The development of an app, for example, starts at around €5,000 for an MVP (Minimum Viable Product). For a complete app with many features, the price can quickly reach €20,000 or more.
SaaS products have similar prices to apps. MVPs cost at least €5,000. Depending on the complexity and features, the price can quickly reach €20,000 or more.
Simple websites start at around €1,000. If you only need a website to present your services or products, you shouldn't expect to pay more than €5,000. We offer various types of software development. We specialise in app development, SaaS development and web development or web design.
