The terms of payment are important for both the seller and the buyer.
For the seller, the best terms would be full payment cash at the time of sale. But the buyer would prefer to have the goods before making payment.
Importers and exporters are separated from each other by of miles. This adds to the difficulties of an agreement of payment. However, exporters and importers usually meet each other half-way and agree to payment by a Letter of Credit.
A letter of credit (L/C) is a banker’s guarantee that payment will be made, if all the required shipping documents are presented.
- In this way, exporters receive a guarantee not only from importers, but also from a bank.
- On hand, importers are given the guarantee that the bank will not make payment unless all the shipping documents are presented.
Nevertheless, the exporter can further require an letter of credit. That means the guarantee of payment cannot be cancelled either by the opening bank or the importer.
