Use the Search function to find the sales invoices to be sent, select a sales invoice by right-clicking on it, click on the More actions button and select Approval / sending of multiple sales invoices.
Selecting the option opens the Approval > sending of multiple sales invoices page, on which you can prevent the approval/sending of the invoice by unticking the leftmost column.
Clicking on the Approve selected button will approve the sales invoices.
Clicking on the Send selected button will send the sales invoices. This function can also be used to send unfinished sales invoices that have not been approved.
The Select all button can be used to select and deselect all sales invoices on the list.
