POS system for restaurants: a guide for US owners

A POS system for a restaurant takes orders at the table or counter, sends them to the kitchen, keeps checks open by table and seat, records tips, and passes each total to a card terminal. In a US casual dining room, the features are the easy part to judge in a demo. The expensive part is the setup behind them: whether tips and service charges are recorded as different things, whether the tip reports match what the IRS and the Department of Labor expect, and whether sales tax lands on the right lines.

We don't rank POS brands. We provide terminals and processing, so we see how restaurant setups hold up at the end of a pay period. This guide sticks to US rules. If you run a restaurant in Canada, our guide to a restaurant POS in Canada covers Quebec's billing rules and the provincial tip rules, which work differently. Card costs, surcharges, and chargebacks are in our restaurant credit card processing guide. Rules cited here are as of October 2026.

What does a restaurant POS system need to do?

Run the floor, feed the kitchen, and keep a clean record of every dollar, including the dollars that belong to your staff. Take this table to every demo:

For the general parts of any POS, see our guide to what a POS system is. The rest of this guide is about what's specific to a restaurant.

How should orders flow from the table to the kitchen?

Every order should reach the right station once, readable at a glance, with modifiers in the kitchen's own language. That sounds obvious. It's also where most demos are too polite to show you a problem.

So run a real test. Ring up a table of six with two allergies, a split check, and a main course held for a late arrival. Then add a takeout order to the same queue and 86 an item halfway through. If the ticket is hard to read in a quiet demo room, it'll be worse at 7:30 on a Friday.

Reports are the other half of the kitchen question. Say a casual dining spot in Columbus sold 420 burgers last month at $16, with $4.80 of food cost each, and 140 salmon plates at $27, with $10.50 of food cost each. Per plate, the salmon earns more over food cost: $16.50 against $11.20. Across the month, though, the burgers brought in $4,704 over food cost (420 times $11.20) and the salmon $2,310 (140 times $16.50). Both numbers matter when you rework the menu, and a POS that tracks item cost gives you both without a spreadsheet.

How should a restaurant POS handle tips?

It should record every tip by employee and shift, tell card tips from declared cash tips, log any change to a tip after the check closes, and feed all of it to payroll. Several federal rules depend on that data.

Start with how tips get onto a card. Prompting for the tip on the terminal while the guest holds it is the cleanest route. When servers adjust tips after the card is authorized instead, Visa's guide for restaurants says the merchant can add up to 20% to the authorized amount without liability for authorization-related disputes, and recommends a new authorization above that (Visa). Your system should catch the over-20% case by itself.

The tip credit and why your tip report matters

The Department of Labor's Fact Sheet #15 lets an employer pay a tipped employee a cash wage of at least $2.13 an hour and count tips toward the rest of the federal minimum wage, currently $7.25. That tip credit can't be more than $5.12 an hour or more than the tips the employee actually received. If tips plus the cash wage don't reach the minimum wage, the employer makes up the difference.

Here's how that plays out. A server paid $2.13 an hour works 30 hours in a week. The minimum wage for those hours is $217.50 (30 times $7.25), and the cash wage is $63.90 (30 times $2.13). If the server's tips that week come to $120, the two add up to $183.90, so you owe another $33.60. Your POS tip report is how you'd spot that. The same fact sheet says some states require a higher cash wage or don't allow a tip credit at all, and where state law is more protective, it applies.

Tip pools, managers, and card fees

Tips belong to the employee. Fact Sheet #15 says an employer can't require employees to hand tips to the employer, a manager, or a supervisor, and that managers and supervisors can't receive tips from a traditional tip pool. If your POS calculates tip-outs, check that a manager's login can't be added to the pool by default.

On card fees, the same fact sheet allows an employer that pays a percentage to the card company to pass that percentage on when it pays out charged tips, as long as the employee's wage stays at or above the minimum and the tip is paid by the regular payday. Plenty of owners skip the deduction. If you take it, make sure the POS applies it to card tips only.

Employees have a reporting job too. The IRS says an employee who receives $20 or more in tips in a month must report them to the employer by the 10th of the following month. A POS that prints each server's card tips and asks for declared cash tips at clock-out makes that a two-minute task.

Are service charges tips?

No, and your POS has to know the difference. A tip is whatever the guest decides to leave. A service charge is an amount you add. Our guide to service charge vs tip goes deeper.

The Department of Labor says a compulsory service charge, such as 15% of the bill, is not a tip and is part of the employer's gross receipts (Fact Sheet #15). The IRS agrees from the tax side. Its tip recordkeeping page lists what makes a payment a tip: it's made free from compulsion, the customer can choose the amount, and the amount isn't negotiated or set by employer policy. Without those, it may be a service charge. Service charges you pay out to employees are wages, with income tax, Social Security, and Medicare withheld. Service charges you keep are your income.

