The Online Store allows for invoices to be saved as PDF documents, which make emailing them a breeze.
To access and save the invoice you're looking for, simply do the following:
- In your Sitebuilder, click Menu > Store.
- Click My Sales > Orders.
In your list of recent transactions, find the one that you would like to save and/or send the invoice of and click Print invoice, located to the right of the transaction.
This will open a screen that allows for the invoice to be saved to your computer, after which you can attach it to any outgoing email.
