Comprehensive portfolio aggregation has become an essential tool in modern wealth management. It serves as the foundation for multi-banking software, enabling wealth managers to gain a 360-degree view of all client assets. With the right digital tools, advisors can elevate the quality of their service and unlock the full earnings potential of their clients’ portfolios.
In this article, you’ll learn how fincite • cios is used as an efficient solution for financial data aggregation, giving wealth managers a complete and transparent view of client wealth.
Why Portfolio Aggregation Is Indispensable for Wealth Managers
Aggregating external portfolios is more than just a technical “nice to have” – it's a strategic enabler that transforms the entire wealth management process. But why is this so crucial in today’s financial landscape?
A 360-Degree View of Client Wealth
Wealth managers are expected to provide holistic advice while keeping an eye on increasingly fragmented financial data. Clients often maintain accounts across multiple banks, invest in illiquid assets, and work with various financial providers, including neobrokers. Without a central aggregation solution, important investment opportunities and earning potential can easily be overlooked.
Portfolio aggregation provides the foundation for multi-banking by consolidating all client portfolios into a single, unified interface. This not only ensures a comprehensive overview but also enables personalized and data-driven advisory strategies.
“Modern wealth managers rely on multi-banking because they know that having full visibility over a client’s Assets under View (AuV) is key to increasing their Assets under Management (AuM).”
– Marco Schüller, Product & Pre-Sales Manager at fincite
Maximizing Earnings Potential
Access to complete data across all accounts and portfolios allows wealth managers to tailor their investment recommendations based on the client’s total wealth – not just a portion of it. With multi-banking-capable wealth management software, these earning potentials can be identified and strategically leveraged, leading to sustainable returns.
Improving Efficiency and Saving Time
Automating the aggregation of financial data significantly reduces manual effort. fincite • cios offers seamless integration with banking systems and AISP providers, enabling the rapid and accurate consolidation of all relevant financial data. This frees up valuable time for wealth managers to focus on their core strength: personalized client advisory.
