We just integrated woo commerce but it appears that the shipping, discount and tax (sales tax when product is sold in the same state as business) on our previous orders that were automatically imported, isn't being included in the import. Shipping is a huge cost factor of business and should be accounted for, otherwise all the reports are useless - same goes with tax when item is sold in same state. Hope this gets added!
Shipping, discount etc are available on the the invoice tab not on sale order tab. Please have a look. Tax information is available on Setup tab of your WooCommerce integration page. Please make mapping between your Standard tax rates and specific tax rule in DEAR.
