Even the best ERP misses them. We find the real ones, using targeted routines built on deep ERP experience, sharpened by AI to strip out false positives.
We track the root cause so you can stop them at the source.
Point AI at your AP data and it will flag ‘duplicates’ all day: most of them false positives. Chasing that noise wastes your team’s time and erodes trust in the results. We do it differently.
Built from decades of knowing how ERP systems work, and exactly where they let duplicates through, our routines target those failure points instead of blindly scanning everything.
AI then tunes the results, filtering out the false positives that generic “point AI at the data” approaches drown you in.
What reaches your team is signal, not noise: real, documented, recoverable duplicates.
Most AP systems only flag a duplicate when every field matches exactly, so “0123” vs “123”, a changed invoice date, a different amount, or a different currency can all slip through.
An unclean vendor master is one of the biggest causes: the same invoice can be paid under two vendor records.
P-Card use has grown fast. If something is paid by card and also processed as an invoice, how would your system know?
Bolt-on automation often lacks duplicate-payment identification, letting duplicates through.
Vendors submitting through a portal and by email, plus resubmissions and re-keying, can cause the same invoice to be processed twice.
AP.guru reviews every transaction across vendors, business units, and systems, using AI-driven matching to find what standard controls overlook.
Every duplicate we identify is tagged with its root cause. Over time, that turns one-off recoveries into a map of the systemic issues driving leakage, so you can address the source and prevent the next one.
Manual keying errors, such as transposed invoice numbers, wrong dates, or amounts, create near-duplicates standard controls miss.
Interface and integration errors that re-load or re-process the same invoices across systems.
The same vendor set up more than once, letting one invoice pay under two records.
Trend these root causes and recovery becomes prevention: target training, fix a feed, or clean the vendor master before the next duplicate is ever paid.
