Moonlight supports paying invoices with either a credit card or through a bank account ACH debit. At this time, ACH payments through company bank accounts can only be used when paying US-based developers. When paying invoices where the developer resides outside of the USA, only credit or debit cards may be used.
This ACH limit is set by our payment processor, Stripe. We are in contact with the Stripe team regarding this issue, and we will update this article if these rules change.
