The four sections of a Paydex report decoded, the four most common error patterns that drag the score down, and the 30-day iUpdate dispute workflow that moves them off the file.

The 1–100 Dun & Bradstreet Paydex demystified: the vendor reports D&B weights, the net-30 vs net-15 vs net-60 math, the milestone scores that unlock capital, and the 3–6 month climb from a brand-new EIN to a Paydex 80+.
