Or should I do Adjust Credit Balance on the customer and add the monthly charge to give them an extra month?

Hi, yes, you should be able to update the Subscription via the Dashboard.

I recommend that you try this out on your account in test mode.

Thanks. So add trial days on the subscription is better than adjust credit balance on the customer?

It's up to what you're trying to do. What are you really trying to achieve? Can you add more details?

[half radish]

I just want to give the customer an additional month on their subscription and make sure it doesn't try to bill them again until next month

I see, that is not how it's going to work. It will calculate prorations, https://stripe.com/docs/billing/subscriptions/prorations and I'm afraid it's going to have unintended side effects.

In this case, you can just void in the invoice.

FWIW I don't use trials in my product so I'm unfamiliar with that

I highly recommend that you try this out in your account in test mode.

Could I "issue a credit note" on the invoice which is currently in the "Retrying" state?

[uneven cloak]

You could on that invoice via the Dashboard and that will be bring the invoice to paid status.
