I just took a demo of WHMCS. Was thinking between clientexec and whmcs. From 50-50, its now 80-20 in favour of WHMCS
Just a couple of small suggestions in add domain pricing page. In any case it is much better than earlier. IMHO, these things will make it near perfect
#1 - auto-populate the prices
e.g. if I enter price for .com for a year select 5 yrs from a drop down it should automatically add prices for 2-5 years in respective fields. I may then edit them or directly save.
#2 - copy pricing to another TLD
e.g. I have added prices for .com. I want to enter prices for .net. It should just get done if I tell it to copy .com prices for .net.
