To grant a customer a free month, two steps are necessary. First, you have to create a 100% discount, which is unlocked for the plan variant of the customer. To create a discount go to "Products > Discounts > Create Discount". Create a discount as follows: [![](https://cdn.document360.io/b84e1b5d-2ba6-4465-8c62-fb45a2f31314/Images/Documentation/100 red.png)](https://support.billwerk.com/hc/article_attachments/360026169280) Then go to the customer's contract details (Customer > Contract ID) and click on ''Discount Subscriptions''.
