License regular vs. extended

Hello, I’ve a question about the License. I read the difference between the Regular and the Extended License but I can’t understand one point.

If I would to buy for example a CV Template and I wanna adapt it for a customer and after I sell it to him, i need a extended License or can i purchase a regular license?

best regards

As long as you only do it for one client then regular is fine

and if i buy one template but i use it for adapting and selling to more customers?

No - one license/purchase = one website/client/CV etc.

Basically, you need to rebuy the item each time
