Build a Client Onboarding Checklist That Survives Missing Information

The welcome email was sent. The kickoff is on the calendar. But nobody has the approved scope or the files needed to start. Onboarding is complete when the required conditions are met—not when the welcome sequence has finished sending.

Define ready to start For a fictional design-service client, the conditions might be: agreement approved, scope confirmed, project contact named, required materials reviewed, and kickoff confirmed. Adapt the list to your service. Bring accepted details forward from the quote brief instead of asking the customer to repeat them. Use the FTC’s privacy guidance to avoid collecting unnecessary personal information.

Track evidence, not just checkmarks For each requirement, record owner, status, evidence link, and next action. Use Requested, Received, Reviewed, and Waived where appropriate. Received is not Reviewed. A file named “brand assets” may be empty or outdated. The file-handling guide helps keep the source clear; Drive sharing instructions help you check access. For a waived requirement, record who approved the exception and why. Follow the approval process rather than silently marking the item complete.

Show what blocks what If an approved scope is required before kickoff, the calendar event must not override that dependency. Follow the booking guide to distinguish proposed and confirmed times. Google’s appointment-schedule instructions cover the scheduling setup, not your business’s readiness rules. Useful update: “Waiting for usable logo files. Daniel owns follow-up. Kickoff readiness is blocked until the files are reviewed or an alternative is approved.” Unhelpful update: “Onboarding 90% done.” The missing 10% may be the only thing that matters today.

Make reminders conditional Stop requests when an item is received, replaced, or legitimately waived. Recheck the current record before contact using the reminder stop rules. Assign missing or wrong materials through the handoff process. Do not trap a client in a loop asking for something they cannot supply.

Test four awkward cases Try a wrong attachment, inaccessible link, changed contact, and unavailable required item. Use the test format to record who gets the exception and what happens next. Your deliverable is a checklist where every completed requirement has evidence. That is more useful to the delivery team than a polished welcome sequence that conceals unfinished work.
