Agency Onboarding Checklist: First 30 Days With a New Client

Why Onboarding Makes or Breaks Client Relationships

You close a deal. The client signs. You celebrate.

Then... crickets. No one knows what happens next.

Three weeks later:

  • Client is confused about next steps
  • You haven't gathered the info you need
  • First deliverable is delayed
  • Client is already frustrated

Bad onboarding = Churn within 90 days.

Good onboarding:

  • Sets clear expectations
  • Gets you the info you need
  • Builds trust early
  • Creates momentum

This is your complete 30-day onboarding checklist.

Day 1: The Welcome (Contract Signed)

Why it works: Immediate clarity. No awkward silence.

Action 2: Send Portal Access + Onboarding Form

Portal should include:

  • Project dashboard
  • Contact information
  • Meeting calendar
  • File sharing area

Onboarding form should ask:

  • Brand assets (logo, colors, fonts)
  • Access credentials (website, social accounts, analytics)
  • Brand guidelines (if they exist)
  • Examples of work they love
  • Examples of what to avoid
  • Key stakeholders and decision-makers
  • Success metrics

Action 3: Internal Team Kickoff

Before the client kickoff, have an internal meeting:

Discuss:

  • What did sales promise?
  • What are the client's goals?
  • Who's on the team?
  • What's the timeline?
  • What could go wrong?

Assign roles:

  • Account lead
  • Project manager
  • Key specialists

Create:

  • Project brief
  • Initial timeline
  • Risk assessment

Days 2-7: Information Gathering

Action 4: Schedule Kickoff Meeting (Within 48 Hours)

Send calendar invite for 60-90 minutes within the next 7 days.

Agenda:

  1. Team introductions (10 min)
  2. Your understanding of their goals (10 min)
  3. Walk through proposed plan + timeline (20 min)
  4. Gather missing information (15 min)
  5. Set communication expectations (10 min)
  6. Q&A (10 min)

Access needed:

  • CRM system
  • Any other tools you'll need

Assets needed:

  • Logo files (vector + PNG)
  • Brand colors (hex codes)
  • Fonts
  • Product images
  • Previous campaign materials

Pro tip: Create a shared folder (Google Drive or Dropbox) for all assets. Keep everything organized from day one.

Action 6: Research Their Business

Before the kickoff, do your homework:

  1. Review their website (15 min)
    • What's their value prop?
    • Who's their target audience?
    • What do they sell?
  2. Check their social media (10 min)
    • What's working?
    • What's not?
    • What's their voice/tone?
  3. Google their competitors (15 min)
    • Who are they up against?
    • What are competitors doing well?
  4. Read reviews (10 min)
    • What do customers love?
    • What do they complain about?

Total time: 50 minutes. But you'll show up WAY more prepared than 95% of agencies.

"We started doing competitor research before kickoff meetings. Clients are SHOCKED that we come prepared. It's a huge trust builder."

— Sarah Kim · Founder, Bloom Agency

Days 7-14: The Kickoff

Action 7: Run the Kickoff Meeting

Opening (5 min): "Thanks for joining. Today's goal is to align on the plan, confirm timeline, and make sure we have everything we need to start strong. We'll be done in 60 minutes."

Team intros (10 min):

  • Each person introduces themselves
  • What they do
  • Fun fact (keeps it human)

Your understanding of their goals (10 min): "Before we show you the plan, let me confirm what we heard in our sales conversations:

  • Your goal is [X]
  • You're trying to achieve [Y]
  • Success looks like [Z]

Did we get that right? Anything to add?"

Walk through plan + timeline (20 min):

  • High-level strategy
  • Phase-by-phase breakdown
  • Key milestones
  • Deliverable dates

Gather missing info (15 min): "Here's what we still need from you:

  • Brand guidelines (by Friday)
  • Analytics access (by Monday)
  • Competitor list (by Wednesday)

Can you commit to these dates?"

Set communication expectations (10 min):

  • How often will we meet? (Weekly? Biweekly?)
  • What's the best way to reach you? (Email? Slack?)
  • Response time expectations (24 hours on weekdays?)
  • Approval turnaround (2-3 business days?)

Q&A (10 min)

Closing: "Great. I'll send a recap email with all of this documented. Next steps: you'll send us [X] by [date], we'll deliver [Y] by [date]. Our next meeting is [date]. Excited to get started!"

Days 14-21: Strategy & First Deliverables

Action 9: Deliver Strategy Document

What to include:

  • Situation analysis (where they are now)
  • Goals & success metrics
  • Target audience insights
  • Competitive landscape
  • Recommended strategy
  • Tactical plan (what you'll do)
  • Timeline & milestones
  • Budget allocation (if applicable)

Format: PDF or slide deck (whatever looks professional)

How to present: Schedule 30-minute call to walk through it. Don't just email and hope they read it.

Action 10: Set Up Project Tracking

Create project in your system:

  • All tasks
  • Owners
  • Due dates
  • Dependencies

Give client visibility:

  • Portal access to see progress
  • Automated status updates
  • Clear view of what's pending their approval

Action 11: Start Weekly Status Updates

Every Monday (or your chosen day), send:

Subject: Weekly Update - [Project Name] - Week of [Date]

Hi [Client],

Quick update on what happened last week and what's coming:

COMPLETED:
âś“ Strategy deck finalized
âś“ First round of creative concepting

IN PROGRESS:
→ Ad copy drafts (ready for review Wednesday)
→ Landing page wireframes (ready Thursday)

UPCOMING:
→ Creative review meeting (Friday 10 AM)
→ Final approvals needed by next Tuesday

BLOCKERS:
⚠️ Still waiting on logo files (needed by Wednesday to stay on schedule)

Next meeting: Friday 2/17 at 10 AM

- [Your Name]

Why it works: Client always knows status. No surprises.

Days 21-30: Building Momentum

Action 12: Deliver First Tangible Work

This is critical. By day 21-30, client should see something:

  • Strategy document
  • First creative concepts
  • Initial campaign setup
  • Website mockups

Something they can react to.

Why it matters: Until they see work, they're wondering if you're worth the money. Show value early.

Action 13: Get First Approval

Walk client through approval process:

"Here's how approvals work:

  1. We'll submit work in the portal
  2. You'll get an email notification
  3. Click to review and approve (or request changes)
  4. We need feedback within 2 business days to stay on schedule

Let's test it now with this first deliverable. Can you approve or give feedback by end of day Thursday?"

Training them on your process = fewer delays later.

Action 14: Schedule 30-Day Check-In

At the end of the first month, schedule a 30-minute call:

Agenda:

  • How's it going so far?
  • Are we meeting expectations?
  • Anything we should do differently?
  • Confirm goals for next 30 days

Why it works: Catches issues early. Shows you care about their experience.

Common Onboarding Mistakes

Mistake #1: No Clear Next Steps After Contract

The trap: Contract is signed. Then... nothing for a week.

The fix: Welcome email within 1 hour. Kickoff scheduled within 7 days.

Mistake #2: Asking for Information Multiple Times

The trap: "Oh, we also need your logo." Week later: "Can you send those brand colors again?"

The fix: One comprehensive onboarding form. Get everything upfront.

Mistake #3: Overpromising in Sales, Underdelivering in Onboarding

The trap: Sales says "We'll launch in 2 weeks!" Reality: It takes 6 weeks.

The fix: Realistic timelines from day one. Underpromise, overdeliver.

Mistake #4: No Dedicated Point of Contact

The trap: Client emails multiple people. No one responds. Everyone thinks someone else will.

The fix: One account lead. All communication goes through them.

The Bottom Line

Great onboarding:
