E-invoice roaming


E-Invoicing roaming between Opus Capita, Omniva and Telema

According to the renewal of the Estonian Accounting Law all invoices to the public sector have to be sent as e-invoices by the beginning of 2017. Three Estonian biggest e-invoices operators Omniva, Opus Capita and Telema have replaced their local e-invoices’ networks with a roaming network. The new network gives more technical capability for companies to be in compliance with the legislative requirements.

The purpose of this roaming network is to widen e-invoices two-way traffic availability for all operators’ clients. Although every company can make direct connections with its business partners to exchange invoices electronically, there are too many accounting software or ERP’s that needed to be interfaced, and so it would be very costly. For reasonable fees operators provide the transportation, validation and conversion of e-documents. In addition operators maintain the infrastructure and also keep the systems up-to-date with constant innovations.

All clients that have chosen to work with one operator out of these three: Omniva, OpusCapita or Telema, can send and receive all their e-invoices through this roaming network. There is no need to make business agreements with all three operators. The client has to choose only one operator with the most satisfying solution. Sending or receiving invoices within this roaming network does not cost more than charges agreed with one operator.

The new technical need for Telema’s clients is that invoices in XML format should include company’s business registry code, country code, as well as the payment information block.

Prerequisites for sending e-invoices:
  • Agreement with one of the operators;
  • Accounting software should be interfaced with the operator’s software to send out e-invoices;
  • In case the client does not use accounting software the operators are offering web-based solutions for entering invoices and sending these in machine readable XML-format;

Prerequisites for receiving e-invoices:
  • Agreement with one of the operators;
  • Accounting software should be interfaced with the operator’s software to receive e-invoices directly to the accounting software, without human intervention;

Does this roaming system have any deficiencies? For the electronic communication to function, all the parties need to know who is technically able to benefit from paper-free invoices exchange. That’s why the State needs to initiate a central register of e-invoice users. Currently the register does not exist. Nevertheless the three operators have agreed to exchange the names of e-invoices users operatively.
