There is an eCommerce add on (add page) that allows your customers to download your whole catalogue as a spreadsheet, and then after updating the require quantities offline, they can then reimport the file for a faster checkout experience.

Click on WEB PAGES from the main menu, then ADD PAGE, and find the page under the eCommerce add-ons section.
