About HPH

Our Mission

HPH’s mission is to provide quality content, master data management capabilities and an integrated transaction platform for the construction sub-contracting and material distribution industries.

Harrison Publishing House (HPH) is a content provider and software developer for the Plumbing/Mechanical industry in North America.

As the continent’s oldest independent information resource for the market, HPH has the industry knowledge, experience, and contacts to reliably deliver unparalleled quality content and software tools.

Throughout the years, Harrison has worked hard to become a trusted and reliable business information provider and partner. From industry-proven price books to electronic updates and online tools, HPH remains committed to providing the industry with its most complete source of information and management tools.

Today our HPH Item Codes, CINX software, and Pipeline services are helping bring reliable electronic transactions between contractors and distributors. As the trade participants seek to integrate their systems and migrate away from manual data entry workflows, HPH has the content, software, and services to make it happen.
