A Donorbox account can only link to 1 Stripe account. And, only 1 bank account can be connected to that Stripe account.
If you need to deposit funds into multiple bank accounts, you should consider opening separate Donorbox + Stripe accounts for each bank account. This would work as follows:
- Donorbox A, linked to Stripe A; payouts would go to Bank A
- Donorbox B, linked to Stripe B; payouts would go to Bank B
Stripe only allows multiple bank accounts to link to a single Stripe account if you are working with multiple currencies, ie. each currency gets sent to a separate bank account.
