Excellent product - Excellent support - Completely Happy.We have been using JustOn as our billing platform for 6 months now and it has performed excellent. We run approximately 2,000 invoices per week with complex tax configurations. The app is flexible, fully configurable, and as solid as they come. It is what you expect and need from a billing solution. My compliments to the developers.But what makes the app a more complete solution is the support that we have received from the Vendor. Each and every interaction with everyone on their team has been five stars. Questions are answered quickly, and the JustOn team often comes up with creative recommendations which we did not think of. I’m very impressed.Thank you for being such a great partner.
