Discrepancy Desk

An invoice discrepancy tracker designed around the work of investigating a problem, following up with the right people, and documenting its resolution.

Review text-based PDF invoices, track disputed amounts and follow-ups, and archive resolved cases with their history intact. Upload the previous day’s Discrepancy Report to resume Active and Archived cases, then export an updated Excel report with aging summaries, charts, and pivot tables. Includes duplicate warnings and independent sign-in.
