Mobile app for restaurants and HoReCa — features, cost, integrations

A mobile app for a restaurant is no longer a gadget but a sales channel that works without intermediary commissions and builds a relationship with the guest. The question is no longer "is it worth it" but "where to start so as not to burn the budget". In this article we break down the features of a hospitality app, show a realistic split into an MVP and later stages, and answer the question of how much a food ordering app costs head on.

Why a restaurant needs its own mobile app

Marketplace platforms (delivery aggregators) charge commissions of 25–35% per order. At a scale of a few hundred orders a month, your own channel starts to pay for itself — even if it initially handles only part of the traffic. On top of that, an app gives you what an aggregator never will: data about your guests, direct contact (push), your own loyalty programme and control over your brand.

For the HoReCa segment (restaurants, cafés, chains, hotels) the key benefits are:

• Commission-free orders — delivery, pickup, order to the table.
• Table reservations integrated with the floor plan calendar.
• A loyalty programme that genuinely increases visit frequency.
• Data and marketing — segmentation, push notifications, location-based and time-limited promotions.
• POS integration — no double entry of orders into the kitchen system.

A hospitality app — the full feature list

Before we split the scope into stages, it helps to see the full map of what can be built. Not everything is needed straight away — but it is worth designing the architecture so that it can all be added later.

Food ordering

• A menu with categories, photos, variants and add-ons (e.g. size, sauce, ingredients).
• A cart with item editing and a summary.
• Fulfilment modes: delivery, pickup, order to the table (QR code on the table).
• Time slots and opening hours (blocking orders outside working hours).
• Discount codes, minimum order value, delivery zones and fees.

Reservations

• Choice of date, time and party size.
• Managing availability of tables and rooms.
• Confirmations and reminders (push / email / SMS), handling cancellations.

Loyalty programme

• Points for orders, rewards, coupons, "stamps" (every 10th coffee free).
• Membership tiers and personalised offers.
• A loyalty card in the app (code / QR to scan on site).

Account and communication

• Registration and login (email, phone, social login, Apple/Google).
• Order history and one-tap reordering.
• Push notifications about order status and promotions.

What an MVP must have, and what to add later

The most common mistake is trying to build "everything at once". An MVP (Minimum Viable Product) should reach guests as quickly as possible and start generating orders, so that decisions about further features rest on real data.

MVP scope (stage 1)

That scope lets you launch real mobile sales and gather data. We deliberately postpone reservations, an extended loyalty programme and multi-venue support — those come once we have confirmed the channel works.

Stage 2 — after validation

• Loyalty programme (points, rewards, coupons).
• Table reservations.
• A second or third fulfilment mode (e.g. adding order-to-table via QR).
• Segmented push campaigns and time-limited promotions.
• Full POS integration instead of the simple panel.

Stage 3 — scale and chains

• Support for multiple venues / a franchise network from one backend.
• Advanced analytics and recommendations based on purchase data.
• Integrations with inventory systems, accounting and external suppliers.
• AI capabilities: menu personalisation, demand forecasting, a support chatbot.

Integrations: POS and payments

This is where hospitality projects most often get complicated — and where decisions are best made in advance.

POS integration

The POS (point of sale) system is the heart of operations: it takes orders, prints kitchen tickets, settles waiters' tabs. A mobile app should deliver the order straight into the POS, with no manual re-entry. The options:

• A ready POS API (as offered by popular hospitality systems) — the fastest route, if the vendor provides an integration.
• Middleware / an intermediate layer — when several venues or different systems have to be brought under one standard.
• A simple panel to start — in an MVP a lightweight order-intake panel is enough instead of a full integration, with the POS integration added in stage 2.

Before quoting we always verify which POS is in use and whether it has an open API — that is one of the main factors driving cost and schedule.

Payments

In Poland the standard is BLIK, alongside cards and wallets (Apple Pay, Google Pay). The integration is delivered through a payment gateway (e.g. local payment operators) that handles authorisation, refunds and settlement. For an MVP, one gateway plus payment on collection is enough; wallets and instalment payments can be added later.

The cost of a food ordering app

The most important rule: the cost of a food ordering app depends above all on scope and integrations, not on "the app as such". The ranges below are indicative orders of magnitude for a project delivered with an experienced software house (native or cross-platform: Flutter / React Native).

The final quote is influenced particularly by:

• Number of platforms — iOS and Android alone, or also a web panel for the restaurant.
• Technology — cross-platform (one codebase for iOS and Android) usually lowers the cost compared with two native apps.
• Integrations — POS, payments, delivery systems, loyalty; every open integration takes time.
• Design — an off-the-shelf design system versus a bespoke, polished UX.
• Maintenance — hosting, support, updates for new iOS/Android versions (typically 15–20% of project value per year).

On top of that come fixed costs independent of your vendor: developer accounts (Apple USD 99/year, Google USD 25 one-off), the payment gateway (transaction commissions) and the server/backend.

How to approach the project so that it pays off

1. Start with an MVP and real data. Launch a narrow scope in one venue, measure conversion, acquisition cost and order frequency.
2. Design for integrations from day one. Even if the POS comes later, the architecture has to assume it.
3. Go cross-platform if budget is critical. One codebase for iOS and Android means a faster start and cheaper maintenance.
4. Do not buy features "just in case". Roll out a loyalty programme or reservations when the data shows they are needed.

Summary

A well-planned mobile app for a restaurant pays for itself through saved commissions, guest data and loyalty. The key is getting the staging right: a concise MVP (menu, cart, payments, one fulfilment mode), followed by reservations, a loyalty programme and POS integration in subsequent steps. That plan keeps the cost of a food ordering app under control and lets you grow the product on real results rather than assumptions.
