## Summary

Sierra announced a partnership with Stripe on October 20, 2026, allowing customers to pay and receive receipts during AI agent phone calls. The integration removes the need to switch systems or use payment links, keeping the conversation, transaction, and confirmation on a single line. When a payment is initiated, the agent enters a secure mode where customers enter card details via keypad, routed directly to Stripe for processing.

Healthcare payments company Cedar was among the first to use the feature. Cedar’s agent, Kora, helps patients resolve billing questions and pay simultaneously. Sierra reported that 71.3% of calls where patients begin a payment with Kora end in a successful transaction. Cedar’s Chief Strategy Officer Dugan Winkie noted that this closes the gap between answering questions and processing payments, reducing patient anxiety.

The partnership extends Sierra’s earlier launch of Level 1 PCI-compliant payments in April 2026. Sierra’s platform is now listed in the Stripe App Marketplace as a free app, allowing businesses to connect their agents to Stripe accounts without custom integration. The collaboration also includes work on the Personal Agent Protocol, an open standard with Meta, Shopify, and Walmart, aimed at defining how personal agents handle payments and interactions with businesses.

## Key points

- Sierra and Stripe enable customers to pay and receive receipts during AI agent phone calls.
- Cedar’s agent Kora achieves a 71.3% successful payment rate for calls where payment starts.
- Sierra’s platform is listed in the Stripe App Marketplace as a free integration tool.

## Why it matters

This integration reduces friction in AI-driven customer service by enabling seamless transactions within conversations. It supports the shift of AI agents from support tools to revenue-generating channels, particularly in sectors like healthcare where billing complexity is high.
