Agency Client Onboarding Checklist
A smooth onboarding experience sets the tone for the entire client relationship. When clients feel organized, informed, and confident from day one, they're more likely to stay long-term and refer others to you. A chaotic start — missed details, unclear expectations, delayed deliverables — leads to early churn and bad reviews.
This checklist is designed for agencies onboarding new marketing, SaaS, or services clients. It covers everything from the first welcome email to the first deliverable, with clear ownership and timelines for each step.
Print this out, add it to your project management tool, or turn it into a Standard Operating Procedure (SOP) that your team follows for every new client.
Templates
Pre-Kickoff (Before First Meeting)
Complete these items before the kickoff call. Preparation is what separates professional agencies from freelancers winging it.
☐ Send welcome email with onboarding timeline and what to expect ☐ Send client intake form (business info, logins, brand assets, goals) ☐ Set up client in CRM / project management tool ☐ Create shared folder (Google Drive or Dropbox) for assets and deliverables ☐ Create dedicated Slack channel or communication thread ☐ Review signed contract/SOW for scope, deliverables, and deadlines ☐ Assign internal team members and notify them of the new account ☐ Schedule kickoff call (send calendar invite with agenda)
Kickoff Call Agenda
Use this as your agenda for the first client meeting. Cover goals, process, and communication expectations.
☐ Introductions — who's who on both sides ☐ Review goals and success metrics (what does 'winning' look like in 90 days?) ☐ Walk through the scope of work and timeline ☐ Discuss communication preferences (email, Slack, calls? How often?) ☐ Review reporting schedule and what reports will include ☐ Collect any remaining access/logins needed ☐ Set expectations for first deliverable and next steps ☐ Confirm next check-in date ☐ Ask: "Is there anything we haven't covered that's important to you?"
Post-Kickoff Setup (Week 1)
The first week after kickoff is critical. Get all systems set up and deliver a quick win.
☐ Collect all logins and access (Google Analytics, ad accounts, CMS, CRM, etc.) ☐ Complete technical audit / baseline assessment ☐ Set up tracking and reporting dashboards ☐ Configure any tools or platforms (white-label setup, automation, etc.) ☐ Send client a recap email summarizing kickoff decisions and next steps ☐ Deliver first 'quick win' within 5-7 days (builds confidence) ☐ Schedule first progress check-in for end of week 1 or early week 2 ☐ Add client to monthly reporting calendar
Ongoing Maintenance (Monthly)
Recurring items to maintain a healthy client relationship. Do these every month.
☐ Send monthly performance report (before the client meeting) ☐ Hold monthly strategy call to review results and next steps ☐ Review and optimize active campaigns/services ☐ Check in on client satisfaction (NPS or informal check) ☐ Identify upsell or expansion opportunities ☐ Update internal SOPs based on lessons learned ☐ Review contract renewal date (flag 60 days before expiry)
Best Practices
- Turn this checklist into an SOP template in your project management tool (Asana, Monday, ClickUp, etc.)
- Assign a specific team member to own each onboarding — accountability prevents things from falling through
- Deliver a 'quick win' in the first week to build immediate confidence and momentum
- Use the kickoff call agenda as-is — clients appreciate structure and professionalism
- Review and improve your onboarding process quarterly based on client feedback
