While buying into an advisory firm can be an incredible opportunity in the long run, there are also some very important caveats and potential problems to consider, in terms of both the financial terms of the succession deal, and also the more nuanced challenges of participating as one of several partners in a multi-owner firm.
In some cases, the problem is as “simple” as the fact that the business is not actually very profitable, especially once accounting for a reasonable salary to the existing owners of the practice (given that if/when they retire, a comparable salary must be paid for their replacement to do the same job duties!). Similarly, sometimes the problem is just that the valuation of the business is unrealistic, especially when it is valued based on a multiple of revenues but does not have very healthy profit margins to support that multiple.
On the other hand, some of the most challenging problems that crop up when buying into an advisory firm are more nuanced; for instance, if the timing of profit distributions won't line up to when the required loan payments are due, or when there are significant disagreements between the (new and existing) owners about how much to withdraw from the practice versus reinvest for the future. Often, it’s feasible to work through these conflicts – or even bring in an outside expert – but unfortunately, sometimes the only resolution is to raise the issues in advance, negotiate where possible, and if the challenges can't be resolved, to walk away from the deal.
