Selling on Amazon is a lot more involved than you might think. Luckily, there are a lot of companies out there who can help you sell your products on Amazon. Of course, Modern Retail will ensure the products from your website are integrated with Amazon and Amazon orders flow back to your website and POS or ERP system, but eventually you may need more help. For example, you may need a firm to help you with product research so you know how to position and price your items on Amazon. Or, you might need a little extra help coming up with a strategy to get Amazon reviews and feedback.
Fortunately, the folks at BuyBox Experts and Bigcommerce have created the attached PDF document: The Amazon Sellers' Solution Provider Directory. This directory includes a number of companies you can call on to help you with your Amazon integration.
