Excellent article Musicphan. Except for outright "fictitious" data, "Seller's Discretionary Earnings" is the easy part...however the multiple of SDE is affected by many variables. Some of these variables, in my opinion, can not only make a huge difference in the selling price, but can potentially become the difference between maintaining the seller's proven success or failure of the business.
MaCowboy...does your team, including inherited workers, have the same or better skill set as the seller? How much of the seller's business is relationship sales? Will all clients transition over to the new ownership, or look at the transition as an excuse to shop around for a new supplier? This happens a lot in some businesses, such as in the insurance business. If the business is critically dependent upon a few key clients, then I would seek to obtain some sort of commitment from those clients. Use a worst case scenario...if key clients leave, what is left? Is there enough of a business to carry on and rebuild if that were to happen, or would you be shutting your doors. Successful businesses are most effective at minimizing risk, you shouldn't willingly step into a high risk situation if you are paying a premium to a seller...better to just start from scratch. If you can set a price contingent on retaining the current customer base, then try that approach. Hope this adds some to what the article mentions.
Best of luck in your endeavors MaCowboy
