The intake form is the first thing many prospective clients actually do with your firm. It sits between interest and engagement, and a poor one loses enquiries quietly: people abandon it, answer carelessly or never finish. A good one gathers what you need, feels easy and starts the relationship well.

This guide explains how to design a client intake form that converts, with fields to include for law, accounting and consulting firms, design principles, privacy considerations and common mistakes.

What is a client intake form?

A client intake form is the structured questionnaire a prospective or new client completes to give a firm the information it needs to assess the enquiry, check for conflicts or suitability, and begin work. It may be a short enquiry form on your website or a fuller onboarding form after the first conversation.

Two stages: enquiry form and onboarding form

What fields should an enquiry form include?

• Name.
• Email and phone, with a preferred contact method.
• A short description of what they need.
• Type of matter or service, as a simple choice.
• Urgency or key dates.
• How they heard about you, optional.

That is usually enough. Every additional field reduces completion. Do not ask for sensitive details at this stage, and tell visitors not to include confidential information in free-text boxes unless your process is designed for it.

What fields suit different firms at onboarding?

Collect what you need and no more. Over-collecting creates data protection obligations and risks without adding value.

Design principles for a form that converts

1. Ask for the minimum at each stage.
2. Group related questions and break long forms into short steps with a progress indicator.
3. Use choices instead of typing wherever possible.
4. Show only relevant questions. Use conditional logic to hide the rest.
5. Explain why you are asking for anything sensitive.
6. Make it work well on a phone, where many people will complete it.
7. Use clear, friendly labels and helpful error messages.
8. Allow saving and returning for longer forms.
9. Confirm instantly and say what happens next and when.

What privacy and security points matter?

• A short, clear privacy notice linked from the form, explaining what you collect, why and how long you keep it.
• Consent where your rules require it, recorded with the submission.
• Secure transmission and storage, with access limited to those who need it.
• A warning not to share sensitive details in open text fields, where appropriate.
• Spam protection that does not frustrate real users.
• Retention and deletion rules for enquiries that do not proceed.

See our security guide and, if you serve UK or EU clients, the basics of data protection law. This is general information, not legal advice.

What should happen after submission?

1. An instant confirmation on screen and by email.
2. Automatic routing to the right person.
3. A reply within a promised time. Speed often wins the work.
4. A booking link, if appropriate.
5. The record created in your system, not left in an inbox.

What mistakes should you avoid?

• Asking for everything up front.
• Mandatory fields that are not needed.
• Long free-text boxes with no guidance.
• No confirmation, so people wonder whether it worked.
• A form that breaks on mobile.
• Slow or no reply.
• Forms that are disconnected from your records, so staff retype everything.

How does the intake form connect to the rest of the process?

The form should be the start of a smooth flow: enquiry, qualification, engagement letter, document collection and file setup, with each step triggering the next. See what to cut before you build and our Discovery Sprint ($345, delivered in 24 hours, credited toward a build starting at $3,500).

Frequently asked questions

What should a client intake form include?

For an enquiry: name, contact details, a short description of the need, service type and urgency. For onboarding, the fuller information your work requires.

How long should an intake form be?

As short as possible at each stage. An enquiry form should take about a minute. Onboarding forms can be longer if guided and saved progressively.

Should I collect sensitive information in the first form?

Generally no. Keep the first form light and collect sensitive information later, through a secure channel, once the client has engaged.

How do I increase form completion?

Reduce fields, use choices, make it mobile-friendly, explain why you ask and confirm clearly.

What happens to enquiries that do not proceed?

Set a retention period and delete or anonymise them, in line with your policy and legal obligations.
