does an hour of your evening, and one extra won job a month, cost you?"
For a solo tradesperson doing a handful of simple quotes, the spreadsheet wins on cost. For anyone quoting regularly, on-site, in a competitive market, the maths usually flips: the tool pays for itself the first time you close on the customer's kitchen table instead of emailing a PDF next week.
That's the specific gap Mastro is built for — quoting visually, on-site, in about five minutes — but the point of this post isn't the pitch. It's the question: is your quoting process actually winning you the jobs, or just recording the ones you'd have won anyway?
