Infrastructure for Contract & Billing Terms Extraction

Billing terms extraction requires a formally documented standard terms library — what the firm's standard T&M rate structure looks like, what constitutes a 'not-to-exceed' clause, and what billing provisions are unusual or risky. At L3, the standard terms library is current and findable, enabling the NLP system to compare extracted terms against baseline and flag deviations. Audit requirements ensure that billing policy documentation exists and is authoritative, giving the AI a reliable reference for risk-flagging non-standard terms.

Contract extraction requires signed contracts, amendments, and SOWs to be systematically deposited into an accessible repository through a structured intake process. At L3, legal or finance workflows mandate that every executed contract is uploaded to the contract management system with required metadata (client, engagement, execution date, contract type). This systematic capture ensures the NLP extraction system has access to the full contract portfolio, not just the subset someone remembered to upload.

Billing terms extraction outputs must conform to a consistent schema matching the billing system's configuration requirements — rate fields, cap fields, milestone trigger fields. At L3, the PSA billing configuration schema defines what structured fields extracted terms must populate: billing type (T&M/retainer/fixed fee), rate by role, expense allowance, invoice frequency, and not-to-exceed amounts. This consistent schema enables auto-population of billing system configuration from extracted terms.

Contract extraction requires API access to the contract repository (to retrieve signed PDFs and amendments), the standard terms library (for risk comparison), and the billing system (to write extracted configuration). At L3, this API-based flow enables the NLP system to retrieve contracts, extract terms, compare against standard library, and push configuration to the billing system programmatically — eliminating manual re-keying of contract terms that creates transcription errors.

The standard terms library and rate card reference data that the extraction system uses for risk comparison changes infrequently — annual rate card updates and periodic legal standard terms reviews. At L2, scheduled periodic maintenance of the reference library aligns with these natural update cycles. Contract extraction itself operates on static documents (signed contracts don't change), so the system doesn't require event-triggered updates for the extraction corpus — only for the comparison baseline.

Contract billing terms extraction primarily integrates the contract repository with the billing configuration system via a point-to-point connection. At L2, this direct integration enables extracted terms to flow into billing system setup fields without requiring an integration platform. The standard terms library integration is similarly direct — the NLP model queries a comparison dataset from a single source. Broader integration with CRM or project management is valuable but not required for core extraction functionality.
