Tipping and adding gratuity is easy with Payment for Stripe. It happens after the initial charge, and is calculated based on percentages from the charge amount (excluding tax). We have some plans to add custom amounts in the future, but for now, options are: 10%, 15%, 17% (most common) and 20% calculated on the pre-tax amount. Whichever tip is chosen, your customer will see a separate charge for that amount. The customer will receive two receipts (if you've added an email), one for the original charge and one for the tip. Stripe and application fees apply.
First, ensure you enable tipping in the Settings menu:
Then, go ahead and create your charge:
Press the `Add Tip` button, then hand your device to your customer:
You'll then see a confirmation message that the tip was collected!
