Zervant invoicing software is a robust web application that relies on browser features that only full-fledged Windows/MacOS/Linux browsers can offer. For this reason, there may be some unexpected issues when it's used within a mobile browser.
However, we do offer a mobile app for Android and iOS. You can download it from Google Play Store or Apple App Store. Read more here of what is currently available on it. We are also constantly working on the app to offer more features in the future.
