PO row 2 ↔ invoice row 2 ↔ prior row 2A workflow you can inspect
Let AI read. Check the numbers. Keep the decision.
- 1
Prepare the documents
Paste spreadsheet rows here, or give your AI assistant a PO, invoice and earlier invoices. Confirm the fields before checking.
- 2
Confirm the important fields
Check currencies, units, line references and missing values. Then run the local MCP or this browser workbench.
- 3
Resolve the exceptions
Export the report and an unsent supplier query. Receipt, tax and payment checks stay with your team.
Document reading depends on your AI assistant. This beta does not include PDF/OCR extraction or an ERP connection. Follow the beginner setup guide →
Try the review
One order. One invoice. Every difference visible.
No documents loaded
START WITH YOUR SPREADSHEET
Paste rows. Match columns. Confirm.
Copy cells from Excel or paste a CSV, including headers. Nothing is uploaded. Keep IDs, currencies and units exactly as written.
All amounts need decimal points: 2.50, not 2,50. The table import starts with earlier invoice history unknown. Add prior invoices in advanced JSON to check cumulative billing.
Advanced: structured JSON & earlier invoices
Two-way document check. Source references are supplied by the caller. A clean report does not authorize payment.
Connect it to your workflow
A small tool inside the assistant you already use.
Four MCP tools, one guided review prompt, exact decimal calculations and an evidence trail. Runs locally with no API key or model charges from TradeCheck.

Help us check the need
In the last 30 days, how often did you manually check a supplier invoice against a PO?
Optional. Clicking records only the anonymous answer category.
Clear scope from the start.
What does it catch?
Different supplier or PO references, currency differences, changed unit prices, cumulative billed quantities above the order, duplicate supplied IDs, mismatched SKU or unit, and arithmetic inconsistencies. Partial invoicing is shown as informational.
Is this an autonomous finance agent?
The MCP gives your AI assistant a guided review workflow and deterministic tools. The assistant can help extract data using its own file-reading capabilities. TradeCheck does not pay invoices, contact suppliers, verify delivery or modify accounting systems.
Can I use a PDF or an image?
Give it to a compatible AI assistant and follow the supplied workflow. Review the extracted fields before checking. The browser workbench accepts CSV, pasted spreadsheet rows and structured JSON; built-in PDF/OCR extraction is not available.
What about foreign currency, credits or tax?
Supported currency codes are USD, EUR, GBP, CAD, AUD, CNY, SGD, CHF and JPY. Both documents must use the same currency for price comparison. No FX, unit conversion, credits or discounts. Tax and charges enter the arithmetic but their correctness is not verified.
