What Is a Business Reference Letter?

These letters are often required alongside resumes. For example, candidates applying for specialized roles may combine references with documents like a software engineer intern cover letter or a FP&A cover letter example.

Types of Business Reference Letters

Type Description Best Use Case
Employment Reference Written by a previous employer Job applications
Professional Reference Written by colleagues or clients Freelance or consulting roles
