Your own invoice follow up on Procountor, built around your customers.

  • Invoices, customers and payments, through the API endpoints Procountor opens for you.
  • AI that spots late payers and drafts a friendly reminder, with you approving each one.
  • A screen for your team and a short weekly email for you.

Ask your chat

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

  • Which sales invoices are overdue?
  • Which customers paid later than usual this quarter?

When something happens

Procountor sends a webhook to your app, and the app asks AI what happens next.

  1. When

    Procountor reports a change you subscribed to, such as an invoice update.

    AI decides

    AI looks at the invoice and the customer's history and decides whether a reminder is needed.

    Then

    The account owner gets an email with a draft reminder to approve.

A screen for your team or customers

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

  • For your team

    Your team sees open invoices per customer and which ones need a reminder.

Add Hypamoon

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

  • Email

    A weekly email with the customers who started paying late.

Procountor 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 Procountor waits for your approval, one call at a time. How adapters work

Good to know

  • Procountor signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Procountor takes more work: ask your chat to check this first.
  • Do not put secrets or tokens in request URLs. API certification is needed only to join the Procountor Partner Program.

Try it in your chat

First get access from Procountor. Then fill in what to read and write, and send it.
