How do I find/send a customer’s statement?

To view a customer’s statement, go to the customer’s page, click ‘Sales orders & credit notes’, and click the smaller ‘Actions’ dropdown button under the ‘Unallocated account payments/credits’ section, where you’ll find the ‘View account statement’ button.

From there if you go to the print preview of the page (File > Print, or CMD/CTRL + P), and change the destination to ‘Save as PDF’, you can save it in a more sendable format.
