Hope it helps

Step 1: Understand What "Third-Party Software" Means in Odoo

• In Odoo, third-party software usually refers to community modules or custom apps created by other developers.
• These are not included in the official Odoo core or App Store by default.
• You need to manually download, install, and configure them.

Step 2: Download the Third-Party Module

• Find the module on platforms like:
  • apps.odoo.com
  • GitHub
  • Private developer sites or partners
• Download it as a ZIP file or clone it using Git.

Step 3: Place the Module in the Correct Directory

• Move or extract the module into your Odoo’s addons folder.

🔍 Typical paths:

• Default addons: /odoo/odoo-server/addons
• Or a custom directory like /opt/odoo/custom_addons

Step 4: Update the addons_path in the Config File

• Open your odoo.conf file.
• Make sure the path to your custom or third-party addons is listed under addons_path.

Step 5: Restart the Odoo Server

• After placing the module and updating the config, restart your Odoo service so it can detect the new module.

Step 6: Update Apps List

• Log in to Odoo
• Activate Developer Mode:
  • Click your name (top-right corner) → About → Activate Developer Mode
• Go to Apps
• Click "Update Apps List"
• Confirm when prompted

Step 7: Search and Install the Module

• After updating, search for your module by name in the Apps screen.
• Click Install to add it to your Odoo instance.

✅ Step 8: Test the Functionality

• After installation, test the module to ensure it works as expected.
• Review any menu changes, configurations, or access rights it may add.
