How to keep selling when the network drops

In many of our cities the internet or power drops more than once a day. If your shop's sales system only works online, every outage means one of two things: sales stop while the customer stands in front of you, or you go back to paper and forget to enter it later, so stock and accounts drift apart.

The answer is not to give up on the internet but to use an "offline-first" system: it saves every invoice on the device the moment it is issued, deducts stock and records the payment, then sends it all to the server automatically when the connection returns, without you doing anything.

When choosing a system, ask three questions. Can you issue and print an invoice with the internet down? What happens if two devices sell the same item during the outage? A good system resolves that when it syncs and loses neither sale. And does it run on a phone's battery when the power goes out?

Do not forget local payment methods: cash, credit and transfers through banking apps. A system that does not record credit sales and customer balances sends you back to the ledger, however good it looks.

Finally, ask about your data: can you export all of it whenever you want? It is your shop's record, not the property of the company selling you the subscription.
