Can I add billable charges to an existing invoice that has not been sent when charges are not displayed to click and add? ?

Thank you so much!  Never noticed that little arrow.  Suggest adding this coaching tip to the "adding billable expenses" instructions. Thank you for making my day!

wheres the arrow

I appreciate you joining the thread, @ss244. Let me clarify things about accessing the small arrow to add billable expenses to the invoice page. 
 
Sometimes, the sidebar will automatically appear without clicking the arrow as long as the customer has an open linked transaction.

If you're using the old design, we can open the invoice and click the small arrow to open the left sidebar. Make sure the customer has an open billable expense or any linked transactions; otherwise, the arrow won't appear. I'll show you how:

1. Go to the Sales menu and choose Invoices.
2. Click the Edit button for the invoice you want to modify.
3. From there, you'll see a small arrow (<) from the upper left side of the invoice page. 
4. Click on it to open the sidebar. 

All open transactions linked to the customer will appear on the sidebar including the open billable expense. You can filter the dates to show the specific transaction you want to add. 

If you're using the new invoice design, we have a different way of accessing the open transactions linked to the customer. Here's how:

1. Go to the Sales menu and choose Invoices.
2. Click the Manage Gear icon and choose Suggestions.
3. Hit the Suggested transactions link.
   
   
    
4. From there,  filter the Transaction type.
   
   

To know what else you can do with the layout of the new invoice, refer to this resource: See what’s new with estimates and invoices in QuickBooks Online.

With the new version of invoicing, you can update and personalize your forms during creation. All the customization tools for your sales are available on the form itself.

Under the manage gear I do not have the suggestions option listed.
