Of course, we keep track of who has bought what in your shops. But we also keep track of whether they've bought something before.
You can also go the other way and click on a specific product and see who has bought that particular product. Maybe you need to send out an email to customers to let them know that there are new accessories in the shop or other information. Of course, you can send the email directly from Shoporama.
Of course, you can also export all your customers if you need to use them in another system (send them a catalog, a Christmas card or something).
