Quote forms: how many fields before people quit

Contractor quote forms grow the way junk drawers grow. Somebody adds "how did you hear about us." A CRM requires an email. Marketing wants preferred contact time. Nobody ever removes anything.

Two years later the form has eleven fields, and the homeowner standing in a garage on a cracked phone screen closes the tab.

Which fields do you actually need?

Four, and you can defend every one of them.

Name. Obvious.

Phone. This is how the job gets booked. Email is a slower phone number and it is where estimate requests go to be ignored.

Address or at least the town. Without it you cannot tell whether the job is even yours, and your first call is wasted on "where are you located."

What is wrong, in their words. One open box. Not a dropdown with sixteen trade terms a homeowner cannot map to their situation. "My water heater is leaking" tells your dispatcher everything a taxonomy would not.

Everything else is optional at best. Preferred appointment time belongs on the call, because you know your schedule and they do not. "How did you hear about us" is a question your tracking should answer, and homeowners answer it wrong anyway.

The test is not how many fields feel reasonable at a desk. It is whether somebody standing in a wet garage finishes it.

Is there research on the right number of fields?

Not for your form, and the honest answer is more useful than a borrowed number.

The best sourced work in this area is Baymard Institute's checkout research, which has tracked form design for more than a decade. Baymard reports that the average checkout flow in 2024 runs 5.1 steps and contains 11.3 form fields, that 17% of users have abandoned a purchase because checkout was too complicated, and that the step count has barely changed since they started tracking in 2012.

The load bearing finding is the one people skip. Baymard's position after ten years of testing is that the number of steps matters far less than the number of form fields users must consider. Splitting eleven fields across three friendly screens does not fix eleven fields.

Now the limitation, and it is a real one. That is ecommerce checkout research, not local business lead form research. It supports fewer fields as a directional principle. It does not tell you what a plumber's quote form should contain. No study with a disclosed sample and method exists for contractor lead forms, and anyone quoting you a field count benchmark for one is quoting something that was never measured.

So use the principle, then measure your own form. Which is the next section.

What does the arithmetic look like on a real form?

Why not collect more while you have their attention?

Because you do not have their attention. You have about forty seconds of it and you are spending it.

The reasoning contractors give is that a longer form filters out unserious people. That is true and it is the wrong trade. It filters out unserious people and a large share of serious ones, and you cannot see which is which, because the ones who quit leave no record.

If you want to filter, filter earlier and cheaper. Say clearly on the page which towns you serve, which jobs you take, and roughly what things cost. Housecall Pro's 2026 home services research found 68% of homeowners get additional quotes when pricing comes in higher than expected, so a page that refuses to discuss money is not preventing price shopping, it is postponing it until after you have driven out. The same survey found 72% would pay more to resolve an emergency within 24 hours, which tells you availability belongs on the page next to price.

Somebody who reads all of that and still submits is qualified. This is the same work that makes service area pages either useful or ignorable, and it is a far better filter than a long form.

On paid traffic, the filter belongs in the ad itself. Ad copy that filters out the wrong customers costs you nothing and screens people before you pay for the click.

Should I add a photo upload?

Yes, and make it optional.

A photo of the failed part is the single most valuable field on a contractor form. Your estimator can frequently price the job from it, which removes an entire phone call, and homeowners are willing because they are already holding the camera.

Optional matters. A required upload stops people who are at work describing a problem at home.

The same logic applies to any field you badly want but cannot justify as required. Make it optional and put it last. You will get it from maybe half of people, at no cost to the ones who quit.

The other thing worth adding is not a field. A line under the submit button saying what happens next and when. "We call back within one business hour, 7am to 6pm." That sentence does more for completion than any field you could remove, because it tells the homeowner they are starting a defined process rather than shouting into a void.

Can you test your way to the right form?

Almost certainly not at your traffic, and the number usually quoted for this is worth understanding.

The rule you will hear is that A/B testing needs around 10,000 monthly visitors. That figure is not a research finding. It traces to a 2013 blog post, where it surfaces as a citation inside Kohavi, Deng, Longbotham and Xu's peer reviewed KDD 2014 paper, and those four authors immediately add that the guidance should be refined to the metrics of interest. Their actual position is that minimum sample size is a function of the metric's variance and the size of the effect you want to detect, not a fixed traffic number. In their own worked table, one Bing metric needed 114,000 users per variant and another needed 4,700, depending on skew.

Derive yours instead. At 96 monthly submissions, splitting traffic two ways gives 48 per variant per month. The effects you are hunting are small: the same paper reports that at Bing, most experiments fail and those that succeed move key metrics by 0.1% to 1.0% once diluted. You would need many months at 48 per variant, by which point season, spend and offer have all changed.

And this is where the case studies come in, which is the part worth refusing. The most famous conversion result of the last fifteen years is that a red call to action button beat a green one. Kohavi and his coauthors name that specific result in their paper as their example of a finding that does not generalize, writing that since they do not see a lot of sites with red call to action buttons, they believe it is not a general result that replicates well. They invoke Twyman's law in the same paper: any figure that looks interesting or different is usually wrong.

So no red buttons because a case study said so, and no testing program sold to you at contractor traffic. What works instead is watching real people. Sit somebody down who has never seen your site, hand them a phone, and ask them to request a quote for a broken water heater. Two people will tell you more than a test you cannot run.

Where does this break down?

Three places.

When the form is not the constraint. If your page gets 300 visits a month, the form is downstream of a traffic and visibility problem, and a shorter form on nothing is still nothing.

When the shorter form outruns the phone. The 2011 Harvard Business Review audit of 2,241 US companies found 23% never responded to an inbound lead at all and 24% took more than a day. Cite it carefully: coauthor David Elkington founded the software company whose platform supplied the data, and HBR is a magazine rather than a peer reviewed journal. More submissions arriving into that pattern is more waste, faster.

When the leads route through automation. If an automated first response handles the form, know exactly where the handoff sits, because how good implementations escalate to a human is what separates a fast reply from a customer stuck in a loop.

What to do this week

Open your quote form on your own phone, one handed, and time yourself. Count the fields. Delete every one you cannot defend as necessary for the first phone call.

Pull the field level dropoff report and run the six step arithmetic above, ending at cost per booked job rather than submissions.

Add an optional photo upload. Add the sentence under the button telling people when you will call.

Then look at what your competition is doing with the same visitor. The national lead aggregators run four field forms because they have tested them at a volume you never will, and copying their form structure is one of the few places where competing with the aggregators means imitating rather than differentiating.

Last, check whether your form fits the jobs you actually want. A form built for emergency repairs will not serve somebody pricing a full system replacement, and getting found for the expensive job rather than the cheap one usually needs a different form with different questions.

Questions about your quote form?

Email me at eric@seod.com with a link to your form. I will fill it out from a phone, time it, count the fields, and send you back the two fields I would delete first and the one sentence I would add under the button. Straight answer in a day, no deck and no sequence.
