Hi there, @info-ellitepoolc.
Open invoices can't be combined because they are created with different dates and customer details. Yet, I see how useful this feature would be on your end.
As a workaround, we can send a statement indicating transaction details and the balance due to your customer. However, we can send this one at a time. Here's how:
- From the Sales tab, go to Customers.
- Click the name of the customer you want to send the statement first.
- Select the Statements option below.
- Choose the dates you want to send statements to that customer. Then, click Batch actions above the list and tap Send.
Check out this article for more info: Create and send customer statements in QuickBooks Online.
Also, you can look for a third-party application to perform this function.
In the meantime, you can submit direct feedback to our Product Development Team and enter your suggestions about open invoices. They might add this to our future product updates.
Suppose you want to personalize your sales forms. you can read this article: Customize invoices, estimates, and sales receipts in QuickBooks Online.
