When most trade business owners set up their quoting system, they reach for Excel or Google Sheets. It's familiar, it's flexible, and it costs nothing — or so it seems. But when you take a hard look at what spreadsheet quoting is actually costing your business, the picture changes.
Building a quote in a spreadsheet — even from a decent template — takes time. You're manually entering line items, updating material prices, calculating subtotals, applying VAT, formatting the layout. If a quote takes 45 minutes instead of 15, that's 30 minutes lost. Do that five times a week and you've burned over two hours of your time — or a member of staff's time — that could have gone on billable work.
For a sole trader billing £50/hour, that's £100 a week, £5,200 a year. For a team with multiple estimators, multiply it out. "Free" software is rarely free.
Spreadsheets are only as accurate as the person filling them in. A broken formula, a missed row, a copy-paste from last month's job with the wrong materials — these are not hypothetical. They're the daily reality of spreadsheet quoting. And unlike a dedicated quoting system, a spreadsheet won't flag when something looks off.
The consequences range from mildly embarrassing (sending a quote with the wrong client name) to genuinely costly (underquoting a job because a labour row was accidentally deleted). One bad quote on a big job can wipe out months of margin.
Clients ask for revisions. Scope changes. Materials go up in price. With spreadsheets, every revision means a new file, or worse, overwriting the original. How many times have you sent "Quote_v3_FINAL_revised.xlsx" and still not been sure which version the client had approved?
This isn't just a nuisance. In a dispute, the inability to show a clear quote trail can be genuinely damaging. A proper system with versioned quotes and an audit trail is a business protection asset, not a luxury.
Purpose-built quoting software for tradespeople typically costs £20–£50 per month. At the lower end, if it saves you just one hour per week in quoting time, it pays for itself immediately. If it prevents one underpriced job per quarter on a typical £3,000 job, the maths become overwhelming in its favour.
The question isn't whether you can afford to switch. It's whether you can afford to keep doing it the slow, error-prone way.
Spreadsheets served their purpose when the alternative was pen and paper. But trade businesses are running proper operations now — and they deserve tools built for the job. If your quoting process still runs through a spreadsheet, there's a significant amount of money sitting in that inefficiency that belongs in your pocket.
