How much does a booking system or reservation app cost?

An inquiry form collects a preferred date, contact details and service information. Staff then check availability and reply. That flow can be entirely sufficient when you sell a small number of distinct services, or when every request needs a conversation regardless. What matters is that the confirmation message after submitting never claims a slot is booked if it hasn't actually been confirmed yet.

A real booking system needs to know what's available and reserve the right capacity the moment it confirms. It needs to handle simultaneous requests, changes and cancellations. That's a difference in what the software is responsible for, not just adding a calendar widget to a page. So before estimating, I ask who gives the final confirmation today, and where the authoritative record actually lives — in software, a spreadsheet, or a schedule staff update by hand.

The booking package in the price list starts at €900. For the agreed scope, we plan an availability calendar, an admin panel and notifications. We also define pricing rules, languages and the confirmation method the project needs. An apartment reserves a stay, a salon reserves a service duration, a car reserves a rental period — each case needs different rules for what counts as 'taken'.

A small set of concrete examples brings the most clarity. What happens if a guest extends their stay, a staff member goes on leave, or a vehicle is stuck at the garage? Who enters a booking that came in by phone? The answers determine the real scope of the panel and its checks. If that data isn't available to the system, automatic confirmation can't reliably account for it — so we agree together on who's responsible for entering it, alongside the technical feature.

The starting price for a custom web application is €2,500, over 4–10 weeks. We consider it when a booking connects several user roles, sales channels, calculations and integrations — for example, ticket sales that need to reconcile a seat, a payment, a document and a boarding check. That kind of system carries more responsibility than simply accepting an appointment.

Payment or fiscal-receipt integration isn't one universal add-on with the same price for everyone. It requires reviewing the provider, a test environment, and error-handling procedures. We also define cancellations, refunds and repeated notifications for the same transaction. The application's starting price doesn't mean every combination of these features is included — the quote states exactly which flows I'm building and how we verify their behaviour before launch.

Complexity grows with rules that depend on each other: seasonal rates, different resources, staff permissions, and data from another system. Importing an old record can require reconciling formats and checking for duplicates. Multiple languages need prepared content and a review of every message a user receives. Timeline also depends on access to third-party services and how quickly you make decisions.

Budget stays under control with a clear first version. We can start with an inquiry and manual confirmation, or automate one complete flow before adding others. What matters is that the limitation is visible to both the user and staff. You get a fixed quote within 48h of a short call and clarifying the scope. Hosting, payment fees and message-sending costs are kept separate from development, since they depend on the providers you choose and actual usage.

Leto Halkidiki organises private accommodation by destination, place and property, and supports four languages. Its current flow is built around inquiries emailed to owners. It's a concrete example of a portal with structured content and administration, but I don't present it as automatic availability tracking or accommodation payments.

Srbija Tours / DriveSoft, by contrast, connects reservations, ticket sales, QR validation, fiscal receipts and an operations panel. The platform has processed 150,000+ tickets and reservations, with 100+ internal users. These figures describe an existing project, not the scope every new client gets for the starting price. The case studies help you show which parts you actually need, and what would be unnecessary for your business in a first phase.
