SME Invoice Finance and its subsidiaries has become wholly owned by Metro Bank which adds invoice and asset financing to the services the bank can offer.
Initially, SME will continue to trade in its own right as a specialist operation under the Metro Bank umbrella, and all SME customers will continue to be serviced directly.
Jason Oakley, Managing Director of Commercial Banking at Metro Bank, said: "As the entrepreneurs' bank, we've listened to what our customers want and are pleased to be able to make this announcement.
"The acquisition of SME is an excellent opportunity for us to provide extended financing options to our business customers, and make the business banking experience even more convenient."
Andy Preece, Regional Director of SME Invoice Finance in Sheffield, added that he was excited by the opportunities provided "under the Metro Bank umbrella".
