There is one very practical reason: maintenance.
Free templates can be useful for small projects, but paid templates often offer advantages that matter over time:
- regular updates
- better documentation
- faster compatibility fixes
- support from the developer
- more polish in design and features
When your website is important for your business, saving money at the start can become expensive later if the template is abandoned or breaks after updates.
The real question is not only whether the template looks good today, but whether it will stay usable and supported over time.
