How do I add multiple customers to one invoice? (The bill is to be split evenly between them.)

Welcome to the QuickBooks family, @melissabuffingto.

I can share some insights about entering sales transactions in QuickBooks Online. Currently, the system only supports one customer every single invoice.

Since adding multiple customers is unavailable, I suggest creating a separate transaction for each one of them. You can manually calculate the amount to split them evenly.

Here's how to create an invoice:

1. Click the + New button at the top.
2. Select Invoice. 
3. Add one customer. 
4. Enter necessary information. 
5. Hit Save and close.
6. Repeat steps 1 to 5 for the next customer.

I understand how the workflow you're looking for is beneficial to your business. To ensure your voice is heard, I can pass along another feature request on my end.
