How to Build a Restaurant Ordering App with AI

Last updated: August 2026.

DoorDash publishes commission rates of 15, 25, or 30 percent depending on plan, and that number, not the interface, is what actually decides whether a restaurant ordering app is worth building. Get the commission math or the POS integration wrong and the app either loses money or creates more kitchen chaos than it solves.

The commission math that decides this

Third-party delivery marketplaces charge real commissions, with no separate monthly fee. At low order volume, that commission is cheaper than building and maintaining your own ordering channel. The math flips at higher volume, roughly 250 to 400 monthly repeat delivery orders for a single location is where a direct ordering channel starts saving more than it costs to run. Below that line, marketplace commission is often the rational choice regardless of how appealing "owning your own channel" sounds.

POS integration is where builds succeed or fail

An ordering app that doesn't talk cleanly to your point-of-sale system creates more problems than it solves. Toast, Square, and Clover all offer partner APIs for menu sync, order injection directly into the kitchen, and real-time availability updates. Without that integration, someone is re-keying app orders into the POS by hand during the dinner rush, exactly when mistakes happen and tables wait longest. Menu sync matters just as much: when an item sells out or a price changes, it needs to update in the app immediately, not hours later after someone remembers to edit it manually.

Picking a POS is part of this decision, not separate from it

If you're already running one of these for payments, building your ordering app around that same system avoids a second, disconnected point of failure.

"Commission-free" doesn't mean cost-free

Toast markets its direct online ordering as commission-free, and it is, no per-order cut goes to a third party. You still pay for the POS package itself, payment processing, approved hardware, and implementation, so commission-free is a real saving compared to a 15-to-30-percent marketplace cut, not a free feature bolted onto your existing setup. Price the whole package before comparing it to marketplace commission, not just the headline "no commission" claim.

What this looks like to build

The practical path with a tool like Huxly starts with describing the restaurant in a paragraph, cuisine, locations, whether you handle delivery yourself, which POS you use, and what loyalty mechanic you want, and letting it scaffold the menu screens, cart, checkout, and admin panel as a real native app, in Expo, Flutter, or Swift, for a flat $25 or $99 a month rather than custom-development rates. Stripe (connected as one of Huxly's one-click backend options) typically handles payment processing, and push notifications carry order status (received, in the kitchen, ready, out for delivery) so customers aren't calling the front counter asking where their food is. The POS integration itself, wiring Toast, Square, or Clover's partner API into the menu sync and order flow, is still work that has to happen regardless of which tool builds the app around it. This is also worth knowing if you were planning around GloriaFood specifically, it's being retired, and anyone still on it will need an alternative regardless of which path they take next.
