Choosing the right estate agency CRM platform is one of the most critical decisions a modern UK property business can make. The market has evolved rapidly, moving away from traditional, static record-keeping software toward highly flexible, automated platforms powered by enterprise architecture, Land Registry enrichment, and trainable AI.
