Reviews outside counsel invoices against billing guidelines, flags non-compliant entries by category, and produces the documents needed to approve, reduce, reject, and communicate those decisions. Covers the full invoice compliance workflow: line-item review through to formal firm escalation. Works with or without an e-billing platform. Where an e-billing system is in place, LEDES format and UTBMS coding are hard gates. Where there is no e-billing system, invoice submission by email is the channel and UTBMS coding is a best-efforts flag.
