You're paying invoices. Are you sure they're right?

Manual matching is slow. Errors are expensive.

  • Every invoice needs to match a PO and a receipt. Your team does this manually—open invoice, find PO, compare line items, check quantities, verify prices. 15 minutes per invoice. 200 invoices a day. Do the math.
  • Duplicate payments happen more than you think. Same invoice submitted twice with different formatting. Different invoice number, same amount, same date. Vendor "accidentally" sends the same invoice to AP and to the project manager. $50K out the door.
  • Price variances slip through. PO says $100/unit. Invoice says $105/unit. Buried in a 47-line item invoice. Nobody catches it. You're overpaying 5% on a $200K order. Every month.
  • Math errors are embarrassing. Line items don't add up to the total. Tax calculated wrong. Extended price doesn't match quantity × unit price. Your ERP accepts it anyway. Auditor finds it. You fix it retroactively.
  • Tax code validation is a nightmare. Different rates for different jurisdictions. Exempt items mixed with taxable. Vendor uses wrong tax code. You pay it. IRS notices. Penalties follow.
  • Approval routing is manual and slow. Invoice over $50K needs director approval. Invoice from new vendor needs procurement sign-off. Someone has to look at every invoice to decide where it goes. Bottleneck.

"We did an audit of last year's invoices. Found $1.2M in overpayments. Duplicate invoices that slipped through—$340K. Price variances we didn't catch—$580K. Math errors—$180K. Tax miscalculations—$100K. And that's what we found. We have no idea what we missed. The scary part? Our AP team is good. They work hard. They're just human. Checking 200 invoices a day against POs and receipts? Things get missed. Every single day."

Duplicate Detection

$47K Duplicate Payment Stopped

Same invoice submitted twice. Different filename. Slightly different formatting. Previous system treated them as different invoices. Agent caught it before payment.

Agent Action

"Duplicate invoice alert: INV-PM-2024-1847 ($47,291.00) matches existing invoice INV-PM-2024-1847 processed Dec 3. Same vendor, same amount, same PO reference. File comparison: 94% content similarity despite different filename (invoice_dec.pdf vs PM_invoice_847.pdf). Historical check: This vendor has submitted 3 duplicate invoices in past 12 months. Action: Invoice blocked. Notification sent to AP Lead. Vendor flagged for duplicate monitoring."

→ $47,291 duplicate payment prevented. Pattern identified.
Price Variance

$12K Monthly Overcharge Caught

Vendor invoice shows $105/unit. Contract says $93/unit. PO was entered at wrong price. Invoice matched PO perfectly—both were wrong. Agent caught the contract variance.

Agent Action

"Price variance alert: Invoice INV-2024-8921 from TechSupply Inc. Line item: Widget Assembly (Part# WA-4421). Invoice price: $105.00/unit. PO price: $105.00/unit (3-way match passes). Contract price: $93.00/unit (Contract C-2024-0087, effective Jan 2024). Variance: $12.00/unit (12.9% over contract). Quantity: 1,000 units. Total overcharge: $12,000.00 this invoice. Historical check: Same variance on previous 3 invoices totaling $36,000. Action: Invoice flagged for price review. Notification sent to Procurement. Recommend: Correct PO pricing, recover $48,000 in overpayments."

→ $12K caught. $48K historical overpayment identified for recovery.
3-Way Match

94% Auto-Match Rate Achieved

200 invoices daily. Previously: every one manually matched. Now: 188 auto-matched, 12 exceptions surfaced for review. AP team focuses on exceptions, not routine matching.

Agent Action

"Daily matching summary: December 8, 2024. Invoices processed: 200. Auto-matched (no exceptions): 188 (94%). Total value auto-matched: $2,847,291. Average processing time: 23 seconds per invoice. Exceptions requiring review: 12 (6%). Exception breakdown: Quantity variance (over threshold): 4 invoices. Price variance (over threshold): 3 invoices. Missing goods receipt: 3 invoices. PO not found: 2 invoices. Exception queue: All 12 exceptions routed to appropriate reviewers. Estimated time saved: 47 hours (vs. manual matching). Accuracy: Zero false positives in auto-matched invoices."

→ 188 invoices auto-matched. 47 hours saved daily. Zero errors.
Tax Validation

$8K Tax Error Corrected Before Filing

Vendor charged 8.25% sales tax on exempt items. Tax should have been 0%. Easy to miss in a long invoice. Agent flagged it before payment, avoiding future audit issues.

Agent Action

"Tax validation alert: Invoice INV-2024-7721 from Industrial Equipment Co. Issue: Sales tax charged on exempt items. Details: Line items 4-7: Manufacturing equipment (tax exempt per state manufacturing exemption). Invoice shows: 8.25% tax charged ($8,247.50). Correct tax: $0.00 (exempt). Overstated tax: $8,247.50. Supporting documentation: State exemption certificate on file (EX-2024-0847). Vendor tax-exempt status: Active. Action: Invoice returned to vendor for correction. Credit memo requested. Notification sent to Tax team. Vendor education: Exemption certificate resent to vendor AP department."

→ $8,247 tax overcharge caught. Audit risk eliminated.
