Hello, Frank. 

I appreciate your time in sharing your sentiments about QuickBooks Online. I would like to take this opportunity to address the part about adding two dates on each line entry on a bill. 

As mentioned by my colleagues, we can only create a single bill for a specific date. And just like what you've mentioned, we're unable to put a date on each line of entry. 

For now, we could create two bills for the two different dates in QuickBooks. 

I would still recommend sending feedback to our developers about the ability to put a date on each line entry, if you haven't done it yet. Let's click on the Gear icon, then select Feedback. 

Our developers will read through your inputs and might consider them for future improvements and updates on the program. 

If you'd like to review your bills, payments, and other entries through reports, I'll share this article in case you need help in the future: Run reports in QuickBooks Online. 

I'm all ears and ready to help you out if you have other concerns about your bills. Would you like some assistance on other entries such as your sales as well? Include the details in your reply and I'll assist you again.
