  • Works on any phone camera, or a handheld scanner if they have one
  • Scans your competitors’ barcode labels too*
  • Customers and employees can place orders 24 hours a day, even after hours, and the orders will be waiting for you when you get there in the morning. You can choose to be notified every time an order is placed, whether you’re at the office or not. It gives you greater visibility into your company’s ordering activity.

* Simply cross the number in the system to ours, and we can walk you through the process.
