Case Study: How a North American Retailer Grew Garden-Tool Sales 32%

A regional home-improvement chain across the US Midwest approached us with a seasonal problem: garden tools sold in spring and died in fall, and the cordless line was a graveyard of mismatched batteries that confused both staff and shoppers.

We recommended consolidating the outdoor assortment on a single 20V platform that already powered their indoor cordless drills — hedge trimmer, grass shear, blower and a pole pruner, all sharing one pack.

Because the battery was already in customers' garages from the drill purchase, the garden SKUs became natural add-ons rather than standalone decisions. The chain merchandised them as a 'one-battery yard' end-cap.

Over three seasons the garden-tool category grew 32% year-over-year, and returns on cordless outdoor units fell as the standardized pack eliminated the most common complaint: 'it won't charge.'

The takeaway: outdoor and indoor cordless lines should share a platform. The battery you already sold is the best upsell engine you have.
