Yes.

The Shipping Verification APIs support both SalesInvoice and ReturnInvoice document types. If either type is registered, positive amounts will increase tracked volume metrics and negative amounts will decrease them. In addition, edits to previously registered transactions of any type will need to be re-registered to pick up any changes and adjust volume metrics appropriately.

Creating returns for beverage alcohol transactions is similar to creating a new sale. Use the CreateTransaction API with a document type of ReturnInvoice instead of SalesInvoice, and use a negative value for the dollar amount. After the return is created, you can call VerifyShipment and RegisterShipment, or call RegisterShipmentIfCompliant. You will still need to register return invoices so that volume metrics are adjusted.
