Is there a way to email a remittance slip to suppliers to make them aware an electronic payment is coming?

Hi there, PB.

At this time, printing a remittance slip in QuickBooks Online (QBO) isn't available. You can send feedback about printing remittance slip by following the steps I've outlined below.

1. Click the Gear icon at the top, then Feedback.
2. Enter your comments or product suggestions. 
3. Select Next to submit feedback.

This valuable feedback goes to our Product Development team to help improve your experience in QuickBooks. You can track feature requests through the QuickBooks Online Feature Requests website.

For electronic payments, you can set up the supplier's bank account and pay them via direct deposit. With this, payments are recorded accurately and automatically in QBO.

To start paying a supplier electronically, here's how to set up the vendor's bank account.

1. Set up your company payroll for direct deposit.
2. Invite your supplier to provide their W-9 business and bank account information to you. 

Or you can manually add the supplier's account info. 

1. Select Payroll, then Contractors.
2. For a new contractor, select Add a contractor or select the existing contractor to add or edit bank info.
3. Select Bank account.
4. As prompted, enter the following:
   • Account Number
   • Account Type
   • Routing Number
   • Account holder Phone Number
   • Account holder Full Name
5. Click Save.

Once done, you can now pay your vendors through direct deposit. 

If you don't want to pay suppliers using direct deposit, you can sign-up to Online Bill Pay and send payments online. These articles will guide you through the steps and discuss some details about how it works in our system.

You can signup for a separate Melio account for free to integrate with QBO. It will send a secure form asking for your vendor’s payment details and how they want to get paid. Once your vendor fills out the details, the app automatically schedules the payment according to the date you chose & updates you with the final estimated payment delivery date. The same with your vendors/contractors, once they click on the link in the email, your vendor/contractors can choose how they want to get paid (via paper check or bank deposit) and the details of where to send or deposit the payment and when they will receive the payment. Then don't need to signup anything and you don't have to bother sending anything from QBO.
