Private equity firm Marlin Equity Partners is buying International Business Systems AB (IBS) from Symphony Technology Group for an undisclosed amount.

Stockholm, Sweden-based IBS develops distribution resource-management software for the wholesale, distribution and manufacturing markets. The company provides resource planning, supply-chain management, warehouse management and sales and operations-planning services.

Symphony, a Palo Alto, California, private equity firm, has backed IBS since 2012. Other Symphony transactions include the purchase of McGraw Hill Construction, a construction data and analytics business, for $320 million, and acquisition of Aon plc's (NYSE: AON) global risk management business. The firm has more than $2 billion in capital under management.

Hermosa Beach, California-based Marlin is invested in other technology-related companies, including Tellabs, a networking services business that it paid $891 million for in 2013. Marlin also invests in health care, consumer, services and manufacturing businesses. The firm has about $3 billion in capital under management and closed a $400 million lower middle market-focused fund in April 2014.

Mooreland Partners advised IBS on the deal.
