Your Vend Product Performance tile gives you the option to view a list of individual product performance by Day, Month or Financial Year and can also be set to view by Gross Profit or Sales.
Go into Vend and follow the steps to find the corresponding information.
1. Under Reporting select Sales Reports
2. Set the Report Type to Product and the Measure drop down to either Gross Profit or Revenue
3. Select the date parameter according to the Tile that you wish to find by Day, Month or Year and then apply the changes.
4. Depending on what option was selected in the Measure drop down you will now see either the Gross Profit or Revenue (Sales) based on your date search and this figure should match what is being shown in your Tile
