The Storage Margin Curve: Why Warehouse Architecture Now Sets Agency Gross Margin

Warehouse architecture has quietly become an agency margin decision, not an IT decision. When reporting latency, egress fees, and per-seat query costs sit inside a fixed retainer, every architectural choice either widens or erodes the spread between what a client pays and what delivery costs.
