How do I export multiple invoices at once?

From the list of invoices on the Export tab, select the rows you want to export by using the checkboxes, or by holding down the 'Ctrl' or 'Shift' button while you select rows with your mouse. Once you have made your selection, click the “Actions” button on the top right corner, and choose 'Export'
 
Or you can also "Export all" and "Data". This will export all fully approved invoices out of Beanworks.
