InvoiceGuard
InvoiceGuard 🛡️
AI-powered accounts payable invoice matching agent that automates 2-way and 3-way line-item checks to catch pricing errors and quantity overcharges instantly—without requiring a six-figure AP automation platform.
Overview
Every invoice that lands in your inbox has to be checked against what was actually ordered — and, ideally, what was actually received — before you approve payment. Doing that by eye, line by line, on a busy day is exactly how pricing errors and quantity overcharges slip through.
InvoiceGuard does that check for you: upload your Purchase Order and Invoice (and a Receiving Report, if you have one, for a full three-way match), and it extracts every line item, compares quantities and prices against clear tolerance tiers, and returns a structured report telling you exactly what matches, what doesn't, and what to do about it. Built for AP staff, bookkeepers, controllers, and small-business owners who don't have — or don't want — a six-figure AP automation platform just to catch billing errors. No ERP connection, no software install, no setup: just the documents you already have.
Key Features
- Line-item-level 2-way (PO/Invoice) or 3-way (+ Receiving Report) matching
- Configurable or sensible-default tolerance thresholds
- Severity-tiered exception report (Low/Medium/Critical)
- Unmatched and unauthorized line-item detection
- Missing-information flags instead of guessed values — never fabricates a comparison it can't actually verify
- Works from PDFs, photographed paper invoices, or pasted text
- No accounting software integration or setup required
- Clear Approve / Approve-with-Adjustment / Hold-for-Review recommendation
How It Works
- Upload your Invoice (required) and PO (strongly recommended).
- Add a Receiving Report and/or contract rate card for a deeper check, if you have them.
- InvoiceGuard extracts and aligns line items across documents.
- It compares quantities, prices, and terms against tolerance tiers.
- You get a structured exception report with a clear recommendation.
Input & Output Contract
| Component | Description |

Use Cases
- AP clerk processing a stack of daily vendor invoices.
- Controller spot-auditing before a large payment run.

- Bookkeeper reconciling a client's payables.
- Contractor checking subcontractor invoices against signed subcontract POs (a natural fit alongside Bidwise and MarginGuard).
Limitations & Disclaimer
- Limitations: Doesn't connect to accounting software or auto-post approved invoices; can't independently verify goods were physically received beyond what your receiving report states; accuracy on photographed documents depends on image/OCR quality; not a substitute for professional audit on very high-value or legally disputed invoices.
- Disclaimer: InvoiceGuard is a document-comparison and discrepancy-flagging tool, not a substitute for professional accounting, audit, or legal review. Always verify flagged discrepancies before withholding or disputing payment.
