As a SALESMANAGER you are able to change the date of sale. Once the status of the card has been changed to sale, you will find the icon to change the date.
In the Sales Opportunity section, you have the Sales Date field
To change the date, click on the calendar icon to the right of the sale status.
A calendar will display to choose the date when the sale was actually made.
Now you can change the date. Once you've chosen your new date, click anywhere on the page and a pop-up will appear to confirm the date change.
By clicking yes, the Sales Date field will be changed. This will affect your sales table. Please note that it will not have a red card, as the sale date will not be today.
