Costs
Portbase is a non-profit organisation. Companies only pay a contribution for the use of services with a clearly demonstrable added value. When set off against the advantages, these costs are relatively small. The financing of services that are of particular strategic interest to the port is done using the general income of shareholders of the Port of Rotterdam Authority and the Port of Amsterdam. On the pages in this website listing the services, an indication is given for each service whether a contribution is charged or not.
Choice of two subscriptions
For each service, clients can choose between two different subscriptions:
- Portbase Basis Plus: a fixed amount per month and a payment per transaction;
- Portbase Basis: just a (somewhat higher) payment per transaction. This is especially attractive to clients who do not work through the Port Community System very often.
Invoicing
Invoicing is done on a monthly basis. For each client, Portbase makes as realistic as possible an estimate of the expected number of transactions. Settlement takes place once a year (similar to the invoicing method used by energy companies).
