Thank you for posting here in the Community, @Trogers21. Allow me to go into details as to what could be the best course of action regarding the matter at hand.
Please know that QuickBooks Online (QBO) does not support the combination of three estimates from different sub-customers into one invoice while reflecting each sub-customer's name on the corresponding line of the invoice.
However, you can consider manually creating these estimates and then converting each to an invoice, assigning a class to each item, as a workaround.
It's important to note that while using a class is useful for tracking, it won't be reflected when the invoice is printed or sent. Therefore, I encourage utilizing the description field, as this will reflect properly when printed or sent.
I recognize the significance of being able to merge estimates into one invoice and display each sub-customer's name on each line. You can provide direct feedback to our Product Development team so they can consider adding this feature in future updates. Here's how you can do that:
- Go to the Gear icon at the top.
