Client Onboarding Checklist: How Agencies & Freelancers Onboard Clients Without the Chaos

Client Onboarding Software That Keeps Agencies Organized

Let's be honest—onboarding new clients shouldn't feel like herding cats. Between sending welcome emails, chasing down brand assets, collecting login credentials, and getting contract signatures, things slip through the cracks. Your team is switching between Slack, email, Google Drive, and project management tools just to get one client started.

TaskTag replaces that fragmented mess with a chat-based client onboarding workflow. Every contract, brand doc, approval, and login guide lives in one searchable project—not scattered across platforms.

Who this is for: Marketing agencies, design studios, freelance consultants, SaaS customer success teams, and any service business that needs a repeatable client onboarding process.

Common Client Onboarding Challenges: Lost Files, Forgotten Steps, and Frustrated Teams

Without a structured client onboarding system, most teams rely on:

• Email threads that become impossible to search
• Shared drives where files are buried in folders
• Manual checklists in spreadsheets or Notion
• Slack channels that mix internal chat with client communication
• No clear record of what was approved or when

This creates:

• Missed onboarding steps that delay project kickoff
• Clients asking "Did you get my files?" repeatedly
• Team members working from outdated information
• No accountability for who's responsible for what
• Unprofessional client experience from day one

With TaskTag's client onboarding checklist workflow:

• You create a dedicated project for each new client
• Your team uses a group chat to coordinate onboarding tasks in real time
• Each client gets an onboarding task with a custom checklist you can reuse
• All contracts, brand docs, and credentials are uploaded where the conversation happens
• You track progress with hashtags—no manual status updates needed
• Clients can upload files directly using simple task assignments
• When onboarding is complete, you archive the record or duplicate the template for your next client

Step 1: Create a Client Project for Organized Onboarding

• Acme Corp - Q1 2026 Social Media Campaign
• Smith Consulting - Website Redesign
• TechStart SaaS - Customer Success Onboarding
• Riverdale Construction - Branding & Marketing

Pro Tip: Use consistent naming conventions so your team can quickly find any client project. For agencies managing multiple clients, check out our guide on TaskTag vs Trello for growing teams.

Step 2: Set Up a Client Communication Hub with Group Chat

• Add account managers, designers, developers, or strategists
• Include client stakeholders who need visibility
• Use this chat for quick questions, status updates, or timeline changes

Why this matters: Instead of scattered Slack DMs and email threads, everything client-related lives in one searchable feed. Learn more about centralizing client communication with TaskTag.

Step 3: Build Your Client Onboarding Checklist Task Template

Create a task called "Client Onboarding - [Client Name]" and build your checklist:

Agency Client Onboarding Checklist Template:

• [ ] Welcome email sent to primary contact
• [ ] Service agreement signed and uploaded
• [ ] Brand guidelines document received
• [ ] Logo files (PNG, SVG, EPS) collected
• [ ] Website login credentials shared securely
• [ ] Social media account access confirmed
• [ ] Project timeline and milestones reviewed
• [ ] Kickoff meeting scheduled
• [ ] Internal team briefed on client goals
• [ ] Client added to project communication hub

SaaS Customer Onboarding Checklist Template:

• [ ] Welcome email and getting started guide sent
• [ ] Account provisioned and credentials shared
• [ ] Onboarding call scheduled with CSM
• [ ] Integration requirements documented
• [ ] Team training session completed
• [ ] Success metrics and goals defined
• [ ] Support contact information provided
• [ ] First check-in meeting scheduled (30 days)

Freelance Consultant Onboarding Checklist:

• [ ] Project scope document signed
• [ ] Invoice and payment terms agreed upon
• [ ] Discovery questionnaire completed by client
• [ ] Access to necessary tools/platforms granted
• [ ] Communication preferences established
• [ ] Project kickoff date confirmed
• [ ] First deliverable deadline set

Why reusable templates save time: Build it once, duplicate it for every new client. No more rebuilding onboarding checklists from scratch.

Step 4: Centralize All Client Onboarding Communication in Chat

As your team works through onboarding, they post updates in the project chat using hashtags:

Example onboarding updates:

"Contract signed by Sarah at Acme Corp. Moving forward with kickoff next Tuesday. #Onboarding_AcmeCorp"

"Still waiting on brand guidelines. Sent follow-up email with deadline reminder. #Onboarding_AcmeCorp"

"Received all logo files. Organized in the Brand Assets task. Ready for design phase. #Onboarding_AcmeCorp"

"Kickoff call completed. Client approved timeline and first milestone deliverables. #Onboarding_AcmeCorp"

All chat messages with hashtags are automatically linked to your onboarding task—creating a searchable, timestamped record of every onboarding activity.

Step 5: Upload Contracts, Brand Docs, and Login Guides Where Discussion Happens

• Signed contracts and service agreements
• Brand guidelines and style guides
• Logo files (all formats)
• Website and platform login credentials (use task comments for secure sharing)
• Project briefs and discovery documents
• Onboarding presentations or welcome decks

Files can be uploaded:

• Directly in the onboarding task
• In chat messages using the project hashtag
• By the client themselves through assigned tasks

Pro Tip: Create a task called "Brand Assets - [Client Name]" and assign it to your client contact. They upload everything you need in one place. Read our guide on building a client upload portal.

All files are timestamped and permanently attached to the project—no more "Can you resend that?" emails.

Step 6: Track Client Onboarding Progress with Hashtag Search

• All messages related to client onboarding
• Every file uploaded during onboarding
• Task approvals and sign-offs
• Outstanding items that need attention

Search examples:

• #Onboarding_AcmeCorp - Shows complete onboarding activity
• #BrandAssets - Shows all brand files across clients
• #ContractSigned - Shows which clients have signed agreements

This makes it easy to:

• Answer "What's the status?" questions immediately
• Identify bottlenecks holding up onboarding
• Review past client onboardings when refining your process
• Train new team members using real examples

Step 7: Complete Client Onboarding and Archive or Duplicate for Next Client

• ✅ All checklist items are checked off
• 📎 Contracts, brand docs, and credentials are uploaded
• 💬 Kickoff meeting notes are documented in chat
• 🏷️ Everything is tagged with the client hashtag

Mark the onboarding task Complete and move into project execution.

What happens next:

For your current client:

• The onboarding record is permanently archived with timestamps
• Your team can reference onboarding details anytime during the project
• If questions arise, search the hashtag to find the answer instantly

For your next client:

• Duplicate the onboarding task and rename it for the new client
• Your checklist template carries over automatically
• Adjust any client-specific details and you're ready to go
