Client Computing was established in 1995, and focused originally on message flow and EDI-messages to the power and textile industries. The business expanded to Sweden in 1998 by acquiring the EDI-part of Posten/SDS, and into Germany in 2006 through GLI GmbH.
In 2004 the company invested in Euronova AS, thereby accessing e-invoicing. Euronova later became a fully owned subsidiary named Client Computing Norway AS.
The Norwegian EDI and eInvoice activities were organised under Client Computing Utility AS and Client Computing Norway AS. In late 2010 Client Computing Utility AS was merged with Client Computing Norway AS. Client Computing Norway AS merged with Compello Software AS in 2012.
Compello Software was established in 1997 focusing on electronic invoice approval. This covers invoice scanning, interpretation (OCR), workflow and ERP integration. The company merged with Client Computing Europe ASA in 2011.
