The Stewards.
Agents that govern the money going out — before it's gone.
A continuous, audit-grade assurance layer that intercepts, validates, and recovers value at every step of the procurement lifecycle.
Invoice Steward
Spend Assurance · Pre-payment
Validates every invoice line against contracts, rate cards and delivery evidence — before payment moves. Discrepancies are caught with a cited rule reference, not a “looks off” flag.
The Invoice Steward sits between AP and payment. It reads every line, reconciles it against the contract stack, and either clears it or stops it — with the rule, the contract clause, and the variance pre-loaded for the reviewer.
Straight-through processing rises, exceptions resolve in minutes, and finance leaders get a live pulse on assurance instead of a monthly back-look.
Intercept
Every invoice, pre-payment
Lines validated against contracted rates, approved POs and commercial entitlements before funds release.
Assurance
Multi-layer, cited
Contract stacks, evidence documents and SLA terms resolve variances deterministically, with cited rule references.
Escalate
Decisions in minutes
Exceptions route to reviewers with confidence scores and pre-loaded actions. Segregation-of-duties enforced.
Spend Steward
What it does
- Continuously scans procurement data to detect off-contract purchases, supplier fragmentation and anomalies eroding negotiated value.
- Benchmarks every supplier engagement against market intelligence and category best practices.
- Converts spend data into prioritized, quantified savings opportunities procurement teams execute immediately.
How it stays safe
- Human approval required before any recommendation executes. Configurable guardrails define thresholds and escalation triggers.
- NL-queryable insights for executives — instant answers without SQL, BI tools or report requests.
- Full audit trail on every insight, decision and action — traceability from detection through realization.
Leakage Steward
Find what was lost. Recover every dollar.
Scans historical and active transactions to identify recovery potential across five proven loss vectors — then builds the evidence-backed case and runs the supplier recovery workflow.
01
Duplicate payments
Cross-invoice matching and pattern detection identify exact and near-duplicate payments with high precision, validated against contracted rates.
02
Missed credits
Open credit memos, unapplied returns, and stranded vendor balances reconciled and routed for collection or offset.
03
Unapplied rebates
Volume tiers, spend thresholds and promotional benefits reconciled — no entitlement left on the table.
04
Rate overbillings
Invoiced rates compared against contracted rates and amendments; overbilled line items surfaced with full provenance.
05
Billing anomalies
Statistical outliers, suspicious patterns, and non-conforming charges flagged with evidence and disposition options.
Margin Steward
Enforces commercial compliance on every transaction — validating pricing against terms, monitoring rebate entitlements and preventing margin erosion in real time, not in a quarterly audit.
Margin protected, real time
Real-time
Variances surface at the transaction, not the quarter. Low-risk drift auto-resolves; material deviations escalate to the right authority with full context pre-loaded.
How it works
Validate & reconcile
Every transaction checked against contracted pricing schedules, amendments and approved exceptions. Rebate eligibility reconciled across tiers automatically.
Tier the risk
Auto-resolve low-risk drift. Material variance escalates to the right authority through risk-tiered routing. Reviewers get the variance and the contract clause, pre-loaded.
Expose, real-time
Live compliance scorecards: leakage prevented, off-contract flags, period-over-period trends. Variance narratives auto-drafted for audit packs.
Supplier Steward
Activate faster. Stay compliant.
Orchestrates the entire KYC/KYB compliance lifecycle — from sourcing trigger to ERP activation — running sixteen parallel validation checks and producing one explainable risk score.
Intelligent intake tailored to entity type, geography and deal value. Documents are auto-extracted; suppliers confirm rather than re-enter, removing the #1 source of onboarding drop-off.
Entity existence, UBO verification, signer authority, tax ID, sanctions, PEP, adverse media and more — all run in parallel, producing a single explainable risk score with cited evidence.
Low-risk cases auto-approve to ERP activation. Exceptions route to reviewers with full rationale and pre-loaded actions; segregation of duties enforced for high-risk cases.
Activated into the ERP supplier master with full evidence chain retained for audit and regulatory examination. Every check, score, decision and override is immutably recorded.
Cycle time, end-to-end: hours, not days
