Proval Vantage
The UK's standard development appraisal software for social housing
Our Products
Property development software built for every stage of a housing scheme
What does SDS product suite cover?
SDS's product suite covers every stage of a housing development scheme: valuing land, appraising viability, managing delivery, closing sales, and reporting on progress. Each tool works standalone or connects into the others, giving Registered Providers and Local Authorities one system instead of five disconnected ones.

“The support is great, you can phone with quick and silly questions and email when it’s not as urgent or out of hours. The support team are good at layman’s terms to make it easy for us to understand issues which can be quite techy.”
