Does anyone know how to re-create a deleted invoice from a previous year and month without creating a transaction in your bank account for the current year and month?

Hello, pamcarcidoconsul. 

I'll walk you through how you can re-create an invoice without affecting your bank balance.  

You'll need to create a credit memo. Then, you can link this transaction later on to your invoice to close it.

Here's how:

1. Go to the + New menu.
2. Select Credit memo.
3. Choose the customer in question under the Customer drop-down menu.
4. Fill in the product or service under the Product/Service column.
5. Type in the amount as well. This should be the same amount on the invoice you wish to mark as paid. 
6. When done, click Save and close.

Now, we need to link this to the invoice. Follow the steps below:

1. Highlight the Sales tab.
2. Choose Invoices.
3. Search for the invoice in question, then click to open it.
4. Click the Receive payment button. 
5. On the Receive Payment page, ensure the only selected invoice is what you want to mark as paid. 
6. Under the Credits section, tick the checkbox for the credit memo you created earlier. 
7. Tap Save and close when done.

It would still be best to link the actual payment for this invoice. If it was recorded as a deposit, you can follow the steps in this article: How to link a deposit to an invoice.

Hello there,@pamcarcidoconsul.

Allow me to chime in and clarify things here, with regard to recreating a deleted paid invoice in QuickBooks Online (QBO).

To confirm, yes, you'll have to recreate the deleted invoice first, before creating a credit memo that will be linked to the recreated invoice. You'll then need to connect that to the unpaid deposit.

Also, yes, you can backdate those transactions. You can utilize the audit log to get the accurate date and information for the transaction you'll need to recreate.

Need to take a look at your sales reports after getting the invoices back or any other reports to keep track of your business's financial status? Take a look at this article: Run reports in QuickBooks Online. Please know that you can customize them that's also indicated in the article how.
