Update stock levels on a Shopify store from a supplier's stock status RSS feed. The supplier has feeds in both XML and CSV and it will probably be performed on a cronjob. If a product appears on Shopify but not in the feed, it should be removed from sale (but left on the site). If it is possible to 'watch' the feed for updates, that would be ideal but not essential.
Future plans would include the automatic addition of products, as well as automatically placing supplier orders.
