The new London site at Broken Wharf, near Blackfriars, is already trading for business and is currently targeting contracted clients.
It will focus on office print and will be officially launched on 12 June.
According to Cats Solutions managing director Greg Smith (pictured), the hub secured six contracts "before the doors even opened".
"Manchester is definitely next," he said. "We hope the operation will be open by Christmas or next spring at the latest. We want to find a location close to where the big boys are."
Smith added that he is currently looking at sites that are similar to the London operation. The aim is to duplicate the layout as well as installing the same kit. The London site has a raft of Xerox equipment.
Cats is also set to open additional sites in Glasgow, Birmingham, Cardiff and also Dublin.
Cats Swindon headquarters will support London for larger, more complex, jobs.
