Client onboarding: a free checklist with deadlines and owners.

What is client onboarding

Client onboarding is the path between "contract signed" and "client in the routine." In it you confirm billing details, receive access, align on what was sold, introduce the team and make the first delivery. It's the phase in which the client decides, without saying so, whether they made a good choice.

The most common problem is the gap. Sales closes, the production team doesn't know yet, finance hasn't received the CNPJ (Brazil's company tax ID), and the client waits a week for an email that nobody knew was theirs to send. A checklist with an owner and a due date on every line closes that gap.

How to fill in the onboarding checklist

Step by step to build your process

1. List what already happens today. Think about your last three clients: what had to be done and what was forgotten?
2. Order by what blocks everything else. Usually, billing details and access come before the kickoff, because without them nobody can start.
3. Give each line an owner and a due date. A due date in days after signing works for any new client.
4. Mark what depends on the client. Access and approvals are often delayed on the client's side. Keep that visible, so nobody takes the blame alone.
5. Review every 5 or 10 clients. A checklist that never changes is a sign that nobody is learning from it.

Common onboarding mistakes

• Waiting for the client to ask. A new client doesn't know what to ask. Whoever is leading has to send the next steps without being prompted.
• Asking for access a little at a time. Send the complete list at once, so the client can handle it in a single task.
• Skipping the kickoff. A 45-minute meeting with both teams aligns expectations and avoids the question "but wasn't that included?"
• Forgetting the 30-day review. That's where the client tells you what's bothering them before it turns into a cancellation.

What to measure to know if onboarding works

Without measuring, the process becomes a ritual. Three simple numbers already show whether it's working: how many days pass between signing and the first delivery, how many checklist tasks were late on each side's account (your team or the client), and what the client said at the 30-day meeting. Write down all three for every new client, in the same spreadsheet as the checklist, and compare after a few months.

If the first delivery almost always takes longer than agreed, the problem is usually at the start: access that arrives late, an incomplete briefing or an approver who wasn't at the kickoff. The checklist shows where.

When the checklist isn't enough

The checklist organizes the client's entry, but it doesn't run the project itself. For that, combine it with a project brief, which records what the client wants, and a weekly status report, which keeps the client informed after the first delivery. If the service has many chained steps, a schedule is also worth having.

How to use onboarding in Tasskee

1. Create an "Onboarding" project and add the template's tasks, with an assignee and a due date. The Kanban board shows what stage each task is in.
2. Group by stage using workstreams (welcome, finance, access, kickoff), to see the progress of each block.
3. When a new client arrives, create a project with the same tasks and adjust only what's specific.
4. Use a reminder automation before the due date and another for stalled tasks, so the process follows up on itself.
5. Invite the client to the guest portal. They follow the project, comment and approve, and don't take up a seat on the plan.
