Every independent RIA faces a core investment-operations decision: assemble a best-of-breed portfolio management stack, leverage a turnkey asset management platform (TAMP), use a model marketplace with in-house trading, hire outsourced trading/rebalancing support, or (far less commonly) build bespoke tools. The right answer depends on your niche, your service model, and the business you want to run.
At XYPN, we help fee-only advisors design firms that fit their goals. This guide explains what turnkey asset management is, why advisors use it, what it costs, and how to decide whether a TAMP belongs in your stack, now or later.
What is a TAMP?
A turnkey asset management platform provides outsourced investment management and the technology to run it. At a minimum, a TAMP offers model portfolios, trading and rebalancing, performance reporting, billing, and custodial integrations. Many add tax-aware trading, SMA/UMA access, strategist marketplaces, sleeve accounting, proposal tools, and compliance-ready reporting.
Popular ways to categorize TAMPs include:
- By account structure (e.g., mutual fund/ETF wraps, SMAs, UMAs)
- By provider model (e.g., supermarket platforms with broad strategist menus, specialist providers focused on certain strategies or segments, curator platforms with pre-vetted lineups)
- By technology approach (e.g., product TAMPs with proprietary strategies vs. platform TAMPs that provide third-party access)
Beyond TAMPs, advisors increasingly use model marketplaces while retaining discretion, or hire outsourced trading/rebalancing providers, approaches that unbundle traditional TAMP services.
The goal is simple: reduce the time you spend on portfolio operations so you can spend more time in planning, advice, and client conversations.
Why fee-only RIAs use turnkey asset management
Advisors don't outsource investments because they "can't" manage money. They outsource to protect time and improve consistency.
- Capacity and focus: Kitces Research shows advisors generate more revenue when they spend more time in planning and client meetings instead of admin tasks (Kitces Research).
- Process and scale: Centralized trading, model drift controls, and automated cash management reduce errors and keep households aligned to policy.
- Breadth of solutions: A TAMP can open doors to SMAs, factor or ESG models, and tax-managed strategies that may be hard to build and maintain on your own.
- Client experience: Faster onboarding, clean performance reporting, and consistent rebalancing cycles build trust.
Adoption is nuanced. Surveys show roughly one-fifth of RIAs fully outsource portfolio management to TAMPs, while a much larger share use third-party model portfolios; providers like Envestnet, AssetMark, Orion Portfolio Solutions, Adhesion, and SMArtX appear frequently in advisor tech stacks (see the T3/Inside Information Advisor Tech Survey).
What turnkey asset management costs
TAMP pricing varies by provider, account size, and services. Fees are usually asset-based (basis points) and may include separate strategist fees. Some platforms offer flat or tiered per-account pricing at scale. Always review the total "all-in" cost to the client, including fund/ETF expenses.
Typical ranges you'll see
| Component | Common Range | Notes |
|---|---|---|
| Platform fee | 0.20%–0.60% | Trading, reporting, billing, and service vary widely by provider and service level |
| Strategist/model fee | 0.10%–1.00% | Varies by manager, vehicle (ETF strategist vs. SMA), and customization |
| Fund/ETF expenses | 0.03%–0.60%+ | Depends on underlying holdings |
| Transaction costs | Varies | Depends on the custodian, trading approach |
Some RIAs pass TAMP costs through to clients. Others bundle them into a single advisory fee. Pick the approach that best aligns with your value proposition and disclosures.
Build vs. buy: a simple decision framework
Outsourcing is not all-or-nothing. You can start with trading support while keeping models in-house, or outsource models while retaining client-specific tax management. Use this framework:
- Define your promise: What outcomes do clients hire you for? If your niche values advanced planning (tax, equity comp, retirement income), freeing 10+ hours/month for planning can outweigh the bps you pay a TAMP.
- Assess complexity: High-net-worth clients with concentrated stock, QSUs, or multi-account tax lots require robust tools. If you cannot deliver tax-aware rebalancing at scale, buy it.
