hi! I'd need to test it but I think you can just add invoice items to the subscription normally and there's a final invoice at the end of the period

#

here is an example of event that is sent when a subscription is finally cancelled, the only invoice id I see is the latest_invoice

yeah I just tested it with Test Clocks and a final invoice is generated

real jungle here is an example of event that is sent when a subscription is finally cancelle...

yep but to be clear I mean

create subscription date X, next billing is in a month on Y
at X+5 days set cancel_at_period_end: true
at x+7, create a pending invoice item (https://stripe.com/docs/billing/invoices/subscription#adding-upcoming-invoice-items)
on Y, we create an invoice that charges for the outstanding pending item, and the subscription is cancelled

at x+7, create a pending invoice item

the first 2 steps are correct, then from X+5 to Y the user uses the app and when the subscription cancelled event comes at Y I want to create an invoice to charge "somthing" that is calculated at the end of the period

#

can you calculate it before then?

#

it would be much easier

#

then it would just work the way I say, you fire off an API request at any point during the period and forget about it

real jungle Jun 2, 2022, 9:38 AM

#

no because that's a comulative sum that can change untill the end

unborn saffron Jun 2, 2022, 9:39 AM

#

then I'd say your options are
1 - set up a cron job or something else to remind your system to calculate+send the API request e.g. an hour before the subscription is going to end
2 - if it really has to be after the end of the period, you'd have to create a one-off invoice(https://stripe.com/docs/invoicing/integration) for the amount

#

I think that creating a one off incoice for that amount is ok 👍 ,
what is the best way to do that since the subscription at that point will be cancelled, can you create an invoice without subscription?

#

here is an example of empty invoice and that fails..

i = Stripe::Invoice.create(customer: 'cus_LnlcXZSPBiQJeu')
Stripe::InvalidRequestError: Nothing to invoice for customer

What I was thinking doing is to create an empty invoice, then attache the lineitem and then close the invoice

unborn saffron Jun 2, 2022, 9:47 AM

#

you can't do that

#

you have to create the item first, then the invoice, that's how the Invoicing API works unfortunately (see the guide I linked which describes how to create the invoice item and then the invoice, which 'sucks in' the pending items)

I see, ok it makes sense! I would just need to invert the calls 🙂
