The exception error can be seen to be triggered by Tax calculation for sales order and the method VERTEX::CalculateTaxes

Resolution

It is required to investigate vertex settings of the customer's Reseller in Billing > Settings > Taxation > Vertex > General.

If the reseller is configured to use vendor vertex settings, it is required to match the vertex configuration of Reseller's Provider inclusive of the Company Code.

In example : If Reseller L2 configuration Company Code is empty while Reseller's Provider which in this case is L1 have Company Code 9999, the error "Plug-in is not configured" can be triggered.

Reseller L2
