Keeping your business running through a power cut: a systems checklist

Zambia's grid has stabilised through 2026 — ZESCO has ruled out a return to nationwide load shedding — but isolated outages from localised faults or infrastructure damage still happen without warning, and last year's extended power cuts left most business owners with a hard lesson: systems built assuming the lights stay on fail exactly when you need them most.

Start with what actually needs mains power right now. A card machine, a router, a barcode scanner — all dead the moment the power drops. Mobile money doesn't have that problem: Airtel Money and MTN MoMo run over the phone network, so a phone at 20% battery can still take a payment when the till can't. Keep one charged phone and a small power bank behind the counter specifically for this, separate from whatever staff carry around during the day.

The bigger risk isn't the sale, it's the record of the sale. If your point-of-sale or booking system needs a live connection to save a transaction, an outage doesn't just pause you — it creates a gap. Sales taken by hand during a two- or three-hour cut have a way of never making it back into the books cleanly, and a busy afternoon lost that way can easily be 15-20% of the day's transactions. Systems that queue transactions locally and sync automatically once power or connectivity returns close that gap without anyone reconstructing it from memory later.

We build point-of-sale and booking systems with that offline queuing in from the start, so a bad hour on the grid doesn't turn into a bad set of books — the sale is captured locally the moment it happens and synced the moment the connection is back.
