Weiland Financial Group, which provides bank account analysis software to both corporate and financial institutions, has been acquired by Open Solutions, a vendor of software systems for financial institutions. The terms of the transaction were not disclosed.

Weiland will continue to offer its products on a stand-alone basis. Open Solutions, which was taken private in 2006 by Providence Equity Partners and the Carlyle Group, will integrate Weiland's products for banks with its own.

Open Solutions sells its bank solutions mostly to small and midsize banks and credit unions, while Weiland targets the large banks that dominate the cash management market and large corporations.
