Most POS buying advice focuses on features. In practice, the decision that costs or saves you the most over five years is quieter: which devices is this software allowed to run on? A cross-platform POS removes the vendor from that decision entirely.
Key takeaways
- Hardware lock-in is where POS costs hide — proprietary terminals and iPad-only systems.
- SeroPOS runs natively on Windows, macOS, iOS and Android from their respective stores.
- Mix device types per station: PC at the counter, tablets tableside, a phone for the owner.
- A failed till is a same-day local replacement, not a support ticket.
- Everything syncs on one account; on a LAN, terminals can share one database.
The hardware trap
Three common versions of it:
Proprietary terminals. Clover devices run Clover, at $799–$2,498 apiece. When you leave the platform, the hardware doesn't come with you.
Single-platform apps. TouchBistro is iPad-only. If an iPad fails on a Saturday, your replacement is another iPad — you can't press a spare Windows laptop into service.
Vendor hardware bundles. Toast sells its own devices; leaving means replacing all of them.
Each is defensible on its own terms. Collectively they mean the vendor, not you, decides your hardware budget.
What running everywhere actually buys you
Cheap replacement. A till dies mid-service; you install the app on whatever spare device is in the building — a laptop, a personal tablet, a phone — sign in, and keep trading. That's the difference between fifteen minutes and a lost night.
Reusing what you own. Most businesses already have a PC and a tablet or two. A cross-platform POS makes those your terminals instead of a purchase order.
Right device per station:
| Station | Best device | Why |
|---|---|---|
| Main counter | Windows PC | Speed, peripherals, big screen |
| Tableside | Android tablet or iPad | Portable, light |
| Kiosk | Any tablet in a locking stand | Kiosk mode |
| Kitchen | Tablet or monitor | KDS app |
| Owner | Phone | Live sales from anywhere |
Scaling cheaply. A second till is a $300 tablet, not a $1,500 terminal plus a monthly per-device fee.
How SeroPOS handles it
Native apps on all four platforms, distributed through the App Store, Google Play, Microsoft Store and Mac App Store — the same product, the same account, synced. Which means:
- Staff learn one interface regardless of the device in front of them
- An order started on one device can be finished on another
- Server/client mode lets several terminals share one database on your local network
- Standard ESC/POS printers, scanners and cash drawers work across all of them (hardware guide)

The five-year hardware maths
A two-till restaurant, over five years:
| Proprietary terminals | Cross-platform on your devices | |
|---|---|---|
| Initial hardware | $2,000–$5,000 | $0–$700 |
| Replacement (one failure) | $800–$2,500 + wait | $300, same day |
| Adding a third till | $800–$2,500 + monthly fee | $300 |
| Value when you switch POS | $0 — locked | Devices remain useful |
The last row is the one people forget. Hardware that only runs one vendor's software has no residual value the moment you outgrow that vendor.
What to check before buying
- Does it run on the devices I already own?
- Can I buy a replacement device locally, today?
- Are there per-terminal software fees?
- Do standard ESC/POS printers work, or only vendor models?
- If I leave in three years, what hardware is wasted?
The principle
Choose software on merit; keep hardware generic and replaceable. That way every future decision — including leaving whatever you pick today — stays cheap.
