What document typically needs to be signed before using self-service platforms?

The correct choice is the Master Services Agreement (MSA). An MSA is a foundational document that establishes the terms of engagement between a service provider and a client. It delineates the responsibilities, liabilities, and expectations of both parties, which is particularly important when using self-service platforms.

Signing an MSA ensures that all legal and operational stipulations are clarified before services are rendered, reducing the risk of misunderstandings or disputes later on. This agreement typically outlines issues such as service levels, payment terms, intellectual property rights, and confidentiality clauses.

In the context of self-service platforms, where clients often manage their advertising activities independently, having an MSA in place is crucial as it provides a clear understanding of the contractual relationship and protects both entities from potential complications that may arise from the use of the platform.
