Signal Algar Telecom's AI agent reviewed 25% of first invoices and captured USD 1.5 million in nine months

Summary

Deloitte cites Algar Telecom, a Brazilian telecommunications company, as an early example of an AI agent producing measurable results in finance. In 2024 the company introduced an agent called Billy into its finance function. CFO Gustavo Matsumoto explains that in his industry most billing mistakes appear on the first invoice sent to a new customer. Billy was therefore assigned to review those invoices by checking the contract against the data entered in the CRM system and the invoice itself. In the first nine months of 2025, the agent reviewed a quarter of all first invoices issued. Over that period it captured an additional USD 1.5 million in profit.
