Question on Licensing.

Hello,

I am planning to buy your product and have a question regarding the license. I know there are lots of discussions about License but I am little confused and I don't want to make a mistake before I make the purchase.

Hope you understand. Here are the questions.

1. I will be using your Fancy Product designer for selling customized products like T-shirts, Mugs, Caps etc. Which License do I need? 

2. I will have atleast 10 customizing products (T-shirts, Mugs, Caps, Key chains etc) that I will sell in the website. Is one license sufficient for all the products? 

3. I am going to start developing my website on Wordpress. I see your plugin is available only till Wordpress 4.9X. But my website runs on Wordpress  5.0.2. Does your plugin support latest wordpress version?

4. I will start development on a test domain and move the code to the actual domain later on once the development/testing is completed. Can I transfer the license to the Live website later on?

Regards,

Surendra
