You can now send all your invoices through Link4, even if your customers are not using Link4 or any cloud accounting software. They will be able to receive your invoices in the form of a PDF email attachment through Link4. You don't have to create the email. Link4 will create the email and automatically attach a PDF version of the invoice for you. 

This feature is disabled by default but if you would like to enable this feature, follow these steps:

(1) Click on "Settings", then "Approval".
(2) Enable the feature by clicking on "Yes" at "Send PDF invoices to customers who are not connected to Link4".
(3) Now all of your invoices will be sent through Link4.
