QBO - How to send one invoice for multiple offices.

I have a solution on how you can enter your offices in QuickBooks Online, SWyatt502.

You may have checked the Is sub-customer box when setting up your office's profile and selected the Bill this customer option. That's why Offices A is receiving the emails.

You can use the class tracking feature instead of projects. To start, you'll have to turn on class tracking first. Here's how:

1. Click the Gear icon and select Account and Settings.
2. Select Advanced, then select the Categories section to edit.
3. Check Track classes.
4. Check Warn me when a transaction isn’t assigned a class. This is optional, but it's good to turn on so when you look at reports, you know everything got classified.
5. Under Assign classes select One to entire transaction or One to each row in transaction.
6. Click Save, then Done.

Then, assign different classes for your offices. 

1. Click the Gear icon and then select All Lists.
2. Select Classes.
3. Select New. Give this class a name.
4. To add a sub-class, select Is a sub-class and select the main class. You can nest up to five classes.
5. Click Save.

Once you're all set up, you can now track your transactions by class. And this won't mess up your reports.

You'll want to run and customize reports in QuickBooks Online to show the information that you need.

Thanks for the advice, but I'm not following how this would work.  

Office A just handles all the payables for the other 15 office, but each of the other 15 offices has their own, individual bill.  Example:  Office A's bill = $250 Office B=$700, Office C = $650, and so on.  Since they are individual bills, the customer name and address is individual to that particular office. But bills need to be sent to Office A for payout.  Make sense? I'm starting to think there is no way to do it and I'll just need to handle this customer base differently than the rest by sending a statement for all accounts. 

Thanks for following up, @SWyatt502. 

As of now, this option isn't available yet. Rest assured, I'll make sure and share it with our Development Team to potentially be added to our future updates.

The assigned one location on the invoice applies to the entire transaction. For now, there's no option to divide the invoice to multiple locations. You might want to create different invoices for each location. 

On the other hand, you can follow the workaround provided by my colleague, @MariaSoledadG. You can either create different invoices for each location, or you can use class tracking.
