Ecomcy

Amazon, Walmart and TikTok Shop brand management

www.ecomcy.com

Ecomcy is a London-based agency that runs brands on Amazon, Walmart and TikTok Shop: account management, advertising including DSP, listings and creative. On Amazon it works across Seller Central and Vendor Central, and its founder, Vincenzo Toscano, wrote a guest post for the Clarisix blog.

What we do together

Vincenzo made the case in his guest post on our blog: a campaign can look successful in the ad console while putting pressure on the business, because ROAS does not account for the cost of goods, the fees and the returns behind every sale.

Ecomcy runs the account: campaigns, listings, creative and the day-to-day operation. Clarisix gives the brand and the agency the same view of what that work returns on Amazon: margin per product after every Amazon fee, refund, cost of goods and advertising line, and a Safe ACoS that shows how much ad cost each product can carry before it stops making money.

The monthly review then starts from the margin rather than the ad console. Clarisix covers Amazon Seller Central today, so Walmart, TikTok Shop and Vendor Central results stay in Ecomcy's own reporting.

Who it's for

  • Brands that want one agency across Amazon, Walmart and TikTok Shop
  • Sellers scaling Amazon advertising who need to know which products can carry more spend
  • Brands that want their own view of what the agency's spend returns, beyond the ad console

Scaling ad spend on Amazon?

Ecomcy runs the campaigns. Clarisix shows what each product earns once Amazon fees, returns, cost of goods and the advertising itself are in the number, so the budget goes to the products that can carry it.
