When I send an invoice by e-mail, the QuickBooks system duplicates my customer invoice. How do I solve this problem?

Hello, bobpres.

I'm on the case, and I'll help you solve the duplicated emailed invoices. 

You'll want to check for recurring transactions that might've been scheduled to send on a specific date. These can cause your invoices to send twice to your customers. Here's how: 

1. Click the gear icon, then select Recurring transactions.
2. Find the recurring transaction template that might've been scheduled when you sent the invoice.
3. Click on Edit if you need to change the date. 

If there aren't any recurring transactions, you'll want to send the invoice to your email address. If it doesn't duplicate, then this might be caused by the customer's email settings. Reach out to them to check their settings to avoid duplicate invoices. 

Also, check for the Cc/Bcc field box to see if the customer's email address is set for a carbon copy setup. Simply open the invoice, then click the Cc/Bcc link under the Customer email box.
