It has also enhanced reporting systems and improved its email templating system.
Alto has also integrated with SmartSearch, while further integrations will be enabled by ongoing investment in Alto’s application programme interface (API), which can be used by both customers and partners.
Andy Marshall, chief commercial officer at Zoopla, said: “When we launched our Vision earlier this year, we outlined our goal of combining our unique market position and data-led intelligence to put agents firmly in control, as well as a significant investment to improve our offering.
“From a software perspective, we’ve reached a milestone in this journey with Alto now delivering more value than ever before to our customers. We’re looking forward to building on this strong foundation and delivering even more innovation before the end of the year.”
