Why business continuity is about more than keeping the lights on

How the right POS technology, network infrastructure, and contingency planning can help keep your business operating.

A Power Outage Got Me Thinking

Today, the electricity went out in my area. The businesses next door to me were also out of power, and the electric company said it might be up to 6 hours before power comes back on.

Like a lot of people dealing with an unexpected lengthy power outage, I found myself sitting in my car, charging my phone and figuring out how to make the most of the situation.

And it got me thinking about something I deal with almost every day in the merchant services industry.

What happens when a business loses power?

Not just for a few minutes, but for two, three, or even six hours.

Imagine a restaurant on a busy Friday evening. The dining room is full, employees are taking orders, the kitchen is preparing meals, and customers are paying their checks.

Suddenly, the electricity goes out.

What happens next?

Can the restaurant continue accepting payments? Can the kitchen receive orders? Can employees clock in and out? Can the business access its sales information?

Or does the entire operation come to a stop?

These are questions every business owner should be asking before an outage happens.

And the answers might surprise you.

Your POS System Is More Than a Cash Register

Years ago, many businesses relied on relatively simple cash registers. They recorded sales, calculated totals, and stored cash.

Today’s point-of-sale (POS) systems are considerably more sophisticated.

Depending on the platform and configuration, a modern POS system may manage:

• Credit and debit card payments
• Cash transactions and sales reporting
• Inventory management
• Employee time cards and scheduling
• Payroll integrations
• Sales tax calculations and reporting
• Kitchen printers and kitchen display systems
• Online ordering and delivery integrations
• Customer loyalty programs and gift cards
• Business analytics and financial reporting

For many businesses, the POS system has become the operational hub.

That’s convenient when everything is working properly.

But it also means a disruption to electricity, internet connectivity, or networking equipment can affect multiple areas of the business simultaneously.

The more your business depends on technology, the more important it becomes to understand what happens when that technology is interrupted.

Power Outages and Internet Outages Are Two Different Problems

One of the first things I explain to merchants is that losing electricity and losing internet connectivity are not necessarily the same problem.

Understanding the difference is essential when developing a contingency plan.

What happens when the electricity goes out?

When a building loses electrical power, equipment connected directly to wall outlets generally stops working unless it has an internal battery or an external backup power source.

That may include POS terminals, kitchen printers, network routers, switches, internet modems, and wireless access points.

Some POS devices have battery capabilities, but the availability and duration vary by manufacturer, model, and configuration.

A system that remains powered on may still lose access to the internet if the modem or router shuts down.

What happens when the internet goes out?

An internet outage presents a different challenge.

Your POS equipment might still have electricity, but it may be unable to communicate with payment processors, cloud-based applications, or online ordering platforms.

Some local functions may continue operating, while others may become unavailable.

The important question is not simply whether your POS system has power.

It’s whether the entire chain of technology required to operate your business is still functioning.

Solution #1: Battery Backup for Critical Equipment

One of the most practical ways to prepare for a power outage is with an uninterruptible power supply, commonly called a Uninterruptible Power Supply or UPS.

A UPS contains a battery that can temporarily provide electricity to connected equipment when normal power is interrupted.

Depending on the equipment’s power requirements and the UPS capacity, it may provide enough time to complete transactions, shut down equipment safely, or continue limited operations.

For example, a business might consider backup power for its:

• POS terminal
• Internet modem or fiber ONT
• Network router
• Essential network switches
• Wireless access points
• Other critical devices

However, battery backup systems are not all created equal.

A UPS capable of running a modem and router for an extended period might provide significantly less runtime when connected to several POS terminals and other devices.

That’s why backup power should be selected based on actual equipment requirements and the amount of time the business wants to remain operational.

A business should also test its backup equipment periodically.

Simply having a UPS installed doesn’t guarantee that its battery is healthy or that it will provide the expected runtime.

Solution #2: Cellular Connectivity as a Backup Internet Connection

Cellular connectivity can be another valuable tool for business continuity.

