Self-Ordering Kiosks for Pizza Shops: Handling Custom Builds

A burger is easy to put on a self-ordering kiosk. A build-your-own pizza is not. The moment a guest can choose crust, size, sauce, cheese level, and a dozen toppings — some on the whole pie, some on just one half — you're no longer selling a product, you're selling a configuration. That's exactly where a pizza restaurant kiosk earns its keep, and also exactly where a badly modeled menu falls apart.

This guide is for operators evaluating kiosks who already know the pitch and want the harder answer: how do you get the custom-build experience right without confusing guests, mispricing pies, or sending the kitchen a ticket no one can read?

Why pizza is the hardest thing to put on a kiosk

Most fast-casual menus are shallow. You pick an item, maybe swap a side, and you're done. Pizza is deep. A single "build your own" node can branch into hundreds of valid combinations, and the guest expects to see every one of them priced correctly in real time.

The complexity comes from a few places at once:

• Size-dependent pricing. A topping on a personal pie and the same topping on an 18-inch cost different amounts.
• Placement. Half-and-half, "extra on the left," light sauce — these are position and quantity modifiers, not just yes/no toggles.
• Tiered add-ons. The first three toppings might be included; the fourth starts charging. Premium toppings (prosciutto, burrata) price differently than standard ones.
• Specialty vs. custom. Guests want to start from a named pie ("the Margherita") and then modify it, not always build from a blank canvas.

A counter employee absorbs all of this in their head. A kiosk has to make it visible, tappable, and unambiguous — which is harder to design but, done well, more accurate than a hurried counter hand during a Friday dinner rush.

Model the build as a modifier tree, not a list

The mistake is treating a pizza like a flat menu item with a pile of checkboxes. Model it as a tree instead, where each level constrains the next.

1. Start with the base. Size and crust come first because they drive every downstream price. Lock these before toppings appear.
2. Branch sauce and cheese. These are usually single-select with a "none / light / regular / extra" scale, not free-for-all checkboxes.
3. Open toppings with placement. Every topping needs three states — whole, left half, right half — plus an optional "extra" quantity. On a touchscreen, a simple half-pie graphic that the guest taps is worth more than any dropdown.
4. Apply the included-count rule. Show a running "3 of 3 toppings included" counter so the price jump on topping four never feels like a surprise.

The payoff of getting this structure right is that the guest sees the exact price update as they build. No "we'll ring it up at the counter," no argument when the total lands higher than expected. Transparency at the screen is what makes people comfortable adding one more topping — which is the whole point.

Custom builds are an upsell engine, not just a convenience

Kiosks reliably lift average order value, typically in the 15–30% range across the industry, and pizza's build complexity is a big reason why. Every configuration step is a natural, low-pressure place to suggest more: a premium crust, a second cheese, garlic knots that pair with the pie, a two-liter for the family order.

The screen never forgets to ask, never feels awkward about it, and never gets slammed and skips the prompt. That consistency compounds. The same pattern shows up across INFI's customer base: PJ's Coffee lifted average order value 45%, Juice Press grew 15% per order, and Oak View Group venues doubled basket size. And on a build-heavy category like pizza, self-ordering kiosks have more of these upsell moments to work with than almost anything else on the menu.

The goal isn't to nag the guest into a bigger bill. It's to make the natural next choice — bigger size, better crust, a drink — visible at the exact second the guest is already thinking about their meal.

The order isn't done when the guest pays

A pizza kiosk that produces a beautiful checkout and an unreadable kitchen ticket has solved the wrong half of the problem. Custom builds have to translate cleanly to the line.

That means the placement and quantity modifiers need to survive all the way to the kitchen display — "half pepperoni (R), extra cheese, light sauce" has to render as something the make-line can actually execute, in build order — not as a wall of comma-separated tags. Tie the kiosk to your kitchen and customer displays so the ticket the maker reads matches the pie the guest configured, and so the guest sees an accurate order-status screen while they wait.

Keep the build consistent across every channel

Here's the part most kiosk conversations miss: the guest who builds a custom pie at the kiosk today wants to reorder that exact pie from their phone tomorrow. If your kiosk menu and your online ordering menu are two different systems with two different modifier trees, that reorder breaks — and so does your loyalty program.

When the kiosk, the web, the app, and loyalty share one menu and one guest profile, a favorite build follows the customer everywhere. That's the difference between a kiosk as a standalone gadget and a kiosk as one screen in a connected ordering system.

A short rollout checklist

• Audit your menu math first. Kiosks expose every pricing inconsistency you've been fixing by hand at the register. Clean the rules before you go live.
• Photograph the builds. People add more when they can see it. Good topping and specialty-pie imagery does real upsell work.
• Cap the depth. Sensible defaults and a "start from a specialty pie" path keep a blank-canvas builder from overwhelming first-timers.
• Keep staff on the floor, not the screen. The kiosk should free your team to run food and fix problems, not create a new station to babysit.

Where INFI fits

INFI is the restaurant growth platform — your POS runs the register, INFI runs your growth. INFI layers self-ordering kiosks, online ordering, loyalty, and displays on top of the POS you already run (Square, Toast, Clover, Lightspeed, HungerRush) so one menu and one guest profile power every channel, custom builds included. Founded by Lucas Liu, Ph.D., a former restaurant operator, and backed by a $12M Series A, INFI now supports 1,800+ restaurants.
