"How much does an app cost?" is the first question almost every business owner asks, and the honest answer is that it depends on a handful of decisions you can actually control. Two quotes for "a booking app" can be far apart because the two developers imagined two very different products.
I am not going to give you a price list here. Any number without a scope is a guess. Instead, this is a breakdown of what makes an app more or less work to build, so you can read quotes critically and shape your scope to fit your budget.
1. The number of user roles
Every distinct type of user is close to a separate product. A simple catalogue app has one role: the customer. A booking app usually has at least two: the customer who books and the business that manages bookings. A field-service platform like NeonTask has dispatchers, admins, technicians and client companies, each with different screens and permissions.
Each role needs its own screens, its own rules about what it can see and change, and its own testing. If you can serve the first version with fewer roles, for example by letting your staff use a simple web admin instead of a separate staff app, the cost drops noticeably.
2. Backend logic, not screen count
People often estimate apps by counting screens. Screens matter, but the real work often hides behind them. Compare two "confirm booking" buttons:
- One saves a request and emails your team.
- The other checks real availability across several staff members, applies service durations and travel time, blocks the slot, handles a double booking race, sends a confirmation in the user's language and schedules a reminder.
Both look like one button. The second is many times more work. When you read a scope, look for the rules: availability, pricing, approvals, statuses, cancellations, refunds. That is where effort goes.
3. Integrations
Each connection to an outside service adds work, testing and a dependency you will need to maintain:
- Maps and location (showing places, directions, tracking).
- Payments. In Lebanon this is often its own conversation, because card payments are not always the default and many businesses rely on bank transfer, Whish or OMT. See accepting payments in apps and websites in Lebanon for the practical options.
- SMS, WhatsApp or push notifications.
- Email delivery.
- An existing system you already use: an ERP, accounting software, a spreadsheet you want synced.
An integration with a well-documented, modern API is straightforward. An integration with an old system that has no API can be a project of its own.
4. Languages and right-to-left support
An English-only app is simpler than a bilingual English and Arabic one. Arabic is not just translation. Layouts mirror, icons that point in a direction need flipping, fonts behave differently and text lengths change. Building bilingual from day one costs less than adding Arabic later, because retrofitting right-to-left support means revisiting every screen. I wrote about this in building bilingual Arabic and English apps.
5. Design depth
There is a wide range between "clean, consistent screens using a solid component set" and "custom illustrations, animations and a unique interaction for every screen". Both are valid. The first is often right for a first version, where your goal is to learn whether customers use the app. Custom motion and illustration can come later, once you know which screens matter.
6. Platforms
Building once with React Native for both iOS and Android, which is how I built Pro Clean+ and Local Meals, is usually more efficient than building two separate native apps. It is not free, though. Each platform still needs its own testing, store setup and occasional platform-specific code. If your users are overwhelmingly on one platform, starting there can be a reasonable way to save. I compare the options in React Native vs native.
7. Admin panel and reporting
Almost every business app needs an admin side. A basic one lets you view and edit records. A richer one has dashboards, filters, exports, role-based permissions and audit history. Reports in particular grow quickly: every "can we also see..." is a query, a screen and a test. Decide what reports you need on day one and what can wait.
8. Content and data you provide
If the app shows services, menus, products or vendors, someone must write and organize that content in each language, and supply photos. When this is late or incomplete, the project stalls and costs grow. When it is ready early, the build moves faster.
9. Quality bar and testing
How many devices will you test on? Do you need automated tests on critical logic? Will you run a pilot with real users? Higher quality bars cost more upfront and less later. For anything that touches money or bookings, I recommend investing here.
10. Hosting, infrastructure and operations
The app needs servers, a database, backups, monitoring and a way to deploy updates safely. My own setup is Dockerized services on Linux servers with a CI/CD pipeline. The initial setup is a one-time effort. Running it has an ongoing cost: server fees, plus someone keeping it patched and healthy.
11. What happens after launch
The quote for building an app is not the total cost of having one. Budget for:
- Fixes and adjustments in the first weeks after launch.
- Yearly OS updates from Apple and Google that require rebuilding and resubmitting.
- Library and security updates.
- New features once real users tell you what they need.
See app maintenance after launch for what that looks like in practice.
How to compare quotes fairly
When you have quotes from several developers or agencies, check:
- Is the scope written down? If a quote has no scope document, you cannot compare it.
- Does it include the backend and admin, or only the mobile app?
- Who owns the code, the store accounts and the server? It should be you.
- Is store publishing included? Setting up listings and passing review takes real time.
- What does support after launch look like, and for how long?
- How are changes priced? Scope always shifts a bit. Know how that is handled before it happens.
A low quote that leaves out the admin panel or publishing is not cheaper. It just moves the cost to later.
How to reduce cost without hurting the product
- Cut to one core flow for version one, and make it excellent.
- Use a web admin instead of a separate staff app where possible.
- Postpone in-app payments if bank transfer or cash on delivery works for your customers at first.
- Have content and decisions ready on time.
- Pick a developer who will tell you what not to build.
