Yes, you can configure a number series for your subscription item, and every subscription that’s created henceforth with a plan from that subscription item will follow the subscription item’s number series. Here’s how: * Navigate to _Product Catalog_ > _Subscription Items_. * Select a subscription item or click **\+ New** to create a new subscription item. * Click **Edit**. * Mark **Auto-generate Subscription Item Numbers**. * Enter a **Prefix** and **Next Number**. * Click **Save**. The Prefix that you enter will remain constant. However, the Next Number will be incremented by 1 for every subsequent subscription. For example, if your Prefix is Pro and your Next Number is 0001, the subscription numbers would look like: Pro-0001, Pro-0002, Pro-003 and so on. **Note**: If you enable number auto-generation for this subscription item, the subscription number auto-generation, which you’ve configured in Settings will be overridden. Instead, this subscription item’s number auto-generation will be used for new subscriptions that are created with this subscription item. * * *
