Financial services technology company Fiserv Inc. has announced for the second time this month that it is selling another one of its business units. The company, based in Brookfield, Wisconsin, sold its remittance solutions assets, which include lockbox processing, to Deluxe Corp., a financial services company in Shoreview, Minnesota. 

Lockbox banking is a service for the receipt of payment from customers. Under the service, the payments made by customers are directed to a special post office box. The bank retrieves the payments and deposits the funds into the company's bank account. 

Deluxe will assume control of the Fiserv lockbox businesses operating in five locations, including the main facility in Chicago, and Fiserv will become a reseller of Deluxe lockbox processing. 

"We are confident that Deluxe is the right company to guide the Remittance Solutions business through its next chapter,” Byron Vielehr, senior group president of digital banking solutions at Fiserv, said in a news statement. "Our reseller arrangement is a testament to this, and a reflection of our shared commitment to help clients achieve best-in-class results."

Terms of the acquisition, which closed Dec. 16, were not disclosed.

Earlier this month, Fiserv announced it had entered into an agreement to sell 60% of its investment services business to an investment group led by private equity firm Motive Partners.
