I will audit contracts for supplier overcharges contract invoice reconciliation


About this gig
Are you overpaying suppliers or missing money in contracts and invoices? I will audit your contracts, purchase orders and invoices to find discrepancies, supplier overcharges, duplicate charges, missed rebates, unauthorized fees and billing errors.
My contract invoice reconciliation compares what your agreement says should be charged with what was actually invoiced. I can extract contract terms, payment terms, approved surcharges, discounts, credits and key commercial terms, then match them against invoice data and document the exceptions.
You receive:
- Contracted price vs invoic ed price
- In voice/PO discrepancies
- Duplicate or unsupported charges
- Missed credits, rebates or discounts
- Price increases needing verification
- Evidence/reference for each finding
- Difference amount and next actions
- Excel reconciliation tracker
Built for businesses, procurement teams, finance/AP teams, ecommerce operators, agencies and companies managing contracts and billing.
Send your contracts and invoi ces. I'll turn scattered documents into an actionable contract compliance and money-leak report.
Notes: administrative/commercial reconciliation only; not legal advice. Made for action now.
