Case Study: Design Air achieves 38% webstore revenue growth and 25% fewer inbound calls with Billtrust eCommerce

HVAC distributor sees steady increase in online sales and revenue through Billtrust eCommerce webstore

Design Air, a 98‑year‑old HVAC design and distribution company with eight Midwest locations, struggled with an unreliable eCommerce webstore that suffered frequent downtime, poor performance and incomplete product information—forcing inside sales and support teams to spend excessive time resolving routine issues by phone. To modernize their online presence, Design Air selected Billtrust and its eCommerce solution to provide a supported, functional webstore.

Billtrust built a stable, scalable webstore with enriched SKUs, intelligent catalog search and filtering, Prophet 21 integration and improved site performance, giving customers 24/7 access to documentation, pricing and inventory. The Billtrust solution delivered measurable impact: a 38% increase in revenue share from the webstore, a 25% decrease in inbound calls, and steady month‑over‑month growth in online sales within the first three months.
