What is the fastest way to pay an AMEX card?

Hi! Just wondering what the fastest payment method is to pay down an AMEX credit card? BPay is fairly quick but still takes over 24 hours for me, sometimes 48+ hours when sent on a Friday. Just wondering if there is a more immediate option?
BTW, I don’t mean paying off the monthly credit card bill, I mean sending regular payments throughout the billing cycle to allow my business to spend more throughout the month.


Hi neruson,

I’m no expert on this but you might like to check out Osko. I’d never heard of it until someone used it to transfer money into my bank account a few days ago, and payment was literally instantaneous even though it was after-hours. If AmEx accepts Osko, you might just be in luck.
