There has been talk of asset management in Kayako v4 but nothing officially confirmed. We are using Kayako at the moment and a spreadsheet for asset management as I've yet to find a decent all-in-one product.
Kayako is a great Helpdesk though, nothing else even comes close to it IMO.
I hope Alex Polizzi visits that Hotel before November
Filth and grime are the order of the day, do not waste your money!!!!! - Norbreck Castle Hotel, Blackpool Traveller Reviews - TripAdvisor
Kayako eSupport integrates with AD, however it's not free. Nothing even comes close to Kayako IMO.
I think they might even do some special educational pricing.
Take a look at SmarterMail it is one of the best Windows mail servers around in my opinion, it also has migration tools to move away from Merak.
There is also a free edition available which might be suitable for you requirements.
There is no such thing as "unlimited" so why are you offering it? Would you walk into PC World and find an unlimited hard disk? So are you misleading customers in paying for something you cannot physically offer
As per the distance selling regulations you need to display a valid postal address and telephone number on your website.
You also appear to be using a cracked/cloned/un-licenced copy of Kayako SupportSuite.
Wishing you every success with your new venture.
