The Localization Margin Curve: Why Multilingual Delivery Rewards Workflow Ownership

Localization is the rare agency service where the underlying platform does most of the labor, which means the margin lives entirely in the workflow wrapper: terminology governance, QA, and version control. Agencies that own that wrapper sell a repeatable global-ready retainer; agencies that resell a translation subscription compete on price against the client's own CMS plugin. The window to claim the wrapper is open now because AI translation quality has crossed the threshold where clients notice the difference between governed and ungoverned output.
