Calculate mix from the same revenue total
Each category’s share uses the total revenue for the selected venue and period. A percentage based on a different date range can misrepresent the mix. Keep the category names and recorded sales inputs consistent across daily submissions.
Read category movement alongside total sales
A category can gain percentage share while its absolute revenue falls if other categories fall faster. Review AED values and percentages together. This distinction matters before treating a larger category share as a successful sales initiative.
Avoid using mix as a margin estimate
Revenue mix does not establish profitability by category. Purchase timing, stock accounting and missing costs can affect the interpretation. Use sales mix to select a question for review, then consult the appropriate cost inputs before making a margin claim.
