Common duplicate patterns
The same invoice posted twice, a credit entered as a second invoice, or a scanned PDF keyed again after an EDI load.
Free tool
Upload an invoice export and map invoice number, plus vendor, amount, and date when you have them. Groups that share only an invoice number are labeled possible duplicates.
The checker groups rows that share the mapped columns. It does not guess similar invoice numbers or near-amount matches.

Vendors reuse numbers across entities, or two suppliers can issue INV-100. Adding vendor and amount turns a possible duplicate into a stronger exact group.
It will not label fuzzy or similar invoices as definite duplicates. Those need a person, or the full vendor reconciliation workflow.
Continue with the full workflow, or try another free check.
Compare supplier statements to AP and find missing invoices, credits, and payment differences.
Three-way check purchase orders, invoices, and goods received notes from spreadsheet exports.
Matched, only on the statement, only in internal records, and amount differences
Present in both, missing from either side, and possible duplicates
Anonymous uploads are processed in memory for this check only. They are not saved to an AuditExport workspace and are discarded when the request finishes.
CSV and .xlsx, depending on the tool. Legacy .xls, password-protected workbooks, and ZIP batches are not accepted here.
The free checker accepts up to 2 files, each file up to 1.5 mb, and 2,000 data rows per file. Larger work belongs in an AuditExport workspace.
No. Files are read in memory for this check. Nothing is written back to the file you selected.
No. These pages run a limited, exact check so you can see the problem. AuditExport adds tolerance, multi-way matching, review, reports, and saved workflows.
No. The checker reports what it can see in the files. It does not post journals, close a period, or replace professional judgment.
Review duplicate groups with the rest of the AP file, then keep the setup for next month.
