Register the entity, obtain an EIN, standardize your legal name, address, phone, and website across bank, SOS, utility, insurance, and vendor records. Inconsistency is the top cause of reporting mismatches.
Request your D-U-N-S with complete, consistent details, then validate ownership in your D&B account. Reconcile duplicates early. Add key lines of business and contact roles so reporters map data to the right file.
Use vendors and services known to furnish to D&B. Keep terms net and amounts commercially meaningful. Pay on or before due dates. Store invoices, PODs, statements, and confirmations for audit trails and disputes.
| Step | Why it matters | Evidence to retain |
|---|---|---|
| Form entity & get EIN | Enables a unique, lender-recognizable identity | SOS filing, IRS EIN letter |
| Standardize NAP+W | Prevents file splits and reporting rejects | Bank welcome letter, utility bill, website imprint |
| Request D-U-N-S | Opens your D&B file for trade mapping | D&B confirmation email, account screenshot |
| Verify ownership | Stops misattribution and fraud flags | Photo ID, formation docs, bank statement |
| Add lines of business & contacts | Improves reporter match rates | Account profile export |
They scan identity consistency, number and type of trades, timeliness (PAYDEX), volume trend, file age, any derogatories, and whether bank data corroborates revenue. The closer your documents match the trades reported, the faster risk teams clear conditions.
| Signal | What D&B needs | What underwriters look for |
|---|---|---|
| On-time vendor payments | Furnisher-transmitted line items with terms and dates | Pattern of early/on-time pays across multiple months |
| Commercial substance | Invoice amounts reflecting real operations | Material spend relative to industry and revenue |
| Documentation trail | Invoices, PODs, bank confirmations | Exact matches between invoice, payment date, and bank outflow |
| File age & mix | Multiple active trades over time | Diversity of vendors and aging beyond 6–12 months |
| Clean corrections | Timely disputes with evidence | Accuracy trend improving, no recurring mismatches |
PAYDEX is a timeliness signal, not a full capacity or fraud screen. Pair strong PAYDEX with visible, recurring activity, aging, and revenue proof for real approvals.
| Item | D&B view | Lender interpretation | Next move |
|---|---|---|---|
| PAYDEX 80 | On-time payments | Baseline timeliness; needs volume and aging | Add recurring trades and higher-ticket invoices |
| PAYDEX >80 | Early payments | Positive discipline; still verify substance | Maintain early pays while increasing scale |
| Thin file | Limited data | Immature risk picture | Target 3+ trades reporting for 3–6 months |
| Derogatory marks | Late/collections | Heightened risk | Resolve, document, and request updates |
Here is the lender-view interpretation to keep in mind:
