Client Onboarding Checklist for Small Agencies

A good onboarding process answers four questions: what are we delivering, who makes decisions, what do we need from the client, and when can work begin? Use the checklist below as a starting point. Adapt the order and deadlines to your agreement and the size of the project.

Before the kickoff

• Confirm the signed scope, deliverables, exclusions and commercial terms with the people responsible for the project.
• Name the agency lead, client contact and decision-maker. Agree on a backup for each important decision.
• Agree on the communication channel, meeting cadence and expected response times.
• List the information, assets and access needed before work begins. Request access through the client's approved access-management process; do not collect passwords in a regular form or spreadsheet.
• Define the goals and measures that both sides can realistically review. Record the source and reporting period for each measure.

From agreement to first deliverable

1. Welcome the client

Send a short welcome message identifying the project lead and the next action. Include a link to the agreed scope and a proposed kickoff agenda.

2. Collect the brief and assets

Ask for the audience, offer, existing materials, brand guidance and any constraints relevant to the work. Give each request a named owner and a target date. Mark sensitive material for an approved transfer method.

3. Arrange access

List required platforms and the minimum access needed. The client or an authorized administrator should grant access directly. Confirm access works, record who owns it, and plan to remove it when it is no longer needed.

4. Run the kickoff

Review the objective, scope, roles, timeline and dependencies. Capture unresolved questions and send the decision log to the client. Do not treat an unanswered question as approval.

5. Agree the first deliverable

Define what the first output contains, who reviews it and what constitutes approval. Allow time for feedback and explain where comments should be collected.

6. Review and hand off

Before delivery, check the work against the agreed scope, verify links and claims, and confirm the reviewer has access. Record the decision and next action after feedback arrives.

Give every task an owner

Use one row per task with these fields: task, owner, target date, status, dependency and evidence of completion. A completed task should have a clear outcome—for example, “the client granted the agreed role and the agency lead confirmed access.”

Illustrative example: A three-person agency is preparing a new client's reporting project. The agency lead owns the kickoff agenda; the client contact owns inviting the agency to the analytics account; and the reviewer approves the first reporting outline. This example is fictional and is not a reported client engagement.

When the client is late

Flag the missing item, its owner and the work it blocks. Send a concise reminder using the agreed channel. If the delay affects the schedule, tell the client which milestone may move and agree a revised date. Record the decision instead of silently changing the plan.

What to automate

Creating folders, setting up internal tasks and preparing reminders can be candidates for automation after the manual process works. Keep scope acceptance, access decisions and sensitive client communication under human review. Test duplicates, missing fields and permission failures before relying on an automation.

When a spreadsheet is enough

A shared checklist may be sufficient when a small team has a manageable number of active projects and a clear owner for each task. Consider a dedicated portal or collection tool if handoffs, permissions or follow-ups become difficult to manage. Compare the actual problem and total cost before adding another subscription.

Review the process

After each onboarding, record the time from agreement to kickoff, missing information at kickoff and the number of manual follow-ups. Review the pattern with the team and change one bottleneck at a time. These are suggested measures; no time saving is assumed.
