I emailed a customer an invoice, then deleted it by mistake. The customer called saying the invoice was deleted and they were no longer able to view it. If what your saying is true, why did it disappear on their end? Is there a way to change this? 

Hi, @Traciej. I'm glad to have you here in the Community thread. It's my pleasure to provide you some insights about the deleted invoices in QuickBooks Online (QBO).

Your customer won't be able to view a deleted invoice in QuickBooks Online if the aforementioned invoice was intended to be paid via online payments. It's because if they click the link for Review and Pay, they won't be able to see the contents of the deleted invoice in your QuickBooks Online.

Please see the sample screenshots below:

If you want to recreate the invoice and send it again to your customer, you may refer to this article: Create invoices in QuickBooks Online.

You might want to set up and send progress invoices in QuickBooks Online. You can divide an estimate into as many invoices as you need with progress billing. You can charge customers for partial payments rather than requesting full payment at the start of a job. This keeps project payments connected and structured throughout.
