There are two ways of sending an invoice:
Option 1: Sending it directly upon creation
Upon creating an invoice, there are four - more or less self-explanatory - ways of saving your invoice you can choose from.
|Save Draft:||Saves your invoice as a draft.|
|Save:||Saves your invoice with a status depending on its previous status, due date and balance.|
|Save & Send:||Saves your invoice and takes you to the invoice sending editor.|
|Save & Mark Sent:||Saves your invoice and marks it as "Sent".|
Option 2: Sending it from the invoice page
If you are looking to send an existing invoice, simply open it and choose "Send invoice" from the top right Actions menu.
