Abstract: Disclosed is a computer-implemented method of generating a service contract for a shipping product. The method comprises: receiving information indicative of a requested shipping product; verifying an availability of the requested shipping product by means of an electronic product catalogue; receiving a tariff corresponding to the requested shipping product from a tariff system; receiving cost information about a cost of the requested shipping product from the electronic catalogue system; providing a user interface for allowing an operator to determine a price proposal based on the received tariff and the received cost information; generating a service contract based on the determined price proposal.
