That approach seems sound, given what you mentioned about your use-case. Now let me tackle the individual questions.

after including the products for the invoice, how do we specify a booking fee on top of it? right now a simple hack is to use a custom tax value named Booking fee but it feels wrong
I wouldn't use Tax to include a fee. Is there any reason you couldn't simply specify the application_fee on one of the Payment Intents that gets created for the Invoice?

will this work with all the payment methods above?
Yup! Pretty much all the payment methods that you use with Payment Intents are also supported with Invoices, as Invoices are built on top of Payment Intents

one pro of using the payment intent is the ability to authorized the charge first at booking time and capture it at booking acceptance. Can we achieve this somehow by using invoice?
Yes! You would have to create a separate Payment Intent for the authorization and (on booking acceptance) either add that Payment Intent to the Invoice to charge the authorized amount, or cancel the Payment Intent and create a new one for an updated amount.

from my understanding, application_fee would be what taken out of the amount sent to the connected account, not adding on top of the total of the products. Ex: if the products total out to be $100 and our booking fee is $10, I'd like the invoice total to be $110. But if we specify the application fee, would that just be $100 still and the connected account would get something like $90 ish

thanks for the respond btw! 🙂

Ahhh, okay. Then in that case you would just add an Invoice Item to the Invoice for the amount
