Restaurant App Development: Orders, Menu & Delivery System

A restaurant owner recently told me: "Third-party delivery platforms take 30% of every order. That is 4,000 EUR a month in commissions alone. I want my own app." Simple business math -- and he was absolutely right.

But not every restaurant needs its own app. For some, the investment pays for itself within six months. For others, a well-designed website with an order form achieves the same result at a third of the cost. This article will help you figure out which side you are on -- and if you do need an app, exactly what it should include.

Why Third-Party Delivery Platforms Are Not Enough

Do not get me wrong -- platforms like UberEats, DoorDash, Grubhub, and Deliveroo are excellent channels for acquiring new customers. But they have a fundamental problem: the customer belongs to them, not to you.

When someone orders through UberEats, they are not looking for your restaurant -- they are looking for food. Tomorrow they will order from your competitor. You do not have their contact information, you cannot send them promotions, and you cannot build loyalty. You are just one of hundreds of restaurants in a feed, competing on price and placement.

Then there is the commission -- 25-30% of every order. If your average order is 25 EUR, you are giving away 6-7.50 EUR per order. At 40 orders per day, that is 250-300 EUR daily. Over 7,000 EUR per month. Over a year, that is 84,000+ EUR in commissions -- enough to build multiple custom apps.

Features Your Restaurant App Actually Needs

I have seen restaurants that wanted "everything" -- AI-powered recommendations, AR menus, a social network for diners. The result? An app that cost 45,000 EUR, with 80% of features never used. Start with what genuinely drives value.

Essential Features (Your MVP)

Recommended Features (Phase 2)

• Loyalty program: "Collect 10 orders, get the 11th free" or a points system. Increases return rate by 25-35%.
• In-app payments: Stripe, Apple Pay, Google Pay. When customers do not need to find their wallet, they order more frequently.
• Review system: Internal ratings help improve quality. Most importantly, negative feedback stays in your app rather than appearing on Google Maps or Yelp.
• Delivery zone management: Set zones on a map, each with different delivery fees and estimated times. Calculated automatically for the customer.

Premium Features (When Business Is Thriving)

• Table reservations: Online booking with time selection. If this is your primary need, read our guide on booking systems for business.
• Personalized recommendations: "Last time you ordered the margherita -- today's special: truffle pizza!"
• Multi-location support: If you run a chain, one app for all locations with a shared loyalty program and centralized management.

Real Costs -- Actual Numbers

Here is what restaurant apps actually cost in the current market:

Option	Price	What Is Included	Best For
Website + order form	2,000 - 5,000 EUR	Menu, form, SMS notifications	Small restaurants, <20 orders/day
PWA (web app)	4,000 - 8,000 EUR	Menu, ordering, push, offline mode	Mid-size, 20-40 orders/day
Native app (MVP)	8,000 - 15,000 EUR	Menu, ordering, push, tracking	Active restaurants, 30-60 orders/day
Full system	15,000 - 25,000 EUR	+ loyalty, payments, delivery, admin	Chains, 50+ orders/day

Plus monthly maintenance: 200-600 EUR (servers, updates, content management). And do not forget -- a professional food photography session costs an additional 300-800 EUR, but that investment pays for itself in the first week through higher order values.

Real-World Success Stories

Asian fusion restaurant (city center). Previously relying exclusively on UberEats with ~1,200 orders/month and ~7,500 EUR in commissions. We built them an app with menu, ordering, and loyalty program in 3 months. Cost: 14,500 EUR. Within 6 months, 40% of customers migrated to the app. Monthly savings: 3,000 EUR. The app paid for itself in 5 months.

Pizza chain (2 locations). Needed a delivery system. We built a Flutter app with two interfaces -- customer-facing and courier-facing. Admin panel through the browser. Cost: 22,000 EUR, 4 months development. Result: average order value through the app was 23 EUR (vs 18 EUR via third-party platforms -- because in the app there are no competitors side by side). Annual app revenue: 180,000 EUR.

