TLDR: Every delayed agency project starts with missing brand assets, ad account access, or creative approvals. This free 10-item checklist gives you a repeatable intake process so your team has everything they need before the kickoff call — not three weeks after it.

You just signed a new client. The contract is in, the kickoff call is scheduled, and your team is ready to start. There’s just one problem: you still don’t have the logo files, nobody’s shared ad account access, and the brand guidelines are “somewhere in their Drive.”

This is the agency onboarding problem. It happens with nearly every new client, and it delays project timelines by days — sometimes weeks. The creative team can’t start without brand assets. The media buyer can’t launch campaigns without ad account access. The strategist can’t finalize the plan without competitor research and audience data.

Why Agencies Need a Standardized Onboarding Checklist

When you’re managing multiple client relationships simultaneously, relying on memory or ad-hoc email threads to collect onboarding materials is a recipe for dropped balls. A standardized checklist ensures that every client goes through the same process, and nothing gets missed regardless of which account manager is running the onboarding.

Beyond efficiency, a structured onboarding process signals professionalism. Clients notice when your intake process is smooth and organized. It sets expectations for how the entire engagement will run. First impressions matter, and onboarding is your first impression after the sale.

The checklist also protects your margins. Every hour spent chasing brand assets is an hour not spent on billable work. Every week of delay waiting for ad account access is a week of lost campaign performance. A tight onboarding process means faster time-to-value for your clients and better utilization for your team.

What’s in This Checklist

The checklist below covers the 10 essential items agencies need from every new client before project work begins. It spans brand assets, credentials, strategic inputs, and approvals — the items that most commonly hold up agency projects.
