Hermes tests overdue-invoice email and SMS follow-up

Percy Kintu demonstrates a Hermes invoice-follow-up workflow using a test customer whose contact details are his own. He creates an overdue QuickBooks invoice, connects the finance and communication services through Composio, and gives the agent a Google Sheets tracker and business-specific communication rules.

In the reported run, Hermes finds three unpaid invoices. Kintu explicitly asks it to send an email and SMS for a four-thousand-dollar test balance. Both messages arrive with a Stripe link showing the balance under the customer's name. He replies with an awkwardly worded promise to pay the next day; Hermes responds and records the exact reply beside invoice, balance, due-date and contact information in the tracker.

This verifies a controlled reminder-and-reply test, not recovery of a real customer's overdue payment. Kintu owns AgentCall, the SMS product used in the demonstration, and the article promotes implementation services. He also warns that a newly provisioned number can take time before it delivers texts. The copyable sequence is to use one's own contact details for the first invoice, verify that both channels link to the same balance, then inspect the recorded reply before expanding the scheduled process. No paid invoice or verified cash-flow gain is established.
