They help manage our AMS marketing with Amazon (Vendor Central) and consulting on the operation side. Tanya is managing our manual and auto campaigns, and Eric is providing guidance on the operation side. They were referred to us by our sister company, and I am learning through their webinars/newsletter and routine communications. They have a proprietary software to track campaign performance. If you are new to doing business with Amazon or lack of staff to manage your business, consider working with CPC and utilize their expertise.
