The Two-Phase Partnership Model
Phase 1: The 12–24 Month Historical Look-Back (Zero Upfront Budget)
How It Starts
Securely upload 12 to 24 months of de-identified accounts payable disbursement ledgers and vendor master contracts via our encrypted portal.
Algorithmic Reconcilement
Our engine cross-references historical item lines against contract terms, isolating packaging multiplier shifts (e.g., box-of-10 billed at "each" rates), unauthorized catalog inflation, and unapplied volume discounts.
Court-Ready Deliverables
You receive an itemized Dispute & Recovery Schedule complete with pre-drafted vendor credit request packets.
Pure Performance Pricing
25% contingency fee on verified recoveries. You retain 75% of every dollar returned or credited to your health system. If our audit identifies no verified overcharges, you owe zero.
The Two-Phase Partnership Model
Phase 2: Dedicated AP Gatekeeper SaaS Subscription
Your Own Private Dashboard
Following your historical recovery audit, your materials management and accounts payable teams receive their own dedicated, secure Onyx Sentinel web dashboard.
Self-Service Pre-Payment Auditing
Before executing bi-weekly or monthly payment runs, your AP staff drops raw disbursement exports directly into your private portal.
Instant Discrepancy Flagging
Within minutes, the system reconciles pending invoices against your approved contract baselines, allowing your team to place holds on disputed line items prior to check release.
Flexible Budgeting
Transparent tiered annual subscription, billed upfront annually or in convenient quarterly/monthly installments.
Experience the Gatekeeper in Action
Explore how our deterministic engine flags packaging multiplier errors, vendor price drift, and duplicate line items using a representative community hospital dataset.
Implementation Fee Waiver: Standard enterprise onboarding, vendor catalog indexing, and AP team orientation is valued at $7,500. When your facility transitions into an annual subscription within 30 days of receiving your Phase 1 Historical Recovery Audit results, the onboarding fee is 100% waived.
Data Governance, HIPAA, & Security
Zero-PHI Guarantee
The engine analyzes purely financial disbursement data: vendor names, item numbers, unit of measure, quantity, and dollar amounts. No patient identifiers, clinical records, or protected health information ever enter the environment.
Client Data Isolation
Each subscribed hospital operates within a strictly partitioned tenant space. Uploaded files are processed in-memory for audit generation and are never pooled, monetized, or shared.
Encrypted File Transfer
All data transit utilizes enterprise-grade 256-bit TLS/SSL encryption.
