Goals from Adam Proudlock and substitute Tes Bramble saw Stockport claim victory against Boston.
The hosts took the lead midway through the first half when Proudlock's penalty was saved by David Galbraith before he netted at the second attempt.
Boston hit the woodwork through Mark Greaves, Drewe Broughton and Justin Richards as they battled back.
But the points were Stockport's when Bramble rose well to head home Michael Rose's well-flighted free-kick.
