Your own invoice flow on Billingo, built around how your customers order.

  • Invoices, partners and products, straight from Billingo.
  • AI that drafts the invoice from an order and flags missing tax numbers, with you approving before it is issued.
  • A screen for your team and a short weekly email for you.

Ask your chat

Answers straight from your Billingo data, in Claude or another chat with the full Hypamoon connection.

  • Which invoices from last month are still unpaid?
  • Which partners did we invoice most this quarter?

On a schedule

Billingo has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next.

  1. Every 15 minutes

    New orders in your web shop that have no invoice yet.

    AI decides

    AI checks the buyer's details and tax number and prepares the invoice.

    Then

    The invoice is issued in Billingo after you approve it.

    AI proposes, you approve

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Billingo data.

  • For your customers

    Customers sign in and download their invoices, straight from Billingo.

Add Hypamoon

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

  • Agent on a schedule

    Once a week, an agent emails you the invoices that passed their due date.

Billingo 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 Billingo 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.
  • Use a read only key for reporting. V2 keys still exist but Billingo recommends V3 for new connections.
