I'm setting up a repair business, where customers will mail in the item to be repaired. Everything will need to be done through the web. I'd like to use Magento to take payment, print postage, and track incoming and outgoing shipments. I also need CRM and project management/helpdesk functionality. Is there a plugin for Magento that can do these things? If not, are there any CRM's that integrate particularly well with Magento? Any other advice?
Thanks!
