Every tradesperson has a job like this somewhere in their history: it looked straightforward on the phone, took twice as long as expected, and by the time it was finished you worked out you'd barely covered your costs. Underquoting isn't a sign you're bad at your trade. It's a sign the way most of us price jobs is broken.
Why underquoting happens so often
Most quotes get written in one of two places: standing in the customer's kitchen with them waiting for an answer, or at home in the evening, tired, trying to remember the details of a job you looked at hours earlier. Neither is a good environment for accurate pricing.
On top of that, there are costs that are easy to forget entirely when you're focused on labour and materials:
- Skip hire and waste disposal
- Parking charges and congestion zones
- Fuel and travel time between jobs
- Scaffolding or access equipment
- Contingency for the unexpected — the "while you're here" extras
Miss two or three of these on a job and your margin can disappear before you've even started work.
The real cost of getting it wrong
An underquoted job doesn't just cost you money on that one job. It sets a precedent — the same customer may expect similar pricing next time, and you've got no paper trail to justify charging more if the job changes. Chase enough underquoted jobs and you can end up working full weeks that barely cover your outgoings.
How to actually stop it
The fix isn't "be more careful" — everyone's already trying to be careful. The fix is building a process that catches mistakes before you send the quote, not after:
- Price the job away from the pressure of the moment. Take photos and notes on site, then price it properly later rather than committing to a number on the spot.
- Use a forgotten-costs checklist every time. Skip, parking, fuel, contingency — build it into your process so it's never left to memory.
- Get a second opinion on your estimate. Whether that's a more experienced tradesperson or a tool that flags when your day estimate looks light for the job described.
- Put everything in writing — including variations. If the job changes on site, get it signed off there and then, not remembered later at invoice time.
This is exactly the gap ProfitQuote was built to close. When you describe a job, it checks your estimate against the complexity of the work and warns you if your pricing looks too low — before the quote goes out, not after the job's finished and the damage is done.
Common questions about underquoting
What does it mean when a job is underquoted?
A job is underquoted when the price agreed doesn't cover the real cost of labour, materials, and time — usually because costs like waste disposal, travel, or contingency were missed at pricing stage, not because the work itself was priced badly on purpose.
How do I stop underquoting jobs?
Price away from the pressure of the moment, use a forgotten-costs checklist every time, and get a second check on your number before it goes to the customer — ProfitQuote does this last step automatically.
