The key difference: an online fiscal register is software with no hardware and a monthly fee, while a classic register is a physical device you buy and service. For service businesses, small firms and flat-rate entrepreneurs, online is almost always cheaper and simpler.
Comparison table
| Criterion | Online (software) | Classic (device) |
|---|---|---|
| Hardware | Not needed, runs on your device | A dedicated device is bought |
| Cost | Monthly subscription (from ~€9) | Purchase + servicing |
| Setup | Active in minutes | Procurement and configuration |
| Updates | Automatic, on the server | Manual / via a technician |
| Works offline | Needs internet (V-PFR) | Offline possible (L-PFR device) |
| Best for | Services, small firms, field work | Large retail |
When online is better
When you want a small, predictable cost, work in the field or from an office and do not need a drawer-and-scale register - that is most service businesses.
When a classic register makes sense
A device (L-PFR) can make sense in large retail with heavy traffic, where offline operation and scale integration matter. For services it is overkill.
Key takeaways
- Online: no hardware, cheaper, active in minutes
- Classic: a device, purchase and servicing, for large retail
