Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
So, I'm using OpenERP 7.0 under the AGPL license. From my understanding of AGPL, it should be possible for me to remove the openerp logo and footer. After all, it is just another source code modification.
Since I'm using OpenErp as a web service for my clients, would changing the branding be any problem ?
Short answer: Yes, you can remove the link and logo from the web frontend.
As pointed out by Yoni Rabkin, from FSF "Under section 7(b) of AGPLv3 the copyright holder/s of the software is permitted to require, as an additional restriction of the license, that you preserve and not remove a "powered by ..." logo."
By the time being, OpenERP uses the AGPL with no additional restrictions, and so you are not requiered to keep the link and logo.
Off course, you must offer your customers an effective way to get the full source code, and you must keep the appropiate copyright and warranty notices in it.
Thoughtfully reading the licence is quite tedious but it's higly recommended.
The commercial and social impact of removing the OpenERP brand from the web frontend is another issue I would recommend you to debate through the mailing lists or with the folks at OpenERP directly.
