If you're reading this, you've already won the battle - your proposal got accepted, signed, and paid. You have a new client now. Congrats! But hold on, the journey isn't complete yet - you need to onboard them properly before diving into the actual work.
Many agencies and business owners skip onboarding or rush through it. Big mistake. A solid onboarding process can be what separates a happy client from a disappointed one. Let's talk about what client onboarding really is and how you can nail it.
What is client onboarding?

Client onboarding is basically how you welcome a new client into your business. This is when you show them what you do, explain your process, and lay down clear expectations for your working relationship. Get this foundation right, and you'll see better communication and happier clients down the line.
Why is client onboarding important?
You might think skipping onboarding saves time, especially when you're juggling multiple clients. But here's the reality - more than 90% of customers feel that businesses could do way better with their onboarding. Here's why it matters.
Lower churn rate - when clients understand your brand and process, they stick around longer. Plus, the personal attention you give them during onboarding makes them feel valued, not just like another number.
Clear expectations - imagine your client is expecting a complete website overhaul, but you're only doing technical SEO fixes. That's a recipe for disaster. Your proposal should set expectations first, but onboarding is your second chance to clarify exactly what you'll deliver and how you'll do it.
Getting the details right - onboarding gives you a perfect opportunity to collect any missing information you need before jumping into their project.
Client onboarding best practices
Now that you see why onboarding matters, let's walk through the key steps to make your onboarding process smooth and effective.
1. Start with the proposal
Your client should already know the basics before onboarding begins. Think of onboarding as a refresher, not the first time they're hearing about your services. They should learn what you do and how you'll solve their problem from your proposal itself.
Here's an important rule - only start onboarding after both parties have signed the proposal and ideally, after you've received payment. This ensures everyone's committed and ready to move forward.
Your proposal should explain the client's situation, your solution, timeline, pricing, and all the important details. Strong proposals also include terms and conditions to protect everyone involved.

2. Send a questionnaire
Anyone who's worked with clients knows this truth - they rarely give you everything you need upfront. This is especially true for clients who've never hired an agency or freelancer before.
You'll definitely have questions before starting work. But you don't want your onboarding meeting turning into a 3-hour interrogation session. The smart move? Send an onboarding questionnaire ahead of time with your most important questions.
Your questionnaire should cover the common questions you ask before starting any project. What you ask will depend on your service and the specific project.
You could just send an email and wait for responses, but there are better ways. Try using Google Forms, Typeform, or Airtable instead. These tools let you collect responses instantly, and they're easier for clients to fill out. Even better - connect them to your CRM or project management tool so the information flows automatically where you need it.
3. Have a kickoff call
Nothing beats talking to a real person. Even if your work doesn't need constant client calls, you should schedule at least one meeting during onboarding. Once your client signs and pays, set up the kickoff call.
Video calls have become the standard now, which actually makes things simpler. Send a meeting invite, and you're good to go.
The goal of this call is to walk your client through what's coming. Ask any quick questions you still have, discuss deliverables and timelines, and let them ask anything that's on their mind.
This is also when you introduce whoever from your team will be working on their account. Putting faces to names builds trust and makes the whole relationship feel more personal.
4. Follow up
Here's one of the worst mistakes you can make - leaving your client in the dark about their project. If you go silent for too long, they'll start thinking you're not actually doing anything. Some might even forget they hired you at all.
Don't let this happen. Set up regular follow-up emails and calls. How often depends on your project length. For multi-month projects, a monthly check-in works great. For one-month projects, try weekly updates or progress reports.
Regular follow-ups show your client that you're working on their project even when they're not watching over your shoulder. They're also perfect for sharing progress and making sure the client is happy with your work.
Conclusion
Your onboarding process shapes how clients see your brand and your work. Even if you deliver amazing results, poor onboarding can ruin the entire experience. You've done great work getting the client - now show them your professionalism right from the start with an onboarding process that sets the tone for everything that follows.
