Case Study: a US-based marine supplies company increases seasonal sales by 104% with Quartile

US-based Marine Supplies Company increased seasonal sales by 104% with Quartile

A US-based marine supplies company specializing in boat winterization products faced the challenge of inconsistent Buy Box ownership on Amazon, which restricted its ability to capture demand and scale advertising during its critical three-month peak season. The hybrid nature of its catalog, containing both private-label and reseller products, further complicated performance measurement. Vendor Quartile was engaged to address these operational and advertising constraints.

Quartile implemented a solution that prioritized Buy Box competitiveness through pricing and fulfillment improvements, then restructured advertising campaigns around Sponsored Products. The core strategy involved a seasonal acceleration plan that aggressively scaled investment ahead of and during the peak demand window. As a result, Quartile helped the brand achieve a 104% increase in total sales and a 206% increase in ad-attributed sales during the peak season, effectively doubling its crucial seasonal revenue.
