One of the complaints that I always hear from my clients is, “How do I verify that the invoice that I e-mailed in QuickBooks was actually sent?”
To e-mail an invoice to a client, click on the “send” button at the top of the invoice and follow the e-mail wizard.
When finished click on the “history” button at the top of the invoice and it will show you the date that the invoice was sent and how it was sent.
Now you have a record of the date that you e-mailed the invoice.
However, if you send the invoice more than once, by e-mail, the date under the “history” button will update each time you e-mail the invoice to the date of your e-mail and you will lose any prior date information.
