What it does

Executes invoice compliance review from line-item flagging through to formal firm communication. Encodes the methodology for reviewing invoices against billing guidelines, categorising violations, producing defensible approval decisions, and escalating systemic non-compliance.

How it works

  • Reviews an invoice against provided billing guidelines, flags violations by category (e.g., Block billing, Prohibited fees, Rate violations, Staffing, Late submission).
  • Produces a Line-Item Review Report with a table of flagged entries, issue details, and recommended actions, followed by an Invoice Approval Note summarizing the recommended payment decision.
  • If needed, drafts a formal rejection letter to the outside counsel and an internal rejection record.
  • Builds an invoice review checklist calibrated to the organization’s guidelines.
  • Identifies recurring compliance patterns across multiple invoices and prepares a formal non-compliance notice for the firm.
  • Uses modes to route tasks: Mode 1 for line-item review, Mode 2 for rejection communication, Mode 3 for review process setup, Mode 4 for pattern analysis, Mode 5 for relationship review triggers.
  • Documents are produced as .docx files with header data including Company, Firm, Matter, Invoice number, and date.

When to use it

Triggers include commands such as: 'review this invoice', 'check this against our guidelines', 'flag the billing issues', 'write the rejection letter', 'build an invoice checklist', 'our review process', 'block billing', 'UTBMS', 'LEDES', 'billing non-compliance', 'recurring violations', 'the firm keeps doing this', 'escalate the billing issue'. These map to Mode 1, Mode 2, Mode 3, Mode 4, and Mode 5 respectively.

What it can touch

The skill references and uses external billing guidelines and e-billing system details to assess entries. It may rely on placeholders when data is incomplete and outputs documents (.docx) containing Company Name, Firm Name, Matter Name, and date in headers.

Caveats

Does not draft or create billing guidelines or engagement terms; does not design fee arrangements; does not generate original matter instructions. Uses placeholders if input data is incomplete and flags missing data after producing documents.

Where does this skill come from?

From lawve-ai/awesome-legal-skills, a repository with 618 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
