The 7-step agency onboarding checklist that actually scales

Why onboarding is retention

Clients decide whether they trust you in the first ten days — long before your first campaign results land. A smooth, predictable onboarding is the highest-leverage thing an agency can systematize.

The 7 steps

1. Kickoff brief. Capture the business goal in one sentence, the breakeven ROAS, and the one metric that defines success.
2. Access. Connect the ad accounts — Meta, Google, TikTok — and validate data is flowing before moving on.
3. Baseline. Snapshot current ROAS, spend, and revenue per account so you have a 'before' to measure against.
4. Naming & structure. Agree a campaign naming convention so reports stay readable as the account grows.
5. Alert routes. Decide who gets notified when an account drifts below breakeven — Slack, email, or both.
6. Reporting cadence. Set the white-label report schedule before the client asks for it.
7. First win. Ship the first report at the promised time, even if early, with one concrete recommendation.

The part nobody tells you

Steps 1 and 2 are where most onborading stalls — waiting on access, chasing a brief. Automate the ask: a guided intake that captures the brief and the platform permissions in one flow, so by the time you open the file the data is already syncing.

A signed client sitting in onboarding limbo is a client halfway to churning.

Run this checklist for every new client and the messy, bespoke first week turns into a repeatable system.
