Which tools show client accounts from several custodians in one view?
November 13, 2026
To see client accounts from several custodians in one view, you need a tool that connects to each of your custodians and groups the accounts into households. Two kinds of tools do this. Portfolio accounting systems such as Orion, Black Diamond and Addepar combine accounts for performance reporting and billing. Research and proposal tools such as Koyfin, Kwanti and Nitrogen combine them for analysis: exposure, risk, comparison with your models and proposals.
Which one fits depends on what you want to do with the combined view, which custodians you use and what you want to pay.
Tools that combine accounts from several custodians
| Tool | Best for | Custodians it connects to | Price per year |
|---|---|---|---|
| Koyfin | Research, model comparison and proposals across every household | Schwab, Fidelity, Altruist, Interactive Brokers, TradePMR; also Orion, Black Diamond and Addepar | $2,508 (Advisor Core, one custodian) or $3,588 (Advisor Pro, all connections) |
| Kwanti | Portfolio analytics and risk | Schwab, Fidelity, Altruist | $2,688 (one user), plus $100 for each extra Schwab master code or Fidelity G number after the first |
| Nitrogen | Risk scoring and proposals | Schwab, Altruist, Pershing, TradePMR, Interactive Brokers, Raymond James, LPL | $2,388 or $5,940 |
| Orion, Black Diamond, Addepar | Performance reporting, billing and trading | Most large US custodians | Quote on request |
Custodian lists come from each vendor’s pages and from Altruist’s and Schwab’s integration directories (checked November 2026).
How to choose
- Does it connect to all your custodians? Start with the custodians you use now and any you plan to add. A missing custodian means entering those accounts by hand.
- What do you want to do with the combined view? If you need actual returns, fee billing and trading, you need a portfolio accounting system. If you want to analyze households, compare them with your models and build proposals, a research tool is enough, and it costs less.
- Do you already have an accounting system? If Orion, Black Diamond or Addepar already combines your custodians, pick a research tool that connects to it, so households come in already organized.
- What does each extra custodian cost? Some vendors charge per custodian or per account number, so add up the cost for all your custodians.
Koyfin
Koyfin is an investment research platform for advisors. It brings client accounts from all your custodians into one view, where you can analyze each household and build proposals.
- Every account in one view. Client accounts sync from Schwab, Fidelity, Altruist, Interactive Brokers and TradePMR, and from Orion, Black Diamond and Addepar, grouped by household.
- Households kept up to date. Accounts sync every night, and households from Orion, Black Diamond and Altruist come in as they are.
- Each household compared with your model. See allocation, exposure, risk and the stocks held inside each fund against your firm’s model or any benchmark.
- Proposals from the same holdings. Build a proposal and a current-vs-proposed report without re-entering the account.
- Holdings without tickers still count. Bonds and private funds the feed can’t match become custom holdings with a name and asset class, so they stay in allocation and exposure.
Limits and pricing: Koyfin imports current holdings without transaction history, so actual returns and billing stay in your custodian or accounting system. Pershing isn’t connected. Advisor Core costs $2,508 a year with one custodian connection, and Advisor Pro costs $3,588 a year with all custodians plus Orion, Black Diamond and Addepar. New accounts get 7 days of full access.

Common questions about combining custodians
How many RIAs use more than one custodian?
About one in four RIAs (23.9%) holds client assets at two or more custodians, according to AdvizorPro’s 2026 custodian report built from Form ADV data. Schwab plus Fidelity is the most common pair (7.7% of RIAs), followed by Schwab plus Altruist (2.2%).
What’s the most affordable way to combine accounts from several custodians?
Research and proposal tools cost about $2,400 to $6,000 a year per user, while portfolio accounting systems are usually priced by quote based on assets or accounts. If you don’t need billing or actual returns, a research tool that connects to your custodians is the lower-cost option.
Do I need a separate tool if I already use Orion or Black Diamond?
Your accounting system already combines your custodians for reporting and billing. A research tool adds analysis on top: exposure, risk, model comparison and proposals. Connect it to your accounting system so the households come in already organized.
Is it safe to connect custodian data to a third-party tool?
Custodian data feeds are read-only and authorized by your firm. Ask each vendor for its SOC 2 report and release only the personal data fields it needs.
Does Koyfin connect to Pershing?
No. Accounts held at Pershing can be added by PDF statement upload on Advisor Pro, by CSV file or by hand.
