Tradelines are the individual credit accounts that appear on a credit report. Each tradeline represents one relationship between you and a creditor: a credit card, an auto loan, a mortgage, a business line of credit, etc.
What lenders look at
- Number of tradelines: 5-10 active accounts is typical; very few or very many can be flags
- Mix of types: revolving (credit cards) plus installment (auto, mortgage, etc.) shows credit-management breadth
- Age: older tradelines show stability; “thin file” applicants have short or few tradelines
- Payment history: on-time payments boost score; late payments hurt
- Utilization: revolving balance / credit limit; under 30% is generally good
Business vs personal tradelines
Personal tradelines are on your personal credit (Experian, Equifax, TransUnion). Business tradelines are on your business credit (Dun & Bradstreet, Experian Business, Equifax Business). Many small businesses have very limited business tradelines because they pay vendors on personal cards or via ACH (which does not report).
Building business tradelines
Open business credit cards, get net-30 vendor accounts that report to D&B, finance equipment (the loan reports to business credit), and pay everything on time. Building business credit takes 2-5 years.
Thin file
An applicant with fewer than 3-5 tradelines is “thin file” and harder to underwrite. Lenders may compensate with alternate-data underwriting (bank statements, revenue) or require a personal guarantee.
