Ringup

Ringup adds a payment layer to AI voice agents so businesses can charge callers without making them read card numbers into the phone. The idea is simple: once a caller pays the first time, Ringup remembers them. The next time they call, the system recognizes their phone number the moment the call connects and can charge the saved card with a single confirmation. No app downloads, no card details spoken aloud, no friction that causes people to hang up before finishing.

The first-time payment happens through a secure link sent by text while the caller is still on the line. They tap it, enter their card on a Ringup-hosted page, and complete the transaction on their phone. That card stays on file, tied to their phone number. Every call after that becomes a one-sentence checkout. The agent says the amount, the caller confirms, and the charge goes through in the background while the conversation continues.

What makes this different from bolting a payment processor directly onto your voice stack is the separation of concerns. Card data never touches your agent, your logs, or your transcripts. The sensitive information lives entirely on the Ringup side, which keeps PCI scope away from your voice infrastructure. Charges settle to your existing payment processor account, so you are not switching providers or onboarding to a new merchant system just to take phone payments.

Integration works in two ways depending on how much control you want. The simplest path is a hosted call transfer: your agent forwards the caller to a Ringup payment line when it is time to collect, and the call returns after the transaction finishes. If you want tighter integration, there is an API that lets you keep the caller on your own line and handle recognition, charging, and link sending through direct endpoints. The API supports Vapi, Retell, ElevenLabs, Deepgram, LiveKit, OpenAI Realtime, Pipecat, and Twilio ConversationRelay among others, with Square and Clover as the supported payment processors so far.

The target audience is anyone running an AI phone agent that needs to collect money during the call. That includes appointment-based businesses, delivery services, telehealth providers, and anyone else whose phone conversations end with a charge. The problem being solved is the drop-off that happens when you ask callers to read a sixteen-digit card number aloud. People stumble, hang up, or give up. Remembered checkout reduces that step to yes or no.

Ringup positions itself as a payment orchestration engine that works alongside what you already have rather than replacing it. It does not create new processor accounts or force you off your current stack. It sits between your agent and your processor, handling the identity and card storage layer so the rest of your system stays simple. The documentation is clear and the test mode uses standard test card numbers, so teams can build and verify flows before going live.

Pricing is not published on the site, which suggests custom or usage-based plans. Teams evaluating Ringup should expect to reach out for a quote. The product is clearly aimed at production voice deployments rather than hobbyist projects, so the conversation-based model likely scales with call volume. For businesses already running AI voice agents and losing conversions at the payment step, this is the missing piece that makes phone commerce practical.
