1. Not directly. Instead you'd process a one-time payment for X and then manually increment their balance via https://stripe.com/docs/api/customer_balance_transactions/create
2. That should be how it works automatically when the associated Customer object has a positive balance: https://stripe.com/docs/billing/customer/balance#details

so creating manual payments e.g. with certain meta-data, and then using webhooks to update the balance should work?

[little hinge]

Yep that's a common flow for people leveraging the balance

[thorn nymph]

if we just delete all payment methods from the customer, no automatic charge can be made as well

does that produce errors when the invoice totals to 0$ because of the balance?

[little hinge]

Not sure I understand. If you want to prevent any automatic payment attempts when the balance is 0 then switch to collection_method: 'send_invoice'
