Centralized Showing Service
showings.comCentralized Showing Service (CSS) was a live-operator showing platform acquired by ShowingTime in 2019 and is now fully integrated into the ShowingTime+ suite owned by Zillow Group.
The verdict
CSS is no longer an independent product. It was acquired by ShowingTime in 2019 and its live operator capabilities are now part of ShowingTime+. Agents seeking live operator showing support should subscribe to ShowingTime's Appointment Center through their MLS, or consider SentriLock's Pro tier concierge call center as an alternative.
01 — Overview
What Centralized Showing Service is, and isn't.
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.
