How Self-Ordering Kiosks Lift Average Order Value 15–30%

Ask any operator who has run a lunch rush shorthanded and they'll tell you the same thing: the upsell is the first casualty. When the line is ten deep, "Want to make that a combo?" quietly disappears. Self-ordering kiosks fix that gap mechanically — and the result shows up in the numbers. Across the industry, kiosks typically lift average order value by 15–30%, and the reasons are consistent enough that you can plan for them.

This guide breaks down why that lift happens, where the extra dollars actually come from, and what separates a kiosk that grows your check size from one that just moves the line.

Why kiosks reliably raise average order value

A kiosk isn't a better salesperson than your best cashier. It's a more consistent one. It never gets tired, never gets rushed, and never decides to skip the add-on because the line is long. Every order gets the same upsell, the same modifier prompts, and the same combo suggestion — no exceptions.

That consistency compounds. On a busy day, a human team might attach a drink to only a fraction of orders; a well-built kiosk flow prompts on every order and lets the guest decline. Even a modest bump in attach rate, applied to every ticket, moves the average.

The pattern holds across very different formats. In INFI's own deployments, self-ordering kiosks at PJ's Coffee lifted average order value 45%, Juice Press saw roughly 15% more per order, and Oak View Group venues doubled basket size. Different menus, different guests, same underlying mechanics.

The psychology: why guests spend more at a screen

Higher checks aren't the kiosk squeezing people. They come from removing friction that suppresses spending at a manual counter:

• No social pressure. Nobody judges the guest who wants extra bacon, a second cookie, or the large size. Guests tend to customize and add more when no one is watching and no line is waiting behind them.
• The menu does the selling. High-quality photos, clear descriptions, and visible modifiers turn a plain order into a build. People add what they can see.
• No time pressure. At the counter, guests order fast to keep the line moving. At a screen, they browse — and browsing surfaces items they'd never have asked about out loud.
• Perfectly timed prompts. The "add a side?" question lands at the right moment, every time, framed as a suggestion the guest can tap past.

None of this is manipulation. It's the same reason people spend more ordering from a well-designed delivery app than when they call in a phone order.

Where the extra dollars actually come from

"Average order value went up" is vague. When you decompose a kiosk lift, it almost always traces back to four specific levers:

• Attach rate. Adding a drink, side, or dessert. The kiosk prompts on every order, not just the slow ones.
• Trade-up. The guest picks the large, the premium protein, or the loaded version — sizes and upgrades shown side by side with the price difference.
• Modifiers. Extra shot, add avocado, double meat — every modifier is one tap, with no awkward back-and-forth.
• Combos and bundles. Singles become meals, because the bundle logic is built into the flow instead of the cashier's memory.

The biggest wins usually come from attach rate and trade-up, because those apply to the widest share of orders. Modifiers add up fastest for build-your-own concepts like bowls, coffee, and boba.

What separates a kiosk that lifts AOV from one that doesn't

Dropping a screen in the corner doesn't guarantee a bigger check. The lift lives in the details:

• Menu photography. Items with appetizing images get added more often than text-only lines. If your kiosk menu looks like a spreadsheet, it will sell like one.
• Prompt placement. Suggest the drink after the entrée, not before. Suggest dessert at checkout, when the guest is already committed.
• Restraint. Two well-chosen prompts beat six. Guests tune out a kiosk that nags, and abandon carts when the flow feels long.
• Loyalty at the screen. Tying the kiosk to your rewards program turns a one-time upsell into a return visit. When a guest sees they're a few points from a free item, the next add-on sells itself.

That last point is where check size connects to repeat frequency. A kiosk that feeds your loyalty program doesn't just grow today's ticket — it raises the odds the guest comes back and does it again.

Kiosks don't replace your team — they redeploy it

The best operators don't buy kiosks to cut staff. They buy them to move labor off the register and onto the things that actually differentiate the brand: expediting orders faster, running food, keeping the dining room clean, and handling the guests who genuinely want a human. The kiosk absorbs the transactional volume; your people handle the hospitality.

That's also why the AOV lift sticks. The register never gets overwhelmed, so the upsell never gets dropped — even at peak.

How INFI thinks about kiosks

INFI is the Restaurant Growth Platform: your POS runs the register, INFI runs your growth. Kiosks layer on top of the POS you already use — Square, Toast, Clover, Lightspeed, or HungerRush — so you're not ripping out your system to capture the lift. The kiosk shares the same menu, modifiers, and loyalty logic as your online ordering, digital menu boards, and mobile app, so the upsell experience is consistent everywhere a guest orders.

Because it's one connected platform rather than a bolt-on device, the data flows both ways: what sells at the kiosk informs your menu, your marketing, and your bundles. Founded by Lucas Liu, Ph.D., a former restaurant operator, and backed by a $12M Series A, INFI now supports more than 1,800 restaurants with the same mission — reduce labor strain, elevate the guest experience, and preserve what makes each brand unique.
