The customer takes the quote. The job goes in the diary. All good. Then you finish. The materials cost more. The work took longer. Two extra tasks turned up along the way. The customer is pleased. Your profit is not there.

That is underquoting: a job that works for the customer and not for you.

Why it happens

Tradespeople do not underquote because they cannot do the work. They underquote because pricing is a different skill.

To price a job you have to know how long it will really take, what the materials will really cost, what might go wrong, and whether the price leaves you enough.

Get any one of those slightly wrong and the money goes.

The four reasons

1. The time

Time costs more than anything else in a trade business. Quote two days, but spend four days doing it, and the profit is gone before you pick up a tool.

Most quotes price the perfect version of the job. Price the real one: setting up, driving, fetching materials, clearing up, and the hold-ups.

The job is not the task. It is everything the task needs.

2. The small costs

You remember the materials and the labour. The rest slips past: extra parts, a second trip to the merchant, fuel, parking, hire, subbies.

None of them looks like much. Add them up across a year and they are.

3. Memory

Instinct is built on real jobs, but it does not keep the figures. You remember the job was hard. You do not remember that it ran hours over, or cost you more in materials than you allowed, or barely paid at all.

Your finished jobs hold the answer. Most tradespeople never go back and look.

4. No room to move

Plans change. Something is hidden behind the wall. The customer asks for one more thing. The part is out of stock.

A quote that only works when everything goes right is not a quote. It is a hope.

What to do about it

Set the quote against the finished job

This is the one that changes things. Compare estimated hours with the hours you worked, estimated materials with the materials you bought, expected profit with the profit you kept.

That sum is worked through line by line in How Do I Know If My Jobs Are Actually Profitable?

Do that a few times and you can see where your pricing is sound and where it is not.

Price the whole job

Not just the work. The planning, the driving, the materials run, the setting up, the finishing, the call-back three weeks later.

Build in a buffer

You cannot predict every surprise, so price for the fact that surprises come. A buffer is not padding. It is the part of the quote that pays for the hidden problem, the second merchant trip, the half-day you did not plan.

Building the whole price from the ground up — costs, days, overheads, then the profit you want — is covered in How to Price Jobs Without Losing Money.

Let your own history set the price

If bathrooms always take you a day longer than you quote, quote the extra day. Your experience is worth more when it has figures behind it.

How Nule helps

Nule shows you what happened after the quote became a job.

You price the work with materials, outside costs and buffers. The customer accepts, and the quote turns into a live job on its own. So the estimate is still sitting there to measure against when the work is done.

Set side by side: what you quoted, what the materials cost, how long it took, and the profit left at the end.

End Job Insights show how one job went. Business Insights show the pattern across all of them:

  • which jobs lose you money
  • where you price the same kind of work too low
  • materials against your estimates
  • hours against the time you allowed
  • where the expenses actually go

Better quotes come from better information

Nobody prices every job perfectly. No quote survives every surprise.

The point is to know your own business well enough that each quote is closer than the last.

Every job you finish tells you something. Use it.

Winning work only counts if the work is worth having.
