Hi

I understand why it does that but what I need is to get prorated price with applied coupons for the additional seats, without taking into account the whole subscription state. How can I do that?
You can't achieve that, upcoming Invoice are related to the actual and whole state of the subscription.

Probably you should compute this on your end if you want display this particular use case.

Regarding my issue again
I think I found a workaround:
In retrieve upcoming route, instead of specifying the end quantity in the subscription_item like that
...subscription_items: [
{
id: subscriptionItem.id,
quantity: 12,
},
]...
I am specifying the additional seats quantity
...subscription_items: [
{
id: subscriptionItem.id,
quantity: 2,
},
]...

The upcoming invoice then returns line items and the second one is “Remaining time on 2 × … (with 25.0% off) after 12 Apr 2023” - it has the desired result. But this solution also has one problem - when I pass quantity that equals current quantity in the subscription, this line item is not returned. That is, when I pass 2, 3, 4…9, 11, 12… - it returns this line item, but when I pass 10 - it does not return that. Is this some sort of a bug or desired behaviour?

Can you share some example req_xxx IDs that demonstrate what you're describing?

The one that working - req_C9PsfvpjzkyYfp
The problematic one - req_4kVSi8LFIaPGvH

Can you share the critical difference in the JSON responses? We don't log those

The upcoming invoice has lines.data property - the first request returns 2 line items, the second one only 1.
In the first request 2 line items are with such description:
{… description: ‘Unused time on 10 × … after 12 Apr 2023’}
{… description: ‘Remaining time on 2 × … (with 25.0% off) after 12 Apr 2023’}

In the second request only 1 line item with such description:
{…description: ’10 × … (at $200.00 / month)’}

That would be great to have Remaining time on 10 × … line item.

Must to say, initial quantity in subscription is 10.

Well you're passing the same item quantity (10) that already exists on the Subscription. Why would there be any proration there?
