In Odoo, tasks are not visible to customers by default due to access rights and portal user restrictions.

 To Make Tasks Visible to Customers (Portal Users):

1. Enable Customer Portal Access:
   • Go to the Customer's contact → enable "In Portal".
2. Share the Project:
   • On the Project form, enable "Customer Visibility" and link the customer in the "Customer" field.
3. Adjust Access Rights (if needed):
   • Go to Settings > Technical > Security > Access Control Lists (ACLs).
   • Add read access to the project.task model for the Portal group.
4. Grant Task Visibility in the Portal:
   • On the task form, set the customer or related project so it reflects under their portal view.

Hi. thank you for your answer. My customer sees 5 tasks and 5 record in the timesheet.
The project has 8 tasks. I tried to remove and recreate => same thing. It is not the first time, so I would like to know if it could be due to my server or the application.

How can I check that ? Logs ?

Hii,

1. Share the Project with the Customer
   The customer must have access to the project itself, not just the task. Go to the project and share it with their portal user.
2. Check Project Privacy Settings
   Make sure the project visibility is set to allow portal users (e.g., “Visible by following customers and invited portal users”).
3. Verify Customer is a Portal User Linked to the Correct Partner
   The customer’s partner must be linked to a portal user and be the same partner added as a follower on tasks.
4. Check Task Visibility and Record Rules
   Ensure no custom record rules block portal users from seeing some tasks, and tasks are not marked internal only.
5. Test with Another Portal User
   Add a test portal user as a follower on the same tasks to confirm visibility issues.
