You can email forms in QuickBooks for Mac. The process differs slightly depending on the version of QuickBooks you use.
You can email any of your forms directly from QuickBooks. The form is saved as a PDF file and attached to an email message which is sent using your default email program. QuickBooks uses the email address saved in the customer list to send the sales form. QuickBooks supports Microsoft Entourage and Apple Mail.
Email sales forms
You have two options for emailing invoices, estimates and other sales forms.
Option 1: From the form window
Option 2: Email later
