Do Refund Orders automatically Void in ShipCompliant?

Refunding an order does not void the original transaction in ShipCompliant. When a refund is performed in Commerce7, another order will be sent to ShipCompliant. The refund order will have a negative value and negative quantity to offset the values from the original order. 

For Fulfillment 

If you are using ShipCompliant to push order information to a Fulfillment House, you will need to manually delete the fulfillment order in your fulfillment system.

For Taxation

Your refund order will be reported on the day the refund is processed. For example, a person buys a bottle in June and you issue a full refund in July. You should remit the tax in June and claim a credit in July.
