Issue
Some users run into an issue where orders charged tax in WooCommerce sync to QuickBooks with a different total (often different by $.01) - even though tax rates are correctly mapped in MyWorks Sync > Map > Tax Rates.
Resolution
This can occur due to how QuickBooks rounds tax calculations at a subtotal level, vs how WooCommerce round taxes by default - on a line item level.
However, there is a setting in WooCommerce that resolves this by forcing WooCommerce to round on a subtotal level.
To turn this setting on, go to WooCommerce > Settings > Tax > Tax Options and then select the Round tax at a subtotal level check box.
