Purchasing a licence

Hi. I’m very new to Wordpress. I want to create a website for a client using the Avada theme. Ideally, I want to purchase the theme, create the website on a temporary domain on my web hosting for him to approve and, once he is happy, create it on his domain using his web hosting.
Is this OK or would I have to buy it twice?

Assuming you won’t keep the theme installed on the temporary domain, you should be fine with one license.

Great - thanks for getting back to me
