What is a lead capture form?

What makes a form a lead form

Two things: an exchange and a set of qualifiers. The exchange is what the person gets for their details, such as a written quote, a product demonstration, a pricing estimate or a report, and it has to be worth more to them than the effort of the form. The qualifiers are the handful of questions that tell the business what to do next. Most come down to four: what the person needs, how big the job is, when they want to act and who makes the decision. A form without an exchange feels like a toll booth, and a form without qualifiers produces a list of names that sales has to phone blind. Qualifiers also help the person filling in the form, because a question about budget or timing signals that the reply will be specific to them rather than a generic brochure. Write each one so the answer changes what happens next; a qualifier whose answer nobody acts on is just another field.

The length trade

Every question removes some people and sharpens the picture of those who remain. A three field form collects the most submissions and tells you almost nothing. A fifteen question form collects far fewer, mostly from people serious enough to push through. Usability research on forms has long recommended cutting every field that is not needed, and lead forms are where that advice bites hardest. The workable middle is contact details plus three to five qualifiers asked as quick choices rather than open boxes, with one optional free text question at the end for anything the choices missed. Ask the most useful qualifier first, so the top of every response tells sales something at a glance.

Consent and follow up

A person who asks for a quote expects to hear about that quote. Marketing beyond it is a separate matter. In Australia the Spam Act requires consent before marketing messages, and the regulator's guidance says express consent can be given by ticking a box on a form, that the sender must be able to prove it, and that every message needs a working unsubscribe honoured within 5 working days. The practical form design is a required choice for the thing they asked for, and a separate, optional, unticked line for anything else. The consent checkbox page covers the wording and the rules in other countries.

Mistakes that cost leads

Asking for a phone number when nobody intends to call. Requiring a job title typed as free text, which produces a hundred spellings of manager. Promising a reply without saying when, so the lead goes cold while they wait. Making marketing email a condition of getting the quote. Fields that cannot be filled automatically: accessibility guidance asks that inputs collecting a person's own details declare their purpose, which also lets browsers autofill name and email and saves the most tedious typing on a phone. And a form that asks qualifying questions but routes every answer to the same inbox, where nobody acts on the difference.

Building one in this form builder

The lead capture example is a conversational form of nine questions: three contact details, four qualifying choices on building type, quarterly electricity spend, timing and who signs off, one optional open question about why now, and a final required choice where the written indication and an optional marketing line are separate options. Its welcome screen states the time and the reply window. The webhook add-on posts each submission once as JSON, with data keyed by field label and raw data keyed by field id, which suits a CRM, and there is no retry. The redirect add-on can send people to a booking page straight after submitting. There are no hidden fields, so campaign source is asked as a question or kept apart with a separate form per campaign.
