Town produced a spirited display against high flying and big spending Greenwich Borough at Greatness Park.
One of only three Southern Counties East League games to beat a wet start to 2016, it attracted the biggest crowd of the season -136 - including chair Denise Richmond.
Town gave a debut to new recruit Tom Menditta from Corinthian at left back and returning midfielder Keiron McCann, back after a spell at Chatham, and worked hard from first whistle to last - but rued two great chances to claim at least a point.
Mike McKenna missed out in the first half, shooting straight at young Borough keeper Ben Bridle Card and then sub Michael Fahm screwed his effort wide eight minutes from time.
Borough claimed the points with Michael Power converting a 76th penalty to inflict Town's seventh home defeat of the season, after Mohammed Eisa tumbled in the box.
The visitors had loud claims for a similar award turned down early on, before Danny Young headed them in front after 18 minutes from a corner.
Borough created several chances afterwards but failed to trouble young Town keeper Tom Roberts as they shot wide of both posts and over the bar.
Town got back on terms just past the hour mark.
Fahm, just on as sub for Adam Marsh was hauled down on the edge of the box, earning ex-Bromley defender a booking.
McKenna's free-kick was blocked, the loose ball falling to Chris Edwards who rifled the ball inside the right hand post for his second Town goal against his old club.
Steve Camacho fired wide and then Fahm had his effort saved by Bridle-Card.
A minute later Borough were in front, courtesy of Power's penalty.
Tom Ripley headed wide in stoppage-time as referee Alex Stacchini added on eight minutes at the end.
