online Customer Cad File Rendering and making changes by themselves and other things -- 2

mainly works with online cad files ,What I need is a software that I can’t afford to purchase, but I need something that works from email because a lot of our requests come from email either directly from a client or from a form or from some kind of trigger then from there I’d like it to go into my CRM then from the CRM going into the project managementand then deliver to the client Right now we have cats software for all the manufacturers that we sell products for we do the layout we do the rendering and we come up with a parcel list, but then we have to save it as an XML file and then we have to bring it in to some quoting software, and then from there once a customer agrees to the price into the terms then we have to go into QuickBooksand do a invoice and then turn the invoice into a purchase or do a proposal and then turn it into an invoice and then turn it into a purchase order so we have so many software to do one thing that can be kind of like jumping hurdles so it slows things down people want quick answers and want to login and upload a floor plan then pick some attributes and let the software do the rest. then they can make small adjustments. there are also the clients that want to take cad blocks and place it themselves more hands on
