Good Evening, @Tim Marshall. 

I hope your weekend is going great so far. At this time, there isn't a way to have Stripe as an option with the "pay now" function. However, your customer can choose some of the other options: 

• ACH bank transfer 
• Visa
• MasterCard
• American Express
• Discover 
• Apple Pay

You can learn more about rates per transaction through this link provided. 

If you have any other questions, don't hesitate to ask. Take care!
