You have options to consider to achieve your goal, @MarkItEmporium. Happy to share that with you. 

I'll make sure that you can re-send your invoice without deleted tag in QuickBooks Online. 

Yes, the deleted tag will appear on the invoice if you send it back to your client. But no worries, the options outlined below will help you send the invoice to your customer as the deleted item status will be hidden.

Option 1: You can make the inventory item active again and re-send the invoice to your client. Then after, make them inactive. 

Here's how: 

1. Go to the Sales tab, then select Product/Services. 
2. Click the small drop-down arrow beside the tunnel icon. 
3. Pick Inactive and choose Apply. 
4. Hit Make active

Option 2: Print the invoice as a Packing Slip and manually email it to your customer. Before that, let's customize your invoice sales form so the deleted status will be invisible. 

Proceed as follows: 

1. Go to the Gear icon and choose Custom form styles. 
2. Select your template and pick the Content tab. 
3. Click the second pencil icon and uncheck the Product/Service box.
4. Hit Save. 

Once done, go back to the customer transaction list and follow the steps below: 

1. Click the small drop-down arrow perpendicular to the invoice you want to re-send on the Transaction List page. 
2. Pick Print packing slip. Ensure that the invoice description is the same as the item name to identify it quickly. 
3. Instead of printing, hit download ⬇ and manually send it to your client.
