From ingesting invoices across Oracle and SAP to classifying exceptions, running 3-way match validation, and routing approvals — Lumi agents resolve AP exceptions end to end with full audit traceability.
Invoice exceptions are deceptively complex. Lumi resolves them at scale.
PO mismatches, missing GRNs, duplicates, price variances, and tax discrepancies — each exception type requires different data sources, validation logic, and approval workflows. Lumi agents handle them all.
50+
Exception types handled
PO-Invoice Mismatch
Detects quantity, price, and line-item discrepancies between purchase orders and invoices — flagging variances that exceed configurable tolerance thresholds.
<2s per invoice
3-Way Match Validation
Automatically validates invoice against purchase order and goods receipt — confirming quantities, prices, and delivery before approving payment.
PO + GRN + Invoice
Duplicate Detection
Identifies duplicate invoices using fuzzy matching on vendor, amount, date, and line items — preventing double payments even when invoice numbers differ.
Fuzzy matching
Price Variance Analysis
Analyzes price differences against contract terms, historical pricing, and tolerance bands — distinguishing legitimate price changes from billing errors.
Contract-aware
Tax & Compliance Checks
Validates tax calculations, withholding requirements, and regulatory compliance — ensuring invoices meet jurisdictional rules before payment processing.
Multi-jurisdiction
Vendor Master Validation
Cross-references invoice details against vendor master data — verifying bank accounts, payment terms, and vendor status before routing for approval.
Fraud prevention
The Challenge
AP exception handling is a bottleneck
AP teams spend hours manually researching mismatches, chasing approvals, and reconciling invoices across disconnected systems. Exceptions pile up, payments stall, and vendor relationships suffer.
Today
Manual research, endless back-and-forth
Analysts manually research each mismatch across multiple systems
Spreadsheet-based matching with no real-time validation
Duplicate invoices slip through and cause double payments
Email-based approval routing with no escalation tracking
With Lumi
Intelligent resolution, end-to-end automation
AI classifies and resolves exceptions automatically
Real-time 3-way match validation across PO, GRN, and invoice
Duplicate detection with fuzzy matching prevents double payments
Smart routing with escalation rules and SLA tracking
How It Works
A four-stage exception pipeline
Lumi agents process each invoice exception through a structured pipeline — ingesting data, classifying issues, resolving mismatches, and routing approvals.
1
Ingestion
Invoices ingested from Oracle, SAP, and email — parsed, normalized, and matched to POs
2
Classification
AI classifies exception type, severity, and root cause — routing to the right resolution path
3
Resolution
3-way match validation, duplicate checks, and price variance analysis resolve exceptions automatically
4
Approval
Unresolved exceptions routed to approvers with full context, audit trail, and SLA tracking
Agents at Work
Specialized agents for every AP task
A coordinated team of AI agents — each handling a distinct accounts payable function — working together to resolve invoice exceptions faster and prevent payment errors.
Invoice Intake
Ingests invoices from multiple ERP systems, email, and EDI channels — parsing header and line-item data, normalizing formats, and matching to purchase orders automatically.
Exception Classifier
Analyzes each exception to determine type (PO mismatch, missing GRN, duplicate, price variance) and severity — routing to the appropriate resolution workflow.
3-Way Match Engine
Validates invoice against purchase order and goods receipt — confirming quantities, unit prices, and delivery terms match within configurable tolerance bands.
Price Variance Analyzer
Compares invoiced prices against contract terms, historical pricing, and market benchmarks — distinguishing legitimate changes from errors requiring vendor follow-up.
Approval Router
Routes unresolved exceptions to the right approver based on amount thresholds, vendor category, and exception type — with SLA tracking and automatic escalation.
Compliance & Audit
Maintains complete audit trail for every exception — recording resolution rationale, approver actions, and supporting documents for SOX compliance and internal audit.
Use Cases
Where Lumi excels
Built for the operational complexity of accounts payable — not generic document processing.
01
AP Invoice Processing
Automate end-to-end invoice processing — from ingestion and validation to 3-way matching and payment approval — across Oracle, SAP, and legacy ERP systems.
02
Vendor Dispute Resolution
Resolve pricing disputes with vendors using contract-aware analysis — surfacing supporting documentation and generating dispute correspondence automatically.
03
Multi-ERP Consolidation
Consolidate invoice exception handling across multiple ERP instances — normalizing data, deduplicating vendors, and applying consistent resolution policies.
04
Period-End Close Acceleration
Clear exception backlogs before period-end close — prioritizing high-value exceptions and auto-resolving matching invoices to accelerate financial reporting.
