The Great Separation is the practice of maintaining strictly independent financial ecosystems for your personal life and your business entity.

When this line is not clearly drawn, your books become commingled. Commingling can jeopardize limited liability protections, distort profitability, and turn a routine audit into a forensic nightmare.

Without this separation, a business owner cannot truly measure profit or protect personal assets from business risk. This is not optional if you want a defensible business.
