Trade Line (Trade Experience)

A trade line (or trade experience) is one supplier's report of how a business pays it: typically the highest credit extended, the current balance, terms sold on, and the payment pattern expressed as percentages current versus 30/60/90+ days slow. Bureaus aggregate trade lines across reporting suppliers to compute payment scores — PAYDEX, DBT, payment indices — so the trade section of a report is the primary evidence, and the scores are summaries of it.

Read trade lines with attention to depth and recency. Ten experiences totaling $1.2M with a $300K high credit is a robust file; three experiences totaling $9K tells you almost nothing, and the resulting scores inherit that fragility. Recency matters because payment behavior turns quickly — experiences reported in the last three to six months carry the signal, while older lines describe a company that may no longer exist in that form. Also note the terms: paying net-10 suppliers in 30 days is materially worse than paying net-30 suppliers in 30 days, and dollar-weighted scores capture this imperfectly.

Contributing your own AR data to bureaus is worth considering. Reporting suppliers get cleaner data ecosystems and, at some bureaus, better pricing or reciprocal access; the industry works because suppliers contribute. Some credit managers hesitate to report good customers (fearing competitors will spot them) — a real trade-off, though the customers most worth protecting can usually be excluded from contribution files.
