One thing every business owner loves is revenue continuity. While class packs are typically a one time purchase, on Recess you can set your packages to renew.

In your dashboard go to Products > Subscription/ Package

The creation button is always yellow and at the top right. Create a new package.

Fill out your package details and select "auto-renew after package is used up" at the bottom right.

This will automatically replenish your clients pack once they use their last session, unless they choose to cancel.
