Can I upgrade from professional to developer? Do I just pay the price difference?

Hi there.

I'll pass this question to our billing specialist Ricardo, and I'm sure he'll reply as soon it's possible.

Hi Joseph,

I noticed you paid $149 for your professional license. Developer package price is $499 and to upgrade it you should send us the difference ($350.-) to our paypal account (sales at ijoomla dot com).

After that you have send me the transaction Id and I will upgrade the license from here.

Let me know if you have more questions regarding this.

Best regards,
