This article is designed to be instructional and step-by-step, so you can both understand the logic and confidently adapt the template in your own n8n instance.
Workflow Overview
The automated client onboarding workflow is built in n8n and connects several common SaaS tools:
- n8n Webhook to receive client form submissions
- Email verification service to validate client emails
- Google Sheets for centralized client logging
- Trello for Customer Success task management
- Slack for internal notifications
- Gmail (or another email node) for client communication
- Airtable for structured storage and reporting
- PDF generation for personalized Welcome Packs
The goal is to move from a manual, error-prone onboarding process to a fully automated pipeline that starts with a form submission and ends with weekly reports for your leadership team.
Core Capabilities of the Template
Key Automation Features
- Client Onboarding Webhook – receives client details from your onboarding form and starts the workflow.
- Email Validation – checks the authenticity of the email to filter out spam or invalid entries.
- Automatic Tier Assignment – maps client plans (Free, Pro, Enterprise) to onboarding tiers (Basic, Standard, Premium) and sets priority.
- Client Logging in Google Sheets – keeps a live, shareable record of all onboarding clients.
- Trello Task Creation – creates onboarding task cards for Customer Success Managers with clear next steps.
- Personalized Welcome Pack PDF – generates a custom PDF with client details, plan, priority, and onboarding ID.
- Internal & Client Notifications – notifies your team in Slack and sends a welcome email with the PDF attached to the client.
- Data Archiving in Airtable – stores all onboarding data for reporting and auditing.
- Weekly Reporting – compiles weekly onboarding stats from Airtable and emails a summary to management.
How the n8n Workflow Runs: Step-by-Step
In this section, we will walk through the full onboarding flow as it happens inside n8n, from the first client form submission to the weekly summary email.
Step 1 – Start With a Webhook and Validate the Email
The automation begins when a new client submits your onboarding form. The form is connected to an n8n Webhook node, which receives fields such as:
- Client name
- Email address
- Selected plan (Free, Pro, Enterprise)
- Any additional onboarding details you include
As soon as the webhook receives the data, the next node in the flow calls an email verification service. This service checks whether the email address is valid and can be used for communication.
In practice, the workflow does something like this:
- If the email is valid, the execution continues to the next steps.
- If the email is invalid, the workflow stops or can be routed to an error-handling branch, which prevents fake or mistyped signups from entering your system.
This early validation keeps your CRM, sheets, and tools clean and avoids wasted time on bad data.
Step 2 – Log the Client and Assign Tiers in n8n
Once the email passes validation, n8n moves on to two key operations that happen in parallel logic:
- Client Logging in Google Sheets
- Tier and Priority Assignment
2.1 Log the Client in Google Sheets
An n8n Google Sheets node writes the client data into a dedicated sheet. Typical columns might include:
- Client name
- Selected plan
- Onboarding tier
- Priority level
- Onboarding ID or reference
- Timestamp
This creates a live, centralized view of all onboarding clients that can be shared with your team without giving them direct access to n8n.
2.2 Use Code-Based Logic to Assign Tiers
At the same time, a Function node or similar logic node evaluates the client’s selected plan. The logic maps plans to onboarding tiers and priority levels. A common setup is:
- Enterprise plan → Premium onboarding tier with high priority
- Pro plan → Standard onboarding tier with medium priority
- Free plan → Basic onboarding tier with lower priority
The workflow attaches these computed values to the client data, which will be used in later steps such as Trello card creation, PDF generation, and Airtable storage.
Step 3 – Create Trello Tasks and Generate the Welcome Pack PDF
With the client data enriched and stored, the workflow now focuses on making onboarding actionable for your Customer Success team and clear for the client.
3.1 Create a Trello Card for the CSM Team
An n8n Trello node automatically creates a card in your Customer Success or onboarding board. The card typically includes:
- Card title: Client name and plan
- Description: Key onboarding details, assigned tier, and any internal notes
- Labels or lists: Reflecting the onboarding tier or status (for example, “Premium”, “New”, “In progress”)
- Due dates or checklists: Optional, to guide the CSM through the onboarding steps
This ensures that every valid signup immediately appears as a task for the responsible team, without manual data entry.
3.2 Generate a Personalized Welcome Pack PDF
In parallel or right after Trello card creation, the workflow triggers a PDF generation step. Using the client data and assigned tier, n8n generates a customized Welcome Pack that can include:
- Client name
- Selected plan and onboarding tier (Basic, Standard, Premium)
- Priority level
- Onboarding ID or reference number
- Key steps for getting started
The PDF node outputs a file link or binary data, which the workflow will later attach to the client email and store in Airtable. This document sets expectations and gives the client a professional, personalized starting point.
Step 4 – Notify Your Team and Welcome the Client
After the Welcome Pack PDF is generated, the workflow moves into communication mode, targeting both your internal team and the client.
4.1 Internal Slack Notification
An n8n Slack node sends a message to a chosen channel, such as #new-clients or #onboarding. The message usually includes:
- Client name and email
- Selected plan and onboarding tier
- Onboarding ID
- Link to the Trello card or Google Sheets row
This instant notification keeps the team aligned and ensures that high-priority clients are seen and handled quickly.
4.2 Send the Welcome Email With PDF Attachment
Next, a Gmail node or similar email node sends a personalized welcome email to the client. The email typically:
- Greets the client by name
- Mentions their selected plan and what to expect from onboarding
- Includes the Welcome Pack PDF as an attachment
- Provides links or instructions for the first steps inside your product or service
This step turns the automation into a client-facing experience that feels tailored, even though it is fully automated in n8n.
Step 5 – Archive All Onboarding Data in Airtable
To keep your data structured and ready for reporting, the workflow then archives the onboarding record in Airtable.
An n8n Airtable node creates a new record that typically includes:
- Client name and email
- Selected plan and assigned onboarding tier
- Priority level
- Onboarding status
- Link to the Welcome Pack PDF
- Links or IDs for Trello and Google Sheets entries
- Timestamps and any additional metadata
This Airtable base becomes the single source of truth for all onboarding-related data, which is especially useful for audits, long-term reporting, or integration with other tools.
Step 6 – Generate Weekly Onboarding Reports
The final part of the template focuses on management reporting and ongoing visibility.
6.1 Scheduled Weekly Trigger
A Schedule node in n8n is configured to run once a week. When triggered, it starts a separate branch of the workflow dedicated to reporting.
6.2 Pull Data From Airtable
The workflow uses an Airtable node to fetch all relevant onboarding records for the reporting period. This might include all clients onboarded in the last 7 days or all clients with a specific status.
6.3 Calculate Key KPIs
A data processing node, such as a Function or Aggregate node, calculates key onboarding metrics, for example:
- Total number of new clients onboarded
- Distribution by plan (Free, Pro, Enterprise)
- Distribution by onboarding tier (Basic, Standard, Premium)
The result is a concise snapshot of your onboarding performance for the week.
6.4 Email the Report to Management
Finally, a Gmail or email node composes an email with the weekly stats and sends it to your management or leadership distribution list. The email can include:
- Summary counts and percentages
- Highlights of higher tier or Enterprise onboardings
- Optional CSV or attached report files generated from the Airtable data
This ensures that stakeholders stay informed without having to log into Airtable or n8n directly.