Some payment terminals include cellular capabilities, while other businesses use cellular routers or gateways to provide backup connectivity for multiple devices.

With a compatible device, an activated cellular service plan, and adequate signal strength, a business may be able to continue communicating with its payment processor even when its primary internet connection is unavailable.

This can be particularly valuable for restaurants, retailers, and service businesses that rely heavily on electronic payments.

But there’s an important distinction.

Cellular connectivity provides an alternative internet connection. It does not automatically provide backup electricity.

If your router, payment terminal, or other essential equipment has no power, cellular service alone won’t solve the problem.

A well-designed contingency plan considers both electricity and connectivity.

Solution #3: Alternative Internet Services, Including Starlink

For some businesses, especially those in rural areas or locations with unreliable traditional internet service, satellite internet may be worth considering.

Services such as Starlink can provide connectivity without relying on the same local wired infrastructure as cable or fiber internet.

That can offer another layer of redundancy.

However, satellite equipment still requires electricity, and service can be affected by equipment, network, environmental, or provider-related issues.

If a business intends to use satellite internet during an electrical outage, the satellite equipment and necessary network components must have a suitable backup power source.

There’s also an important difference between having two internet subscriptions and having a functioning backup system.

For example, a business with both cable internet and Starlink may still experience downtime if nobody knows how to switch between them.

A properly configured dual-WAN router or similar network solution can help manage connectivity between primary and backup internet services.

This is where knowledgeable IT and networking professionals can make a significant difference.

Solution #4: Understanding Offline Credit Card Processing

Many modern POS systems offer some form of offline payment processing. While I don’t recommend taking offline payments for days on end, for short periods of time (and for lower ticket sized businesses), it’s likely a better option than turning customers away or telling them “cash only”.

This feature can allow eligible transactions to be captured locally when the system cannot communicate with the payment processor.

Once connectivity is restored, those transactions can be submitted for authorization and processing.

It sounds like a convenient solution, and in some circumstances it can be.

But there are risks.

An offline payment is not necessarily an approved payment.

If a transaction is declined when it is eventually submitted, the merchant may be responsible for the loss.

Offline capabilities also vary by POS platform, payment method, device, and processor.

Some systems impose transaction limits or time restrictions. Certain payment methods and features may not be supported offline.

Merchants should understand these limitations before relying on offline payments as part of their contingency plan.

Personally, I prefer helping merchants maintain reliable online connectivity whenever possible rather than allowing large numbers of unapproved offline transactions to accumulate.

Offline processing can be a useful backup option, but it should not be confused with guaranteed payment acceptance.

Solution #5: Protect the Entire POS Ecosystem

This is where I believe many businesses overlook the bigger picture.

Keeping a credit card terminal operational is important.

But what about everything connected to it?

Consider a restaurant that uses a POS system to send orders to kitchen printers.

If the POS terminal remains powered but the network switch or kitchen printer loses electricity, the restaurant may still have difficulty processing orders.

The same applies to kitchen display systems, employee time clocks, online ordering integrations, and other connected applications.

That’s why a business-continuity assessment should look beyond the payment terminal.

It should examine the entire technology environment and identify which components are essential for continued operations.

Sometimes the solution isn’t a new POS system.

It might be a better router, a properly sized UPS, a backup internet connection, or changes to the network configuration.

And sometimes the most valuable improvement is simply making sure employees understand what to do when something stops working.

Final Thoughts: Prepare Before the Lights Go Out

Sitting in my car today because the electricity went out wasn’t exactly convenient.

But it reminded me how dependent we’ve all become on technology, both personally and professionally.

For a business owner, that dependency carries additional consequences.

A power outage or network failure can interrupt sales, create confusion for employees, affect customers, and potentially result in lost revenue.

The good news is that there are ways to prepare.

Battery backup, cellular connectivity, secondary internet services, offline payment capabilities, and thoughtful network design can all play a role.

The key is understanding how those solutions fit together.

Sometimes the real value of technology isn’t what it does when everything is working perfectly. It’s what it allows your business to keep doing when things go wrong.
