Leatherhead beat big-spending Billericay Town 3-1 to upset the odds in the FA Cup.
Jack Midson's brace and a late goal from Sammy Moore handed the Tanners victory in a first-round replay after Adam Cunnington had opened the scoring.
Billericay took the lead on the hour as Louis Theophanous slid through Jake Robinson, who held his run and squared for Cunnington to bundle home from close range.
Leatherhead's D'Sean Theobalds and Lee Minshull came close before a deserved equaliser arrived in the 68th minute. Pinball in the penalty area ended with Midson heading in at the far post.
Leatherhead took the lead in the 82nd minute as Rob Swaine picked up a second yellow card for a foul in the area and Midson made no mistake.
Moore had the last laugh - having rejected a move to Town earlier in the season - firing home a low effort in injury time to set up a second-round clash at Wycombe.
