Abrechnung: Wie die B2B-Rechnungsstellung funktioniert

Hier geht es NICHT um Ihre Stromrechnung. Hier geht es darum, wie Energieunternehmen untereinander abrechnen — MSB rechnet mit NB ab, NB mit LF — alles über EDIFACT INVOIC und REMADV.

Drei Arten von B2B-Rechnungen

When you pay your electricity bill, you are paying one company — your supplier. But behind that, your supplier has already received invoices from the grid operator and the meter operator. Everyone bills everyone else, and it all flows through EDIFACT INVOIC messages. REMADV closes the loop when payment happens.

Three Invoice Types in the Energy Market

NBLF

Netznutzungsrechnung

Grid Usage

The grid operator bills the supplier for accessing the grid on behalf of their customers. Based on actual MSCONS readings. Largest invoice type.

INVOIC + REMADV

MSBNB

Metering Services

The meter operator bills the grid operator for installing, maintaining, and reading meters. Based on agreed rates from PRICAT.

Mehr-/Mindermengenabrechnung

Excess/Shortfall

Year-end reconciliation. Compares what the LF actually paid (based on estimates) against verified MSCONS data. Creates a correction invoice.

INVOIC: The Invoice Message

EDIFACT INVOIC contains: sender GLN, receiver GLN, invoice number, line items, amounts, VAT, and payment terms. It is the B2B equivalent of a paper invoice but structured for automated processing.

REMADV: Payment Confirmation

After payment, the payer sends REMADV (Remittance Advice) back. It references the original INVOIC number, confirms the amount paid, and may note any deductions or disputes. This closes the cycle.

Monthly Billing Cycle

Most B2B energy invoices are monthly. NBs bill LFs within 10 working days of month-end. LFs pay within 14 days. The MSB typically invoices the NB on the same cycle.

MSCONS accuracy determines invoice accuracy

Every euro in an INVOIC derives from a MSCONS reading. If the MSB sends a wrong reading, the NB bills the wrong amount, the LF pays the wrong amount, and a correction invoice (MMM) must be raised. This adds weeks of work. Correct MSCONS = correct billing first time.

End-to-End Financial Automation

INVOIC Generation & Dispatch

leitnetz generates compliant INVOIC messages from billing data, validates all required fields, and dispatches them automatically.

REMADV Ingestion

Incoming REMADV messages are correlated back to the originating INVOIC. Payment status updates automatically — no manual reconciliation.

Correction Invoice Handling

Mehr-/Mindermengenabrechnung (MMM) corrections are a dedicated process in leitnetz. Initiation, approval, and dispatch are all tracked in one place.
