Amazon
Someone accountable for the account, every day
Conversion, keyword rank, Buy Box share, stock position, feedback and subscriptions — watched daily, reported monthly, and acted on the day something moves.
Most account management is a monthly report about things that went wrong three weeks earlier. Ours is a person and a detection system looking at the same account every morning, so a Buy Box loss is a Tuesday problem rather than a month-end finding.
We hold Seller Central and Vendor Central, handle account health and case work, chase listing reinstatements, and own the relationship with Amazon when something needs escalating. You get one team that can answer for the whole account rather than three vendors who can each answer for a part of it.
