Non-PO Invoice Validation.
Contracts as the missing PO.
Leah validates non-PO invoices against the underlying contract or MSA, applies cost center and approval matrix rules, surfaces deviations, and routes to the right approver with full context.
Direct invoices bypass procurement. The contract is the only control left.
Non-PO spend invisible to procurement
Direct invoices skip the requisition flow entirely. Procurement learns about the spend after AP has already coded it. Category strategies, preferred suppliers, and negotiated rates simply do not apply to invoices that never touched the procurement system.
Contract terms never applied to invoices
The MSA defines the rate card, the rebate schedule, and the cap on professional fees. The invoice quotes a different number. Without a system tying the contract to the invoice, AP has no way to know whether what the vendor billed matches what was agreed.
Approval matrix fragmented across systems
Authority limits sit in the ERP, delegation rules sit in HR, cost center owners sit in a finance spreadsheet, and the actual approvals happen over email. AP reconstructs the right approver invoice by invoice. Mistakes are quiet and frequent.
Recurring services billed without active contracts
Utilities, software subscriptions, and outsourced services keep invoicing month after month, often after the underlying agreement has expired or been superseded. Nobody catches it because the invoice looks identical to last month.
Tail spend uncategorized and unmanaged
Long tail of small-dollar invoices gets coded to generic GL accounts to keep the queue moving. Real category insight, supplier consolidation opportunities, and policy violations all disappear into the same catch-all bucket.
Reporting gaps for the CFO
When the CFO asks what the company is spending on professional services or facilities, finance pulls the data and procurement pulls a different number. Non-PO spend is the gap. Nobody can answer cleanly because the source data was never structured.
Every non-PO invoice tied to its governing agreement
Leah reads every active contract and MSA, structures the rate card, fee caps, and term commitments, then maps each incoming non-PO invoice to the agreement that governs it. The contract becomes the missing PO. Pricing is checked, scope is validated, and out-of-scope charges are flagged before approval.
“Two thirds of our spend was non-PO and effectively ungoverned. Leah turned every MSA into a live ruleset that the AP team can actually enforce.”

Five steps from direct invoice to controlled, coded, approved
Leah operates on top of the systems you already run. No rip and replace. Value from the first non-PO invoice run.
Receive Non-PO
Direct invoices arrive through email, vendor portals, or AP capture. Leah ingests them, extracts header and line detail, and recognizes the supplier and cost center.
Map to Contract or MSA
Leah resolves the agreement governing the invoice. Rate cards, fee caps, scope boundaries, and effective dates are loaded as the validation ruleset.
Apply Approvals
The unified approval matrix selects the right approver based on amount, category, cost center, and current delegations. The contract clause is attached to the request.
Validate Recurrence
If the invoice is recurring, Leah confirms the agreement is still active and the amount sits inside the agreed range. Drift, duplicates, and expired contracts are flagged.
Code & Approve
On approval, the invoice is coded to the right category, supplier, and cost center. A complete audit trail is preserved for finance and procurement reporting.

Non-PO invoices, also called direct invoices, are invoices that arrive without a purchase order to match against. They are common in services spend, professional fees, utilities, real estate, and recurring subscriptions. Three-way matching does not apply, so AP teams fall back on contract terms, master service agreements, and approval workflows that often live outside the ERP. That is exactly the gap Leah closes.
Leah maps every supplier in AP to its governing agreement during onboarding. When an invoice arrives, she resolves the contract version that was in force on the service date, applies the rate card and scope, and flags variances. Where multiple agreements could apply, she picks the most specific one and shows the reasoning so a reviewer can confirm.
Leah ingests authority limits from the ERP, delegation rules from the HR system, and cost center ownership from finance, then merges them into a single rules engine. When any source changes, the matrix updates. The right approver is resolved at routing time based on amount, category, cost center, and current delegations.
Leah holds the invoice, flags it as billing without an active agreement, and routes a notification to the category owner and procurement. The flag includes the last known contract, its expiry date, and the cumulative amount paid since expiry. Finance decides whether to renegotiate, terminate, or temporarily approve while a new agreement is signed.
Every non-PO invoice is classified into a consistent category, sub-category, supplier, and cost center taxonomy at intake. Reporting views are built from that classification, so finance and procurement reconcile by design. The CFO gets one number for what the company spends on each category, broken down by business unit and approver.
No. Leah operates on top of the systems already in place. Invoices continue to flow through the ERP and AP automation tool, contracts continue to live in the CLM or document repository, and approvals continue to post back to the system of record. Leah adds the contract reconciliation, the unified approval matrix, and the recurring spend watch as a layer over the existing stack.
