If you would like to consistently track customer sales history, demographic information, and more, you'll want to enable customer tracking in the Green Bits Back Office. Here's how:
1. Visit the Settings section in the Green Bits Back Office
2. Visit Store Options
3. Check the box that reads Require Customer Information at Purchase Time
From now on, a transaction cannot be completed until a customer has been selected for the order. Conversely, if you would would no longer like to require customer information, simply uncheck that setting.
