How to Choose Locked or Editable Serial Numbers
Choose Locked when the serial selected for the layaway must stay assigned to that customer. Choose Editable when staff may assign or replace the serial later.
Locked serials work well for holding a specific used or one-of-a-kind device. Editable serials work well for preorders, prepaid sales, or products fulfilled from later stock. Save the setting, then make sure staff understands when the physical device becomes committed.
