The Dallas business-process outsourcer and payment software provider BancTec Inc. said Thursday that it had sold its information technology service management unit to QualxServ LLC of Tewksbury, Mass.

The companies did not disclose the price.

The unit provides deployment and maintenance services for computer networks in North America and Europe.

BancTec said selling the unit would help it focus on its core operations, including outsourcing and payments.

QualxServ, which specializes in technology deployment and field delivered support service, until now concentrated its efforts in the continental United States and Canada.

J. Coley Clark, BancTec's chairman and chief executive, said in a press release that both companies will benefit from the transaction.

"QualxServ gains an outstanding team of professionals dedicated to delivering superior IT services, while BancTec achieves additional flexibility to sharpen its focus on BPO and related business solutions," Mr. Clark said.

Friedman, Billings, Ramsey & Co. Inc. served as BancTec's financial adviser for the divestiture, while Weil, Gotshal & Manges LLP provided legal counsel.

BancTec provides high-volume document and payment processing services and technology for clients in the financial services, health care, manufacturing, government, and utilities industries.
