My comment was on how to signup for "QuickBooks Bill.com $9.99 payment service", not how to make an ACH payment through QBs. With the QuickBooks BBill.com $9.99 payment service" you can enter in a vendor's bank account details and the payments can be made electronically, not sure if they use ACH. If you do not have the bank account details then Bill.com will issue and ail a check.
