I'm in the process of developing a kit to integrate some of the most popular web hosting industry software packages in to our outsourced services. I have already integrated a couple of the most popular software kits on the market, however I'd love to know which other software you use as a web host for:
Customer Support/Ticket Management
Web Hosting Billing/Payments
Website Administration Panels (WHM for example).
Payment Methods (PayPal Pay Flow Pro for example).
I'd love to hear everyones preference!
PS: It seems alot of the major players have developed API's for their systems, if only this was common practise for all systems!
