One of the more dangerous misunderstandings in running a med spa is treating profit and cash as the same thing. They aren't. Profit is an opinion shaped by accounting; cash is a fact you either have or don't — and the gap between them is exactly where growing, profitable practices get into trouble. A med spa can be profitable on paper and still be unable to make payroll, because the timing of money in and out, inventory, equipment, and growth can consume cash even as the business "makes money." Managing cash deliberately, not just chasing profit, is what keeps the doors open.
