When we designed our system, we were thinking about YOU the whole time. By interfacing through a single API to connect to multiple point-of-sale systems, you never have to worry about POS integration again. We will manage all updates to the various APIs, new functionality offered, versioning, etc.

    Let us do the dirty work…

    Need to process payments? So do we...

    Want to send payments? Not a problem! We have partnered with various gateways to make this possible using a multiple number of processors/gateways!

    Get the information you need as soon as it is available! No more polling!

    We have created a unique, proprietary Webhook solution developed in-house by our POS experts to bring you information from the POS as soon as it is available. Our solution does not simply poll the POS; instead, we monitor the POS directly for changes/additions and will notify you within seconds of those changes to ensure you are ALWAYS up to date.

    This solution reduces CPU usage for the POS and greatly increases productivity of your application. NO MORE POLLING!
