Morningstar ByAllAccounts review
A broad aggregation layer for wealth platforms needing institutional investment data.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Morningstar ByAllAccounts is a financial account aggregation platform for wealth-management firms, advisors, fintechs and data providers. Its Connect Suite combines Account Linking and Account Summary web components with REST API endpoints for investor registration, positions and transactions, plus a DataConnect XML API for authentication and data extraction. The service handles user-permissioned account, position, transaction, security, price and tax-lot data, while also supporting advisor book-of-business aggregation.
Pricing uses a contact-sales model, with discussions handled through the sales process. The platform is delivered through web and API access and connects with more than 15,000 financial data sources, including 1,200 institutional sources and 70-plus wealthtech platforms. Custodial feeds, data-distribution integrations and test financial institutions extend its fit for firms building or validating integration workflows. These capabilities suit mid-market and enterprise teams that need a broad connectivity layer across multiple institutions.
The standout strength is breadth: ByAllAccounts combines account linking, account management, institutional aggregation and tax-lot data in one service. Test financial institutions can support integration development and data testing, while the Account Linking component is designed to connect institutions and resolve connection issues. Its focus is data aggregation rather than transaction execution or account origination. Organizations that need trading orders or account opening should pair it with another system or choose a product centered on those functions; firms focused on consolidated investment data and wealth-platform connectivity are the natural fit.
