The client onboarding questionnaire: what to ask every new client
The client onboarding questionnaire every agency needs - the questions to ask each new client, grouped and ready to copy, so you gather everything once and start work faster.
Part of the client onboarding guide
One questionnaire beats ten "quick questions"
Without a structured intake, onboarding becomes a fortnight of scattered emails: a logo here, a login there, a "what's your deadline again?" three days in. Every missing piece delays the start and chips at the client's confidence that you've got this. A single, well-built onboarding questionnaire replaces all of that - you ask once, thoroughly, and start work with everything you need.
It also makes onboarding repeatable. The same questionnaire for every client means a consistent, professional start that a new team member can run without you, and a creative brief you can assemble from real answers instead of guesswork.
The questions to ask, grouped
Group your questions so the client can answer in one focused sitting. Five blocks cover most agencies:
CLIENT ONBOARDING QUESTIONNAIRE
1. THE BUSINESS
- What does your business do, in one sentence?
- Who are your customers?
- Who are your main competitors?
- What makes you different from them?
2. GOALS & SUCCESS
- What's the main outcome you want from this work?
- How will you measure success? (the metric)
- What's the deadline or driver behind it?
- What does "great" look like to you?
3. BRAND & ASSETS
- Brand guidelines, logos, fonts (links)
- Tone of voice - words you love / words you ban
- Examples you admire (and why)
- Anything off-limits?
4. LOGISTICS & ACCESS
- Who is our main point of contact?
- Who gives final sign-off?
- Tools/accounts we'll need access to
- Preferred channel & response expectations
5. CONTEXT
- What have you tried before? What worked / didn't?
- Any internal politics or constraints we should know?
- Anything we haven't asked that we should have?Adapt the blocks to your service - the structure matters more than the exact wording.
How to make it easy to complete
The best questionnaire is the one that gets finished. A few rules: keep it as short as it can be while still complete, gather brand assets and access in the same place (a secure form or password manager, never plain-text email), and make the discovery-call notes feed it so you're not re-asking things the client already told you. Pre-fill anything you already know.
Crucially, pin down scope of work expectations here too - a question or two about what's in and out of scope at intake saves a painful conversation later.
Turn the intake into momentum
Once answers are in, use them fast: confirm you've received everything, turn the answers into a brief, and reference them in the kickoff so the client sees their words shaping the work. Nothing builds early trust like a client realising you actually read what they wrote.
The questionnaire is one step in a full onboarding sequence. For the whole flow and a ready-made checklist, see the client onboarding guide and the onboarding checklist.
Frequently asked questions
What should a client onboarding questionnaire include?
Five blocks: the business (what they do, customers, competitors, differentiators), goals and success metrics, brand and assets (guidelines, tone, access to files), logistics (main contact, approver, tool access, communication), and context (what they've tried, constraints, anything you missed).
Why use a client onboarding questionnaire?
To gather everything you need in one structured ask instead of a fortnight of scattered emails - so work starts faster, the client feels you're organised, and onboarding becomes a repeatable process anyone on the team can run.
How long should an onboarding questionnaire be?
As short as it can be while still complete. Group questions into clear blocks so the client can finish in one sitting, pre-fill anything you already know, and avoid re-asking what came up on the discovery call.
When should you send the onboarding questionnaire?
Right after signing, as part of the welcome - early enough that answers are in before the kickoff, so the kickoff can focus on alignment rather than basic fact-gathering.
