What this invoice checker reviews
Payment Check is an online invoice checker. Upload the invoice and the quote, purchase order, or other document it should agree with. The report flags differences that are worth a second look before you pay.
- Price, quantity, subtotal, and total differences
- VAT and other tax figures that do not follow the line items
- Dates, payment terms, and invoice details that disagree
- Arithmetic and consistency issues visible on the documents
Who uses invoice review this way
Teams use it as a second pair of eyes: accounts payable and procurement reviewing a supplier or vendor invoice, finance checking invoice matching against a purchase order or quote, and freelancers or small businesses checking a bill before they pay it.
It does not replace your accounting system, approve a payment, or perform three-way matching against goods receipts. You still review the findings.
How to check an invoice here
1
Upload both documents
Add the invoice and the supporting quote or purchase order as a PDF or image.
2
Compare the figures
The check compares line items, tax, dates, and totals instead of asking you to re-key every number.
3
Review before you pay
Use the discrepancy report to decide what to query with the supplier. Results do not approve or reject payment.
