The worst time for a shop computer to fail is the second Saturday in December. A queue at the counter, a frozen screen and a customer holding three gifts. It happens every year to someone.

Most of those failures are preventable. A short technology check now, while trade is still manageable, can save a lot of stress later. None of it needs technical skill.

Restart your computers

Computers that run for weeks without a restart slow down and become unreliable. Memory fills up, background processes pile up and updates sit waiting. Restart your POS computers at least once a week, ideally at close of trade. It takes a few minutes and solves more problems than you might expect.

Deal with the dust

Shop computers often live under counters, near doors and close to stock. Dust builds up inside, blocks airflow and causes overheating. Overheating shortens hardware life and causes random crashes. With the computer turned off, check the vents and fans. A can of compressed air does the job. Keep the machine off the floor where you can.

Install updates

Operating system updates are annoying. They arrive at inconvenient times and ask for a restart. But many of them fix security weaknesses that criminals actively look for. The same applies to your POS software. Running an old version means missing security patches and compliance changes. If you’re not sure which version you’re on, ask your software provider.

Check your backups

If you’ve never tested a backup, you don’t really know it works. Make sure your data is backed up automatically, stored off-site or in the cloud, and that you know how to restore it. Ask yourself: if this computer died tonight, how quickly could I trade tomorrow?

Look at your network gear

Modems, routers and switches sit quietly in the back room until they stop working. Older equipment can drop connections, slow down card payments and leave security gaps. If your network hardware is more than five or six years old, it may be worth replacing before the busy season, not during it.

Basic cyber security

Use strong, unique passwords. Turn on two-factor authentication for email and banking. Teach staff not to click links in unexpected emails, especially ones about invoices or deliveries. Small retailers are targeted because criminals assume they’re less prepared.

Know who to call

When something does go wrong, a good help desk call starts with clear information: what happened, any error message, what you were doing at the time and which computer is affected. A photo of the screen helps. Keep the support number somewhere every staff member can find it.

What to do this week

Block out one hour after close. Restart every computer, clean the vents, run updates, confirm your last backup and write the help desk number on a card at each register.
