SumIt, a powerful, multi-entity general ledger and accounting platform built by family offices for family offices, announces integrations with Bill for streamlined payments and Addepar for enhanced investment tracking. These additions provide family offices and high-net-worth individuals with a more holistic, user-friendly solution for increasingly complex financial operations.

In 2024, Deloitte estimated there were approximately 8,030 family offices worldwide—a 31% increase since 2019—with projections reaching 10,720 by 2030. This swift expansion underscores the rising need for robust, intuitive accounting software tailored to family offices. SumIt addresses this demand by enabling users to manage multiple entities, record journal entries, and generate consolidated reports with just a few clicks. The platform's intuitive interface provides a clear visualization of trusts, LLCs, and other structures enhanced by AI-driven transaction categorization.

Many family office accounting platforms promised to unify family office accounting and workflows, but, in practice, they were too complicated for many. On the other end of the spectrum, overly simplistic solutions lacked crucial features needed by family offices. Founded initially to fill the gap between these extremes, SumIt has quickly become a trusted partner to some of the nation's most prominent single and multi-family offices and CPA firms.

Integrating Bill's payment and financial operations platform, SumIt allows clients to schedule, track, and reconcile payments in one unified space. Addepar's investment-focused capabilities make incorporating and analyzing portfolio data easier, creating a comprehensive 360-degree view of financial activities.

"Integrating Bill and Addepar with SumIt was the first step in our mission to help family offices manage their increasingly complex operations more simply," said Alexandre Lin, Founder and CEO of SumIt. "Whether paying bills, tracking investments, or creating reports, SumIt consolidates everything into one secure, intuitive platform—enabling family offices to do more with less." Lin continued, "2025 will be even more exciting as we refine our custom reporting capabilities, build partnership accounting modules, more AI functionalities, and deeper integrations within the ecosystem".

SumIt is entirely SOC 2 Type 2 certified, demonstrating adherence to the highest data protection standards. The company is also a close partner with the Family Office Exchange and leverages a 30+ member board of advisors who work in the space, ensuring its roadmap is shaped by real-world family office needs.
