Hello Sergio,

Thank you for reaching out to us.

Licenses can be upgraded to higher tiers through our store, by clicking on the "Upgrade" button:

A new modal opens up where you can choose available upgrade plans:

What you should know about the upgrade:

The price that you will pay for the upgrade will be a pro-rated charge, meaning you won't be paying for the price difference between licenses, since we cannot refund the time spent on the license you currently have.

Example:

You bought a Basic Yearly license for Amelia, which costs $79 (roughly $0.22 per day). 

After 100 days, you want to upgrade to Pro Yearly, which costs $119 (roughly $0.33 per day). 

Time remaining on Basic (what going to reduce the upgrade price): $58.3 (265 * 0.16) Time spent on Basic: $22 (100 * 0.22) Time remaining on Pro: $87.45 (265 * 0.33) So, the price is not Pro - Basic (119-79=40), but instead a pro-rated charge, and you are going to be charged around $87.45 - $58.3 = $29.15.

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.

Have a nice day!
