Every outside dollar, under control.
42B turns your Outside Counsel Guidelines into a working rules engine, then reviews every line of every law firm invoice against it. Upload your invoices, get line-level flags with citations, and take the adjustments straight into your billing system. Setup takes about 10 minutes — no IT project, no data migration, no implementation partner.
No implementation. No procurement cycle. Send us your guidelines and we'll show you what your invoices are hiding.

42B reads your Outside Counsel Guidelines and writes the rules engine for you. Then you get the final say.
Upload your guidelines and 42B extracts every enforceable provision — rate caps, staffing limits, block billing prohibitions, non-billable administrative work, internal conference restrictions, travel policy, vendor and expense limits. You review what it extracted, edit anything it read differently than you would, and add rules of your own. Nothing gets enforced until you say it should.
- Reads the prose of your guidelines, not just task codes
- Every rule traceable to the section it came from
- Edit, disable, or add rules at any time — the engine is yours, not a template
