Marketplace seller agency, 16 people · Manchester (United Kingdom)
Client since July 2026
Task
For 19 client brands the agency ran seller accounts on eBay UK and Amazon.co.uk: listings, orders, returns and buyer messages in Seller Hub and Seller Central. Every store was opened from the same office IP in Manchester, and after one client's account received a policy warning the marketplaces treated the rest as related: 7 stores went under review, 3 were restricted for up to 12 days, and about one login in eight ended in a security prompt. Clients in Leeds and Liverpool lost sales over a bank holiday weekend, and account managers spent 14 hours a week on appeals.
Solution
Each store now has a static UK IP of its own from ProxyWing ISP proxies, registered to an internet provider and assigned to one customer only. Because the address stays the same between logins, eBay and Amazon see every client's store on a separate, stable British connection, so a warning on one client's account no longer spills over to the stores of unrelated businesses. The agency holds 38 IPs, one per store on each marketplace, pays per IP with unlimited traffic, and adds a new client without touching the others.
