Hello, @kpthompson.

Thanks for taking the time to stop by the Community. Allow me to share some insight on QuickBooks Bill Pay. Through this feature, ACH is the method of payment. Most transactions happen the next business day, but it is advised to allow for 4 business days for the payment to fully process.

Other bill pay solutions may offer additional payment methods. You can search for other providers in the Intuit App Center. I've included a link for that site here. Should you need it, I'm also including an FAQ link for QuickBooks Bill Pay here. If you have any additional questions, feel free to leave me a comment down below.
