Restaurant POS Buying Guide: 7 Questions Before You Sign

A restaurant owner in Nashville called me. He'd signed a 3-year Toast contract 18 months earlier. Three terminals, Build plan, the works. His restaurant was doing $700K a year. His total POS cost over 3 years was going to be $62,000.

He was calling because he wanted to switch to Square. His buddy had Square and paid $720 a year in software fees. "Can I get out of my Toast contract?"

No. He couldn't. The early termination fee was $4,500. The hardware couldn't be reused. He was stuck. $62,000 for a POS system at a $700K restaurant. That's 3% of his revenue. For a POS.

A bad POS decision costs you $5,000-$15,000 to fix. You'll pay for hardware you can't reuse, spend weeks retraining staff, and lose sales during the transition. A good POS decision saves you 2-3% on processing fees, reduces labor cost by 1-2%, and gives you data that improves every other part of your business.

Here's the thing about POS salespeople: they're not lying to you. They're just not telling you the whole truth. The 7 questions below are the ones they hope you won't ask.

Industry Data & Sources:

Toast's S-1 filing reports the company serves over 106,000 restaurant locations.

Square's official pricing shows in-person processing at 2.6% + 10¢ per transaction.

The 3-Year Cost Is the Only Number That Matters

Don't compare monthly software fees. Compare total cost over 3 years including hardware, software, processing, and any add-ons. Monthly fees are designed to look small. "$69 a month? That's nothing." Multiply by 3 terminals, add processing, add hardware, and suddenly it's $56,000.

A 3-terminal full-service restaurant processing $500,000 per year in cards:

Toast (Build plan): Software: $4,644/year. Processing: $13,200/year. Hardware: $3,000 (one-time). Total 3-year: $56,532.

Square (Plus plan): Software: $720/year. Processing: $13,500/year. Hardware: $1,600 (one-time). Total 3-year: $44,260.

Clover (Dining plan, negotiated processing): Software: $3,238/year. Processing: $10,800/year. Hardware: $3,500 (one-time). Total 3-year: $45,614.

Toast costs $12,272 more than Square over 3 years. The question is whether Toast's better table management and reporting are worth $4,091 per year. For a full-service restaurant doing $1M+, probably yes. For a $500K restaurant, probably no.

I had a client in Austin who did this math and chose Square. Saved $12,000 over 3 years. His only regret? He didn't do the math before his first POS purchase. He'd been on Toast for 2 years before switching. That's $8,000 he'll never get back.

Ask every vendor for a 3-year total cost quote in writing. Include all hardware, software, processing, installation, training, and any add-on fees. Compare the quotes side by side. If a salesperson won't give you a written quote, walk away. I've had vendors refuse. "Our pricing is customized." No it's not. They just don't want you comparing.

Payment Processing: The Lock-In You Don't See Coming

Toast: No. You must use Toast processing. Square: No. You must use Square processing. Clover: Yes. You can use Clover's processing or a third-party processor. Lightspeed: Yes. You can use your own processor. SpotOn: Yes. You can use your own processor.

If you process more than $500,000 per year in cards, processor choice matters. A competitive interchange-plus rate of 0.25% + 5¢ above interchange works out to roughly 2.0-2.2% effective rate. Toast's 2.49% + 15¢ is 0.3-0.5% higher. On $500,000 in processing, that's $1,500-$2,500 per year.

If you process less than $250,000 per year, processor choice matters less. The difference between 2.3% and 2.6% on $250,000 is $750 per year. The convenience of an integrated processor might be worth $750.

But here's what nobody tells you about integrated processing: the rate you sign up at is not the rate you'll pay in year 3. Toast and Square both reserve the right to change your processing rate with 30 days notice. I've seen Toast raise rates by 0.1% on renewal. "Market adjustment." On $500K in processing, that's $500 a year. Not huge. But it's $500 you didn't budget for.

Clover with a third-party processor locks your rate by contract. If your processor tries to raise rates, you switch processors. You keep the same Clover hardware. That's the real value of processor choice. Not the lower rate today. The ability to keep the lower rate tomorrow.

Contracts: The $4,500 Paragraph Nobody Reads

Toast: 2-year contract typical. Early termination fee is the remaining months of your contract or a flat fee, typically $500-$1,000 per terminal. Square: Month-to-month. No early termination fee. Clover: Month-to-month through most resellers. Some resellers require a contract. Lightspeed: 1-year contract typical. SpotOn: Varies by reseller.

A 2-year contract isn't necessarily bad. Toast often offers free hardware ($3,000-$5,000 value) with a 2-year contract. If you're confident Toast is right for you, the free hardware is worth the commitment.

But if you're unsure, month-to-month is safer. You can switch after 6 months if the system isn't working. The flexibility is worth paying for hardware upfront.

The Nashville guy I mentioned earlier? His contract had an auto-renewal clause he didn't notice. His 2-year contract auto-renewed for another 2 years at month 20. He had a 60-day window to cancel the renewal. He missed it by 3 weeks. The salesperson had mentioned it during the demo. Once. In passing. While showing him the table management feature. He was looking at the floor plan, not listening to the contract terms. That's by design.

Read the contract. The whole thing. Especially the sections titled "Term and Termination" and "Fees." If you don't understand something, ask. If they can't explain it clearly, that's a red flag.

Offline Mode: The Friday Night Test

Every POS needs an offline mode. When your internet goes down during Friday dinner service, you need to keep taking orders and processing payments.

