In Bitrix24, you can control who can manage Inventory management settings, the product catalog, and access permissions. This helps separate responsibilities. For example, a supervisor can manage catalog settings and permissions, while managers work only with products and documents.

To configure access:

1. Go to the CRM section > Settings > Inventory access permissions.
2. Grant the permissions employees need:

• Section parameters: allows users to update VAT settings, enable subscriptions for out-of-stock items, and manage inventory modes. This permission is typically used by supervisors or inventory managers.
  Inventory management settings
• Edit employee access permissions: allows users to assign roles and grant permissions. For example, a supervisor can assign the Manager role and allow product editing.
  Inventory access permissions
• Toggle the option "Make out-of-stock items available for purchase" on or off: allows users to enable or disable purchases for items that are not currently in stock. This lets customers place pre-orders when needed.

Save your changes. Employees with the required permissions can now manage catalog settings, inventory options, and access permissions.
