we build the way back.

Why Constellation Engineering

What most appeal services won't do.

01

We work inside your account, not just on the letter.

Most appeal services write the appeal and tell you how to submit it. Constellation Engineering is authorised through Amazon's Service Provider Network (SPN) and works inside your Seller Central account, so you don't have to.

02

We fix verification failures, not only policy appeals.

Many sellers aren't stuck on a policy appeal at all. They're stuck on a failed business or identity verification. Fixing that can run through EU government registers, UK Companies House, compliance and entity documents, and technical setup on the machine you verify from. Typical appeal services don't do this, especially overseas providers, which are most often US-based.

Suspensions, blocked listings
