Case Study: PetLab Co. achieves early detection of invoice anomalies and reduced month‑end stress with Stampli

How Unusual Invoice Alerts gave leverage back to PetLab Co and eased their end-of-month

PetLab Co., a direct-to-consumer pet supplement brand, faced recurring end-of-month pressure as its AP team struggled to spot and investigate unusually large or unexpected invoices. To address this, Financial Controller George Koukoumpanis adopted Stampli’s Unusual Invoice Alerts to detect invoice anomalies earlier in the month.

Stampli’s Unusual Invoice Alerts scans new invoices against historical billing patterns and notifies up to five designated recipients, enabling quick investigation and in-platform vendor communication with a full audit trail. Using Stampli, PetLab Co. caught a 33% unexpected vendor price increase (and Stampli has even flagged a 1000% spike in another case), reducing month-end stress, protecting cash flow, and helping preserve vendor relationships.
