The 24-year-old Scottish singer, who was the shock winner in last Saturday's final, is still waiting for a meeting with Simon Cowell about teaming up with Syco, reports the Daily Star.
"Simon spoke to me after the final but said he is very busy with American X Factor at the moment," said McDowall. "After the tour I will hopefully sit down with him and discuss what is going to happen."
McDowall won £100,000 and a slot at the Royal Variety, but reports suggest that runner-up 12-year-old Ronan Parke may go on to be the more successful act because of the buzz surrounding him in the industry.
Cowell championed boyband New Bounce and Parke during the competition, but after McDowall won, he claimed that he was already thinking about what he could do with the Scot.
Paul Potts and Susan Boyle, previous hit musical acts on the ITV1 show, have been snapped up with record deals within days.
A Syco rep said: "No decision's been made yet."
