I believe so. We can double check if you want. Have you gotten far enough in testing to where one of these subscriptions have completed a first payment with those additional items?

I haven't gotten there yet

How close are you? I can test myself but if you can quickly create a subscription like this that might be faster

Never mind, found it in our docs. Application fee is based on the total of the invoice including those one off fees https://stripe.com/docs/connect/subscriptions#collect-fees

One time each billing period, Stripe takes this percentage of the final invoice amount, including any bundled invoice items, discounts, or account balance adjustments, as a fee for the platform. We make this deduction before charging any Stripe fees.

Is that your intended behavior here?

[frosty quiver]

Yes, the problem is that the application fees are sent as a percent only once (when creating the subscription). So, for the following invoices (which don't have one time invoice items), the fees might be a little off.
This is because we include Stripe's processing fees (2.9% + 0.30) in the application fees.

The $0.30 make the application_fee_percent different, since the total is more in the first invoice but less in the following invoices

Hey @frosty quiver apologies for missing your followup. The total application fee will adjust next payment, it will drop whatever part of the fee was from those additional invoice items. If you want to adjust for that, you can change the application_fee_percent on your subscription with a subscription update call in the API
