What is the true ROI of a €5,000+ custom website?
Is custom development an expense or an investment that pays for itself? An honest B2B ROI breakdown.

The math behind custom development
Many business owners initially hesitate between a €1,200 template and a €5,000 to €10,000 custom web application. But what is a mediocre website actually costing you per year in missed leads?
Scenario: 3,000 monthly visitors
Assume your website attracts 3,000 visitors per month with an average client value of €1,500:
- Template website (1% conversion): 30 inquiries per month.
- Custom website (3.5% conversion): 105 inquiries per month.
That's 75 extra inquiries per month. Even if you close only 10% of those incremental leads, that yields 7.5 extra clients per month (€11,250 in new revenue every month).
The conclusion
In a healthy B2B market, a custom Next.js website typically pays for itself within 2 to 4 months. After that, every additional percentage point in conversion is pure profit.
