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. It replaces the email thread and the discovery call with one submission the client fills out whenever they want. Two out of three people who start a well-structured form finish it, according to Zuko Analytics. That rate holds only if you ask the right questions in the right order.
Intake forms are one step in the full client onboarding process. They are the step that decides whether onboarding takes three days or three weeks. Good client intake software turns the static form into a workflow that fires the next step by itself. For ready-to-use templates by industry, see client intake form templates and examples.
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 the files or logins the team needs on day one. A discovery call is for strategy and for getting to know each other. The form takes the questions you ask every client anyway.
The term comes from doctors and lawyers, who have run standardized intake paperwork for decades, traditionally a printable client intake form PDF. Agencies, bookkeeping firms, consultants and coaches use it for the same job: get the baseline facts in one shape before work starts. HubSpot's guide to client intake forms identifies seven core areas a form should address, which we've consolidated into the five sections below.
An intake form is only as good as its structure. The difference between a form that clients complete in 10 minutes and one they abandon after 3 is not the number of questions. It is the order, the conditional logic, and whether each question earns its place. Target 8 to 15 questions organized into five sections (contact, service needs, logistics, assets, legal) with conditional branching so each client type sees only what applies to them.
The Five Sections Every Client Intake Form Needs
Every client intake form needs five categories of information regardless of industry. The questions change. A bookkeeper wants tax IDs, an agency wants brand guidelines. The frame underneath does not move.
1. Contact and business details. Name, email, phone, company name, role, and website. Under two minutes of the client's time. Include a "preferred contact method" field. The client who answers Slack instantly will sit on your email for days.
2. Service-specific questions. What the client needs, what they've tried before, and what success looks like. This is where industries diverge the most, so branch it with conditional logic. An agency asks about target audience and competitors. A bookkeeper asks about accounting software and fiscal year end. Keep this to 3 to 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. Do not. A budget range before the first call saves everyone the meeting where the numbers do not match.
4. Assets and access. Logins, brand files, prior work, and credentials for tools you'll use. Put real upload fields here. "Please email these separately" is how you end up running two workflows and chasing the same files twice. 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. Build it right and you never send a separate signature request.
Intake Form Questions by Industry
The five-section framework stays the same across industries. What changes inside them is whatever is blocking the 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 get the accounting software login on day one spends three days chasing it. An agency that skips the competitor question burns the first strategy call on what a form could have captured in 30 seconds.
The table below shows the questions that differ most by industry. Contact details and legal look nearly the same everywhere, so they are left out.
| Section | Marketing Agency | Bookkeeping Firm | Law Firm | Coaching Practice |
|---|---|---|---|---|
| Service needs | Services needed (SEO, PPC, content, design); target audience; top 3 competitors; marketing done in the past 12 months | Services needed (monthly bookkeeping, payroll, tax prep); accounting software; fiscal year end; number of employees | Matter type (business, family, estate, litigation); opposing party; prior legal representation; court deadlines | Primary goal; what they've tried before; biggest current obstacle; preferred session format |
| Assets and access | Google Analytics access, social media logins, brand guidelines, content library | Accounting software login, bank access, prior year tax returns, payroll provider credentials | Relevant contracts, correspondence, evidence, prior attorney contact info | Previous assessments, journal entries, relevant work documents |
| Budget and timeline | Monthly retainer range; ad spend budget; campaign start date | Monthly bookkeeping budget; expected transaction volume; tax filing deadlines | Retainer vs. hourly preference; budget range; statute of limitations dates | Session frequency; package preference; commitment length |
Marketing Agency
The question most agency intake forms miss: "What does success look like in 6 months?" The client says "more phone calls." Your team reports brand impressions. Nobody catches it for three months, and by then you have delivered work the client does not value. One open-text box 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. Without the accounting software login and the bank connections, the first month does not start. 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 one finds the clients who run personal and business money through one account. It changes the scope of every monthly reconciliation.
Law Firm
Legal intake has a requirement other industries do not: the conflict check. You cannot accept the matter until you have the opposing party's name and every related entity. 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?" Skip it and you spend the first three sessions rediscovering approaches the client has already 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. It screens for readiness without sounding like an interrogation.
How to Use Conditional Logic in Intake Forms
Conditional logic (showing or hiding questions based on previous answers, via conditional logic) is what separates a professional intake form from a Google Form with 25 questions visible at once. A solo consultant hiring you for bookkeeping sees 8 questions. A 15-employee company with multiple entities sees 14, and you get the full picture from both. Same form. 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?" Nobody should stare at an upload box for a file they do not have.
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 to 20: show payroll questions. 20+: show payroll, entity structure, and compliance questions.
Conditional logic keeps intake forms short by showing follow-up questions only when they're relevant to that specific client. Three high-impact branches: (1) service selection triggers service-specific questions, (2) "Do you have X?" triggers an upload field or skips it, and (3) company size triggers complexity-appropriate questions. A 15-question form with conditional logic feels like 8 questions to a simple client. Portico's intake forms support this branching natively, with file uploads and automatic triggers that start the next onboarding step when the form is submitted.
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.
- Company name (text field)
- Your name and role (text field)
- Email and phone number (text fields)
- Company website URL (text field)
- 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)
- Who is your ideal customer? (text, 2 to 3 sentences)
- Name your top 3 competitors (text field)
- 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)
- What does success look like in 6 months? (text field)
- Monthly retainer budget range (dropdown: Under $3k / $3k-$7k / $7k-$15k / $15k+)
- When would you like to start? (date picker)
- I agree to the terms of service (checkbox with link to terms)
A typical client finishes this form in 10 to 12 minutes. The branches add 1 to 3 questions for the complicated clients and cost the simple ones nothing.
How Long Should Your Intake Form Be?
Eight to fifteen questions is the right range for most service businesses. Fewer than 8 and you book a follow-up call to collect what the form was supposed to collect. More than 15 and completion rates decline: people quit halfway, or hammer 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. Your intake form goes to warm prospects who already agreed to work with you, so it should beat those averages.
The practical test is simpler than any benchmark: fill out your own form as a client. Time yourself. Over 15 minutes, or one question that makes you stop and decode it, and the form needs editing. Client onboarding software with built-in form builders lets you fix it and test again without starting over.
Target 8 to 15 questions for your client intake form. Use conditional logic to keep the visible count at 8 to 10 for straightforward clients while capturing 12 to 15 data points from complex engagements. Zuko Analytics data shows two-thirds of form starters complete the process, and Typeform reports average completion rates of 47% to 57% across their platform. The number of questions matters less than their relevance. A focused 12-question form outperforms a padded 8-question form that asks things the client cannot answer without digging through files.
Intake Form vs. Questionnaire
They are the same thing in practice: a structured set of questions sent to a client. Only the word changes, and it changes 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 real difference shows up after the client hits submit. 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 the question in the client's words, not the ones your team uses 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 to 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.
The two highest-impact changes to an existing intake form: add conditional logic to hide questions that do not apply to each client, and replace the generic "Thanks" confirmation with a specific next step and timeline. Both changes take under an hour to implement. The first reduces friction for every client who does not fit your most complex profile. The second replaces post-submission anxiety with confidence that the engagement is moving forward.
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 to 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 are 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 will 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.
