Family Office Software Guide for Offices Under $500M

Family offices under $500M occupy an awkward position in the software market. Enterprise wealth management platforms were built for banks and RIAs managing billions. The consumer-grade tools lack the reporting depth that principals expect. And the PE-focused platforms assume fund structures that most family offices don't have.

The result is that many family offices are running on a patchwork of tools that don't talk to each other — Addepar for consolidated reporting, a separate system for alternatives, Excel for private investments, and someone's Notion board for tracking everything the software can't handle. This guide covers what actually fits.

What Family Office Software Actually Needs to Do

Before evaluating platforms, the requirements for a family office differ meaningfully from a PE fund or an RIA:

• Multi-asset consolidation — public equities, fixed income, private equity, real estate, direct investments, and cash all in one view
• Principal reporting — reports that are readable by a principal who isn't a finance professional, not just an investment committee
• Tax basis and performance tracking — cost basis, unrealized gains, performance attribution across asset classes
• Document management — K-1s, brokerage statements, subscription agreements, estate documents
• Entity structure visibility — many families have 5–20 legal entities; the software needs to roll up properly

Addepar: The Market Leader

Addepar is the dominant platform for family offices and multi-family offices managing $100M+. It handles multi-asset consolidation genuinely well, including alternative investments and private equity holdings. The reporting layer is flexible and can be configured for principal-friendly outputs. Pricing is AUM-based and typically runs $25,000–$100,000+ per year for family offices in the $100M–$500M range.

The tradeoffs: implementation is a 3–6 month project and requires either internal technical resources or a third-party implementation partner (add $20K–$50K). The platform is powerful but complex — it rewards investment in configuration and punishes teams that deploy it without proper setup. For offices with a dedicated technology or operations person, Addepar pays off. For a two-person family office, it may be more platform than you can absorb.

Black Diamond and Orion

Black Diamond (now part of SS&C) and Orion are strong choices for family offices with heavier allocations to public markets. Both handle custodian data feeds, performance reporting, and client portals well. They're less capable on the alternatives and private investment side — if more than 30–40% of assets are in illiquid holdings, these platforms start showing their limitations. Pricing is similar to Addepar at scale but often more accessible for smaller offices.

The Lighter Stack: Quicken + Copper + Custom Reporting

For offices under $100M that can't justify $30K+/year in software, a practical alternative exists: use a custodian with good reporting APIs (Schwab, Fidelity), add a lightweight CRM for relationship tracking, and build a custom consolidated reporting template in Excel or Notion that pulls from structured data exports. It's not glamorous, but a well-maintained spreadsheet system with quarterly AI-generated commentary can serve a $50M family office better than a poorly-implemented Addepar installation.

Where AI Changes the Equation

The biggest opportunity for family offices isn't switching software platforms — it's adding an AI layer to what they already have. Specifically:

• Consolidated reporting narratives — AI can generate readable principal reports from structured data exports, turning quarterly numbers into the plain-English summaries principals actually read
• Tax document summarization — K-1s and alternative investment statements can be processed by AI to extract key figures for the family's tax team
• Document management — AI can categorize, tag, and summarize incoming documents, reducing the manual filing burden on small family office teams

For a $100M–$300M family office running on a reasonable but not enterprise-grade stack, adding an AI reporting layer on top of existing data exports is frequently the highest-ROI technology investment available — costing $500–$2,000 per month while saving 10–20 hours of staff time per reporting cycle.

The Decision Framework

AUM	Recommended Stack	Est. Annual Cost
Under $50M	Custodian reporting + Excel + AI layer	$5K–$15K
$50M–$150M	Black Diamond or Orion + AI layer	$20K–$50K
$150M–$500M	Addepar or Orion Enterprise	$40K–$120K
$500M+	Addepar + dedicated implementation	$100K+
