RIA Custodian Selection: Schwab vs. Fidelity vs. Altruist for Independent Advisors
Your custodian is the operational backbone of your RIA — the platform where client assets are held, trades are executed, fees are debited, and performance reports are generated. Choosing the wrong custodian creates friction for clients, headaches for your operations, and potentially impedes your ability to use the portfolio management software you prefer. This guide compares the four major custodial options for independent RIAs and provides a decision framework based on AUM size, client type, and technology preferences.

The Quick Answer
For most new independent RIAs, the choice is between Schwab Advisor Services, Fidelity Institutional Wealth Services, and Altruist. Schwab and Fidelity are the two largest custodians by RIA AUM and offer the broadest integration ecosystem and most established service teams — choose between them based on service responsiveness in your region and your portfolio management software's preferred integration. Altruist is the right choice if you are starting small (under $30M AUM), want integrated billing and reporting without paying for a separate platform, and value a modern digital client experience. Pershing is best reserved for practices above $100M with complex alternative investment needs. Most large RIAs use multiple custodians to accommodate legacy client accounts and provide competitive redundancy.
Schwab Advisor Services: Strengths and Considerations
Schwab Advisor Services (schwab.com/advisor-services) is the custodian of choice for approximately 7,500 RIAs managing over $1 trillion in advised assets as of 2026. Schwab's platform, Schwab Advisor Center, provides a comprehensive set of trading, reporting, and client management tools. Key strengths: (1) Deep integration with virtually every major RIA software platform — Orion, Black Diamond, Tamarac, eMoney, MoneyGuidePro, RightCapital, and Redtail CRM all have native Schwab integrations; (2) No formal AUM minimum for advisor accounts, though dedicated relationship management typically begins at $25M–$50M; (3) The iRebal rebalancing platform is offered free to Schwab advisors — a significant value for practices that would otherwise pay $5,000–$15,000/year for standalone rebalancing software; (4) Broad product access including mutual funds, ETFs, individual securities, fixed income, options, and alternative investments; (5) Schwab's TD Ameritrade integration (completed 2023) expanded the advisor network and added the thinkorswim trading platform for more active advisors. Considerations: Schwab's service model is tiered by AUM, and smaller RIAs may experience slower service response times; some advisors report that the Schwab Advisor Center interface, while functional, feels dated compared to Altruist's modern design.
Fidelity Institutional Wealth Services: Strengths and Considerations
Fidelity Institutional (fidelity.com/institutional) serves approximately 3,500 RIAs and is widely regarded as having the strongest dedicated service model among the major custodians. Key strengths: (1) WealthCentral advisor platform provides integrated portfolio management, account management, trading, and reporting tools; (2) Fidelity's dedicated RIA service teams are consistently rated highly for responsiveness — particularly valuable when clients have service issues that need rapid resolution; (3) Fidelity's breadth of institutional research, model portfolios, and third-party asset manager relationships provides resources that smaller RIAs can leverage without having their own research capability; (4) Strong fixed income trading platform and bond ladder tools, advantageous for RIAs serving income-focused retiree clients; (5) Competitive integration ecosystem comparable to Schwab, with native connections to all major RIA software platforms. Considerations: Some advisors report that Fidelity's new account opening process is slightly more paper-intensive than Schwab's; Fidelity has not built a native rebalancing tool equivalent to iRebal, requiring third-party rebalancing software.
Altruist: The Modern Custodian Built for RIAs
Altruist (altruist.com) launched in 2018 with a specific mission: eliminate the cost and complexity of running an independent RIA. Key strengths: (1) No AUM minimum and no per-account fees — making it the most accessible custodian for new and smaller RIAs; (2) Commission-free trading on stocks, ETFs, and mutual funds through their platform; (3) Integrated billing — Altruist calculates AUM fees and processes deductions automatically, eliminating the need for a separate billing module in portfolio management software; (4) Built-in performance reporting and client portal that is modern, mobile-responsive, and client-facing — comparable to what many RIAs pay separately for through Orion or Black Diamond; (5) Fully digital account opening with no paper forms required for most account types; (6) API-first architecture that integrates with major RIA software platforms including Orion, Redtail, and most planning tools. Considerations: Altruist's investment product breadth (especially for alternative investments and certain fixed income products) is narrower than Schwab or Fidelity; some advisors are cautious about the company's shorter operating history (founded 2018 vs. Schwab's decades-long track record); third-party software integrations, while growing, are not as comprehensive as the Schwab or Fidelity ecosystem.
