This definitive resource for accounting principals specifically for spas was created by the ISPA Foundation in a collaborative effort with: author Raymond S. Schmidgall Ph.D., CPA, Professor, Michigan State University; the Educational Institute of the American Hotel & Lodging Association; and Hospitality Financial & Technology Professionals. This book provides a recommended standardized financial reporting system that will allow spa professionals to measure, compare and report on the financial health of their business. Though uniform, the flexibility of the system allows both large and small spa operations to use the same reporting system.
