Does anyone use any out-of-box software for billing? I find it pretty difficult to bill Colo space with our current software. I am curious what is out there. Nothing great comes up from google searches.
There is a lot out there, but from what I've seen most will just use what works well with the Merchant accounts they are attached with so that everything is integrated. Fantastico offers a couple that you may wish to check out.
It's really tough to make billing softwares compatible with all those payment processors out there. First of all they all act different. Second, they keep changing over time.
Rightly pointed out molly, the changes over time make most of these softwares redundant, or they ask for upgrades, there are various available in the market.
I use Freshbooks. It is very simple but at the same time general so you can used it for colocation, dedicated servers or even shared hosting. We use it for colocation.
