As private credit has grown into a multi-trillion-dollar asset class, corporate and commercial direct lenders face an increasingly consequential operational decision: how to service the loans they originate. The core choice is between outsourcing servicing to a third-party loan agent — an experienced intermediary who handles loan administration mechanics — or bringing servicing in-house using self-built tooling or purchased purpose-built software. This paper examines all three options in depth, with particular attention to the capabilities of modern SaaS servicing platforms such as LoanStreet, and offers a framework for determining the path that best suits their strategy, complexity, and growth stage.
