In this example, we have assumed that the guest with order #62 has paid the due amount, gave you a tip, and left the restaurant. Now you have to add that tip to order #62. Let us see how we can do this.
Refer to the screenshot, click the Left Navigation button.
Click the Orders button on the left.
Click the Closed Orders button at the bottom.
In this example, we want to add tip to order #62 so we tapped on 62 under the Order# column. In your case, you should click the order number to which you want to apply the tip.
Click the Tip button at the bottom navigation bar.
Enter the tip amount that customer gave you under the Cash Tip field. In this example, we have assumed the guest gave you a $3 tip.
Add it to the field and click the Apply button on the top right.
Once done, you can see the $3.00 tip amount has been added to the order#62.
