What to Focus On
- Unit of Sale is a management tool to standardize measurement in multi-product businesses.
- For grocery stores and beauty parlours, 'Customer' is the unit of sale; for restaurants, 'Diner' is the unit of sale.
- Unit Price = Total Billed Amount ÷ Total Number of Customers/Diners.
- BEP for multiple products uses Weighted Average Contribution Margin (WACM).
- Sales Mix is the predetermined proportion in which multiple products are sold.
- WACM = Σ (CM per unit × Sales Mix %) for each product.
- Cash Flow = Movement of money in and out of a business.
- Cash Flow Projection is future-oriented; Cash Flow Statement is past-oriented.
- Opening Balance + Net Cash Flow = Closing Balance (which is next period's opening balance).
Common Mistakes to Avoid
Break-even quantity for multiple products is simply the sum of individual break-even quantities of each product
ROI and ROE will always give the same percentage, since both measure profitability
Unit Price means the price of one single item sold by the business
