How can I recover deleted invoices and payments?

Hey @dphelps, glad to have you here in the Community.

You can check the audit log to get the details of the invoice.  Here's how:

1. Go to the Gear (⚙) icon, then select Audit Log under the Tools section.
2. Once records are pulled up, you can use the Filter option to search through your history and locate the deleted record details.

Then, you can go in and re-create the missing invoice with the information you have recovered within the Audit Log.

If there was a payment attached to it before it was deleted, that payment will now show as unapplied.

Go into receive payments and you should see an unapplied payment from your customer.  You can apply that payment to the invoice.  For more information on receiving invoice payments, check out this article: Record invoice payments in QuickBooks Online.
