Who we serve

Built for state and local procurement

Designed for agencies that manage complex vendor contracts and need enforceable, auditable oversight at scale.

State Agencies

From DOTs managing multi-year construction contracts to environmental agencies overseeing compliance programs. Centorum tracks every modification and verifies every invoice against current terms.

Central Procurement & Finance

Hundreds of active vendor contracts across multiple departments. Centorum enforces terms across the full portfolio, automatically and consistently, with audit-grade documentation.

Audit & Oversight Bodies

Pre-payment verification with full evidentiary support. Every decision is traceable to a source document, every override is logged, every action is auditable.

How it works

From contract to decision, automatically

By the time an officer opens their queue, every invoice has been analyzed, every discrepancy flagged, every citation ready.

Ingests

Reads the base contract, every amendment, rate schedule, and purchase order. Builds a canonical model of all active terms.

Cross-references

Maps every invoice line against authorized terms: rates, quantities, dates, scope, acceptance. Line by line, clause by clause.

Decides

Flags issues with evidence. Cites the exact clause, calculates the dollar impact, and explains its reasoning across 86 categories of discrepancy.

Acts

Generates vendor correspondence, hold notes, and escalation memos, pre-drafted with specific contract references, ready to review and send.

Evidence-based enforcement

Every finding, cited. Every action, drafted.

When Centorum flags a discrepancy, it cites the exact clause, calculates the dollar impact, and generates the correspondence to resolve it. Officers review and act. They don't reconstruct.
