Deconovo US

The interface is well made. Easy to set and to customize. The developpers have tought a lot about the UI and UX. What I appreciate best is their support, top notch. The app still need to improve many aspects on the upsell parts to fit most case scenarios but for our use, it is beyond expected. The dev team said they are working on their roadmap to add more features and the team seem open to more customization.
