The short answer
A custom booking and loyalty app typically costs between €8,000 and €25,000 to build, depending on scope — a clean booking flow sits at the lower end, a full app with loyalty points, live content and multi-location support sits at the higher end. That is a one-time build cost, not a recurring per-transaction fee.
This applies to any business whose customers book something: clinics and dental practices, salons and studios, gyms, driving schools, tour and activity operators, restaurants, coworking spaces, entertainment venues. The mechanics are the same whether you are booking a treatment room, a class, or a table.
We built exactly this for B’moovd, a sports bar in Wolfsburg, Germany. It now holds a 5.0-star rating on the App Store.
Why this question matters more than it used to
Most businesses run bookings through a third-party platform — the kind that takes a cut of every reservation and puts its own name in front of the customer instead of yours. For years that was the only realistic option at small and mid scale.
It isn’t anymore. AI-augmented development has closed most of the cost gap between “custom app” and “generic SaaS tool” for a business of this size. Work that justified a €60,000 quote three years ago now lands in a range a serious SMB can actually approve.
What a third-party platform actually costs over time
Third-party booking tools typically charge a percentage per transaction — commonly 3–10% — plus a monthly subscription, indefinitely. For a business doing meaningful weekly volume, that passes the cost of a one-time custom build within 18–24 months, and it never stops.
The bigger cost is structural. You never own the customer relationship: the booking record, the loyalty data, and the app icon on your customer’s phone all belong to the platform. You do the work of earning the repeat visit; the platform keeps the evidence of it.
What we built for B’moovd, specifically
B’moovd is a sports bar in Wolfsburg, part of the Röhrdanz Unternehmensgruppe. Before the app, customers booked through a generic third-party tool with no branding and no data ownership. We built:
- Native iOS and Android booking, replacing the third-party tool entirely
- A B’Points loyalty system the business fully controls
- Live Bundesliga score integration — the reason customers open the app between visits
- Event discovery and exclusive member perks
The result: full product ownership, a 5.0-star App Store rating, and a direct data relationship with every customer who books.
That last point is the transferable one. Whatever your industry, the feature that keeps an app open between purchases is specific to your business — live scores for a sports bar, results for a clinic, class schedules for a studio. Generic platforms cannot build it, because it is not generic.
What determines the price within that €8,000–€25,000 range
- Booking only, single location — lower end. A clean reservation flow with real-time availability.
- Booking + loyalty — mid-range. Adds a points and rewards engine you actually own.
- Booking + loyalty + live content + multi-location — upper end. This is the B’moovd scope.
- iOS and Android together, versus one platform first — building both up front costs more than validating on one, but avoids a second build later.
The honest caveat
If you are doing very low booking volume, or still testing whether digital booking is worth it at all, a third-party tool is the right starting point. The math only favours ownership once volume and repeat-customer value justify it. Most established businesses with a regular customer base cross that line sooner than they expect — but not all, and it is worth checking rather than assuming.
If you’re weighing this decision
The question worth answering before committing either way: what did your booking platform’s fees add up to over the last 12 months, and would that money have been better spent owning the equivalent outright?
Run that number first. If it is small, keep renting. If it is not, the conversation is worth having.
