To set up the Booster Credit feature, navigate first to Settings, then to Admin Settings, then scroll down to the Store section. Toggle ON (turn blue) the feature to Enable Booster Credits. Click Save toward the upper right of that section.

Add your Booster Credits in Accounting > New Transactions, and on the dropdown menu under Transaction Type select Booster Credit. There you can select the Member under Add User and enter the amount. Click Save and now this member has the Booster Credits applied to their account. The user's credits can be seen on the web version of BoosterHub by selecting People, then choose the person's name, then scroll to the bottom of their page to select the Booster Credits tab.  

To set up a Product with Booster Credits, navigate to Store, select the Product that you want to make available through Booster Credits, then scroll down in that Product and turn ON the toggle to Enable Booster Credits. This means that at checkout, the user will have the option to pay for the item with Booster Credits.  

When the user goes to your booster club's website and Store, they will select the item and add it to cart. When they go to checkout, they can check the box to Apply Booster Credit.

Booster Credits can only be applied to the first payment of a Pay Later item.
