The Potters, who are now all but guaranteed to survive relegation, are in 14th place in the league ahead of this afternoon's action. However, Pulis insists that the club can still improve on their finish.
"We've done well, but it could get even better," he said.
"The important thing is that the team recognise that this is the business end of the season for us.
"We have to finish as high as possible in the table. It can be rewarding and help our plans moving forward."
Pulis's side travel to the Sports Direct Arena to face Newcastle United this afternoon.
