Intake Forms: What They Are and How to Build One

An intake form is a structured set of questions that collects everything you need from a new client before work begins — contact details, project scope, budget, timeline, and any assets or credentials required to start. For service businesses, it replaces the back-and-forth of emails and discovery calls with a single submission the client completes on their own time. Two out of three people who start a well-structured form finish it, according to Zuko Analytics. That rate depends on asking the right questions in the right order.

Intake forms are one step in the full client onboarding process, but they are the step that determines whether onboarding takes three days or three weeks. The right client intake software turns a static form into a workflow that triggers the next onboarding step automatically.

What Is an Intake Form?

An intake form is a questionnaire sent to new clients that captures the structured, factual information a service business needs before starting work. It covers contact details, business background, service requirements, budget, timeline, and any files or access credentials the team needs on day one. Unlike a discovery call — which works best for strategic discussion and relationship building — an intake form handles the repeatable questions that are the same for every client.

The term comes from medical and legal practices, where standardized intake paperwork has been used for decades. In service businesses — agencies, bookkeeping firms, consultants, coaches — it serves the same purpose: capture baseline information in a consistent format before work begins. HubSpot's guide to client intake forms identifies seven core areas a form should address, which we've consolidated into the five sections below.

The Five Sections Every Client Intake Form Needs

Every client intake form needs five categories of information regardless of industry. The specific questions change — a bookkeeper asks for tax IDs while an agency asks for brand guidelines — but the framework is universal.

1. Contact and business details. Name, email, phone, company name, role, and website. This takes the client under two minutes. Include a "preferred contact method" field — clients who respond to Slack in minutes may ignore email for days.

2. Service-specific questions. What the client needs, what they've tried before, and what success looks like. These questions differ the most by industry and should use conditional logic to show relevant follow-ups. An agency asks about target audience and competitors. A bookkeeper asks about accounting software and fiscal year end. Keep this to 3-5 questions.

3. Logistics — budget, timeline, and decisions. Budget range (use ranges, not exact amounts — ranges reduce abandonment), preferred start date, hard deadlines, and who else is involved in approving the engagement. The budget question is where most businesses lose nerve and skip it. Don't. Knowing a prospect's budget range before the first call saves both parties time when expectations do not align.

4. Assets and access. Logins, brand files, prior work, and credentials for tools you'll use. This section should include file upload fields — not "please email these separately," which creates a second workflow and doubles your follow-up. For guidance on structuring the document collection portion, see our guide on how to collect documents from clients.

5. Legal. Agreement to terms of service, consent for data handling, and any industry-specific disclosures. This section turns the intake form into a binding step in your onboarding checklist. When a client submits the form, they've agreed to your terms — no separate signature step needed if the form is designed correctly.

Intake Form Questions by Industry

The five-section framework stays the same across industries. The questions inside each section change based on what information actually blocks work from starting. For ready-to-use templates with every question listed, see our client intake form templates by industry. A bookkeeper who does not collect the accounting software login on day one loses three days chasing it later. An agency that skips the competitor question wastes the first strategy call discovering what a form could have captured in 30 seconds.

The table below shows the questions that differ most by industry. Contact details and legal sections are nearly identical across verticals and are excluded.

Marketing Agency

The question most agency intake forms miss: "What does success look like in 6 months?" If the client says "more phone calls" and your team measures brand impressions, you'll discover the misalignment three months into the engagement — after delivering work the client does not value. A single open-text question surfaces this before the first invoice. For the full agency onboarding sequence from SOW to first milestone, see client onboarding for agencies.

Bookkeeping and Accounting Firm

Accounting intake forms need system access captured during intake, not after. The accounting software login and bank connections are what block the first month of work. Ask which software they use (QuickBooks Online, Xero, FreshBooks, Wave), how many bank and credit card accounts the business has, and whether they have a separate business bank account. That last question identifies clients who mix personal and business finances — a scope-changing detail that affects every monthly reconciliation.

