Top 10 Best Family Business Consulting Services of 2026

BDO’s family business advisory practice is built to support governance protocols work that spans shareholder dynamics, board composition decisions, and operating cadence for family forums. The delivery model usually starts with stakeholder interviews and fact-finding, then moves into documented recommendations that families can implement through governance artifacts and board processes. When ownership transitions are part of the mandate, the advisory commonly integrates liquidity planning and estate planning coordination so that family decisions align with business constraints.

A tradeoff is that advisory outcomes are shaped by the availability of family decision-makers for interviews and review cycles, which can slow execution when schedules and agendas are fragmented. BDO fits best when families need cross-functional advisory coordination and want outputs that carry into board-level decisions rather than remaining at a discussion level. A typical usage situation is a family preparing a leadership handoff while also refining voting and decision rights for day-to-day governance.

A key tradeoff is that results depend heavily on leadership participation during interviews and draft reviews, so families that want fully delegated work may feel bottlenecked. BanyanGlobal is best used when a family needs a structured path from internal conflict signals to governance decisions like who decides what and how those decisions get recorded and reviewed.

EY suits usage situations where the family wants one advisory partner to coordinate interdependent outputs, such as aligning ownership transition planning with compensation governance and board composition decisions.
