While you're on this thread... some quick feedback.
I'm a fan of your registrar service. I started experimenting with it not long ago and have begun moving most of my domains over. I understand it's still early days there. Any chance you could build up & clean up the billing reporting and controls for domains (separating it out better, making it easier to view just domain billing information & renewal info)? It's a bit haphazard currently. It would also be very nice to be able to register domains further out than a year (right now it's just a basic one year autorenewal on/off) - even if that offering cost extra per year to push the duration out. I'd guess the issue on wholesaling and allowing longer renewals, is that if the price goes up on you in the meantime, you can't pass that along (no buffer / profit margin built-in); so throw a reasonable fee on top for pushing the renewal out. As it is, I've been adding years on my existing registrar, before I move domains over to Cloudflare. Why do I want the longer duration? Peace of mind, instead of renewing every year. Not having to worry about domains expiring is a mental positive.
