How Much Does a Web App Cost? Price Bands from Website to Company System

The short answer: we build a simple web application from CZK 1,990 per month, a mid-range one with login and admin from CZK 4,900 per month, and a complex company system from CZK 9,900 per month. For a one-time agency price, expect CZK 200,000 to 1,500,000 depending on scope. The subscription includes development, hosting, operations and support.
Now the longer answer — because "web application" means something different to everyone. And that's exactly what drives the price.
Website vs. web application: why the price differs
A website informs: it presents your company, services and contacts. Visitors read, maybe submit a form. A web application works: users log in, create and edit data, have different roles and permissions; the system calculates, monitors and reports.
Technically that's a fundamental difference. A website is a shop window — a web application is a machine with a database, a backend, user management and logic that has to be designed, programmed and tested. That's why you can get a website from CZK 1,990 per month, while a complex application can cost ten times as much.
Web application price bands
| Band | What it includes | Monthly subscription | Agency one-time | Delivery |
|---|---|---|---|---|
| Simple | presentation + forms, simple logic, no login | from CZK 1,990 | CZK 50,000 – 200,000 | 2–6 weeks |
| Mid-range | login, roles, admin, database, e-mails | from CZK 4,900 | CZK 200,000 – 600,000 | 1–3 months |
| Complex | workflows, integrations (ERP, accounting), reporting, multiple roles | from CZK 9,900 | CZK 600,000 – 1,500,000 | 3–6 months |
| Large system | dozens of screens, multiple system integrations, high load | individual | CZK 1,500,000+ | 6+ months |
Agency prices follow the usual hourly rates of CZK 1,200 – 2,000 and realistic effort. Our monthly subscription covers the same — just spread over time and with operations included. We described exactly how the model works in our article on app development as a subscription.
What makes up the price
For a mid-range web application, the effort splits roughly like this:
- Analysis and design (10–15%) — understanding processes, data structure, wireframes. Underestimated analysis is the most expensive mistake: it gets fixed in code.
- UI design (10–15%) — screens, components, responsiveness.
- Backend and database (30–35%) — data model, API, permissions, performance.
- Frontend (25–30%) — screens, forms, validation, interactions.
- Testing and deployment (10–15%) — tests, bug fixing, production environment.
After launch comes operations: hosting, monitoring, backups, dependency updates, security patches. With a one-time price this is a separate item (typically 10–20% of the build price per year) — with a subscription it's included.
What pushes the price up
- Roles and permissions — the finer-grained (branches, teams, approvals), the more logic and testing.
- Integrations — every connection to accounting, ERP, inventory or a payment gateway is extra work. It's also usually the main source of savings: manual copying between systems ends. We described a typical example on our internal company applications page.
- Reporting — dashboards, exports, charts over large data volumes.
- Data migration — moving from spreadsheets or a legacy system, cleaning and validation.
- High load and availability — hundreds of concurrent users, SLAs, scaling.
What brings the price down
- A clear brief — written processes and priorities shorten the analysis. Our guide on writing a technical specification helps.
- The MVP approach — launch the core that solves 80% of the problem and iterate on real usage.
- Standard technology — a proven stack without experiments. We describe our approach in choosing technology for a web app.
Subscription or one-time?
We offer both — your cash flow and plans decide:
- A subscription makes sense when you don't want to tie up hundreds of thousands upfront, you expect ongoing development, and you want operations and support covered by a single payment.
- A one-time price makes sense when you have a dedicated budget (e.g. a grant or investment) and the application won't change substantially after delivery.
Either way: the code and the data are yours. Detailed terms are in our price list, and our web development services on the websites and web apps page.
How to get a price for your project
- Configurator — an indicative price in 2 minutes.
- Consultation — 60 minutes with a developer and a PM: solution proposal, estimate and tier recommendation. If you order, the workshop is retroactively free.
And if you're also considering a mobile version, compare prices in how much does a mobile app cost — a responsive web app first and a mobile app in phase two is often the cheapest route.
