Keeping Your POS Online: Routers, Power Cuts and Backups

The two things most likely to stop service in a Kenyan restaurant are a power cut and a dropped connection. Both are cheap to plan for.

Restaurants worry about choosing the right software and then lose a Friday night to a router. In Kenya, uptime planning is not an afterthought - it is part of the setup.

Power

A mains-powered terminal, printer and router all stop together in a cut. A UPS keeps them running long enough to either finish service or shut down properly.

What to size it for: your till, your router and your receipt printer. Not the fridge. A 1200VA unit typically covers a small setup for a useful stretch - enough to get through a short outage without turning customers away.

Tablets have their own batteries, which is a genuine advantage during outages. Many restaurants keep one charged tablet as their fallback till.

Internet

Two rules. First, use a proper router, not a phone hotspot, once you have more than one device. A till, a kitchen screen and a printer all fighting over a phone connection is a bad evening waiting to happen.

Second, have a fallback. A mobile router or a phone you can tether from costs little and turns a broken fibre line into an inconvenience rather than a closure.

What happens when you do drop

Ask any POS vendor this question directly and listen carefully to the answer: what exactly can my staff still do if the internet goes down mid-service? The honest answers vary a lot, and it is far better to know beforehand than to discover it at 8pm on a Saturday.

A simple resilience checklist

  • UPS on the till, router and receipt printer
  • A real router, not a hotspot
  • A mobile data fallback ready to switch to
  • One charged tablet as a backup till
  • Kitchen printer on the network rather than Bluetooth
  • Staff who know what to do for ten minutes without the system

None of this is expensive. All of it is cheaper than sending a full restaurant home.
