Centorum reads every contract, every amendment, every rate schedule — then cross-references every invoice line against authorized terms. Discrepancies are flagged with evidence. Your team reviews, not reconstructs.

“A vendor bills Connecticut $21,000 for construction support. The contract has 10 amendments. Buried in Supplement 8, the hourly rate for a Senior Project Manager was lowered to $128. But the invoice bills $157 — the old rate. The difference is $696 on one line item, one invoice, one month. The reviewer has 200 other invoices this week. They miss it.”

How it works
By the time a procurement officer opens their queue, Centorum has already done the work. Every invoice has been analyzed. Every discrepancy has been flagged. Every citation is ready.
Reads the base contract, every amendment, rate schedules, purchase orders — 60+ pages across multiple documents. Builds a canonical understanding of all active terms.
Maps every invoice line against authorized terms. Checks rates, quantities, dates, scope, acceptance requirements — line by line, clause by clause.
Flags issues with evidence. Cites the exact clause. Calculates the dollar impact. Assigns a confidence level and explains its reasoning.
Generates vendor correspondence, hold notes, and escalation memos — pre-drafted with specific contract references, ready for the officer to review and send.
The decision view
When Centorum flags a discrepancy, it doesn't just say “hold.” It shows the exact clause, the exact rate, the exact dollar impact — and generates the correspondence to resolve it. The officer's job goes from “reconstruct the contract from scratch” to “review Centorum's work and act.”

Every finding cites the original document, page, and clause. Click to see it in the actual PDF — not a summary, the real thing.
Pre-drafted vendor requests, hold notes, and escalation memos — referencing specific contract terms and dollar amounts.
Centorum decides, but humans override. Every override requires a written reason and is logged in the audit trail.
Breadth
From arithmetic errors to sophisticated contract manipulation. Centorum detects every category of invoice issue — across every contract, every vendor, every billing period. Automatically.
Rate discrepancies
Traces rate changes across multiple contract amendments to identify which rate is current — and which invoice line uses a superseded one
Duplicate & phantom billing
Detects the same hours, items, or deliverables billed across multiple invoices — including split invoices designed to avoid review thresholds
Scope creep & unauthorized work
Identifies line items that don't map to any authorized billable item in the contract, including work added without an approved change order
Contract interpretation failures
Resolves which amendment supersedes which, applies document precedence clauses, and detects reliance on overridden terms
Timing manipulation
Catches end-of-fiscal-period billing games, front-loaded milestones, backdated invoices, and billing outside the authorized performance period
Vendor pattern abuse
Identifies systematic behaviors across invoices — repeated ceiling-billing, ambiguity exploitation, chronic documentation gaps, and cross-contract rate drift
Acceptance workflow manipulation
Detects retroactive acceptance, blanket acceptance misuse, self-certified deliverables, and billing before required sign-offs are on file
Payments without legal authority
Flags invoices against expired contracts, terminated agreements, or where no valid modification authorizes the billed work
Including structural contract violations, cost misclassification, deliverable manipulation, SLA misrepresentation, compliance red flags, and more.
Government agencies spend hundreds of billions annually through contracts. Post-award enforcement — making sure vendors deliver what they promised at the price they quoted — is done manually, from memory, against thousands of pages of legal documents. Most discrepancies are never caught. We're replacing that with software that reads every clause, checks every line, and shows its work.
