The simple answer is: Yes, you can offer activeCollab to your clients as long as the license is purchased directly from us (by your client or by you) and as long as your clients are aware that they are using activeCollab.
You are even free to charge your clients for some value added services (such as localization, installation, maintenance, customizations etc), but you cannot charge them for the software itself. Prices listed on our website are the same for everyone.
Re-selling or re-distributing activeCollab as a re-branded or hosted service is not allowed.
You are also free to remove the 'activeCollab Powered' graphic from the footer if you wish, but you will need to have a Branding Removal License to do so. This license is not a white label license and you can't use it to sell activeCollab as your product. You can find out more about Branding Removal License here.
To sum up, you can charge for additional services that you provide to your clients, but only after a license is purchased from our online store at www.activeCollab.com. You can't introduce activeCollab as your product, change its name and resell it, or create a hosted service where you will charge your customers for access. All of these matters will be treated as a copyright and trademark infringement, and as such will be dealt with legally.
