The Client Onboarding Checklist Every Agency Needs

The first two weeks set the tone for the entire client relationship. A messy onboarding — missing assets, unclear scope, "who's my point of contact?" — creates friction that follows the project to the end. A repeatable onboarding checklist fixes that. Here's one you can adapt.

Before kickoff: lock the basics

Get the agreement signed — scope, timeline, and payment terms in writing, e-signed.
Send and collect the first invoice or deposit before work begins.
Share a simple intake form to gather brand assets, logins, and requirements.
Confirm the single point of contact on each side.

Set up the client's space

Give the client one branded place to live in for the project — not five tools. Set up their portal with the deliverables area, the roadmap, the signed agreement, and their invoices all in one view. This is where "where is that file?" emails go to die.

The kickoff call

Walk through the roadmap and confirm milestones and dates.
Set expectations for communication: where updates happen and how fast you reply.
Show them the portal so they know exactly where to find things.
Agree on how feedback and approvals will work.

First week: build momentum

Deliver something small and visible in the first few days — an early draft, a moodboard, a quick win. Momentum early builds trust that carries through the harder middle of the project.

Make it repeatable

The point of a checklist is to run it the same way every time. Turn the steps above into a template client space you can duplicate, so onboarding the tenth client is as smooth as the first — and nothing falls through the cracks.

BloomDash lets you set up a reusable client space with agreements, intake, roadmap, and invoicing built in — so every onboarding follows the same polished path.

Give every client a branded portal for their assets, invoices, and updates — under your own domain.
