What a Tradeline Is

A tradeline is one credit account on a report: the record of who extended you credit, on what terms, and how you have paid. Business credit files are built tradeline by tradeline, mostly from vendor accounts.

Why it matters

Thinking in tradelines turns build business credit into a countable plan. Scores like PAYDEX are computed from tradelines, so the questions become concrete: how many, from whom, reporting where, paid when.

Key facts

• Vendor (trade) credit, business cards, loans, and leases can all create tradelines.
• A tradeline only exists on a report if the creditor reports it there.
• Business tradelines show terms (like net-30), recent balances, high credit, and payment behavior.
• Age matters: older tradelines deepen the file the same way they do in personal credit.
• D&B's PAYDEX needs multiple reported trade experiences before a score can exist at all.

In practice

1. Inventory your current tradelines: which vendors and cards exist, and which bureaus each reports to.
2. Aim to add tradelines that report to D&B first, since PAYDEX needs reported data.
3. Keep every tradeline paid early or on time; one late tradeline on a thin business file weighs heavily.
