Decades in fenestration. Built by the people who've lived it.
preferp is built by Preference North America and PrefCo GmbH, two software companies with a combined history of more than 50 years serving window, door, and facade manufacturers. We didn't start as a software company that later found fenestration. We started in fenestration, and built the software our own industry needed.
