## Introduction
Managing shared task boards with clients is a common requirement for startups, agencies, and operations teams. Asana’s Client Access feature simplifies sharing project tasks and status updates with external clients in a controlled environment. However, Asana’s pricing for Client Access can quickly become expensive, especially for growing teams. In this guide, we’ll explore how to replicate a shared client task board using n8n, an open-source workflow automation tool, combined with Google Sheets and Slack or email, to create a cost-effective, flexible alternative. This solution benefits project managers, automation engineers, and startup teams by reducing costs, enhancing customization, and maintaining full control over client access to project updates.
## Use Case Overview
**Problem:** Share real-time task updates and project progress with clients without giving them full access to internal project management platforms or incurring expensive client licenses.
**Benefits:**
– Control client visibility on a need-to-know basis
– Automate task updates without manual effort
– Reduce SaaS subscription costs
– Customize data presentation based on client needs
**Tools & Services Integrated:**
– n8n (workflow automation)
– Google Sheets (shared task board as a client-accessible sheet)
– Slack (for internal team notifications) or Email (client notifications)
– Optional: Google Drive for file attachments

## Technical Tutorial: Building a Shared Client Task Board Automation with n8n
### Step 1: Setup Your Google Sheet as a Shared Client Task Board
– Create a new Google Sheet titled “Client Task Board – [Project Name]”.
– Define columns such as Task ID, Task Title, Description, Status, Priority, Assigned To, Due Date, and Last Updated.
– Share this Google Sheet with your client email with ‘Viewer’ or ‘Commenter’ access to restrict modifications.
### Step 2: Prepare Your Internal Task Management System
– If you are currently using Asana or another PM tool internally, ensure you can access task data via API or export.
– For this tutorial, we’ll assume task updates are manually or programmatically input into a team’s internal spreadsheet or database.
### Step 3: Configure n8n Workflow Trigger
– In n8n, create a new workflow.
– Select a trigger node, for example:
– Time Trigger (e.g., every hour) to sync updates periodically.
– Webhook Trigger if pushing updates in real-time.
### Step 4: Fetch Internal Task Data
– If using Google Sheets to manage internal tasks:
– Add a Google Sheets node to read rows from your internal task sheet.
– If using Asana or another API:
– Use the HTTP Request node to query tasks filtered by active status, assigned user, or priority.
### Step 5: Transform and Filter Task Data
– Use the Function or Set node to transform data, filter tasks updated since last sync, and prepare data for client consumption.
– Ensure sensitive/internal-only fields are removed.
### Step 6: Update Client-Facing Google Sheet
– Use the Google Sheets node to update the client’s shared sheet.
– Key actions:
– Append new tasks
– Update existing tasks (match by Task ID)
– Clear removed tasks if necessary
– Be mindful of Google Sheets API rate limits; implement pagination or batch updates as needed.
### Step 7: Notify Internal Team or Clients
– For internal reminders or status checks, use a Slack node to post summary updates.
– For client notifications about major task changes, use the Email node (SMTP or Gmail) to send digest emails.
### Step 8: Error Handling and Logging
– Utilize the Error Trigger node in n8n to capture failures.
– Log errors to a dedicated Google Sheet or send Slack alerts to admins.
– Add retries on API requests to handle transient errors.

## Detailed Workflow Node Breakdown
1. **Trigger (Cron / Webhook):** Initiates the automation either at a scheduled interval or on-demand.
2. **Get Internal Tasks (Google Sheets / HTTP Request):** Retrieves the latest internal task data.
3. **Function (Data Processing):** Filters and formats data, stripping internal-only info.
4. **Google Sheets (Update Client Sheet):** Writes the processed task data into the client-shared Google Sheet, ensuring synchronization.
5. **Slack / Email (Notifications):** Sends updates to internal team channels or clients.
6. **Error Handling Nodes:** Catches and notifies about issues.

## Tips for Robustness and Scalability
– **Incremental Sync:** Store the timestamp of the last successful sync in a variable or external file. Fetch only tasks updated since then to optimize API usage.
– **Data Validation:** Ensure data integrity before writing to the client sheet; handle empty or malformed entries gracefully.
– **Access Control:** Use Google Sheet permissions wisely to prevent clients from editing beyond intended scope.
– **Audit Trail:** Maintain a change log of updates sent to clients for troubleshooting.
– **Scaling:** For multiple clients, parameterize the workflow to run per client or create child workflows.
—
## Common Issues and Troubleshooting
– **Google Sheets API Rate Limits:** Batch updates in chunks of 50-100 rows, pause between batches.
– **OAuth Token Expiry:** Regularly refresh credentials or use service accounts.
– **Late Data Propagation:** Schedule workflows during low usage periods for faster sync.
– **Data Conflicts:** Implement locking mechanisms or timestamp checks before overwrites.

## Summary
By leveraging n8n alongside Google Sheets and notification tools like Slack or email, you can build an efficient, automated shared task board for clients without the ongoing costs associated with Asana’s Client Access feature. This approach empowers teams with control, flexibility, and transparency while keeping clients informed in near real-time. Additionally, the open-source nature of n8n and Google Sheets offers limitless customization to tailor the workflow as your startup scales.
## Bonus Tip: Enhance with Client-Friendly Dashboards
For a more polished client experience, extend this automation to push task data into Google Data Studio or another BI tool connected to your client Google Sheet. This lets you craft visual dashboards with charts and timelines, refreshing automatically as n8n updates the underlying data. Clients receive an intuitive overview without changing the core automation.
