Frequently asked questions

Quick answers to common questions.

  • What file formats can I upload?

    AuditDup supports CSV and XLSX payment exports. Upload your vendor payments, and we'll map columns to a standard schema so duplicate detection runs consistently.

  • Is my data secure?

    Your files and analysis run in your workspace. We use industry-standard security and do not share your payment data with third parties.

  • Who is AuditDup for?

    AuditDup is built for accounting teams and firms that need to catch duplicate payments before they become write-offs. Upload, we analyze, you review and export.

  • How does the free analysis work?

    Create an account, upload your payment file, and we run duplicate detection (exact, near-match, and fuzzy rules). You get a clear list of likely duplicates to review and export.

  • How long does implementation take?

    Most teams can upload and run their first duplicate analysis the same day. Mapping fields takes a few minutes for standard payment exports.

    You can analyze large payment exports in CSV or XLSX format. If you have unusually large files, contact support and we will help you with the best import approach.

    AuditDup starts with file-based imports to work with common accounting systems. If you need a specific integration workflow, support can guide your setup.