That's why a common shortcut, setting up an automatic gratuity for large parties as a "tip," causes trouble in three places at once: payroll, tip credits, and sales tax.

How do service charges affect sales tax?

Sales tax is set by each state, so start with your state tax agency's rules for restaurants and test them on whole checks. California shows how much the service charge question matters.

California's tax agency, CDTFA, says in Publication 115 that a tip is generally optional when the customer adds it to the bill or leaves it separately, and an amount the retailer adds to the bill automatically is a mandatory charge subject to tax. Its examples include a notice that an 18% gratuity will be added to parties of 8 or more. Calling the charge a "suggested tip" or saying the guest can remove it doesn't change its mandatory nature. CDTFA also asks restaurants using a POS system to make sure tax is correctly applied to mandatory charges.

Here's what that looks like on a check. A party of 10 at a restaurant in San Diego runs up $640 in food and drink, and the POS adds an 18% service charge of $115.20. At an example tax rate of 9.5%, the tax on that charge alone is $10.94. A system that files the charge under tips won't collect that $10.94 from the guest, even though CDTFA treats the charge as taxable.

Records count too. Under CDTFA's Regulation 1603, since January 1, 2015, amounts are presumed optional and not taxable when a restaurant keeps records consistent with reporting them as tip wages for IRS purposes. Without those records, that presumption doesn't apply. If you run a restaurant anywhere in California, ask your accountant to check your service charge setup against both documents.

What tip reports does the IRS expect from a restaurant?

Beyond each employee's monthly report, a bigger restaurant may owe an annual return of its own. The IRS's instructions for Form 8027 say employers of large food or beverage establishments file that form each year to report food and beverage receipts and tips. The instructions define which establishments count. They also say tipping generally isn't considered customary in a cafeteria-style operation, or where at least 95% of sales other than carryout carried a service charge of 10% or more.

The form comes with an 8% rule. When the tips employees report for a period come to less than 8% of gross receipts (or a lower rate the IRS approves), the employer allocates the shortfall among directly tipped employees who reported less, and the allocated tips go in box 8 of their Forms W-2, with no tax withheld on them. The instructions treat service charges and automatic gratuities paid out to employees as wages, not tips, and leave the related sales out of the receipts figures.

Say a large dining room has $50,000 in gross receipts for a payroll period, and its directly tipped staff report $3,400 in tips. Eight percent of $50,000 is $4,000, so $600 has to be allocated, following the method in the instructions. That math only works if your POS keeps service charges separate from tips and tracks receipts and tips by employee. Quebec has an 8% rule as well, but it works per employee under Revenu Québec's rules, which our Canadian restaurant guide explains. Don't set up one country's rule in the other's restaurant.

There's one more reason to keep tips clean in 2026. The IRS's new deduction for qualified tips covers 2025 through 2028 (IRS), and starting in 2026, Forms W-2 report qualified tips separately in box 12 with code TP, with a Treasury Tipped Occupation Code in box 14b (IRS). Whoever prepares your W-2s can only work with the tip data your POS hands them.

What payment features should a restaurant POS have?

Terminals that get the total from the POS, go to the table, and take every card your guests carry. The checklist is short:

1. Integrated terminals, so nobody retypes a check total.
2. Portable terminals for pay at the table, with the tip prompt on the screen.
3. Chip, tap, Apple Pay, and Google Pay on every device.
4. Split payments by seat, item, or amount, each as its own card sale.
5. An offline mode with limits you set, or switched off. Our guide to store and forward covers the risk.
6. An automatic batch close every night.

Our POS terminals come in countertop, wireless, and portable models that read chip, tap, and swipe and take Visa, Mastercard, Interac, Apple Pay, and Google Pay. Our restaurants page covers pay-at-table setups, and our guide to what a POS system costs has current price ranges.

Questions to ask before you sign

Get written answers to these:

1. Can I use my own payment processor, or is processing bundled with the software?
2. What does processing cost per card type, in writing?
3. Can service charges carry their own tax and payroll settings, separate from tips?

Common restaurant POS mistakes

• Setting up an automatic gratuity as a tip.
• Letting a manager's login join the tip pool.
• Holding card tips until the processor pays you, instead of paying them by the regular payday.
• Taking a card-fee deduction from cash tips as well as card tips.
• Testing tax one item at a time instead of on a full check with a service charge.
• Signing for bundled processing without a price per card type.
• Assuming the vendor's default settings match your state's rules.
