I've been using Codisto to synch my shopify inventory with Amazon. We don't use FBA and fulfill using suppliers that dropship. We sell Apparel and Home Goods. The apparel products have tons of variants due to size/color combinations. We have @300 products and almost 7,500 variants, so creating them manually in Amazon is not an options and synching both ways is needed (product information, inventory, pricing...)
Codisto was working fairly well until Amazon changed their requirements for apparel to include more details on sizing including new standards. Codisto has not been able to synch my apparel products for at least 2 months and they have stated they will inform me when development is done on there end to handle Amazon's new requirements. Meanwhile, my apparel products are not listed on Amazon.
Does anyone know of a better app for synching products in general and apparel products in particular between Shopify and Amazon?
