Your own quote and invoice portal on Informer, built around your customers.

  • Relations, quotations, sales orders, sales and purchase invoices, straight from Informer.
  • AI that turns requests from your site into draft quotations, with you checking each one.
  • A portal for your customers and a weekly cash overview by email.

Ask your chat

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

  • Which quotations from last month have not turned into an order yet?
  • Which customers have open sales invoices over 1,000 euro?

When something happens

Informer sends a webhook to your app for some events, and the app asks AI what happens next. For the rest an agent checks every 15 minutes.

  1. When

    A sales invoice or quotation changes in Informer.

    AI decides

    AI decides whether the change needs someone's attention, such as a large quote that was accepted.

    Then

    The right colleague gets an email with a short summary.

  2. Every 15 minutes

    New requests from the form on your own site.

    AI decides

    AI matches the request to an existing relation and picks the products and VAT rate.

    Then

    A quotation is created in Informer for you to check.

    AI proposes, you approve

Add Hypamoon

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

  • Agent on a schedule

    Every Monday, an agent emails you the open sales invoices and what came in last week.

Informer 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 Informer 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.
  • Each API key belongs to one administration and gives full access to it. Webhook deliveries are signed with HMAC-SHA256.
