Usystems is a web-based application that runs in your browser. For the best experience, use a modern, updated browser on a device with a stable internet connection.
Supported browsers
| Browser | Minimum version | Desktop | Mobile | Notes |
|---|---|---|---|---|
| Chrome / Chromium | 90+ | ✓ Recommended | ✓ Supported | Best overall performance; auto-updates |
| Firefox | 88+ | ✓ Recommended | ✓ Supported | Excellent compatibility; auto-updates |

Recommended setup
For desktop (primary work):
- Use Chrome, Firefox, or Safari on a laptop or desktop computer.
- Ensure your browser is set to auto-update so you stay on a current version.
- Use a wired or strong wireless internet connection (minimum 2 Mbps).
For mobile/tablet (reference and simple tasks):
- Use Chrome, Safari, or Firefox on a smartphone or tablet (iOS, Android).
- Usystems works on mobile but is optimized for desktop screens—entering large invoices or completing complex reports is more difficult on small screens.
- For frequent mobile use, consider a tablet rather than a phone.
Minimum device requirements
| Aspect | Requirement |
|---|---|
| RAM | 4 GB (8 GB recommended for heavy use) |
| Screen width | 768 px minimum (1024 px recommended for full comfort) |
| Internet speed | 2 Mbps stable connection |
| Processor | Any modern CPU (2015 or newer) |
| Storage | Browser cache only (no app download needed) |
Unsupported browsers
The following browsers are not supported and may not work correctly:
- Internet Explorer (all versions)
- Opera Mini
- Outdated versions of any browser (more than 2–3 major versions old)
- In-app browsers on social media platforms (Facebook, WhatsApp, etc.)
Tips for best performance
- Keep your browser updated: enable automatic updates to ensure security and compatibility.
- Clear browser cache regularly: if you notice slow performance, clear your browser's cache and reload the page.
- Use a private/incognito window if you have issues: sometimes cached data causes problems; a fresh session helps.
- Check your internet connection: a weak connection will make Usystems feel slow even on a supported browser.
- Close unused tabs: running many browser tabs simultaneously consumes memory and may slow Usystems.
- Use a desktop for heavy work: for tasks like invoice entry, reports, or multi-day workflows, a desktop or laptop is more comfortable than mobile.
