There are three possible user types in Pipedrive: Deals access, Account settings, and Viewer access. Each gives users access to different features and functionality within Pipedrive.
Access rights can be configured by going to Company settings > Manage users. From here, you will be able to see the access type for each user in your company account.
Deals access allows you to use Pipedrive's core sales functionality. By having access to Deals you will have access to your pipeline, leads, deals, contacts, and all related features.
Account settings access rights give you the ability to view and edit your company billing details, security settings, company settings, user management, and personal settings. You will not have access to Pipedrive's core sales functionality without also having Deals access.
This does not require a paid seat, as users in this role will not have access to most Pipedrive features. It is particularly useful for any person managing the subscription and billing information.
Pipedrive's Viewer feature allows you to share a read-only version of your pipeline with anyone outside of your company account. By default, only admin users will be able to share pipelines. Regular users can share pipelines if they have permission from the admin user.
