EEDIN (European EDI Network) is an alliance of European EDI providers that have interconnected their networks — meaning a customer of one provider can exchange documents with a partner of another provider, through a single contract and a single integration. REDOK is a founding member of EEDIN, which gives Croatian companies direct access to this European network.
This article explains what the EEDIN alliance means in practice, how interconnect between EDI networks actually works, which countries are covered and what value it brings to companies growing across the region or the EU.
What EEDIN actually is
EEDIN is a formal alliance of independent EDI providers across Europe, each dominant in their national market. Instead of every provider building country-by-country coverage in isolation, members have linked their networks and signed multilateral interconnect agreements — similar to how telecom operators arrange roaming.
Practical consequence: a Croatian REDOK customer can send an e-invoice to a partner in Slovenia (served by a Slovenian EEDIN member), Austria, Germany, Hungary, Czechia and so on. The invoice physically transits through the interconnect between REDOK and the partner provider in that country, while the customer holds only one contract and one SLA — with REDOK.
How it works technically
Interconnect between EDI networks runs on a shared protocol (AS4, AS2 or sFTP, depending on the pair) and a shared addressing system. When the REDOK gateway receives a document for a recipient in Slovenia, based on the recipient's tax ID and their primary network, REDOK routes it to the Slovenian EDI provider. The other provider then delivers the document to the recipient's ERP in their local format.
Validation happens on both sides: REDOK checks UBL/EDIFACT syntax and semantics against EN 16931 before sending; the Slovenian provider checks local specifics (e.g. mandatory attributes for the Slovenian Tax Authority) before the document enters the recipient's system.
Which countries are covered
- Croatia (REDOK) — the home network with 1,000+ customers and 40,000+ organisations exchanging via EDI.
- Slovenia — through the Slovenian EEDIN member, coverage of the main retail and FMCG chains.
- Austria — reach into Viennese and regional buyers; Peppol is dominant in the Austrian market.
- Germany — access to major German retail and industrial chains through the German EEDIN member.
- Hungary, Czechia, Slovakia, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia — broader regional reach.
- Through the Peppol network (REDOK is a certified Peppol Access Point), reach further extends into every EU country in Peppol — including the Nordics, Benelux, Italy and Spain.
Value for a Croatian company expanding abroad
Without EEDIN, a Croatian company expanding into the German market either has to sign a separate contract with a German EDI provider or ask its partners to accept its home (REDOK) format — which is in practice impossible. With EEDIN, expansion is an administrative minimum: REDOK extends which countries you cover, configures routing, and you start exchanging with German partners in the same technical environment as with domestic ones.
Concretely: one contract, one integration, one SLA, one point of contact — for coverage of the entire EU region under the EEDIN alliance or the Peppol network.
REDOK as a founder
As a founding member of EEDIN, REDOK has direct influence over interconnect rules, technical standards and the evolution of the alliance. That means Croatian customers gain access to the network without compromises in SLA, security or legal validity of the exchange.
