Billed a customer. Payment was declined. Created new invoice. R resent it, He paid. Need to void the invoice and payment that is recorded but was actually never received.

Let me chime in on this conversation melissamacdonald to provide steps about voiding your invoice in QuickBooks Online (QBO).

Make sure to void payment the first. Here are the steps how:

1. Go to Sales, then Customers.
2. Locate the customer of the said invoice you want to void.
3. Click the dropdown arrow under the Action column.
4. Select Void then a prompt will show up and choose Void

Next is to void the invoice itself. Here's how:

1. Go to Sales, click Invoice
2. Choose the invoice you want to void.
3. Under the Action column, click the dropdown arrow.
4. Select Void then a prompt will show up and choose Void.
