Expedient can check that the User submitting the Payment has the appropriate authority for the value of the payment. The Payment levels are set in Administration > Company Details > Entry Payment Level.
If you cannot see this screen and want to set up Payment Authority levels please raise a ticket with Expedient Support.
Each User can be assigned to an Entry Payment level in the Users Masterfile.
Please note: The Payment Authority Amount is calculated from the total amount payable for the entry, it will not take into account previous payments/refunds for entry amendments.
Under the current Customs guidelines, Expedient cannot fully identify if GST will be payable or deferred.
Expedient performs the best calculation based on the defer GST flag in the Customer Masterfile so this could result in a differing amount being calculated.
Expedient does not calculate Wine Tax, Luxury Car Tax, Dumping Duty or Countervailing Duty so these could result in a differing amount being calculated and paid.
If the Payment Authority module is turned ON but no restriction is entered against a User then they will have unrestricted payment amounts (assuming they are a Broker OR been granted payment privileges as the User Option is on.)
