How to Choose Useful Expense Categories

Categories should be broad enough to reuse but specific enough to support decisions.
Good structure
Payroll or Salary
Rent
Utilities
Advertising and Marketing
Insurance
Office Supplies
Repairs and Maintenance
Professional Fees
Use the same category for the same kind of expense every time. The payee can vary while the category remains the same—for example, several employees may all use the Salary category.
