I’m trying to ascertain the best way to go about subscription modifications during a billing cycle. Let’s assume we have a monthly billing cycle for users. User A is currently charged $20 per month. The user add’s additional services during the billing cycle increasing that charge to $40 per month. They did so half way through the billing cycle therefore an upgrade fee of $10 should be taken now as the services will commissioned now. If relevant this would be done using the Stripe API but it’s more a matter of optimising the procedure.

I have a test subscription in stripe which has the “collection_method” set to “charge_automatically”. Using the test clock to simulate future payments, I see that at the start of a new billing cycle only draft invoices are being generated instead of being charged automatically. While creating a new subscription or changing the subscription from one product to another the automatic payment does work like expected.
