We are not a website agency. We build large systems

Prices from real projects

This development cost calculator is not guesswork — it is based on dozens of custom software projects we have delivered since 2003, from small intranets to large enterprise systems.

AI lowers the cost of development

AI tools now speed up the routine part of the work under the supervision of senior developers. The cost of building an application comes out lower than would have been possible a few years ago.

An estimate, not a commitment

The result is an indicative calculation, not an offer. We prepare a refined estimate after roughly two meetings about your requirements — with agile development you then steer scope and cost as you go.

Design your system, we will price it

An online software development cost calculator: eight quick questions, no contact form. The range recalculates with every answer.

E.g. warehouse, orders, invoicing and CRM = 4 areas. After scope, this is the single biggest factor.

The calculator gives you a range, not a price tag

Every project is different and a few questions cannot replace analysis — treat the result as a first orientation. We usually prepare a refined estimate after two initial meetings covering your processes and requirements. And honestly: on larger projects built agilely, the final price takes shape as the work goes on.

What most affects the cost of development

Scope and number of modules

The cost of an information system grows mainly with the number of modules, user roles and process complexity. A small intranet for one team is a different matter from an ERP running warehousing, production and finance.

Integrations and data migration

Connecting to payment gateways, banks, an existing ERP or legacy systems is among the most expensive items in a software cost calculation. The same goes for migrating data from an old system.

Mobile apps and security

The cost of a mobile app alongside the system, enterprise sign-in (SSO, Active Directory) or multi-company operation move a project into a higher bracket — the calculator accounts for that.

Frequent questions about development costs

It depends on scope. A smaller web application or an intranet for one team usually runs in the hundreds of thousands of CZK, while a large enterprise system with integrations and a mobile app runs into millions. The calculator above gives you a range based on eight questions — we set the exact price after an initial consultation.

For a system running company operations — warehouses, orders, production or invoicing — what matters most is the number of modules, roles and connections to your existing software. An employee intranet tends to be cheaper than an ERP because it does not have to handle complex processes or accounting integrations.

Mostly the scope and number of modules, the number of user roles and the sign-in method, integrations with other systems, migrating data from an old solution, and whether a mobile app is part of the system. How well prepared your brief is also plays a role.

The routine part of the work — repetitive code, tests, documentation — is now much faster with AI tools under the supervision of senior developers. We do not cut corners where senior judgement is needed, but overall effort drops, and that shows in the price.

It is an indicative estimate from a few key parameters, not a binding offer. It is meant to show whether a project sits in the hundreds of thousands or in the millions. We usually prepare a refined estimate after two meetings about your requirements.

No. The calculation runs entirely in your browser and nothing is sent anywhere. We do not ask for contact details — if you send yourself the estimate or get in touch, that happens only at your initiative.

Let us refine the estimate against your requirements

Send us the result and a few sentences about the project. In one or two no-obligation meetings we will go through the brief and prepare a refined estimate of scope, price and timeline.
