I appreciate you chiming in on this thread, JSKCI. I've come to share additional information to help you generate a remittance email to your vendors.

Currently, the option to email remittance when making vendor payments is unavailable in QuickBooks Online. However, you'll want to run a bill-related report and send them to your vendors. You can either open a transaction journal report from a specific bill payment transaction or run a Bill Payment List report as a workaround.

To open a transaction journal report from your bill payment transaction, you can follow the steps below. Here's how:

1. Go to Expenses from the left menu bar and click on the bill payment transaction.
2. Under the Payment Status from the upper-right corner of your Bill, click on Payments made.
3. Select the specific date to open the bill payment.
4. Click More from the bottom part of the transaction and select Transaction Journal.
5. Click on the Email icon to send them to your vendors.
6. Enter additional details and click Send.

You can also run the Bill Payment List report from the Reports menu. To do that:

1. Go to Reports from the left menu bar and enter Bill Payment List.
2. Modify the specific Report period date and select Vendor from the Group by dropdown.
3. Click Customize to add other details to your report.
4. Then, select Run Report.
5. Once done, click the Email icon to send them to your vendors.
6. Add additional information and click Send.

Additionally, you'll want to save and attach a screenshot of your bill payments when sending them to your vendors. 

Furthermore, to help us achieve your goal, I'd suggest sending this feature request to our product developers. This way, they'll consider your suggestion and might include them in future product enhancements.

Here's how to send feedback:

1. Go to the Gear icon.
2. Under the Profile column, click on Feedback.
3. Share your feedback. Then, click Next.
