Quoting on site vs over the phone: pick per job, not per business

Introduction

Every trade business settles into one habit. Some quote everything over the phone to save time and then discover the job was twice the size described. Others insist on visiting everything and spend half the week driving to jobs that were never going to happen.

Both habits are expensive, and both come from treating this as one decision when it is really a decision per job type.

1. Quoting on site vs over the phone: the real cost of each mistake

A phone quote that turns out wrong costs you the margin on that job, plus an awkward conversation, plus the risk of a bad review when the price changes.

A site visit for a job you were never going to win costs an hour of travel, an hour on site, and the slot a paying job could have occupied. It is unpaid work that never appears in any account.

Neither is free. The question is which risk you can absorb on which kind of work.

2. Phone-quote what is genuinely standardised

Some tasks vary so little that a visit adds nothing: a like-for-like replacement of a known unit, an annual service, a standard test and certificate.

Build a price for each of these and let whoever answers the phone quote it directly. Booking on the first call converts far better than booking a visit to talk about booking work.

3. Visit anything where scope is the unknown

Anything where the answer depends on what is behind a wall, under a floor, or in an old installation should be seen.

Rewires, repipes, replacements in awkward locations, anything involving access, anything where the previous installer's decisions matter. These are the jobs where a phone estimate is a guess, and the guess is always low, because the customer describes the problem optimistically.

4. Qualify hard before you agree to drive

The site visit is your scarcest resource, so it should be earned.

Three questions on the phone: what is the scope, when do you need it, and is there a budget range in mind. Anyone unwilling to engage with all three is rarely ready to buy, and finding that out in four minutes is much cheaper than finding it out after ninety.

5. Give a range on the phone rather than a number

For anything you will not quote firmly by phone, a stated range is better than refusing to discuss price.

"Jobs like this usually land between X and Y depending on access, and I can confirm once I've seen it" respects the caller's need to know whether you are in their universe at all. Refusing to indicate anything loses the customer who is politely trying to avoid wasting your time and theirs.

6. Charge for the visit where the market allows

If site visits are consuming a day a week, price them.

A modest assessment fee, credited against the work if they proceed, filters out the tyre-kickers almost entirely while barely affecting serious buyers. Businesses that make this change usually report the same outcome: fewer visits, higher close rate, more revenue.

7. Quote on site, in writing, before you leave

If you have driven there, do not leave without giving the number.

Every day between the visit and the quote is a day the customer spends talking to someone else, and quotes sent later close markedly worse than quotes handed over on the spot. Bring a template, fill it in at the kitchen table, and leave a copy.

8. Write down what is excluded

Most quote disputes are not about the price agreed but about what the price was supposed to include.

Name the exclusions plainly — making good, redecoration, access issues, existing faults you have not been able to see — and state how variations will be priced. Customers who have been burned before find this reassuring rather than off-putting.

9. Track close rate separately for each method

Split the numbers: quotes given by phone versus on site, close rate and average value for each.

Almost every business discovers a boundary it had drawn in the wrong place — either visiting jobs that close fine by phone, or phone-quoting a category that consistently comes back under-priced. That single split is what turns this from an opinion into a policy.

Conclusion

Treat this as a decision per job type rather than a house rule. Phone-quote genuinely standardised work and book it on the first call; insist on seeing anything where the scope hides behind a wall.

Qualify with scope, timing and budget before agreeing to drive, give a range rather than refusing to discuss price, consider a credited assessment fee if visits are eating a day a week, hand the written quote over before you leave, name your exclusions and variation pricing, and split close rate by quoting method to find where your boundary is actually wrong.
