Most businesses that have been around a while have already tried the obvious fixes. More marketing. A new website. A harder push from the sales team. Some belt-tightening on expenses. Maybe even hired a consultant or two.
Those things can help. But if you've tried them and things in your business are still tighter than the revenue number suggests they ought to be, the problem probably isn't anything you've been trying to fix.
It's somewhere you haven't looked yet.
Profit Preservation is a short book for owners of established businesses. Companies with customers, revenue, employees, vendors, and a history of decisions that now shape how the operation runs.
It walks through the specific places where businesses lose money without realizing it. Not in sales or marketing, but in the structures, habits, contracts, and decisions that accumulated while you were busy running the operation.
The point isn't to fix everything. It's to know where to look, and which lever matters most given what you're actually trying to accomplish.
