Your available Stripe balance may go into the negative if the cost of refunds or disputes is greater than the existing balance. You can add funds to cover existing negative balances or proactively add funds to be used for future refunds or chargebacks that will be held separately from your earnings, payouts, and funds from other Stripe products.

To do so, go to the section 'Saldos' in your Dashboard and click on the option 'Agregar al Saldo'.

The funds added through this process are used to cover for refunds and chargebacks only. If you are using Connect and is looking to add funds to pay out to connected accounts, this option is still not available in Mexico.
