Xchanging is a business process and technology services provider and integrator, owned by DXC Technology, providing business services to the commercial insurance industry. In outsourcing, Xchanging will typically take over a customer's business process, or back office function, and incorporate them into an existing platform.

Xchanging employs over 7,000 people worldwide. Xchanging offers IT outsourcing, infrastructure including network managed services, software products and application management. It also sells procurement services.

It was listed on the London Stock Exchange until it was acquired by CSC in May 2016. On 3 April 2017, DXC Technology announced that Xchanging was now part of the new company formed by the merger of CSC and HPE Enterprise Services.

Xchanging was founded in 1999, by David Andrews, a former partner in Andersen Consulting. Andrews came up with the idea at Andersen Consulting, to create joint ventures with multinational companies to outsource the processing of back-office transactions.

In 2000, Xchanging and BAE Systems created the first of these 'Enterprise Partnerships', for HR services (see also). A second followed soon after, again with BAE Systems, for indirect procurement. In 2012, Xchanging entered the US Indirect Procurement market through an agreement with U.S. based BAE Systems representing $800 million in spend to be addressed over 7 years.

Two years later, Xchanging and Lloyd's of London created two more 'Enterprise Partnerships', one for claims processing, and one for the London Insurance market's back office system; the latter including the IUA as a partner too. Further partnerships were signed with Deutsche Bank in 2004 (introducing Xchanging into the European financial market), Aon in 2006 (in broking services) and Allianz GI in 2007.

In 2007, Xchanging listed on the London Stock Exchange, entering the FTSE250.

In 2009, Xchanging acquired a 75% stake in Cambridge Solutions, another outsourcing business.
