How can I transform a pdf catalog in an interactive online/offline shopping cart?

With https://www.publitas.com you can easily turn your PDFs into shoppable online catalogs. You can also integrate your online store in the catalogs through an iframe and add a shopping cart. Feel free to http://demostore.publitas.com/ to see what I mean.

There are a number of platforms that allow straight transfer of PDFs to online static pages, however, at Ceros, we strongly believe that the content should be maximized for the medium, therefore incorporating as much interactivity and animation as possible. It’s all in the cloud, so you can do it by either starting with a PDF or building from scratch. Check out http://www.ceros.com to see and hear our customer stories.

http://www.zmags.com/ is another good option. "With Zmags, you can easily create digital catalogs, interactive magazines and other online publications that are redefining the online browsing shopping experience across web, tablet, mobile, and social channels."

There are a number of catalog tablet applications for the iPad that can convert a PDF to an interactive shopping tool.  The one I would recommend would be Coffee Table. They have a technology process that lets shopper checkout in seconds.  It's very innovative.  They do all the processing for you.  They just need a PDF and a product data feed (e.g. GAN/CJ,Linkshare).  They can do it in days.  http://www.coffeetable.com/retailers
