Accounts payable teams lose 0.1–0.5% of total spend to duplicate payments that evade standard system checks due to subtle variations in invoice numbers, supplier names, and other data quirks.

Standard AP systems only catch exact duplicates; they miss variations like punctuation differences, name variants, reminder invoices, split entries, and orphaned credit notes.

Workarounds Described

Uses Excel SUBSTITUTE to normalize invoice numbers before running COUNTIFS
Manually cleans supplier names into separate column (strip Ltd/Limited/punctuation)
Runs conditional checks on supplier + amount + date ±60 days to find reminders
Groups by supplier + week + category to detect split entries below approval limits
Manually cross-references negative entries (credit notes) against paid invoices

Implied Software Gaps

Automated normalization of invoice numbers and vendor names to catch variant duplicates
Automated detection of same-amount-different-reference invoices within a date window
Automated matching of credit notes to paid invoices with alert for orphans

App Concept

DuplicateDetect AI

An AI-powered AP audit tool that automatically normalizes invoice and vendor data, then runs multi-pattern checks for duplicate payments. Unlike generic ERP modules, it catches subtle variants, split entries, and orphaned credits, recovering significant spend without manual Excel work.

Key Features

Automated invoice number normalization (strip punctuation, spaces, case)
Supplier name fuzzy matching (Ltd/Limited, punctuation variants)
Amount + date proximity matching to catch reminder invoice duplicates
Split entry detection (lines summing to round totals near approval limits)
Orphaned credit note alert (unapplied credits against paid invoices)

Target Users: Recovery auditors and AP managers in mid-sized businesses (50-500 employees) across industries like manufacturing, retail, and professional services

Revenue Model: $99/mo per company for up to 5,000 invoices/month, with $199/mo enterprise tier for unlimited invoices and multi-entity support
