Three wins in their last five games have propelled the Potters up to 12th place on 39 points and virtually secured Premier League survival with four games to spare.
Pulis has urged his side not to slip into holiday mode just yet, though, given Premier League prize money is still up for grabs.
Stoke are guaranteed £28.4million for staying in the top flight but will earn more the higher they finish.
"We have a responsibility to ourselves to keep things going," Pulis told the Sun.
"An extra place is worth £750,000 so moving up three or four places could mean £2m."
ShrewdPulis spent wisely in preparation for the club's Premier League debut this season, with shrewd signings such as Abdoulaye Faye, Danny Higginbottom and James Beattie playing crucial roles in their survival bid.
Despite anticipating a cash injection in the summer, the Stoke boss insists he must resist the temptation to splash the cash and focus on complementing his existing squad.
"It's still important we bring in the right people," he said. "It's about evolution. There's not going to be a revolution here.
"But we certainly need more quality and we need to improve in more areas. The important thing is to bring in the right characters."
