Yep, unfortunately prorations are 'dumb' to whether the related invoice paid or unpaid so they're applied regardless if the proration_behavior param passed on the upgrade/downgrade requires

You can just manually adjust the balance if this is a problem: https://stripe.com/docs/billing/customer/balance#modifying

Ok thanks for your quick reply 🙌 , is there something you would recommend checking on our end? to prevent this from occurring again

Well what is the desired behaviour? Do you want to prorate (credit) for unused time in scenarios where a user upgrades/downgrades?

If the customer haven't paid for the pending invoice = no credit

Then you'd need to implement logic in your application that handles the downgrades/upgrades to disable proration on the update if they have an unpaid invoice

Noted, do you have a guide/tutorial on this?

Nothing specific to that no. You'd likely need to list the invoice for that subscription/customer (https://stripe.com/docs/api/invoices/list) and check if there are any still open/unpaid. If there are, then pass proration_behavior: 'none' when you make the API call to update: https://stripe.com/docs/billing/subscriptions/prorations#disable-prorations
