Your own receivables overview on Upflow, built around how your customers pay.

  • Customers, invoices, payments and credit notes, straight from Upflow.
  • AI that spots customers who start paying late, with you approving every reminder.
  • A screen for your team and a short weekly email for you.

Ask your chat

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

  • Which customers have invoices more than 45 days overdue?
  • How much did we collect this month compared to last month?

On a schedule

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

  1. Every 15 minutes

    Every night, new invoices and payments in your own billing system.

    AI decides

    AI checks each record for a matching customer and a complete amount.

    Then

    The invoices and payments are added to Upflow.

    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 Upflow data.

  • For your customers

    Customers get a link to their own portal with their open invoices.

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 customers who pay later than they used to.

Upflow 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 Upflow 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.
  • Upflow has a sandbox at api.sandbox.upflow.io for testing. For AI assistants Upflow also has its own MCP server.
