Two leading e-commerce software providers have been acquired by the same investment firm.

Vista Equity Partners has acquired e-commerce platform MarketLive and e-commerce order management software provider Shopatron for an undisclosed price. Top500Guide.com data shows that MarketLive is the e-commerce platform for 14 retailers in the  Internet Retailer 2015 Top 1000, while Shopatron provides order management software to Modell’s Sporting Goods, No. 728 in the Internet Retailer 2015 Second 500.

“By integrating best-of-breed commerce solutions and combining industry-leading expertise, MarketLive and Shopatron are incredibly well-positioned to bring a highly adaptive omnichannel commerce platform to the rapidly expanding retail market,” Vista Equity Partners CEO Robert Smith said.

The acquisition is expected to be completed by the end of the year.
