TAMP Portfolio Management Software: Model Shelves and Advisor Trade Requests
What TAMP portfolio management software is, and the software TAMPs use to present model shelves and take trade requests from advisors, comparing Vestmark, Envestnet, SMArtX, GeoWealth, Orion, proprietary platforms and Milemarker.
TAMPs present model shelves and take advisor trade requests with portfolio management platforms such as Vestmark, Envestnet, SMArtX, GeoWealth and Orion, or with a proprietary platform like AssetMark’s, and many add an advisor-facing layer on top. Milemarker gives a TAMP that layer: Investment Center shows advisors a branded shelf of the models they are approved to use, and Trade Center lets them submit model changes, rebalances and cash requests with validation, real-time status and a full audit trail, on top of the TAMP’s existing portfolio and trading systems.
What is TAMP portfolio management software?
A turnkey asset management program (TAMP) runs investment management on behalf of advisors: model construction, account management, rebalancing, trading, billing and reporting. TAMP portfolio management software is the platform that does that work. It usually covers:
- Model management. Building models and assigning them to accounts.
- Rebalancing and trading. Generating and routing trades, often through overlay or UMA management.
- Account administration. Onboarding, funding, billing and custodian connectivity.
- Advisor access. The shelf advisors pick from, proposals, and requests back to the TAMP.
- Reporting. Performance and statements for advisors and clients.
The advisor access piece is where many TAMPs feel the most pressure. Our guide to TAMP technology platforms covers the full stack.
How do TAMPs present model shelves to advisors?
Most TAMPs show advisors their shelf in one of three ways:
- Inside the core platform. Advisors log into the TAMP’s portfolio system and browse strategies there.
- In a proposal tool. Advisors pick models while building a client proposal.
- In a branded advisor portal. The TAMP publishes its shelf, fact sheets and commentary in its own portal, connected to the core platform.
The best shelves filter by what advisors actually ask: risk, fees, tax sensitivity, minimums, values and liquidity. They also show only the models that advisor is approved to use.
How do TAMPs take trade requests from advisors?
Advisors send TAMPs model changes, rebalances, cash raises, distributions, tax-loss harvesting requests and restrictions. Common ways:
- Email and phone. Still common, and the hardest to track and audit.
- Forms in the core platform. Structured, but often built for operations staff rather than advisors.
- A request workflow on top. Prefilled forms with validation, routing to the right team, status back to the advisor and an audit trail.
The test of any approach: can an advisor see whether the request went through without calling?
What software do TAMPs use?

Envestnet runs managed account and UMA programs with a large lineup of third-party models, plus advisor tools and MoneyGuide planning.
Best for: firms that want a broad managed account platform with many managers.
3. SMArtX Advisory Solutions
SMArtX provides TAMP and UMA technology with a model marketplace, automated rebalancing, tax management, cash management and billing, offered to advisors and to enterprises building their own programs.
Best for: firms that want modern UMA technology and a multi-manager marketplace.
4. GeoWealth
GeoWealth is a technology platform and TAMP for RIAs that combines portfolio management, back office and its own portfolio solutions, including a private model marketplace.
Best for: RIAs that want an integrated platform and outsourced implementation.
5. Orion
Orion combines portfolio accounting, the Eclipse rebalancer and trading, with Orion Portfolio Solutions as its TAMP and a model marketplace.
Best for: TAMPs and RIAs already on Orion’s platform.
6. Proprietary platforms (AssetMark-style)
Some large TAMPs, such as AssetMark, run their own proprietary advisor platform for proposals, account opening and managed accounts.
Best for: large TAMPs with the engineering budget to own the whole platform.
7. Milemarker Investment Center and Trade Center
Milemarker is a data and experience platform for TAMPs, RIAs, broker-dealers and aggregators. It connects custodians, portfolio systems, CRMs and planning tools into one normalized data layer on Snowflake, owned by the firm. Investment Center presents models, alternatives and insurance in one branded shelf with filters, comparison, due diligence documents and approval workflows. Trade Center lets advisors assign models, rebalance to model, and handle cash, with 100% allocation validation, trade timing and holiday checks, restriction enforcement, real-time status from submission to settlement and an audit trail by user, account and timestamp. It connects to Orion’s trading platform and supports a direct FIX connection, and advisors only see models they are approved to use.
Best for: TAMPs that want an advisor-friendly shelf and request flow on top of the portfolio and trading platform they already run.
How do the options compare?
| Vendor | Type | Best for | Works with existing stack? |
|---|---|---|---|
| Vestmark | Enterprise model and overlay platform | Large UMA programs | Yes, as a sponsor platform |
| Envestnet | Managed account platform | Broad multi-manager programs | Best inside Envestnet |
| SMArtX | TAMP and UMA technology | Modern UMA and marketplace | Yes, across supported custodians |
| GeoWealth | TAMP and technology platform | Integrated outsourced platform | Replaces several tools |
| Orion | Portfolio, rebalancing and TAMP | Firms on Orion | Best on Orion |
| Proprietary (AssetMark-style) | In-house platform | Large TAMPs | Built for one firm |
| Milemarker | Advisor shelf and trade requests on a data platform | Advisor experience on top of current systems | Yes, connects to existing portfolio and trading systems |
What are the common pitfalls?
- The shelf and the trading system disagree. If the shelf is a website and trades run elsewhere, advisors pick models that are no longer offered.
- Requests without status. Advisors who can’t see status call or email, which defeats the workflow.
- No validation up front. Allocations that don’t add to 100%, restricted tickers or holiday trade dates get rejected later instead of caught at submission.
- No audit trail. Every request should record who asked, for which account, and when.

Frequently asked questions
What is the difference between a TAMP and TAMP software?
A TAMP is the service that manages investments for advisors. TAMP software is the platform it runs on, which can be built in-house or licensed from vendors like Vestmark, SMArtX, GeoWealth, Envestnet or Orion.
Do TAMPs need to replace their portfolio platform to improve the advisor experience?
No. An advisor-facing shelf and request layer like Milemarker can sit on top of the existing portfolio and trading platform.
How can a TAMP make sure advisors only use approved models?
Entitle models by advisor, office or firm so each advisor sees only the models they are approved for. Milemarker’s Trade Center enforces this.
What should a TAMP trade request include?
The account, the requested change, the target model or amount, any restrictions, and an approval and status trail. Prefilling from the TAMP’s data reduces errors.
How long does it take to add Milemarker on top of a TAMP platform?
Typical Milemarker implementation is 2 to 12 weeks.
