So our our use of Bill.com has been seamless. We're generating all of our invoices from Bill in a way that does not require us to be dependent on QB. The QBOL integration is only so that Bill generates a QB invoice number, but we can do that with any other Bill integrated payment processor. Bill support has been fantastic, able to answer any and all of our questions regarding AP and or AR processing. The only downside, IMHO, would be the subscription fee which is not excessive but is unlike Melio in that. Our customers happened to prefer the Bill experience and some were already working with them so it made going with Bill a no-brainer. 

I do find it ironic that QB support is sending us support surveys for problems they've never even attempted to solve. We respond respectfully understanding their call center employees are simply reading off a script but understand it's Intuit as a company who refuses to fix issues while still charging customers for the services they've promised but can't provide.
