Keep selling when the network goes off

It always happens at the worst time. The market is busy, there is a queue at the counter, and the network bars on your phone drop to nothing. Or the lights go off and the shop's router goes dark with them. Customers still want to buy, and you still want to sell.

Outages are part of doing business in many places, so the smart move is to plan for them before they happen. This guide covers the simple habits that keep your records accurate when the network or power fails, and what happens to sales you record offline once the connection returns.

Why outages cause lost money

An outage rarely costs you the sale itself. Customers are patient, and cash still works. What it costs you is the record. In the rush, a sale goes unwritten, a credit purchase is "remembered" instead of noted, or a Mobile Money payment is accepted without being checked. A week later, the stock does not match the sales, the cash is short, and nobody can say why.

So the goal during an outage is simple: every sale still gets recorded, once, with the right amount and the right payment method. Everything below supports that one goal.

Keep your phone and printer charged

If your till is a phone, then a flat battery is a closed shop. A few habits make a big difference:

• Keep a charged power bank at the counter, and charge it again every night.
• If outages are long in your area, consider a small solar charger or a battery that can power a phone and a receipt printer for a full day.
• Turn down screen brightness and close apps you do not need while the power is off.
• Charge your Bluetooth receipt printer whenever the lights are on. It is easy to forget, because it usually sits in a corner doing its job.

Use an app that works offline

Not every sales app keeps working when the internet goes. Some stop completely, and staff fall back on scraps of paper. Before you rely on any system, test it: switch on flight mode and try to make a sale.

In Snnel, the point of sale keeps recording sales with no internet. Each sale is saved on the device, and when the connection comes back, the sales sync to your account on their own. Every offline sale carries its own reference, so a sale is not recorded twice if the connection flickers on and off while it syncs. Customers can still get a receipt from a Bluetooth printer, because printing does not need the internet.

Have a paper backup for real emergencies

Sometimes everything fails at once: the phone is dead, the power bank is flat and the queue is long. Keep a simple sales book at the counter for these moments. It is not your main system, just a safety net.

Rule the pages into columns so that anyone can fill it in quickly:

The last column is the important one. When the phone is back, enter each sale and tick it off. That way nothing is entered twice and nothing is forgotten. Write credit sales with the customer's name every time, because debts are the first thing people forget.

Be careful with Mobile Money during outages

A network outage is exactly when payment tricks happen. A customer shows a message on their phone that looks like a payment, but you cannot check your own wallet because there is no signal. Some honest payments are also delayed and only arrive later.

• If you cannot confirm a Mobile Money payment, ask for cash instead, or ask the customer to wait.
• For regular customers you trust, you can record the sale as credit and mark it paid once the money shows in your wallet.
• Never accept a screenshot or a forwarded SMS as proof of payment. Only trust what reaches your own wallet.

Check everything after the outage

When the network and power return, take ten minutes to bring everything back in line. It is much easier now than at the end of the month.

1. Open the app and let any waiting sales sync.
2. Enter any sales from the paper book and tick them off.
3. Check your Mobile Money wallet and match each payment to a sale. Follow up on any that are missing.
4. Count the cash in the drawer and compare it with the cash sales for the day.
5. Glance at stock for your fastest sellers to make sure the numbers look right.

If something does not match, it is far easier to fix the same day, while you and your staff still remember what happened. For a wider routine, see a stock count routine that takes 30 minutes a week.

Train your staff for outage days

An outage plan only works if everyone at the counter knows it. Spend five minutes showing your staff what to do: where the power bank is, how to check the app is still recording, where the sales book lives, and the rule about unconfirmed Mobile Money payments. Then, on a quiet day, switch the phone to flight mode and let them practise one sale. When the real outage comes, nobody panics.

Outages are not going away soon, but with a little preparation they stop being a threat to your records.
