Localization Margin Ladder

Localization Margin Ladder ranks where an agency sits on the value chain: reselling a subscription, running the translation pipeline, or owning the terminology and QA layer that governs every language the client ships. Each rung up the ladder raises gross margin and switching cost, because the client's brand glossary, review rules, and release cadence become agency assets rather than vendor settings. The ladder matters because AI translation has collapsed the price of raw word conversion, so the only defensible retainer is one tied to governance the client cannot replicate in-house. A concrete example: Lokalise routes copy through custom AI profiles that enforce brand terminology and tone, which means an agency that authors those profiles owns the standard every future translation is judged against. Phrase adds quality scoring on top of workflow automation, giving agencies a measurable QA artifact to attach to monthly reporting. Without that layer, a client can swap vendors in a week and the retainer disappears with them.
