Certification
RESO certifies systems to ensure they comply with real estate data standards. A RESO certification is a badge of honor for a system which technology developers and brokerages can rely upon to be interoperable with other tools.
The goal of certification is to bring a technology experience to real estate that consumers and professionals expect. Consumers demand a smartphone experience where apps, servers, and any other systems can talk to one another and operate seamlessly together. Standards provide that common language.
Certification Quick Facts