Law Firm

Legal intake has a requirement other industries do not: the conflict check. You need the opposing party's name and any related entities before you can accept the matter. Clio's client intake resources emphasize capturing conflict check data and signing the engagement letter during intake rather than in a separate step. Ask for the matter type, opposing party, any existing court dates with exact dates (not "soon"), and whether the client has worked with another attorney on this matter.

Coaching and Consulting Practice

Coaching intake forms lean heavier on goals and self-assessment because there are rarely logins or documents to collect. The key question: "What have you already tried?" This prevents coaches from spending the first three sessions rediscovering approaches the client has abandoned. A second question worth including: "On a scale of 1-10, how committed are you to making changes in the next 90 days?" Clients who answer below 6 rarely complete multi-session programs — the question screens for readiness without being confrontational.

How to Use Conditional Logic in Intake Forms

Conditional logic — showing or hiding questions based on previous answers — is what separates a professional intake form from a Google Form with 25 questions visible at once. It keeps the form short for straightforward clients (a solo consultant hiring you for bookkeeping sees 8 questions) while capturing full detail from complex ones (a 15-employee company with multiple entities sees 14). Both clients fill out the same form. They see different branches.

Three places where conditional logic has the most impact:

Service selection → service-specific follow-ups. When a client selects "Paid Ads," show questions about ad budget, current platforms, and conversion tracking. When they select "Brand Strategy," show questions about positioning, competitors, and target audience. Clients who select multiple services see all relevant follow-ups.

Existing assets → upload fields. "Do you have existing brand guidelines?" If yes → show a file upload field. If no → skip it and ask "Do you have a logo file?" This avoids blank upload prompts that confuse clients who have nothing to submit.

Company size → complexity questions. A freelancer does not need payroll or multi-entity questions. Use "How many employees does your business have?" as a branch point. Under 5: skip payroll. 5-20: show payroll questions. 20+: show payroll, entity structure, and compliance questions.

Worked Example: Agency Intake Form Template

Here's an intake form template for a marketing agency with three conditional branches. A client hiring for SEO only sees 9 questions. A client hiring for multiple services with existing brand assets sees all 12.

1. Company name (text field)
2. Your name and role (text field)
3. Email and phone number (text fields)
4. Company website URL (text field)
5. Which services are you interested in? (multi-select: SEO, PPC, Content Marketing, Social Media, Web Design, Branding)
   • → If "PPC" selected: What is your current monthly ad spend? (dropdown: Under $5k / $5k-$15k / $15k-$50k / $50k+)
   • → If "Web Design" selected: Redesign of an existing site, or new build? (radio buttons)
6. Who is your ideal customer? (text, 2-3 sentences)
7. Name your top 3 competitors (text field)
8. Do you have brand guidelines? (yes / no)
   • → If yes: Upload your brand guidelines (file upload)
   • → If no: Upload your logo, if you have one (file upload, marked optional)
9. What does success look like in 6 months? (text field)
10. Monthly retainer budget range (dropdown: Under $3k / $3k-$7k / $7k-$15k / $15k+)
11. When would you like to start? (date picker)
12. I agree to the terms of service (checkbox with link to terms)

A typical client finishes this form in 10-12 minutes. The conditional branches add 1-3 questions for clients with complex needs without adding friction for those with simple ones.

How Long Should Your Intake Form Be?

Eight to fifteen questions is the right range for most service businesses. Fewer than 8 and you'll end up on a follow-up call gathering information the form was supposed to capture — defeating its purpose. More than 15 and completion rates decline as clients abandon mid-form or rush through with half the fields blank.

The data supports this range. According to Zuko Analytics, 66% of people who start a form complete it — but that average spans all form types and lengths. Typeform's platform data shows average completion rates between 47% and 57%, with the gap driven by form design and question quality. Intake forms from warm prospects — people who have already agreed to work with you — should outperform these averages, since the client is motivated to start.

The practical test is simpler than any benchmark: fill out your own form as a client. Time yourself. If it takes more than 15 minutes, or if any question makes you pause to figure out what it's asking, the form needs editing. Client onboarding software with built-in form builders lets you test and iterate without rebuilding from scratch each time.

