Your own client portal on inFakt, with invoices and payments in one place.

  • Clients, invoices, products and payments, straight from inFakt.
  • AI that drafts invoices from orders and follows up unpaid invoices, with you approving every change.
  • A portal for your clients and a short weekly email for you.

Ask your chat

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

  • Which invoices are unpaid after their due date?
  • How much did we invoice per client this quarter?

When something happens

inFakt 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

    An invoice changes in inFakt.

    AI decides

    AI checks whether it was paid, is late or needs a correction.

    Then

    You get an email when a client needs a reminder.

  2. Every 15 minutes

    New orders from your own web form that are not invoiced yet.

    AI decides

    AI matches the client and the services and checks the VAT.

    Then

    An invoice is created in inFakt.

    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 inFakt data.

  • For your customers

    Clients sign in and see their own invoices and payment status, straight from inFakt.

inFakt 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 inFakt 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.
  • Invoices are created asynchronously, so an adapter checks the task status before the invoice is ready. Webhooks are verified once and signed with the X-Infakt-Signature header.
