Yes custom scripts
I agree if you go to a hosting company that has their own scripts (or ones that aren’t used all the time like MB and WHMAP)
They will defiantly look better because you know they are real business and are worth your money to pay for them.
Like people go fins some different scripts other then MB Perl Bill and WHMAP
There must be 100's of billing scripts and you guys use 3 why not go explore for as far as you guys know there could be a script for FREE :O that might be better looking and better built then MB or WHMAP.
