INVOIC

Also: EDIFACT invoice · electronic invoice

INVOIC is the EDIFACT message for invoices and credit notes. It transmits invoice data in structured form so the recipient can check, match and process it automatically.

What it is

An INVOIC message typically contains the invoice number and date, the companies involved, and references to preceding transactions such as the order or the delivery. At line level it carries articles, quantities, prices and amounts, among other things. Added to that are totals, tax information and — where agreed — payment terms, early-payment discounts or further settlement details.

Those references are what make automated checking possible. The recipient can verify, for example, whether an invoiced quantity was ordered and delivered, or whether price and terms match the agreed data.

A related process variant is self-billing. Here the recipient of the goods or services produces the settlement based on the agreed and recorded performance. For the supplier the emphasis shifts from issuing the invoice to checking the settlement received.

In practice

With INVOIC the challenge often lies less in the transmission than in the commercial reconciliation. Rounding differences, differing price levels, partial deliveries, ancillary costs or divergent tax logic can all prevent an invoice from being processed automatically by the recipient.

For that reason it is not only the message fields that should be agreed in advance, but the validation rules too: which deviations are permissible? Which produce a warning, and which a block?

One point matters for German B2B e-invoicing: EDI procedures such as EDIFACT may continue to be used, provided the statutory conditions are met. What counts is that the agreed structured format makes the information required for VAT purposes correctly and completely extractable, and that the legal requirements are satisfied. The technical implementation and the tax assessment should be considered separately.

Our task in such projects is the technical and procedural integration: that the agreed content is generated correctly, transmitted, logged and processed traceably in the target system. Individual tax questions belong with your tax advisers or accounting department.

When it affects you

INVOIC is often introduced together with other EDI messages, but it need not be the last step in a fixed sequence. What matters is that the references between order, delivery and settlement are held consistently in your own system.

With self-billing it is particularly important that incoming settlements can be checked automatically against your own performance and delivery data. A trading partner's implementation guideline and one real sample invoice usually show quickly which data and validation rules the connection will need.