Multi-Custodian Strategy: When and Why
Many established RIAs maintain relationships with two custodians — typically Schwab plus Fidelity, or Schwab plus Altruist. The reasons: (1) Client preference — some clients have existing accounts at a specific custodian and prefer to stay; forcing a transfer is a client retention risk; (2) Account type coverage gaps — if your primary custodian doesn't support a specific account type (certain 529 plans, ABLE accounts, or specialized trust structures), a secondary custodian fills the gap; (3) Service redundancy — having a backup custodian relationship means you can move assets if your primary custodian has service issues, changes fee structures, or is acquired; (4) Competitive leverage — custodians provide better service and negotiate on technology costs for advisors who could move assets to a competitor. For a new RIA launching with under $30M AUM, starting with one custodian (Altruist or Schwab) and adding a second at $50M–$75M is the most operationally manageable approach. Running two custodians adds complexity to billing, reporting aggregation, and reconciliation.
Evaluating Custodian Technology Integration With Your RIA Stack
Before finalizing your custodian, map your planned technology stack and verify native integration depth with each platform. The most important integrations for a solo RIA are: portfolio management software (Orion, Black Diamond, or Altruist built-in) for performance reporting and billing; financial planning software (RightCapital, eMoney, MoneyGuidePro) for account data import; and CRM (Redtail, Salesforce FSC) for client account data synchronization. Schwab and Fidelity have the deepest third-party integration ecosystems — virtually every major RIA software platform has a certified data feed from both. Altruist's integration library is growing but narrower as of 2026. Check each software vendor's integration page directly: Orion's 'Integrations' page and Redtail's 'Partners' page both list every custodian they connect to and the data elements synchronized. A misaligned custodian-software combination forces manual data entry that consumes hours of staff time each week.
Transition Mechanics: How to Move Client Accounts to Your New Custodian
Transitioning client accounts from your former firm's custodian to your new RIA custodian is the most operationally intensive part of the breakaway process. The standard method is an ACAT (Automated Customer Account Transfer) — an industry-standard electronic transfer between custodians that moves assets in-kind (without selling) in 5–7 business days. Your new custodian's transition team will provide ACAT initiation forms and manage the process. Important considerations: (1) Employer-sponsored retirement accounts (401(k)s) cannot be ACAT transferred — the client must initiate a rollover to an IRA; (2) Proprietary products at your former firm (house funds, wrap programs) may not be transferable and must be liquidated first; (3) Transfer timing — coordinate with your custodian's transition team to minimize the period clients are 'in transit' without access to their accounts; (4) During the transition period, continue using your former firm's tools to monitor client portfolios until the transfer is complete. Both Schwab and Fidelity have dedicated transition teams that provide concierge support for breakaway advisors, which is a meaningful differentiator from Altruist's more self-service model for large transitions.

FREQUENTLY ASKED QUESTIONS
Does Schwab Advisor Services have a minimum AUM requirement for new RIAs?
Schwab Advisor Services does not publish a hard AUM minimum for new RIA accounts, but practical service levels scale with AUM. New RIAs under $25M typically receive self-service support through Schwab's online advisor portal and phone support queues rather than a dedicated relationship manager. Dedicated relationship management generally begins at $25M–$50M in AUM. Altruist imposes no minimum and is generally more accommodating of RIAs in their early growth phase.
Can I use both Schwab and Altruist as custodians for different clients?
Yes — many RIAs use multiple custodians. The primary operational consideration is that your portfolio management software must support data feeds from both custodians for reporting and billing purposes. Orion, Black Diamond, and most major platforms support multiple custodian feeds simultaneously. Altruist also provides its own integrated reporting, so some advisors use Altruist's built-in tools for Altruist-held accounts and a separate platform (like Orion) for Schwab or Fidelity accounts.
How long does it take to transition client accounts to a new RIA custodian?
Standard ACAT transfers take 5–7 business days once initiated, but the full transition process — from client authorization through account establishment and first trade — typically runs 4–8 weeks for an advisor transitioning 30–100 households. Factors that extend the timeline include proprietary product liquidations, retirement account rollovers (which require separate IRA paperwork), and estates or trust accounts with complex documentation requirements. Schwab and Fidelity both offer dedicated breakaway transition teams that can compress this timeline with proactive coordination.
Is Altruist safe for client assets?
Client assets held at Altruist are protected by SIPC coverage up to $500,000 per account (including $250,000 in cash coverage), the same as Schwab and Fidelity. Altruist is a registered broker-dealer and FINRA member. The primary risk consideration is operational — Altruist is a younger company (founded 2018) with less operating history than Schwab (founded 1971) or Fidelity (founded 1946). For most advisors, SIPC coverage and FINRA membership provide adequate protection; advisors who want maximum institutional stability may prefer Schwab or Fidelity for larger client accounts.
