In this case why you recommend this Billing systems if is so hard to update?
For the same reason that virtually every other control panel on the planet -- CPanel, Plesk, DirectAdmin, etc. -- work in this manner: because it provides the best possible experience to the clients. And that's more important than whether or not it's easy for us to release module updates.
All your files are encrypted
I fail to see how that's relevant to billing integration.
Why Centova don't do own billing system, as i recommend in past
We get this request ALL THE TIME, likely because "that other" stream control panel supports this so people think it makes sense. IMO, it does not.
Trying to generalize your product to "do everything" forces you to stretch your development resources to the point where you can't make it "the best" at any one thing. We prefer to focus on developing (what we hope to be) the best streaming control panel available, and let the billing system developers focus on developing the best billing solution they can. Combine them and you get two polished, feature-rich products rather than one half-assed one.
this was basic request from begin, to allow me to add product without template fields, based on slots, bitrate, transfer, quite, with or without autodj
Without a valid account template, Centova Cast would have no idea what server type you want, what autoDJ type you want, etc. etc. We can't just hardcode those as options in the billing module because the server/autoDJ software will be different on each server depending on what the admin has installed. That's just one example but I trust that you'll understand the point I'm trying to make.
Anyway, what I was trying to explain earlier is that you can just create a single account template called "generic" or "standard" or something like that, and then use that template for ALL of your packages. Then you don't have to worry about creating a new template for each package, and that's just as good as being able to leave it blank.
PS: As i see IHost looks allot similar with Centova on icons
The silk iconset is free (
http://www.famfamfam.com), and yes, iHost uses it too. So does WHMCS, Sourceforge.net, and probably tens of thousands of other web sites and software products.
