How The Commonwealth Group (TCG) Member Star AC Supply Boosts Portal Adoption by 10x with Dill
HVAC
Arlington, TX
Advantive Distribution One
Star AC Supply is a wholesale distributor of heating and air conditioning equipment, replacement parts, and installation supplies servicing air conditioning contractors across North Texas. As a member of the buying group The Commonwealth Group (TCG), Star AC operates five locations in the Dallas–Fort Worth area—Arlington, Azle, Cleburne, Forney, and Granbury—as well as a new location in North Houston, serving the Greater Houston Area.
The Challenge
Before Dill, Star AC Supply was using a payments portal powered by Authorize.net, but it wasn’t delivering the experience their customers needed. The portal lacked basic features like invoice and statement visibility, and wasn’t integrated with their ERP, Advantive Distribution One. Customers had to manually enter invoice numbers, payment amounts, and their payment method every time they made a payment. To make things more complicated, credit card and bank ACH payments lived in separate workflows.
The friction was evident. Many customers struggled to use the portal, and some even used the clunky experience as a reason to delay payment. Leesa Gemeny, Director of Finance, heard it firsthand: "Customers would tell me they need a new payment portal."
The Solution
Star AC Supply adopted Dill to overhaul the online payment experience for their customers. With Dill’s integration with Advantive Distribution One, the new portal gives customers the ability to:
View current invoices and statements
Select which invoices to pay
Pay via bank ACH or credit card
Save their payment details for future use
Leesa noted, "The Dill portal is a lot more user friendly. Customers seem really happy."
The Results
The difference has been night and day:
Massive Uptick in Usage: Star AC Supply has seen 10x more customers using the Dill portal compared to their old system. The ease of use and transparency has driven adoption almost immediately.
Faster Collections: Customers who previously required 2–3 collection calls now pay proactively. "One day after the Dill portal rollout, some of these customers immediately paid," said Leesa.
Revenue Recovered: Star AC Supply has seen customers who were on credit hold begin paying through the Dill portal—and those accounts are now active and buying again.
Conclusion
With Dill, Star AC Supply has transformed its online payments experience from a liability into a competitive advantage. Their customers pay faster, collections are smoother, and the finance team spends less time chasing payments. For a growing distributor in a competitive market, Dill is helping Star AC Supply deliver a better customer experience and stronger cash flow.
"There are 10x more customers using the portal now than before," Leesa says. "Customers seem really happy."
