Automate ONE.KBP with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• Invoice status changes in FIN, every morning

  Build this

  Starts

  Every weekday at 8:00 (Europe/Berlin)

  Step 1

  For each group company you name, check invoice statuses in FIN.

  Step 2

  Keep the invoices whose processing status changed since the last run.

  Step 3

  Email you the list, one section per group company, with the processor for each invoice.

• Payment receipts posted to your accounting system

  Build this

  Starts

  Every weekday at 17:00 (Europe/Berlin)

  Step 1

  For each group company, get the payment receipts and credit notes in FIN.

  Step 2

  Keep the documents that were not there on the last run, and stop when there are none.

  Step 3

  Post each one with its number, date, amount and the invoices it covers to your ERP webhook.

• Weekly list of open delivery notes

  Build this

  Starts

  Every Monday at 7:00 (Europe/Berlin)

  Step 1

  For each group company you name, list the open delivery notes in FIN.

  Step 2

  Add up the open amount per group company with an AI step.

  Step 3

  Email you the summary with every open delivery note listed.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Check invoice statuses in FIN” would look like.

    ],

  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

ONE.KBP’s own options

Volkswagen exchanges logistics data with suppliers by EDI: VDA messages such as delivery schedules, despatch advice and invoices, sent point to point over OFTP2. A CSN network connection gives access to FIS/JIT systems and CAD data exchange. The platform's roughly 80 applications, FIN included, are used in the browser.

Signing in to ONE.KBP

ONE.KBP signs you in with your User ID and password, and applications with sensitive data also ask for a six-digit one-time password from an authenticator app (TOTP). One account reaches every application your roles allow. With Fous you sign in through ONE.KBP's own sign-in with your own account, and the login is sealed with AES-256.

Worth knowing

Roles decide what you see

Your Company Administrator assigns roles in the User Management System. DISCOVERY, for example, appears under Applications only once you have the role DISCOVER:Lieferant.

One-time password for sensitive applications

Strong authentication (TOTP) is mandatory for a range of applications. Registering takes about 30 minutes and must be finished within 24 hours of first clicking the registration link.

FIN shows what each company publishes

Participating group companies make invoices, credit and debit notes, delivery notes and payment receipts available in FIN, each with the processor and their contact details.

Pickup notifications can also go by EDI

Instead of placing them in DISCOVERY, you can send pickup notifications as VDA 4933 EDI messages. A method you build for DISCOVERY needs the same role in your account.
