Annual Cost Breakdown: Current vs Automated

Prevent Duplicate Payments

Organizations typically achieve substantial risk reduction and cost savings through automated duplicate detection

Get Started

Automated duplicate payment detection systems use multi-dimensional matching algorithms to identify duplicates before payment execution. These systems typically achieve substantially higher detection rates than manual processes while reducing the labor required for identification and recovery efforts.

The value of duplicate prevention extends beyond direct cost recovery to include audit efficiency, vendor relationship protection, and internal control strengthening. Organizations often see material reductions in unrecovered amounts and investigation costs through systematic automated detection.

Why Duplicate Payment Prevention Value Matters

Duplicate payments represent one of the costliest avoidable AP errors. Organizations can lose a meaningful portion of total AP spend to duplicate payments, representing substantial costs annually for mid-sized companies. Manual duplicate detection may catch only a portion of duplicates because it relies on spot-checking and manual review of invoice numbers, amounts, and vendor names. Subtle variations in invoice formatting or vendor naming can defeat manual detection.

Automated duplicate detection can catch significantly more duplicates through comprehensive checks across multiple data points: invoice numbers, amounts, dates, vendor IDs, PO numbers, and fuzzy matching on vendor names and amounts. The system checks every invoice against all historical payments and pending invoices in real-time, flagging potential duplicates before payment execution. This high-accuracy detection can eliminate most duplicate payment losses.

Beyond direct financial savings, automated duplicate detection protects against fraud schemes that exploit duplicate payment vulnerabilities, eliminates the time-consuming vendor refund process, improves audit outcomes by demonstrating strong financial controls, and frees AP staff from manual duplicate checking. The reputational and relationship benefits of not overpaying vendors add additional value.

Frequently Asked Questions

How common are duplicate payments?

Duplicate payments can occur in organizations without automated detection, with rates influenced by invoice volume, multiple payment systems, and staff turnover. Organizations with strong manual controls may achieve lower rates, while those with weaker controls can see higher rates.

What causes duplicate payments?

Common causes include receiving duplicate invoices from vendors, paying both PO-based and non-PO invoices for same delivery, processing both original and corrected invoices, system errors during batch processing, and insufficient matching against historical payments.

How does automated detection work?

Systems check every invoice against all historical payments and pending invoices, comparing invoice numbers, amounts, dates, PO numbers, and vendor IDs. Fuzzy logic catches near-duplicates with slight variations. Checks occur in real-time before payment execution.

What happens when a duplicate is detected?

The system flags suspected duplicates for AP review before payment. AP staff investigates whether it is truly a duplicate or a legitimate rebill, supplemental invoice, or similar transaction. Confirmed duplicates are rejected from payment batch.

Can we recover duplicate payments?

Recovery varies by vendor and timing. Recovering from large vendors with robust AR processes can be easier. Small vendors or old duplicates may be harder to recover. Recovery takes AP staff time for vendor communication and documentation.

Does automation catch all duplicates?

Automated detection can achieve very high accuracy by checking multiple data points. Some edge cases like legitimate rebills that look identical to original invoices may require human review. Automation typically significantly outperforms manual detection.
