Hi,

You can do it so when OpenERP 8 stable version is released. But new release of website builder and e-commerce are just like a newly-born babies. They have to mature with a lot of features to compete with other dedicated softwares out there in the market.

I suggest two things for you.

1) You can just install the OpenERP 8 nightly build(developer version) locally and find out if they fit all your requirements. If you can develop or if you have your team of openerp developers, you can ask them to develop the features that are missing to meet your requirements. You can contribute the code to the OpenERP community. you will be appreciated for that.

or

2) You can integrate with other dedicated softwares that can be integrated with OpenERP through the webservices. You can find more info about the webservices in the OpenERP doc section.

You know, A few sample integration are the OpenERP-magento, OpenERP-PresaShop, OpenERP-any CMS like Wordpress or Portals like Liferay

You have so many solutions to meet your requirements

Thanks