Toast: Offline mode processes all payment types. Orders sync when internet returns. Square: Offline mode processes swiped cards only. No chip or contactless offline. Clover: Offline mode processes all payment types. Orders sync when internet returns. Lightspeed: Offline mode processes all payment types. Limited reporting offline.

Square's offline limitation is a real problem. If your internet goes down and a customer only has a chip card or Apple Pay, you can't process the payment. You're writing down credit card numbers on paper and manually entering them later. I've done this. It's terrifying. You're holding a piece of paper with 47 credit card numbers on it. If you lose that paper, you lose thousands of dollars and have to call 47 customers to ask for their card numbers again.

Ask for a demo of offline mode. Watch what happens when they unplug the internet. Can you still take orders? Can you still process payments? Can you still print kitchen tickets? If the answer to any of these is no, keep looking.

I watched a Square demo where the salesperson "accidentally" couldn't get offline mode to work. "It usually works. Must be the wifi here." We were in their office. On their wifi. If it doesn't work in their office, it won't work in your restaurant.

Customer Support: Call Them Before You Buy

Ask these specific questions:

What are your support hours? Toast: 24/7. Square: Business hours with limited weekend support. Clover: Depends on reseller.

What's your average wait time? Toast: Under 10 minutes. Square: 15-30 minutes. Clover: Varies.

Do I get a dedicated account rep? Toast: Yes. Square: Only on Premium plan. Clover: Depends on reseller.

What's your uptime guarantee? Toast: 99.9%. Square: 99.9%. Clover: 99.9%.

Call their support line before you buy. See how long you wait. Ask a real question about your restaurant concept. Judge the quality of the answer. You'll be calling this number during service. Make sure someone competent answers.

I called Square support on a Saturday at 7pm to test this. 22-minute wait. The rep was friendly but couldn't answer my question about splitting checks across multiple payment types. She put me on hold twice to "check with the team." Total call time: 41 minutes. During a real dinner service, 41 minutes is an eternity. Your server is standing at the terminal with 4 customers waiting to pay. The kitchen is backed up because orders aren't coming through. 41 minutes.

Toast answered in 4 minutes. The rep solved my problem in 6 minutes. That's the difference between $0/month and $129/month per terminal. Whether it's worth it depends on how much you value your Friday nights.

Integrations: "We Integrate With QuickBooks" Means Nothing

Your POS needs to talk to your accounting software (QuickBooks, Xero), your payroll provider (Gusto, ADP), your inventory system (MarketMan, xtraCHEF), and your online ordering platforms (DoorDash, Uber Eats).

Toast: Integrates with most major platforms. 200+ integrations. Square: Integrates with most major platforms. 300+ integrations. Top-tier API. Clover: Integrates through the App Market. 500+ apps. Quality varies. Lightspeed: Integrates with most major platforms. 100+ integrations.

If you use a specific accounting or payroll system, verify the integration before you buy. "We integrate with QuickBooks" might mean a direct integration or it might mean you export a CSV and import it manually. Ask for a demo of the specific integration you need.

I had a client who bought Clover specifically because "it integrates with QuickBooks." It did. Sort of. The integration exported a CSV file once a day. He had to manually download it, reformat it, and upload it to QuickBooks. It took 45 minutes every Monday. He'd been doing this for 8 months before he mentioned it to me. "I thought that's what integration meant."

It's not. A real integration syncs automatically. You set it up once and it runs in the background. If you're exporting CSVs, you don't have an integration. You have a data export feature. There's a difference.

Hardware Lock-In: Can You Take It With You?

POS hardware is expensive. If you switch systems in 3 years, can you reuse any of it?

Toast: No. Toast hardware only works with Toast. Square: Partially. Square Reader and Square Terminal work with other systems. Square Register is proprietary. Clover: No. Clover hardware only works with Clover. Lightspeed: Yes. Lightspeed runs on iPads. You can reuse the iPads. You can save even more by buying refurbished iPads from Discount Electronics — same hardware, roughly half the price.

If you think you might switch systems, Square or Lightspeed are safer bets. Your hardware investment isn't locked to one vendor.

The Nashville guy's Toast hardware? $3,000 worth of terminals, routers, and printers. All of it became e-waste the day he wanted to switch. He couldn't even sell it. Toast hardware is tied to the merchant account. The buyer can't activate it on their account. It's a brick.

Square's Terminal and Reader work as standalone payment devices even without the Square POS. You can use them with other systems that accept Square payments. That's not full reusability, but it's better than a brick.

The Decision Matrix

Red Flags in a POS Demo

The salesperson can't show you offline mode working. Walk away.

The salesperson can't tell you the early termination fee. Walk away.

The salesperson says "we can build that feature" when you ask about something specific. It doesn't exist. Walk away.

The salesperson won't give you a written quote with all fees. Walk away.

The salesperson pressures you to sign today for a "limited time discount." The discount will be available next week. Walk away.

I've walked out of 3 POS demos. All three salespeople called me back within 48 hours. Two of them suddenly had "manager approval" for the discount they said would expire. One of them actually got angry. "You're making a mistake." If a salesperson gets angry when you won't sign immediately, imagine how they'll treat you when you have a problem.

Your POS is the nervous system of your restaurant. It touches every order, every payment, every tip, and every report. Spend more time choosing your POS than you spend choosing your oven. A bad oven costs you $200 in wasted labor per day. A bad POS costs you that plus 1-2% in processing fees, 1-2% in labor inefficiency, and data that lies to you about how your business is doing.

The Nashville guy? He's still on Toast. He'll finish his contract, switch to Clover, and save $6,000 a year. He's counting down the months. Don't be him. Do the math before you sign.
