Alex & Rob,
Are you looking to automatically sync your inventory levels for products you sell both through Amazon & Shopify? If so, check out Stitch Labs, we offer real-time sync between the two channels (and many others).
For example, if you make a sale on Shopify, the inventory level is automatically updated in Stitch and that change is also automatically reflected in Amazon. You'll also be able to compare sales across the two channels to help you make smart decisions to grow your sales by understanding how the two are similar -- and different.
We currently support Amazon.com, Amazon.ca, and Amazon.co.uk.
For sure, I think Bridge is on point with StitchLabs
Retail Tower is good for pushing ads to other platforms, this will bring traffic back to your store. Plus it is free, so that is a great way to drum up some interest in your products.
SitchLabs is strong in terms of syncornization. If you have multiple chanels and need to keep track of stock you will find this essential. Not only that, there is a great analytics component built-in which can be incredibly helpful for dealing with lots of inventory.
Hi there Kevin, oh dear!
Sorry to hear about RetailTower at this time, I'm sure they're working on a resolution ASAP.
Right now I think this app (paid, $9 a month right now) will do the trick for Amazon and a few others: http://apps.shopify.com/lexity-shopping-feeds
You can also look into Aten Software to generate Amazon Product Ads feeds for Shopify stores. Support for Amazon's "Selling on Amazon" program is also available for an added charge. You may need another app if you also need inventory synchronization from Amazon to Shopify and vice-versa.
