From the Cart tab, tap + Add Ref # to add a reference number or transaction note to the sale.
Note: A reference number can be any alphanumerical combination up to 64 characters. Merchants may use this feature to add a short note/invoice number or any relevant information they would like to have associated with the transaction.
Important note:
The reference number is an internal merchant facing note that will be displayed in the Transaction History table and also on the Transaction Details page after a transaction.
Reference numbers are not auto-generated by SwipeSimple but can be enabled to appear on Digital Receipts via Account Settings > Receipts.
