The process is quite simple. First, you would need to inform us of the enhanced countries you plan to cater to. Then, you will have to wait for the solution provider to confirm. Once that is done, we will then agree at some future date to switch you to the upgraded plan (with a lower transaction fee). You will have to pay our referral fee difference and that pretty much is it. The same is applicable to upgrading from Starter to Enterprise or from Pro to Enterprise.
