Your own subscription overview on Maxio, built around how you bill your customers.

  • Customers, subscriptions, invoices and usage, straight from Maxio Advanced Billing.
  • AI that spots customers about to churn, with you approving every change.
  • A screen for your team and an email when a big customer cancels.

Ask your chat

Answers straight from your Maxio (Chargify) data, in Claude or another chat with the full Hypamoon connection.

  • Which subscriptions are past due this week?
  • Which customers downgraded their plan last month?

When something happens

Maxio (Chargify) sends a webhook to your app, and the app asks AI what happens next.

  1. When

    A subscription changes state, for example to canceled or past due.

    AI decides

    AI looks at the plan, the payment history and the usage and decides whether someone should call.

    Then

    The account owner gets an email with the summary.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Maxio (Chargify) data.

  • For your customers

    Customers sign in and see their plan, their invoices and what they used this month.

Add Hypamoon

Text messages, email, phone, payments and agents run in the same project as the adapter.

  • Agent on a schedule

    An agent changes a customer's plan when they ask for it, after you approve.

    AI proposes, you approve

Maxio (Chargify) stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Maxio (Chargify) waits for your approval, one call at a time. How adapters work

Good to know

  • Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
  • Maxio Advanced Billing is the former Chargify. Every site has its own subdomain in the API address.
