FOUNDATION SOURCE EXTENDS ENDOWMENT SUB-ACCOUNTING AS PART OF ITS INTEGRATED PHILTECH SUITE FOR PURPOSE-DRIVEN GIVING

Expanded functionality brings automated, scalable endowment accounting to more organizations through the Foundation Source enterprise platform

FAIRFIELD, Conn., Dec. 10, 2025 /PRNewswire/ -- Foundation Source, the leading provider of philanthropic solutions for donors, nonprofits, institutions, and the wealth advisors who serve them, today announced the broader availability of its Endowment Sub-Accounting capabilities to serve a wider range of organizations. Already in use by clients through its planned giving division, PG Calc, this expansion reflects the company's commitment to providing donors, nonprofits, and institutions with a complete, technology-enabled suite of giving solutions that enhance transparency and streamline administration.

This platform delivers efficient, accurate multilevel sub-accounting for organizations that pool multiple gifts for investment while maintaining detailed records for each fund or donor gift. By replacing manual spreadsheets with a purpose-built system, Foundation Source enables nonprofits and institutions to simplify fund tracking, improve audit readiness, and deliver detailed, custom reports to stakeholders.

"Philanthropy is evolving fast, and technology is the key to making it work better for everyone," said Joseph Mrak III, CEO of Foundation Source. "Endowment sub-accounting is a great example of how we're simplifying complexity – giving clients a more efficient, transparent way to manage philanthropic capital while staying true to donor intent and mission."

Foundation Source and PG Calc are expanding the reach of endowment sub-accounting at a time when nonprofits, community foundations, and complex giving programs are seeking greater financial transparency and stewardship tools. This capability integrates seamlessly into Foundation Source's broader PhilTech platform, which unites administration, compliance, and strategic advisory under one technology-enabled umbrella.

"With more nonprofits managing multiple restricted and endowed funds, accurate sub-accounting isn't a luxury – it's a necessity," added Gary Pforzheimer, President of Planned Giving at Foundation Source. "It delivers both collective investment strength and precise, fund-level transparency, ensuring accurate reporting, donor stewardship, and regulatory compliance."

Endowment sub-accounting supports a variety of philanthropic structures – including private foundations, donor-advised funds (DAFs), planned giving programs, and nonprofit endowments – by enabling:

• Transparent Donor Reporting: Clear tracking of each fund's income, expenses, and balance over time.
• Operational Efficiency: Unified investment pooling while maintaining detailed fund-level accounting.
• Compliance and Audit Readiness: Consistent allocation of earnings, losses, and fees in accordance with donor intent and accounting standards.
• Scalability: Designed to easily support organizations managing anywhere from a handful to thousands of funds.
• Comprehensive Functionality: Automated unitization of gifts and withdrawals; allocation of interest, dividends, fees, and gains/losses across sub-accounts; and customizable summary and detailed reports delivered via email, mail, or secure portal.

The addition of endowment sub-accounting reinforces Foundation Source's mission to simplify complexity, amplify impact, and make strategic philanthropy accessible to all – across donors, nonprofits, wealth advisors, and financial institutions managing philanthropic capital.
