Overview
Centralized Showing Service (CSS) is no longer an independent product. Founded in 1996 by Kevin and Bob Faherty in Texas, CSS grew to serve 145,000 members across 70+ markets with 6 call centers before being acquired by ShowingTime on September 5, 2019. Following Zillow Group's acquisition of ShowingTime in 2021, CSS's live operator capabilities were fully absorbed into the ShowingTime+ product suite.
CSS's core differentiator -- live human operators who handle showing scheduling, contact sellers, and navigate complex appointment situations -- now lives on as part of ShowingTime's Appointment Center and 24/7 Live Appointment Specialists offering. The showings.com website redirects to ShowingTime's platform.
Agents who previously used CSS for live operator support should now look at ShowingTime's Appointment Center ($10-45/month through MLS partnerships) which incorporates those same call center capabilities. SentriLock's SentriKey Showing Service Pro (~$22/month) also offers a concierge call center as an alternative. CSS as a standalone brand is effectively deprecated, though the name may still be referenced by agents in markets where it was historically dominant.
