Hello
pastel delta

bleak swan

Great, thanks

So i am trying to update a subscription for a client, but i want pro-rated rate
which mean, if client is sub to 100$ product, and he want to sub for a 200$ product, i want to charge him 100$ only.
so a nice guy from here says i need to use https://stripe.com/docs/billing/subscriptions/upgrade-downgrade method.
just want to ask, it have two way to do it
-Update the subscription
- Update the subscription item
i just want to ask, will both method then charge the customer the remaining amount automaticly whcih one should i use.
and i also want to get notified when the charge is done. for that shoudl i enable a webhook with customer.subscription.updated event
bleak swan
Do these different products have the same billing interval?
(Like are they both monthly?)
pastel delta
yes monthly
bleak swan
Okay and are you okay with the new product being charged at the next billing cycle but include the prorated rates?
Or do you want to charge it immediately?
pastel delta
yah nice question, i want the charge be imidiately but billing cycle remain same
bleak swan
Hmm okay you can't really have both of those things
pastel delta
what do you mean, i am only changing one product to another , i dont want to keep the previous product.
bleak swan
Yeah but you can't charge a prorated amount immediately in the middle of the month and then also charge the customer again the full amount at the end of the month.
I mean... you can... by using a trial period, but that ends up charging your customer more than the amount of product they actually get.
If you want that behavior I can describe it to you, but why not just wait and charge them at the normal billing cycle?
pastel delta
hmm nice edge case.
but i am then giving him the 2nd product which is is more feture and the prorated price is which is the deduction of current produt with previous one, is for new feture whcih he gonna use
bleak swan
Or why not just reset the billing cycle anchor so that they are now charged in the middle of the month going forward?
bleak swan
but i am then giving him the 2nd product which is is more feture and the prorate...
Correct, that is how the proration will be calculated
pastel delta
no mattar for billing cycle it can be resetted stating for current date
bleak swan
Okay well then yeah you basically want to update the Subscription as we show here (https://stripe.com/docs/billing/subscriptions/upgrade-downgrade#changing) and change the Subscription Item to be your new Price.
If you don't set proration_behavior at all then the billing cycle anchor will be the same and an Invoice Item will be added and charged at the next billing cycle renewal.
Otherwise, if you want to charge immediately, you set proration_behavior: 'always_invoice'
pastel delta
it have too call shoudl i use ** Update the subscription item** or ** Update the Subscription**
And it will Charge the customer and trigger the event customer.subscription.updated
bleak swan
You should use the Update Subscription endpoint
And yes a customer.subscription.updated will be emitted
However it will only charge if you set proration_behavior: 'always_invoice'
The best thing to do is to test this out
You can use test clocks (https://stripe.com/docs/billing/testing/test-clocks) to do this quite easily
pastel delta
Thanks a lot @bleak swan sir ♥️
bleak swan
Sure
