Hey! What do you mean by 'usage stats'?

spare rampart Jun 30, 2022, 11:20 AM

#

So I have a volume based object and I'd like to get the amount the invoice generated over the last billing period

#

Do you have an Invoice ID? There's no concept of 'usage' with volume pricing, it's just determined by the quantity set in accordance with the tiers defined on the Price

spare rampart Jun 30, 2022, 11:22 AM

#

I haven't implemented the feature yet

#

so no invoice id per se

#

but I'd just like to understand how much they used something in the last period

See: https://stripe.com/docs/products-prices/pricing-models#volume-based-pricing

Pricing models for recurring billing

Learn about common pricing models and how to model them with products and prices.

#

ah so use quantity?

#

from the retrieved invoice

arctic ginkgo Jun 30, 2022, 11:25 AM

#

Yes, the subsequent invoice would be itemised to reflect the usage throughout the period

spare rampart Jun 30, 2022, 11:26 AM

#

in the lines data i have to use the quantity provided?

#

in the last generated invoice?

arctic ginkgo Jun 30, 2022, 11:28 AM

#

That would reflect the most recent 'usage' for the billing period yep. However they may have upgraded/downgraded mid cycle so there could also be proration items for more/less quantity, depending on how you handle that

#

You can simulate all this quite quickly with clocks: https://stripe.com/docs/billing/testing/test-clocks

#

What do you mean downgraded in the last cycle? Would this affect the quantity?

arctic ginkgo Jun 30, 2022, 11:31 AM

#

Well your customer may decide they want less (or more) of whatever your selling and as such you'd update the quantity of their subscription to reflect that: https://stripe.com/docs/billing/subscriptions/quantities

Setting subscription quantities

Vary the cost of a subscription by subscribing a customer to multiple quantities of a product.

#

You can decide whether to prorate those changes, not sure how that works with volume pricing: https://stripe.com/docs/billing/subscriptions/prorations

Prorations

Learn about prorations.

#

Actually, don't think that applies as the volume based stuff is invoiced at the end of the billing period

#

So if you started the cycle with 1 and updated to 2 at the end of the cycle, they'd be invoiced for 2 regardless

spare rampart Jun 30, 2022, 11:34 AM

#

Right, I think I understand

#

so to get the quanity used in the last complete billing period we just need to get quantity?

arctic ginkgo Jun 30, 2022, 11:35 AM

#

Yep exactly

#

Which would be on the invoice

spare rampart Jun 30, 2022, 11:35 AM

#

ah ok interesting

#

yep that makes sense

#

another q which is unrelated

#

are we able to use send_invoices to our connect customers?

#

sorry the end user for our connect customers

#

so on behalf of them?

arctic ginkgo Jun 30, 2022, 11:39 AM

#

Pretty sure you can, don't see why that wouldn't work: https://stripe.com/docs/connect/subscriptions

Create subscriptions with Stripe Billing

With Connect, you can create subscriptions for your customers or connected accounts.

#

ah ok

#

that's interesting

#

i'll give it a go and see if it works

#

i was told previously that it may not work

arctic ginkgo Jun 30, 2022, 11:43 AM

#

Yeah I'm not sure tbh! Should be easy to test

spare rampart Jun 30, 2022, 11:44 AM

#

yes true

#

i'll give it a go

#

thanks for your help on this

arctic ginkgo Jun 30, 2022, 11:44 AM
