Drumtap reconciles the invoices hiding between your books and the GC portal

Why it surfaced

Drumtap focuses on a concrete failure point: invoices that remain open in a subcontractor’s books but never appear, or appear incorrectly, in the GC’s pay-app portal. Its Starter plan accepts manual CSV uploads, identifies six discrepancy types, and drafts the AP email for review—while explicitly noting that the contractor still sends it.

A trade-contractor receivables tool that compares QuickBooks and general-contractor portal exports, flags payment gaps, and prepares dispute and refile packets.
