Can the module be restricted to a customer group?

You can use PrestaShop’s authorized modules for customer groups to hide the module’s links from certain groups. This setting does not fully prevent customers from requesting or creating a quote.

1. Under Shop Parameters > Customer Settings, open the Groups tab.
2. Edit the relevant group and find Authorized modules.
3. Disable the quote module for that group, save, then check the storefront links while signed in as a customer in that group.

For a customer belonging to several groups, check every group: the links remain visible if any of their groups authorizes the module, even if their default group does not.

Hiding links does not block direct access. A customer whose group does not authorize the module can still open the simple form directly by its URL and submit a request. With their cart and addresses, they can also open the quote form directly by its URL and save their quote. The group restriction does not prevent the merchant from finding this customer and creating a quote for them in the back office either.

Also check the Visitor and Guest groups if your shop uses them. Both a visitor who is not signed in and a guest customer can access the simple form directly when it is enabled; the structured quote form asks them to sign in to a customer account.

If you need to restrict use of the module to specific customers, have the access controls checked and adapted on your shop.
