Bognor manager Jack Pearce is already planning for next season.
The Rocks need one more point to guarantee a place in the new Conference south division after a 1-0 win at Harrow Borough.
Guy Rutherford scored the winning goal just after half time to give Bognor their first victory in eight games.
Pearce is in no doubt his side will get the draw they need from their remaining three games to seal a top 13 finish.
He said: "We can still be caught, but it's unlikely because we only need a draw and even if we don't get it we have a superior goal difference from the chasing teams.
"The hard work starts now for next season as far as I'm concerned. We have shown we can beat anyone on our day and also that anyone can beat us when we don't perform, so there's a lot to sort out."
