4-Way Invoice Matching.
Where contract becomes cash.
Leah matches every invoice against the contract, PO, and receipt simultaneously. Three domains, one orchestrated flow. Financial leakage surfaced before payment, not after.
The contract is the source of truth. Most matching pretends it isn't.
Three-way matching ignores the contract
PO, receipt, and invoice match against each other but not against the contract that governs them. Pricing schedules, SLA penalties, volume discounts, and payment terms negotiated months ago never make it into the reconciliation.
Pricing variances buried in invoices nobody reads
Vendors quietly invoice at list price when contract pricing applies. Tiered discounts go unclaimed. Surcharges appear without authorization. By the time finance closes the books, leakage is already paid.
SLA penalties never claimed
Service levels are agreed in contracts, missed in operations, and forgotten in billing. The credits and penalties owed to the buyer accumulate quietly because no system connects performance data to invoice validation.
Reconciliation happens after the fact
Finance discovers issues at quarter-end audit, not at invoice receipt. Recovery requires uncomfortable vendor conversations, manual claims processes, and write-offs of leakage that has already cleared.
Contract amendments do not flow to AP
When pricing or terms change mid-contract through addenda, change orders, or annual renegotiations, the AP system keeps validating against the original signed version. The newest agreement is the one nobody sees.
Vendors paid for terms they did not honor
Late deliveries, partial fulfillments, and quality breaches each entitle the buyer to remedies under the contract. Without a unified validation layer, the remedies are theoretical and the full invoice amount gets paid.
From signed PDF to live commercial data
Leah reads every contract you have, extracts the terms that govern reconciliation, and structures them as a queryable data layer. Pricing schedules, SLA thresholds, payment terms, volume tiers, penalties, and renewal triggers all become first-class data the matching engine can use.
“We ran Leah against eight years of supplier contracts. The first scan surfaced pricing tiers we had been entitled to but never claimed. That alone justified the project.”

Five steps to commercial intelligence in your invoicing
Leah integrates with the systems you already run. No rip and replace. Value from the first invoice run.
Connect
Leah integrates with your CLM, ERP, AP, and procurement systems. Contracts, POs, receipts, and invoices all flow into a single intelligence layer without replacing any of your existing systems.
Extract Contract Truth
Every contract is read, parsed, and structured. Pricing, payment terms, SLAs, penalties, and renewal triggers become live data, with amendments and addenda continuously updated.
Match in Four Dimensions
Each invoice is validated simultaneously against the contract, PO, and goods receipt. Variances are flagged, classified, and routed before payment release.
Resolve and Recover
Exceptions route to the right function with full context. Closed-period leakage is identified retrospectively, with claims generated for recovery.
Govern Continuously
Every match, exception, and resolution is logged with timestamps and rationale. Audit prep takes minutes, not weeks.

Three-way matching validates the PO against the receipt against the invoice. It assumes those three sources are correct. Four-way matching adds the contract as the fourth, governing source. Pricing schedules, SLA terms, volume discounts, and penalty clauses all become inputs to the match. Variances against the contract are caught at invoice time, before payment, instead of at quarter-end audit, after payment.
No. Leah operates on top of your existing ERP, AP, CLM, and procurement systems. Contracts, POs, receipts, and invoices continue to live where they live today. Leah reads from those systems, runs the validation layer, and writes back exception routing and approval decisions. There is no rip-and-replace, and no disruption to existing AP workflows.
Amendments, change orders, and renegotiated pricing flow into the same structured data layer as the original contract, with effective dates preserved. When a new invoice arrives, Leah applies the version of the contract that was in force when the goods or services were delivered, not the original signed version. Mid-contract pricing changes are reconciled correctly without manual intervention.
Leah handles non-standard contracts because she reads the actual document, not a structured template. Bespoke pricing schedules, custom SLA frameworks, master agreements with multiple addenda, and industry-specific clauses are all extracted with audit-grade accuracy. Where extraction confidence is below threshold, the term is flagged for human review before it enters the matching engine.
Most customers see retrospective leakage surfaced within the first 30 days, as Leah scans closed periods against the governing contracts. Forward-looking variance prevention starts at the first invoice run after deployment. Recovery claim acceptance from vendors typically follows within 60 to 90 days, depending on the relationship and the size of the recovery pool.
Yes. Leah is deployed by major manufacturers, energy companies, and pharmaceutical firms with strict data security requirements. Contract content does not train Leah's underlying models. Customer data is encrypted in transit and at rest. SOC 2 Type II, GDPR, CCPA, HIPAA-ready, and ISO 27001 aligned. Private instance deployment is available for customers with strict data isolation requirements.
