14yrs ago at another company I did the below every hour
• At 10 minutes after the hour = My ERP system FTPed an updated comma delimited CSV file to a directory
• At 20 minutes after the hour = My eCommerce software (i.e. like Magento) processed the file, updating inventory, making “Qty=0” items INACTIVE so they don’t display on the site
What 3rd party Magento add-on can do this on the FREE version ?
