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 £4115.44 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): £1728.03
Closing Food Stock (if counted) - is the value of your food stock on site at the end of the week.
£4718.27 + 1728.03 - £4782.74 gives a Cost of Goods Sold of £1663.56.
This gives a Profit of £2451.88 for the week (Total Food Sales - Cost of Goods)
This converts to 59.58% ((2451.88 / 4115.44)*100)
