SimpleSync » Sync by SKU

SimpleSync is very useful if you're selling different products that are physically the same. SimpleSync keeps the inventory of these items in sync. SimpleSync also helps you sell more when you're selling a unisex product. You're going to sell more items if you focus your product pages on men and women separately. Make two products in the Shopify admin, give them the same SKU and you're done! SimpleSync does the rest automatically.
