There are different ways to approach the antonyms for "more inhouse," depending on the meaning and context of the phrase. In terms of inhouse, which implies something that is done within an organization or company rather than outsourced or externally hired, some antonyms could be outsourced, contracted out, or subcontracted. These words suggest that the activity or service is provided by a third-party entity, rather than being part of the internal operations of the organization. Alternatively, if we focus on the word "more," some antonyms could be less, fewer, or reduced, indicating a decrease in the amount or frequency of inhouse activities or processes.
