Common questions about using our browser-based online invoice generator.
No installation is required at all. SmartInvoiceGen is a purely online invoice generator that runs in your web browser. There is nothing to download, no plugin to install, and no setup process. Just open the website and start creating invoices. This makes it ideal for shared computers, public workstations, or any situation where installing software is not an option.
Yes, the online invoice generator is fully responsive and works on smartphones and tablets. You can create, preview, and download invoices from your iPhone, Android phone, iPad, or any tablet with a web browser. The interface adapts to smaller screens so all features remain accessible on mobile devices.
Absolutely. SmartInvoiceGen processes everything client-side — meaning all the work happens in your browser, not on a remote server. Your business details, client information, invoice data, and uploaded logos never leave your device. There is no backend database, no cloud storage, and no way for anyone to access your information. It is as private as using a desktop application, but with the convenience of a website.
SmartInvoiceGen requires an initial internet connection to load the page. However, once the page is loaded, all processing continues to work even if your connection drops. Since everything runs locally in the browser, you can keep editing and creating invoices. You will need to reconnect to download the PDF if you are using the PDF generation feature, but you can still do everything else offline.
SmartInvoiceGen works on all modern web browsers: Google Chrome (recommended), Mozilla Firefox, Apple Safari, Microsoft Edge, Opera, Brave, and others. We recommend keeping your browser updated to the latest version for the best performance and PDF rendering quality. The tool uses standard web technologies that are supported by any browser released in the past few years.
