Sometimes, you might need to adjust a Loyalty balance. For example, you might have given a customer the wrong amount of Loyalty. You can create and use a Loyalty adjustment product to manage this. To do this, follow the steps below:
Create a new product for "Loyalty". Give it a name like "Loyalty Points" or "Custom Loyalty".
It should have zero supply, retail and tax. However, when you get to the Loyalty section, give it a custom value of $1.
Also, disable Stock Tracking (at the bottom of the page).
Start a new sale. Add the customer to whom you're issuing the loyalty to.
Add the Loyalty product you had created earlier (Step 1). Alter the quantity to the amount of Loyalty you want the customer to receive. E.g., a quantity of 20.5 will give the customer $20.50 Loyalty.
Hit pay and use cash as the payment type - as that's the simplest workflow for a $0 sale. If you check your customer, you'll find they now have the Loyalty points in their account.
