ACH / Epayment that links well with Quickbooks

[Rich Zellmer]

I was grandfathered in to Quickbooks $.50 ACH fee but they are moving me to a plan with a 1% ACH fee.  We do about 30K in rents a month so that can be a bit pricy.   Anyone recommend a third party billing service that integrates well with Quickbooks online and has a flat rate ACH fee - hopefully one that is $1.00 or less.
