How Many Spare POS Devices Should a Restaurant Keep?

By Fleksa7 min read•POS Hardware, Restaurant Operations

A spare POS device is worth considering when its failure would stop a critical service task and a replacement would take too long. Use this worksheet to compare practical backups, supplier lead times, and the cost of keeping equipment ready.

Keep a spare POS device when losing the working one would interrupt a critical task, the available workaround is too slow, and a replacement cannot arrive quickly enough. That might mean one spare printer for a busy kitchen, one compatible terminal for a single-register counter, or no extra device at all if another station can handle the work.

Start with the job a device does, not the number of devices you own. A warranty may pay for a repair or replacement under its terms, but it does not necessarily put a working unit in your hands during tonight’s dinner rush. A spare is an operating decision: what interruption can you tolerate, and what does it cost to be ready?

Find the devices with no practical backup

Walk through an order from entry to payment and kitchen handoff. List the physical devices used at each step: counter terminals, handhelds, printers, kitchen displays, and any tablet used for a critical task. Fleksa’s restaurant POS hardware page is a useful starting point for the types of equipment to inventory.

For each device, ask what staff would do if it stopped working at the busiest point of service. Be specific. “Use another terminal” is only a workable answer if that terminal can perform the necessary task, is accessible to the right staff, and has enough capacity to handle the extra queue.

  • Order entry: Can another station take orders without blocking the line or pulling a server away from the dining room?
  • Payment: Is another approved payment setup available, and can staff use it at the required location? A spare screen alone may not replace a failed payment device.
  • Kitchen handoff: If a printer or display fails, can the kitchen receive clear tickets another way without creating an unmanageable bottleneck?
  • Power and connections: Would a spare help if the underlying problem were a network connection, cable, power outlet, or shared service rather than the device itself?

Count shared dependencies as well as individual units. Two printers are not independent backups if both rely on the same failed connection. Likewise, a second terminal already occupied with a separate queue may offer little practical spare capacity.

Rank failures by their effect on service: stopped work, a slower but manageable workaround, or a minor inconvenience. Also note how long the workaround can realistically last. A handwritten ticket might bridge a short printer outage, but staff should know how it will reach the kitchen and how the order will be recorded afterward.

Get a replacement timeline you can use

Ask each equipment supplier for a written replacement timeline, not just a warranty summary. Find out when support is available, how a fault is diagnosed, and when a replacement can be shipped or collected. A response time is not the same as the time until a working device is ready for service.

Build the timeline from the moment of failure: reaching support, confirming the fault, authorizing the replacement, shipping or pickup, and configuring the unit. Ask whether weekends and holidays change the process. If the supplier offers a loaner, ask when it arrives, what it costs, and whether it comes ready to use.

Then compare that timeline with your own operating hours. A restaurant closed for two days may have time to wait for a replacement; a seven-day operation with one counter station may not. Keep a separate plan for failures outside support hours, even if the device is covered.

Confirm the full quote for a spare or replacement. Ask about the device, setup, shipping, recurring licenses or subscriptions, accessories, and any charges for activating or switching equipment. A spare that needs an extra dock, cable, or account before it can work should be priced with those items included.

Finally, ask what happens to the failed unit. Can the restaurant keep a replacement on hand while the original is repaired? Must the failed device be returned first? Warranty rights and spare stock solve different problems; read the terms and ask a qualified adviser about contract questions when needed.

Compare spare configurations with a worksheet

The following figures are hypothetical and are not Fleksa prices. They compare one restaurant’s choices for a single critical kitchen printer over one year. The restaurant has no second compatible printer, and its supplier’s written estimate is two days to deliver and configure a replacement. The owner expects manual tickets to work for a short outage, but not comfortably through two full service days.

The estimated interruption cost is an operating estimate, not measured lost sales. It includes extra staff time and expected order-remake costs. The table includes the stated fixed purchase and setup costs, expected variable interruption costs, and the stated exception costs. It excludes payment processing, sales, taxes, financing, and any other costs not listed. The owner assumes one printer failure in the year; if none occurs, the interruption and exception costs shown for a failure would not occur.

OptionFixed costCosts if one failure occursEstimated first-year total
No spare; wait for replacement$0$300 interruption plus $30 delivery$330
Keep a compatible spare printer$220 purchase and $30 setup$40 interruption while switching$290
Use an existing second printer$50 setup and supplies$80 interruption plus $20 staff time to move it$150

Read the table as a decision under those assumptions, not a prediction. The existing second printer has the lowest estimated total: $50 + $80 + $20 = $150. It is the preferred choice only if the supplier confirms compatibility and the other station can give it up during the outage. If that condition fails, the dedicated spare is the cheaper of the two remaining choices at $290 versus $330.

Run the same comparison with your own quotes and service pattern. Check the result for no failures and for a longer-than-expected outage. The dedicated spare still costs $250 in a year with no failure, while the no-spare option has no listed cost in that case. A device may still be worth keeping when the interruption is unacceptable, even if the expected dollar saving is modest.

A spare terminal, printer, or interchangeable tablet serves a different purpose. Before buying or reusing one, request written confirmation for the exact device, operating system, printer connection, and payment processor involved. An old tablet is not automatically a replacement terminal, and a spare terminal is not automatically a replacement for every payment component. Ask what accessories and configuration are needed to perform the specific task.

For the broader purchase decision, the hardware buying guide covers questions beyond spare stock. For a spare, focus on the operational quote total and how quickly the unit can take over.

Practice the switch before service

A spare in a box is not a ready backup. Assign an owner for it, store it securely, and keep the required power supply, connection details, and setup instructions with it. Record who can access the necessary accounts and who to call if activation requires supplier help. Do not put passwords in an unsecured instruction sheet.

Arrange a simulated check with the provider using a spare test device and a nonproduction or clearly isolated test setup. Confirm in advance that the simulation cannot cause a real card payment, guest message, or courier dispatch. Do not use a real guest order as a test. If the provider cannot offer a safe way to simulate a step, document that gap and ask how to verify it without affecting guests.

  1. Start a timer when the person on duty is told the primary device is unavailable.
  2. Locate the spare, connect it, and follow the written setup steps.
  3. Use the agreed test setup to check the critical task, such as producing a test kitchen ticket without sending a guest communication.
  4. Record elapsed time, required permissions, missing accessories, and any supplier assistance needed.
  5. Return the setup to its normal state and update the instructions for the next shift.

Set a target based on your workable outage window. If the switch takes longer, decide whether to simplify setup, change the workaround, or accept the delay. Repeat the check when equipment, staff permissions, software, or network arrangements change.

A simulation checks the replacement procedure; it is not a live service pilot. If you later decide to use the spare during actual service, plan that separately with staff and the provider, with normal guest orders and payments handled through approved procedures. Do not assume a practice result guarantees an uninterrupted service.

Frequently asked questions

Does every restaurant need a spare POS terminal?

No. A second working station may provide enough capacity, or a short outage may be manageable. Keep a spare when the critical task has no adequate alternative and the replacement timeline exceeds your workable outage window.

Can an old tablet serve as a POS spare?

Possibly, but confirm the exact device and operating system with the provider. Also check the required printer connection, processor, accessories, and setup before relying on it during service.

Does a warranty eliminate the need for spare equipment?

Not necessarily. A warranty addresses repair or replacement under its terms; a spare addresses the time before a working device is available. Ask for the expected timeline and plan around your service needs.
