„It will only cost you €2,500,“ says the web agency. Six months later, the bill is now €8,000 and the site still doesn't work properly. Sound familiar? You're not the only one - 84% of businesses exceeded their initial website budget by at least 50%.

The problem is not the agencies„ bad intentions, but the complexity of web development and the lack of transparency in pricing. Many “standard" features turn out to be additional costs, and ongoing costs are often mentioned briefly or omitted altogether.

In this detailed guide, we'll uncover all the hidden costs you may face, analyse real-life examples and show you how to properly plan your budget for 2025.
