Enable Voiceflow usage with subscription plans

Hi everyone. I'm Patrick and I would like to ask for help with a problem designing Voiceflow.
I want users using my VF agent to pay a subscription fee to have it, and pricing plans are designed based on the number of sessions. In addition, I also want to implement single charge for first-time as well as following times.

The billing is processed via Stripe.

Could anyone please recommend a solution to achieve this? Thank you very kindly.

Patrick, you can handle this with Stripe + a simple data connection (Google Sheet or CRM). Here’s how:
When a user starts, the bot asks for their name + email.
Voiceflow then checks your database (via API/Make.com) to see if the user has an active subscription or remaining credits.
If the user is paid up → the chatbot continues.
If their subscription ended or credits are 0 → the bot politely stops and tells them to renew.
This way, Stripe manages payments, your database tracks credits, and Voiceflow only allows access when the user is valid.

Thank you Atim for the logic suggestion
