Duplicate Invoice Prevention Checklist
How duplicates get in, the controls that stop them at entry and at payment, the monthly sweep, and the recovery procedure.
• Automate faster • Collaborate better
• Pay with confidence
Duplicate payments have a distinctive property: the counterparty who notices usually benefits from staying quiet. That makes prevention worth more than detection, and detection worth more than hoping vendors are honest.
This checklist covers all three layers: seven controls at entry (where duplicates are cheapest to stop), four at payment, a monthly three-query sweep that takes about thirty minutes, and a recovery procedure that ends with root cause. Recovering a duplicate without fixing its entry point is a subscription, not a fix.
