E-Billing Audit Engine

A full e-billing audit workflow for legal invoices. It compares time entries, rates, expenses, budgets, engagement terms, client and outside counsel guidelines, prior invoices, matter activity, staffing rules, UTBMS codes, adjustments, and matter status when those records are supplied. It makes only corrections directly supported by an explicit rule and documentary evidence, preserves all originals, and produces a confidence-scored audit trail for lawyer review.
