Client onboarding is one of the most important moments in the agency-client relationship, and one of the most commonly botched. Somebody forgets to send the welcome email. The project folder is set up wrong. The kickoff call happens without the brief being shared. The client’s first impression of your delivery is disorganised.
The fix is not a better checklist. It is automation. When the proposal is signed, everything that needs to happen should happen automatically, with humans only stepping in for the parts that require judgement.
Here is how to build it.
What onboarding actually involves
Before you automate anything, map out every step in your current onboarding process. For most agencies, it looks something like this:
- Proposal signed / deposit paid
- Welcome email sent to client
- Project folder created (Google Drive, Dropbox, or Notion)
- CRM updated (deal moved to “Active”)
- Internal Slack channel created
- Project created in PM tool (Asana, Monday, ClickUp)
- Kickoff call scheduled
- Brand assets and logins requested from client
- Discovery brief shared
- Team assigned and notified
Most agencies do all of this manually. It takes 2-3 hours per new client and something always gets missed. With automation, the human effort drops to about 20 minutes: reviewing what the system has set up and adding the context that only a person can provide.
The trigger
Every automation needs a trigger. For onboarding, the cleanest trigger is the proposal being signed or the deposit hitting your account. If you use a tool like PandaDoc, Proposify, or HubSpot for proposals, the “proposal signed” event is your starting point.
If you use Stripe or GoCardless for payments, the “payment received” webhook works just as well.
This single event kicks off the entire chain.
The automated sequence
Here is what fires automatically once the trigger event occurs:
Step 1: CRM update
The deal moves from “Won” to “Onboarding” in your CRM. The close date is recorded. The project value is logged. If you are tracking revenue by month, this feeds your reporting automatically.
Step 2: Welcome email
A templated email goes to the client. It includes: a thank you, what happens next, a link to schedule the kickoff call (Calendly or Cal.com), and a request for brand assets and logins via a simple form (Typeform or Tally works well).
This email should feel personal. Use merge fields for the client name, project type, and account manager name. Nobody needs to know it was automated.
Step 3: Internal notifications
A message fires in Slack (or Teams) tagging the delivery team: “New client onboarded: [Client Name]. Project: [Project Type]. Kickoff link sent. Assets pending.”
The project lead knows immediately. No waiting for someone to forward an email.
Step 4: Project setup
A project template is duplicated in your PM tool with the client name, standard phases, and default task assignments. If you use Asana, Monday, or ClickUp, all three support template duplication via API or through automation tools like Make or Zapier.
Step 5: Folder creation
A project folder is created from a template structure in Google Drive or Notion. Subfolders for briefs, assets, deliverables, and feedback are ready before the team even opens the project.
Step 6: Follow-up sequences
If the client has not submitted their brand assets within 48 hours, a gentle reminder goes out automatically. If the kickoff call has not been booked within 72 hours, another nudge is sent. These follow-ups run until the actions are completed, then stop.
Building it in practice
You do not need to build all of this at once. Start with the highest-value piece and expand.
Week 1: Set up the trigger (proposal signed) and automate the welcome email and CRM update. This alone saves an hour per new client and eliminates the “someone forgot to update the CRM” problem.
Week 2: Add project and folder creation. Use your PM tool’s API or a pre-built integration to duplicate a template project.
Week 3: Add the Slack notification and follow-up sequences.
Week 4: Review, refine, and document the workflow so the whole team understands it.
The entire system can be built in Make, Zapier, or n8n. Make is particularly good for this because onboarding involves multiple branching steps and data transformations.
What stays manual
Not everything should be automated. These parts still need a human:
- The kickoff call itself. This is relationship-building. A human leads it.
- Reviewing the brief. AI can generate a first draft from the proposal and discovery call notes, but a strategist should review it before it goes to the team.
- Team assignment. Who works on this project depends on capacity, skill fit, and client chemistry. Automation can suggest based on availability, but the final call is human.
- Tailoring the approach. The standard template gets you 80% of the way. The last 20% (adjusting timelines, adding bespoke phases, flagging risks) requires experience.
The result
Agencies that automate onboarding consistently see three things:
- Faster time to kickoff. From days to hours. The client signs and everything is moving before they have finished their coffee.
- Nothing gets missed. The checklist runs itself. No more “did anyone set up the Drive folder?” messages in Slack.
- Better first impressions. Clients notice when an agency is organised from day one. It sets the tone for the entire relationship.
If your agency automation strategy needs a starting point, onboarding is one of the best. It is repeatable, it touches every client, and the ROI is immediate.
