Yes, there are user permissions to manage invoices on Cloud. These permissions apply to invoices generated for projects, change orders, subscriptions, service contracts, and service calls.
Go to "Settings > Account > Users & Permissions," and click a user group or a user.
Under the "Invoices" permissions group, you will see 2 permissions:
Create & manage invoices: Allows the user to create and edit invoices. Without these permissions, the invoices are read-only; the users can share and present them.
Delete invoices: Allows the user to delete invoices.
Set one or both permissions to ON for the user or the users in the group.