Intake Form vs. Questionnaire

They're the same thing in practice — a structured set of questions sent to a client. The terminology varies by industry. "Intake form" is standard in legal, medical, and professional services, where it implies a formal step required before work begins. "Questionnaire" is more common in consulting, creative, and coaching work, where it implies information gathering.

The functional difference is about what happens after submission. An intake form is typically a one-time submission that includes legal agreements (terms of service, engagement letter) and triggers the next onboarding step — a task assignment, a calendar invite, or an automatic welcome email. A questionnaire can be recurring (quarterly business reviews, project kickoff briefs) and usually does not gate any workflow. If your form includes a terms-of-service checkbox and the submission kicks off a defined process, it's an intake form. If it's purely informational, it's a questionnaire.

Five Mistakes That Kill Intake Form Completion Rates

1. Asking for information you will not use. Every question should connect to a specific decision or action in your first week of work. "How did you hear about us?" does not change how you onboard the client. Cut it from the intake form, or move it to a separate post-signup survey.

2. Using your jargon instead of the client's language. "Describe your KPIs" makes sense to marketers. A plumbing company owner wants to say "get more calls." Write questions the way the client thinks, not the way your team talks internally.

3. Requiring long-form answers for everything. "Describe your business, target market, competitors, and 12-month growth plans" as one text field is a homework assignment. Break it into 3-4 specific, answerable questions. One question, one topic.

4. Showing every question to every client. Displaying 20 questions when most clients need 10 is the fastest way to trigger abandonment. A solo freelancer does not need questions about payroll processing, multi-entity consolidation, or org charts. Conditional logic fixes this.

5. Making the form a dead end. The client answers 12 questions, hits submit, and sees "Thanks, we'll be in touch." No timeline. No next step. No confirmation of what happens now. Your confirmation page should state what happens next, who will contact them, and when — "Your onboarding coordinator Sarah will email you within 24 hours with your project kickoff date" is specific enough to build confidence.

Frequently Asked Questions

What is an intake form?

An intake form is a structured questionnaire that collects the information you need from a new client before you begin work. For service businesses, this typically includes contact details, business information, project scope or service needs, budget and timeline expectations, and any assets or credentials you need to get started. A well-designed intake form replaces the back-and-forth of email-based information gathering, freeing discovery calls for strategic discussion instead of fact-finding.

What should I include in a client intake form?

Every client intake form needs five sections: (1) Contact and business details — name, email, company, role. (2) Service-specific questions — what they need, what they've tried before, what success looks like. (3) Logistics — budget range, preferred timeline, decision-making process. (4) Assets and access — logins, brand files, prior work, with file upload fields for each item. (5) Legal — agreement to terms, consent for data handling. Use conditional logic so different answers reveal different follow-up questions, keeping the form focused for each client type.

How do I create an intake form?

Start with the five-section framework: contact, service needs, logistics, assets, legal. Draft 8-15 questions total — forms that exceed 15 questions see declining completion rates as clients lose momentum or cannot answer without searching through files. Add conditional logic for branching: "Do you have existing brand guidelines?" shows an upload field if yes, skips it if no. Then fill out the form yourself as if you were a client. Time yourself. If it takes more than 15 minutes or any question makes you pause, rewrite that question.

What is the difference between an intake form and a questionnaire?

They're the same thing in practice — a structured set of questions sent to a client. "Intake form" is more common in legal, medical, and professional services, where it implies a formal process required before work begins. "Questionnaire" is more common in consulting and creative work, implying ongoing information gathering. The functional difference: an intake form is typically a one-time, required submission that may include legal agreements and triggers the next onboarding step, while a questionnaire can be optional, recurring, or purely informational.

How many questions should an intake form have?

Between 8 and 15 questions for most service businesses. Fewer than 8 and you will not gather enough information to begin work — you'll schedule follow-up calls that the intake form was supposed to replace. More than 15 and completion rates drop as clients abandon mid-form or rush through with low-quality answers. According to Zuko Analytics, two-thirds of people who start a well-structured form finish it, but that rate declines with length and poor question design. Use conditional logic to show additional questions only when relevant, keeping the visible count low for most clients.
