Top 10 Reasons Wealth Management Firms Should Use Financial Data Aggregation

Data is the lifeblood of personalized advice, portfolio optimization, and client trust. Yet, many advisors still struggle when financial data has to be pulled from multiple systems. It creates fragmented account views, manual data entry, and limited visibility into held-away assets. That’s where financial account aggregators that enable account aggregation and integrate into the wealth technology landscape become critical. 

Account and data aggregation are now core capabilities in modern financial institutions, wealth management firms, and wealth technology platforms to help consolidate financial data from multiple sources into one view. 

Here are the top 10 reasons wealth management firms and wealthtechs should embrace financial account aggregation and data aggregation tools. 

Wealth managers need a 360-degree view of client assets—not just those under direct management. A data aggregator specializing in investment data enables advisors to access both advisor-permissioned custodial data and client-permissioned held-away accounts, consolidating everything from brokerage accounts to annuities and trusts through secure connections. This holistic view is foundational for accurate planning, reporting, and advice. With account aggregation, advisors and their customers can see a complete financial account picture, which supports better decisions. 

Accurate performance reporting requires granular, transaction-level data. ByAllAccounts delivers reconciliation-ready data, including open and closed tax lots, mapped to Morningstar security IDs. This allows firms to calculate returns with precision, reduce manual intervention in the reporting process, and meet client expectations for transparency.  

Aggregated data reveals spending habits, cash flows, and asset allocations—enabling advisors to tailor financial plans to each client’s unique goals. Specialized aggregators can enrich financial data with investment attributes like region, sector exposure, and style boxes, supporting deeper portfolio analysis, more informed proposals, and a clearer customer experience. 

Held-away accounts often represent significant wealth. Financial data aggregators allow clients to securely link these accounts, giving advisors visibility into assets that may otherwise remain hidden. This unlocks opportunities to grow Assets Under Advisement (AUA) and eventually bring more assets under management.  

Managing multiple custodial relationships across institutions is complex and time-consuming, slowing the advisor onboarding process. ByAllAccounts offers access to custodial data sources through a single connection. This reduces onboarding friction, simplifies data workflows, and allows advisors to scale their practices without increasing operational overhead.

Regulatory compliance is non-negotiable. Aggregated data helps firms monitor trade activity, identify potential conflicts of interest, and ensure adherence to fiduciary standards while reducing risks. Specialized data aggregators support compliance workflows with structured, auditable data across platforms.  

Clients expect seamless digital experiences and personalized advice. Account aggregation empowers advisors to deliver both—with real-time insights, goal tracking, and financial wellness tools that strengthen relationships and build trust.  

Aggregated data isn’t just about visibility—it’s about insight. Advisors can identify trends, uncover opportunities, and deliver proactive financial advice that drives better client outcomes. Aggregated data enables premium analytics that help firms increase wallet share and deepen client engagement.

Whether you're an independent advisor, a broker-dealer, or a wealthtech innovator, aggregation tools offer the clarity, efficiency, and insight needed to thrive in modern wealth management.
