PreBuy Voice Comms Server Question

[Jhriad]

I'm looking to host voice comms for my outfit and I was given the recommendation to use NFO or one or two other hosts. I noticed on a few other hosts they allow switching between say, Teamspeak & Mumble without changing the billing (but with a change in slots). Since we're still not quite sure which we want to use would we be able to switch without issue if we wanted to in the near future?

You can adjust your server configuration at any time through the order page. Doing this will not change your payment date or result in any payment unless the new configuration costs more than the old.
