A client onboarding checklist lists every step between a signed contract and the moment a new client sees results, with an owner and a deadline for each. The first 30 days set the tone for the whole relationship, and most onboarding problems come from missed handoffs: sales promised something the delivery team never heard about, or a document sat in someone's inbox for a week. A checklist makes those handoffs visible.
The client onboarding checklist
Phase 1: Before kickoff (days 0–3)
- ☐ Contract signed and countersigned; copy stored with the client record.
- ☐ Sales-to-delivery handoff: goals, promises, stakeholders, risks.
- ☐ Client created in CRM, billing and project tools.
- ☐ Account manager and team assigned.
- ☐ Welcome email sent with next steps and key contacts.
- ☐ Portal access created for client contacts.
- ☐ First invoice or deposit issued.
Phase 2: Information and document collection (days 1–7)
- ☐ Onboarding questionnaire sent: goals, KPIs, brand, systems, contacts.
- ☐ Required documents requested: tax forms, access credentials via a secure method, assets, data exports.
- ☐ Access to client systems granted and tested.
- ☐ Missing items chased automatically after 3 days.
Phase 3: Kickoff (days 5–10)
- ☐ Kickoff meeting scheduled with all stakeholders.
- ☐ Agenda shared in advance: goals, scope, timeline, roles, communication.
- ☐ Success metrics agreed and written down.
- ☐ Communication plan agreed: channels, meeting cadence, escalation path.
- ☐ Kickoff notes shared within 24 hours.
Phase 4: Setup and first delivery (days 10–30)
- ☐ Project plan published with milestones.
- ☐ Internal setup completed: workspaces, integrations, reporting.
- ☐ First deliverable shipped (a quick win).
- ☐ Client approval collected on first deliverable.
Phase 5: Review (day 30)
- ☐ 30-day check-in: progress against goals, feedback, open issues.
- ☐ Onboarding satisfaction survey sent.
- ☐ Handoff to ongoing account management confirmed.
- ☐ Lessons learned added to the onboarding template.

Tips for a better onboarding
- Ask for everything once. One questionnaire and one document list, not ten emails.
- Show progress. Clients relax when they can see which steps are done.
- Deliver a quick win early. Something tangible in the first two weeks builds trust.
- Never collect credentials by email. Use a secure portal or password manager sharing.
- Automate reminders. Chasing is the most time-consuming part of onboarding.