- Map capacity: Count hours for research, trading, cash management, and reporting today. If you are the bottleneck, outsourcing may be cheaper than hiring.
- Run the math: Compare all-in TAMP cost to the cost of DIY software + staff—then add the value of time you recover for growth.
Break-even example (directional)
Assume $30M AUM, average TAMP platform + strategist = 0.30% (30 bps). Annual TAMP costs $90,000. A DIY setup (portfolio software, rebalancer, reporting) might cost $45,000–$90,000+ for software alone, plus 0.5–0.75 FTE for trading/ops ($45,000–$70,000 loaded). That can put DIY near $90,000–$160,000+. If a TAMP frees meaningful advisor time that you convert into two new planning clients per quarter at $3,000 initial + $250/month, the added revenue can help close the gap within a year.
The point is not that TAMPs are "cheaper." The point is whether they reallocate your time toward higher-value work and faster growth.
Your investment process is a business system. Build or buy the parts that move client outcomes forward.
Compliance and oversight still matter
Outsourcing does not outsource your fiduciary duty. You must perform due diligence, monitor performance to mandate, and oversee fees and conflicts. The SEC has emphasized vendor oversight under the Advisers Act, including a 2022 proposal focused on outsourcing practices (SEC Proposed Rule IA-6176) that was subsequently withdrawn in 2025; nonetheless, third-party vendor oversight remains an SEC priority.
Due diligence checklist
- Ownership, stability, and SOC reports: Who owns the platform? Review financial strength and security controls.
- Investment process: What drives model changes? How are strategists vetted and replaced?
- Trading and taxes: How do they handle tax-loss harvesting, lot-level trading, and multi-account households?
- Billing accuracy: Review samples. Confirm householding rules and breakpoints.
- Fee transparency: Understand platform, strategist, and fund costs. Validate ADV disclosures.
- Service SLAs: Ask about trade cutoffs, money movement, and response times.
- Custodian fit: Confirm supported custodians, account types, and paperless workflows.
- Data portability: Can you export models, transactions, and performance if you leave?
- Cybersecurity and BCP: Review incident response and business continuity plans.
Integration and client experience
A TAMP should fit your existing tech stack. Look for confirmed integrations—not just logos on a slide. Test real workflows end-to-end.
- CRM: Push/pull household data, tasks, and notes.
- Financial planning: Sync holdings, model targets, and cash flows for accurate plans.
- Client portal: Avoid duplicative logins. Decide which portal will serve as the "source of truth."
- Compliance archive: Capture proposals, IPS updates, and trade logs automatically.
Model marketplaces can be a middle ground. You keep your trading and billing tools, but tap third-party models for research and construction. This often reduces costs versus full-service TAMPs while boosting discipline.
Implementation playbook
Rolling out turnkey asset management requires a pilot and clear communication.
- Pick a segment: Start with new households or a clean, low-complexity cohort.
- Standardize models: Define risk tiers, tax sleeves, and cash rules before you migrate.
- Align fees and ADV: Decide on pass-through vs. bundled pricing. Update agreements and disclosures.
- Run parallel: Test data feeds, drift alerts, and billing for a full cycle before scaling.
- Create client messaging That Explains oversight, benefits, and costs in plain language.
- Measure KPIs: Track time saved, error rates, revenue per client, and net new households.
- Document oversight: Build a recurring review of strategist notes, performance vs. policy, and fee reasonableness.
- Plan an exit: Know how to unwind if needed. Confirm portability and timelines in the contract.
Common pitfalls to avoid
- Outsourcing strategy without accountability: You still own results. Stay engaged with due diligence and monitoring.
- Ignoring taxes: Ask how the platform handles tax budgets, gain deferral, and lot-level rules.
- Undercommunicating fees: Clients need to see the total cost. Keep it simple and transparent.
- Stack sprawl: Duplicating portals and reports confuses households. Simplify.

Turnkey asset management is a tool, not a strategy. Use it if it helps you deliver better planning, a smoother client experience, and a business that runs the way you want. If building in-house is your edge, invest there. If outsourcing frees you to serve more clients well, consider it.