Coffee shop (30 seats). Small venue. We advised against building an app -- too large an investment for their volume. Instead, we built a PWA with a digital menu (QR code on each table) and a loyalty card. Cost: 4,200 EUR. Customers love it, reviews are great, and the owner is not sitting on a 15,000 EUR debt.

When Your Restaurant Does NOT Need an App

I will be direct -- not every restaurant should build a mobile app. Here is when it is not the best investment.

This is not a permanent "no." It is a "not yet." When your order volume grows, the time will come.

Digital Menu -- Start Here Even Without an App

If a full app is out of budget for now, start with a digital menu. After COVID, QR code menus became standard, yet I still see restaurants with laminated paper menus. They work, sure -- but you are leaving money on the table.

A digital menu with a QR code on each table:

• Costs 500-2,000 EUR to create
• Lets you update prices and dishes instantly
• Shows high-quality photos and descriptions
• Works on any smartphone through the browser
• Collects analytics on what customers view most

We built a digital menu for one restaurant with the ability to order directly from the table. In the first month, the average check size increased by 12% -- because when people see attractive food photos, they order more. That is a return on investment in days, not months.

Delivery Management -- Should You Build Your Own?

This is the most complex part. Running your own delivery system means:

• A courier management dashboard
• Real-time GPS tracking
• Delivery zone and pricing configuration
• Automated order assignment to couriers
• Customer-facing map tracking

All of this adds 5,000-10,000 EUR on top of the base app cost. Is it worth it? Only if you have at least 30-40 delivery orders per day and your own couriers.

If delivery volume is modest, use a hybrid model: your own app for taking orders, but partner with a local courier service for fulfillment. This reduces both investment and risk while you scale.

Loyalty Programs -- Simple but Powerful

In my experience, a loyalty program is the single highest-ROI feature you can add to a restaurant app. Here is why:

Restaurant customers who participate in a loyalty program return 2.3 times more frequently than those who do not. This is not a theoretical number -- it is the average across multiple restaurant projects we have delivered.

Model	How It Works	Best For
Stamp card	10 purchases = 1 free	Coffee shops, fast food
Points system	1 EUR = 1 point, 100 points = 5 EUR discount	Restaurants with 15+ EUR avg order
Tier system	Bronze/Silver/Gold -- more spending, better perks	Chains, premium restaurants

A basic digital stamp card costs just 1,500-3,000 EUR extra to add. But it can increase annual revenue by 15-25%. That is the best ROI I can offer any restaurant owner.

Push Notifications -- How Not to Annoy Your Customers

I see restaurants ruin push notifications all the time. Sending daily messages: "Come for lunch!", "Today's specials!", "Friday means pizza!" Result: customers disable notifications within a week.

My rule: no more than 2-3 notifications per week. And each one must deliver real value:

• "Your favorite dish is back on the menu" (personalized)
• "-20% on orders placed before 2 PM" (real discount, limited time)
• "New dish launch -- first 50 orders get a free dessert" (exclusivity)

One restaurant generates 22% of all app orders through push notifications alone. But they send only 2 per week -- each with a concrete offer. Quality over quantity, always.

Your Step-by-Step Action Plan

One final piece of advice: do not try to copy UberEats. You are not UberEats, and you do not need to be. Your advantage is that you are local. The customer who loves your food wants a direct relationship with you. The app is simply a tool to maintain that relationship.

Conclusion

A restaurant app is not about technology -- it is about building a direct relationship with your customers and keeping more of your revenue. For restaurants processing 30+ orders daily through third-party platforms, the math overwhelmingly favors building your own ordering channel.

Start small, start smart. An MVP with ordering, a digital menu, and push notifications is enough to prove the concept. Add delivery management and loyalty features once you have the data to justify them. The restaurants that succeed with apps are the ones that think of the app as a business tool, not a technology project.
