Oxford manager Chris Wilder wants his players to build on a solid end to this season and embark on play-off quest next term.
Wilder signed a new contract last week but admitted he was disappointed after his side finished four points outside the top seven in ninth spot.
The U's found the net seven time without conceding in their final three games, including a convincing final-day 3-0 win over 10-man Accrington.
James Constable, Deane Smalley and Sean Rigg were on target while Lee Molyneux saw red for Stanley in the 89th minute.
"I am delighted we finished with a win for everyone who travelled to Accrington," said Wilder. "We kept it tight in the first half and then opened up after the break and scored three good goals.
"We have eight or nine out of contract and, even when we knew we weren't making the play-offs, the players have continued to be professional as they should be and play for personal pride and for the football club.
"We finished ninth and that's not where we want to be so it's about next season now."
Stanley boss Leam Richardson was disappointed with the result but proud of his players, who secured their League Two safety in the penultimate game of the campaign.
"We are disappointed as we wanted to finish with a win but I can't be too negative as the players have been fantastic," said the Stanley manager.
"Perhaps this was a game too far but I have got to give the players credit and it's nothing short of a minor miracle what they have done."
