Hello

Can you clarify what you mean exactly when you say "apply a debit to an Invoice"?

[sacred frigate]

In these docs: https://stripe.com/docs/billing/customer/balance

.. it says this

Positive values are treated as a debit (an increase in the amount owed by the customer to you) that you can apply to the next invoice.

[placid pulsar]

Ah okay

So you are talking about Customer Credit Balance

In this case you can either adjust this via the API (https://stripe.com/docs/api/customers/update#update_customer-balance) or via the Dashboard

But the balance will only apply to the Invoice on finalization.

Otherwise to adjust a finalized Invoice you would use a Credit Note: https://stripe.com/docs/invoicing/dashboard/credit-notes

Docs say this:

The credit balance automatically applies toward the next invoice finalized to a customer.

Is the same thing true about debit balances?

[placid pulsar]

Yep

"Credit balance" encompasses both credits or debits in that balance

You can test this out pretty easily as well!

Thank you!
