Hi, @mightyoaklandsca. It's great having you in the QuickBooks Community.
ACH payment is generally a more secure payment option since Nacha oversees the ACH Network to ensure safety, and QuickBooks complies with Nacha. Yes, QuickBooks also allows refunding a customer's ACH payment transaction and chargeback when a customer disputes the ACH transaction with his financial institution.
However, do you mean processing ACH payments for customers or vendors in QuickBooks Online (QBO)? Nevertheless, let me help you by giving resources as an overview of both.
If you're considering signing up for QuickBooks Payments for processing customer ACH payments, you can refer to these articles:
You can also process ACH payments for paying your bills through QuickBooks Bill Pay. Refer to this article as a guide to learn more about this: Learn about QuickBooks Bill Pay.
For future reference, you can refer to this article to learn more about how QuickBooks helps keep your customer payment card data safe: PCI Compliance.

I owned a semi repair shop in Houston, customer paid a bill for 11500 dollars thru an ach transactions, money hit my account next day, 3 days later it was withdrawn from my account the truck is gone with me not getting pay, quick books does not have a clue who made that payment and my account is backwards because of it. Totally not reliable. I don’t even know who to call , or who wrote the check. If you are getting paid make sure the checks goes thru first otherwise you will be scammed .extremely not thrusworty
