System Requirements
Business Plus Plus runs in a browser. There is no desktop client to install and no per-machine licence to manage, but the browser, the screen and the network all have to clear a reasonable bar.
Browsers
Section titled “Browsers”Use a current release of one of the following. Business Plus Plus targets the two most recent major versions of each.
| Field | Type | Required | Description | Notes |
|---|---|---|---|---|
| Google Chrome | Desktop | No | Fully supported. The reference browser for testing. | Recommended |
| Microsoft Edge | Desktop | No | Fully supported. | Chromium-based releases only |
| Mozilla Firefox | Desktop | No | Fully supported. | |
| Safari | Desktop | No | Supported on macOS 13 and later. | |
| Internet Explorer | Desktop | Read-only | Not supported. The application will not load. | Use Edge instead |
Supported browsers
Display
Section titled “Display”| Field | Type | Description | Notes |
|---|---|---|---|
| Minimum width | Pixels | 1280 px for data entry screens. | Below this, line-item grids scroll horizontally |
| Recommended | Pixels | 1920 × 1080 at 100% scaling. | |
| Reading | Any | Reports and documents are readable on a tablet or phone. | |
| Zoom | Percent | Supported from 80% to 150%. | Browser zoom, not OS scaling |
Screen requirements
Network
Section titled “Network”| Field | Type | Required | Description | Notes |
|---|---|---|---|---|
| Bandwidth | Mbps | No | 2 Mbps per concurrent user for comfortable use. | 5 Mbps if users print large reports |
| Latency | ms | No | Under 150 ms round trip to the application host. | Above 400 ms, lookups feel sluggish |
| Protocol | HTTPS | Yes | Port 443 outbound must be open. | |
| WebSocket | WSS | No | Required for live dashboard updates and print status. | Some proxies block this; the app degrades to polling |
Network requirements
Printing
Section titled “Printing”Install the printer as normal and print from the browser dialog. For pre-printed stationery, set the paper size in Company Settings → Printing to match the form, and switch the browser’s Scale to 100% rather than Fit to page.
Printing works through the standard dialog. Safari respects the page size set in Company Settings; Chrome occasionally needs More settings → Paper size set manually the first time.
Use the Compact print template, available on receipts and delivery notes. Set the printer to 80 mm roll or to the continuous form size, and disable headers and footers in the browser print dialog.
