Owners who get the strongest exits rarely start preparing when a buyer calls. They start about three years out, because the levers that raise a practice's value take time to move.
Three years out, the work is structural: clean up the books so earnings are verifiable, separate personal and practice expenses, and start tracking a normalized EBITDA. A buyer pays for what they can see and trust, and trust is built over multiple clean years.
Two years out, the focus shifts to the value drivers: broadening referral concentration, documenting systems so the practice runs less on you personally, and closing overhead gaps that a buyer would flag and discount.
One year out, it is about presentation and timing: a current valuation, a clear growth trend, tax planning for the sale year, and understanding how your state taxes the gain. This is when knowing your number before any buyer conversation pays off most.
Even if you never sell, this runway is just good practice management. A business that is sale-ready is a business that runs on clean numbers and documented systems, which is a better business to own in the meantime.
The mistake is compressing all of it into the ninety days after an offer. That is when problems get discovered at the worst possible time and priced against you.
