Johnstone Supply subsidiary includes DSPro distribution software.

Johnstone Supply Inc. and DDI System, LLC have signed a letter of intent on the transfer of Johnstone Supply’s Data Services subsidiary including their DSPro distribution software to DDI System, LLC creating a new DDI-DSPro division.

“DDI has over 30 years of experience in the HVAC and PHCP industries making our inform software and company culture the perfect fit for Johnstone Member wholesalers. DDI’s inform software will seamlessly integrate with Johnstone Corporate and deliver a comprehensive and streamlined solution to run their entire business operations,” says Adam Waller, President and Founder of DDI System.

With over 650 clients and 8,000 users in North America, DDI System has the strength and stability to support the Johnstone Supply members as a long-term technology partner. DDI’s HVAC and PHCP feature set continuously grows as technology evolves. Their customer care model was a deciding factor in Johnstone Supply’s final decision of moving forward with DDI. Proven transition methods, online and onsite training, plus online customer portal access ensures outstanding customer support for the Johnstone community.

DDI welcomes the highly regarded Johnstone Data Services team to their strong set of industry experts, further building on DDI’s strength in the west. The acquisition will be finalized within the next couple months.
