Is EDI the same as e-invoicing?
Government e-invoicing schemes and EDI both move invoices electronically. They are not the same thing, and one does not replace the other.
Who is the counterparty?
That is the core difference:
- E-invoicing is an obligation towards the state. It uses a format the tax
authority defines, sent over its infrastructure. The purpose is tax oversight.
- EDI is an agreement with your trading partner. The parties decide the
format and content. The purpose is automating business processes.
One is a legal requirement, the other a commercial one.
Different scope
E-invoicing covers the invoice alone. EDI also carries the order, the order response, the despatch advice, the receiving advice and the remittance advice. The invoice is one link in the chain EDI concerns itself with.
A company using EDI is therefore not exempt from e-invoicing; it runs both.
Different formats
| E-invoicing | EDI (EDIFACT) | |
|---|---|---|
| Format | XML (UBL or similar) | EDIFACT (text) |
| Defined by | The tax authority | Trading partners |
| Compulsory | Above a legal threshold | When a partner requires it |
| Scope | The invoice only | The whole trade chain |
|---|
How it works in practice
The common arrangement: orders and shipments flow over EDI, while the invoice goes both to the trading partner as EDI and to the state in the mandated XML. The same commercial event is reported to two audiences in two formats.
The duplication looks wasteful but has a logic to it: the fields your partner needs and the fields the tax authority needs do not overlap.
The point not to confuse
Sending an EDI invoice does not discharge a legal e-invoicing obligation. And the reverse holds too: filing the legal e-invoice without sending your partner an EDI INVOIC leaves their system with nothing to trigger payment.
