@crisp shadow do you have an example sub_xxx subscription ID I can look at?

to be clear, when you say 'usages', these are metered subscriptions where you're reporting usage records?

#

yes, these are metered subscriptions. In total we have logged 6 usages over the past 6 months, and the coupon was valid for 7 months. Now the 7 months have passed, and all of a sudden these 6 earlier logged usages are billed to the full price, not taking into account the coupon

thanks, looking

#

I'm not sure if this is an expected edge case or not. To be clear the invoice is generated because there's a usage threshold of 1 euro that you set(https://dashboard.stripe.com/logs/req_Pxzg2ZyMOKflRM) and yeah seems like when the coupon fell off, that threshold was recognised.
To be clear none of that usage had actually been billed for yet, since it was just being added to the active subscription and the coupon doesn't really do anything here. Coupons just reduce any invoices generated during the period they're active for, by the amount of the coupon(and there was no invoice between March this year and March next years so the coupon didn't really do anything). They don't mean "usage reported gets discounted by that coupon" which might have been your understanding.

So how can we prevent this from happening again? Set the duration of the coupon to 1 year? Since the price interval is set to yearly.
Or change the invoice threshold to 0€, so that each time we add usage to the subscription, a 0€ invoice is finalized and billed

I'm not clear if it is a bug or not though, since why wasn't the threshold triggered while the coupon was active, so something is wrong in my understanding too

#

ultimately I'd suggest writing to our support team to dig into it. Thresholds+metered billing+discounts might have some unknown edge case.
as for avoiding it, I think making the coupon last a year instead is the way to go, so the invoice in March 2022 is generated and charges for the usage accumulated in 2021, but that invoice should get reduced to $0 by the coupon, and a new billing cycle starts.
