The Contacts Approval Addon ensures that all partner records (both customers and suppliers) in the system must be approved before they can be used in any business documents or be searchable. After installation, the addon automatically sets all existing partners as "approved," ensuring they do not need to go through the approval process again. Additionally, unapproved partners cannot be included in sales orders, purchase orders, invoices, or any other transactions, and will not appear in system searches. Once a partner is submitted for approval, an activity notification is sent to the designated approver.
