Fund services buyer’s guide

February 02, 2026

Key takeaways

Effective back-office operations are critical for success, but challenges can drain resources.

Assessing your current fund administration operating model can reveal optimization opportunities.

Fund administration can evolve into an advantage that sets you apart instead of holding you back.

Is your operating model holding you back when it could be setting you apart?

Your back-office operations must run at peak performance—both to facilitate your growth plans and to satisfy current and prospective investors’ queries for real-time performance data, analytics and transparent reporting. Achieving such performance requires operating models fueled by best-in-class talent, which is not always available or affordable, along with the latest technologies, which typically introduce their own set of integration and maintenance challenges.

These realities are forcing managers to carefully reconsider how to optimize their current back-office operating model.

This guide can help you assess where your current fund administration operating model stands—and how it may need to change.

We designed this guide to help private fund chief financial officers make the best strategic choices for their fund’s operating model and service provider. Use it to compare different fund administration models and their benefits, explore strategic options and learn how RSM Fund Services+ can help turn fund administration into a competitive advantage.

Fund administration isn’t getting any easier

Challenges complicating fund administration

More stringent investor due diligence and increased reporting demands

91%

of asset management firms responding to our Private Funds CFO Insights 2025 survey note greater investor due diligence in the past year, placing increased demands on the back office

  • Expanding regulatory requirements
  • Growing tax complexity
    • Increased range and complexity of fund structure
    • Multiple reporting deadlines
    • The addition of K2 and K3 forms

  • Expanding digital transformation expectations
    • Improved data collection, tracking, analysis and presentation
    • Required investment in automation and advanced technology to produce quality real-time data at increasingly granular levels
    • Required significant financial and human capital resources and ongoing maintenance to keep pace

  • Widening talent gaps
    • Growing need for in-demand accounting and technical talent to handle critical back-office functions and prevent delays in fundraising efforts or responding to investor needs
    • Increased recruiting and retention challenges, heighted by limited career growth opportunities for administrative and technical professionals within most alternative asset management firms 

Choosing fund administration operating models and the growing need for third-party support

The three primary operating models for fund administration are insourcing, co-sourcing and outsourcing.

Insource

Own everything
Best for firms wanting full control and customization, with deep internal capabilities

Co-source

Own tech, outsource talent
Best for firms seeking shared oversight, efficiency and control over data/tech, plus scale

Outsource

Outsource everything
Best for firms wanting turnkey solutions, full segregation of duties, speed and simplicity

Given the complexities of modern fund administration and the hefty investment required to update legacy processes and keep pace with innovation, operating models are changing. While there is no correct answer to which operating model you should choose, it’s important to note that more alternative asset management firms are turning to external service providers for help. According to the Private Funds CFO Insights 2025 survey, 41% of firms say they will increase fund accounting outsourcing in the next 12 months.

Fund administration operating models—which one is right for your firm?

Ultimately, your firm’s specific circumstances and growth plans will dictate the best operating model for your strategic priorities. Remember that insourcing, co-sourcing and outsourcing form a spectrum, and many firms pivot from one approach to another over time. It’s also possible to incorporate elements of each approach to build a custom model that fully supports your strategy.

What to look for in a fund administrator

As more private equity and alternative asset managers look to third-party providers to help support fund administration, it’s important to remember that not all fund administrators are created equal. That’s why core capabilities should be only a starting point for selecting the best provider. Look for an organization that excels in the basics of fund administration, including fund accounting, investor reporting and tax compliance. Then, go beyond depth and breadth of services to consider how well that fund administrator is positioned to make the right decisions as fiduciaries for your fund today and in the future.

LPs are increasing their own due diligence efforts, so investors may want to evaluate and approve your fund administrator before investing. It’s therefore important to choose wisely.

Inside our engagements

Growing stakeholder confidence through enhanced reporting and data visualization

The client:

Our client is a private equity and real estate firm with more than $14 billion in assets under management (AUM), registered with the U.S. Securities and Exchange Commission, and with three Cayman Islands-domiciled funds.

The challenge:

With lean resources, the firm needed a fund administrator capable of prioritizing their clients and delivering consistent levels of services and support.

The impact:

By fully outsourcing fund administration to RSM, the firm gained trusted experience and a responsive team capable of handling everything from first-year audit support and cost segregation to anti-money laundering processes, investor onboarding, Form PF and Form ADV filings, as well as all required Cayman Islands Monetary Authority reporting. A custom investor portal and performance metrics dashboards helped strengthen communication and relationships with key stakeholders, setting up the firm for ongoing success. 

Creating space for strategic initiatives through comprehensive high-touch services

The client:

Our client is a U.S.-based private equity firm with $7.2 billion in AUM​ and multiple funds.​

The challenge:

The firm’s incumbent fund administrator was unable or unwilling to provide high-touch services and the subpar quality of their work resulted in multiple data errors, late reports and poorly kept books.

The impact:

The firm was already working with RSM for tax work, and the CFO asked RSM to take over fully outsourced fund administration and management oversight, including all investor servicing and investor communications. Additionally, RSM vetted all historical data, facilitated the firm’s transition to Allvue Systems and now oversees management of the technology and provides fully outsourced fund administration. Dramatic improvements in service and efficiency have allowed the firm’s leadership to turn their focus from administrative headaches to strategic initiatives. 

Creating a platform for increased cost efficiency and strategic acceleration through proactive advice

The client:

Our client is a private equity firm specializing in buyouts, with $1.3 billion in AUM.

The challenge:

Dissatisfied with its current fund administration, the firm was seeking experienced, proactive advice beyond just debits and credits along with advanced technology solutions and higher quality industry standard reporting.

The impact:

By delivering a range of advisory services along with staff augmentation, technology implementation, and accounting and audit support, RSM helped the firm improve reporting accuracy and overall financial management. Proactive advice on transactions, tax implications and other financial matters helped inform decisions, keeping the firm ahead of issues that could affect fund performance. 

Is it time to change the way you operate?

Your back office can be a source of support and a competitive advantage that propels your fund forward. If it feels more like a source of constant challenges or a drain on your resources, then it may be time to make a change.

Data quality and accuracy risks

  • Excessive data errors or discrepancies
  • CFO or audit team spending significant time reviewing data and vetting accuracy
  • Excessive effort spent on reviews, revisions and corrections

Reporting and compliance pressure

  • Late reports or missed deadlines (client‑imposed or regulatory)
  • Inability to quickly respond to investor or regulator requests for information
  • Unwanted tax implications

Capacity, talent and technology constraints

  • Insufficient resources (talent and/or technology) to support fund volume growth or more complex fund structures
    Drained resources: financial, human capital or otherwise

Service provider limitations and stakeholder concerns

  • Investor or LP concerns related to your current service providers
  • Current fund administrator unable to provide strategic insights or guidance to meet evolving needs
