The Stock Group Summary screen summarises your Stock Group (i.e. Food and Liquor) sales and purchases, and calculates a weekly Gross Profit based on these. This allows you to track your weekly stocks and GP%.
Using the example above, the net food sales were £11,083.34 for the week.
Opening Food Stock (if counted each week) - is the closing stock from the previous week, carried forward.
Total purchases (cash and account): £500
Closing Food Stock (if counted) - is the value of your food stock on site at the end of the week.
£5,000 + 500 - £4,000 gives a Cost of Goods Sold of £1,500.
This gives a Profit of £9,583.34 for the week (Total Food Sales - Cost of Goods)
This converts to 86.47% ((9,583.34 / 11,083.34)*100)
