Withum, a top 25 accounting firm, has partnered with technology company Aiwyn to launch Aiwyn Experience, a unified client portal designed to streamline service delivery and client engagement for professional services firms. The platform consolidates traditionally disconnected client-facing tools into a single system, handling request intake, document exchange, deliverables and payment. Withum collaborated with Aiwyn to develop the custom-branded solution, which integrates seamlessly with existing technology through modular architecture and open APIs. According to Aiwyn research, 76% of accounting firms rate client experience as their top priority. The platform aims to address the gap between client expectations and disparate tools firms traditionally use, reducing manual coordination and allowing teams to focus on higher-value work whilst supporting scalable growth.
