Choosing a Restaurant POS: Questions to Ask Before You Sign

The short answer: the right restaurant POS fits how your restaurant serves guests — counter, table, bar, or online — and lets you choose your own payment processor. The most expensive mistake we see is a POS that locks you into its own processing at a rate you can’t negotiate. Ask about processing before you fall in love with the features.

From Main Street in Huntington Beach to Koreatown in Garden Grove, we help Orange County restaurants choose and set up POS systems. Here’s what to ask.

What Kind of Service Do You Run?

• Quick service and counter: fast checkout, kiosks or online ordering, kitchen display screens, and tap-to-pay.
• Full service: table maps, coursing, check splitting, pay-at-the-table, and reliable tip adjustment.
• Bars and breweries: pre-authorized tabs, fast reorders, and age-verification prompts.
• Multi-location or catering: central menu management, deposits, invoicing, and combined reporting.

Does the POS Lock You Into Its Processing?

This is the most important question. Some systems only work with their own payment processing. That can be fine if the rate is fair — but you can’t shop it, and leaving means replacing your whole system. Ask:

• Can I use an outside processor? Which ones?
• If processing is bundled, what’s the effective rate on a typical month, including all fees?
• Is the hardware discounted in exchange for a processing commitment? What happens if I cancel early?

How Does It Handle Tips?

Tip handling affects your processing cost as well as your staff. When the final amount after tip falls outside the range a card network expects, the transaction can drop into a higher-cost interchange category. A good POS and processor setup keeps tipped transactions in their best category. Ask how the system adjusts tips, whether it supports tip-on-terminal or pay-at-table, and how it reports tips for payroll.

What About Online Ordering and Delivery?

• Does online ordering feed directly into the POS and kitchen, or is it a separate tablet?
• Are online orders priced separately from your dining room? Card-not-present transactions cost more, and they shouldn’t drag up your in-person rate.
• Can you show the same prices online, on delivery apps, and in-store? California’s Honest Pricing Law requires listed prices to include mandatory fees.

What Else Should You Check?

• Offline mode for internet outages, with sensible limits.
• Hardware ownership — buy versus lease, and what a lease really costs over its term.
• Support hours that cover Friday and Saturday nights.
• Reporting your bookkeeper can use for reconciling deposits and tips.
• Contract length and early termination fees for both the software and the processing.

Frequently Asked Questions

Should I choose a POS with built-in payment processing?

It can work if the effective rate is fair and you’re comfortable not being able to shop it. Many restaurants prefer a POS that works with outside processors, so they can negotiate rates over time.

Can I keep my POS and change processors?

Often, yes, if your POS supports outside processors. If it’s locked to its own processing, changing processors means changing POS systems.

Do tips affect my processing fees?

They can. If tip adjustments aren’t handled within network rules, some transactions may land in higher-cost categories. The right setup avoids that.

Should I buy or lease POS hardware?

Buying usually costs less over time. Leases can run for years with no early exit, so compare the total cost before you sign.
