Real-Time Reporting



View all transactions across your business or for specific users. Get transaction-level detail including transaction IDs, amount, date, signatures, SKU, and more.


Easily perform voids and refunds for any past transaction, or re-send copies of receipts to your customers.


Find out what sells (and what doesn’t), at what times, on which dates, and at which locations. Our powerful reporting tools organize purchase data to help you make better business decisions.


Customized Settings



Text or email customers a receipt immediately after their purchase. Or, you can always send a receipt later by viewing past transactions.


Present the customer with a tip screen prior to processing their payment. Select between default tip amounts or enter a custom dollar amount.


Capture swiped or keyed payments even without an internet connection. Offline mode is not compatible with EMV or NFC transactions.


Take your business to the next level.
