Start here if you're new to business credit

Business credit works differently from personal credit — different bureaus, different scoring models, and no single number that follows you everywhere. Before opening your first Net-30 account or applying for a card, it's worth understanding what you're actually building and how the three major bureaus (Dun & Bradstreet, Experian Business, and Equifax Business) see your company. The guides below cover that foundation: what business credit is, how it differs from your personal file, how each bureau works, and the two things that quietly determine your score — utilization and monitoring.

Once the concepts here make sense, Build Business Credit walks through the actual step-by-step process of opening accounts and building a file from zero.
