Bromley came from behind to draw 1-1 at Oldham as they finished the regular season in seventh place in the National League.
Joe Nuttall opened the scoring a minute before the break after rounding Bromley goalkeeper Reice Charles-Cook and slotting home.
But the visitors levelled in the 79th minute through James Vennings’ powerful finish into the bottom corner.
Charles-Cook came to Bromley’s rescue in the 80th minute as he pushed Mark Shelton’s effort wide.
Bromley, who were already guaranteed a place in the play-off eliminators, will now face Woking on Wednesday, with a semi-final spot on the line.
