Agency Client Onboarding

The champagne has been popped. The contract is signed. Your sales team is celebrating a new win. But for your Account Managers, the panic is just setting in.

The period immediately following a closed deal—the onboarding phase—is the most fragile part of the client lifecycle. It is where buyer’s remorse sets in. If your new client feels chaos, they will assume your work is chaotic, too.

A static PDF checklist or a messy Google Doc isn't enough to manage this complexity. You need an executable workflow.

Why "Winging It" Costs You Clients

Client onboarding is not just about administrative tasks; it is your first opportunity to demonstrate competence.

When you send five different emails asking for five different login passwords, you look disorganized. When you ask a client a question they already answered during the sales process, you look inattentive.

A standardized onboarding process solves three critical problems:

  • It kills "Scope Creep" early: By clearly defining deliverables in the kickoff.
  • It reduces "Time-to-Value": The faster you get access to assets, the faster you can launch campaigns.
  • It eliminates the "Bus Factor": If your lead Account Manager gets sick, anyone else can pick up the checklist and see exactly where the client stands.

The 4 Phases of a Perfect Agency Onboarding

We have built a pre-made template for this inside CheckFlow, but let’s look at the philosophy behind the steps.

Phase 1: The Internal Handoff (Sales to Service)

Before you ever email the client, your internal house must be in order. The worst thing you can do is make the client repeat themselves to the new Account Manager.

The Checklist Steps:

  • Review the Contract: Confirm the SOW (Statement of Work) matches the sales promise.
  • The "Brain Dump": Sales briefs the Account Manager on client personality, pain points, and "red flags."
  • Assign the Team: Who is the lead designer? Who is the copywriter? Assign these roles in your project management tool immediately.
  • Create the Client Folder: Whether it’s Google Drive or Dropbox, set up the file structure now so assets don't get lost later.

Phase 2: The "Tech & Access" Audit

This is the bottleneck. You cannot run ads or fix SEO without access. Do not trickle these requests out over two weeks. Send one comprehensive request.

The Checklist Steps:

  • Asset Request Form: Send a secure form to collect Brand Guidelines, Logos (Vector format), and Typography.
  • Access Request: Request "Admin" or "Partner" access to:
    • Google Analytics (GA4)
    • Google Tag Manager
    • Meta Business Suite
    • CMS (WordPress/Shopify) access
  • Audit Existing Accounts: Before you change anything, document the current state of their accounts for your baseline report.

Phase 3: The Kickoff Call

This is the "Wedding Day" of the business relationship. It needs to be scripted and rehearsed. Never go into a kickoff call without an agenda—it invites the client to take control and derail the meeting.

The Checklist Steps:

  • Send Agenda 48 Hours Prior: Let them know exactly what will be discussed.
  • Define Success Metrics (KPIs): Get them to say out loud what "success" looks like to them. Is it ROAS? Is it Lead Volume? Is it Brand Awareness?
  • Communication Protocols: Establish how you will talk. (e.g., "We use Slack for daily comms, but approvals must go through email.")
  • The "Next Steps" Timeline: End the call by telling them exactly what happens in the next 7 days.

Phase 4: The Strategy Setup

Now that you have the keys and the relationship is established, the work begins.

The Checklist Steps:

  • Competitor Analysis: Complete the initial research into their top 3 competitors.
  • Strategy Document Creation: Draft the 90-day roadmap.
  • Internal Review: Have the Creative Director or Head of Strategy sign off on the roadmap before sending it to the client.

How to Automate This in CheckFlow

You could print this list out, or put it in a spreadsheet. But spreadsheets don't send reminders, and paper gets lost.

By using the Marketing Agency Client Onboarding Template in CheckFlow, you can run a fresh instance of this process for every new client.

  • Assign Tasks: Assign specific steps to your SEO specialist and others to your Designer.
  • Set Due Dates: Ensure the "Kickoff Call" happens within 5 days of contract signing.
  • Track Progress: See at a glance which clients are stuck in the "Access Request" phase and need a nudge.

Stop reinventing the wheel.

Standardization is the secret to scaling an agency. When you stop worrying about how to onboard, you can focus on how to get results.
