Replying to [Catalyst]:
This question is very relevant to me. But I can see why you have a problem for it. You can really compare L/C to TT - the question is really L/C vs. advance payment by TT.
I have asked my new manufacturer for L/C, while they have argued for advance payment by TT.
Obviously advance payment by TT is the best for the exporter, while open account by TT is best for the importer. In the middle lie bills for collection and L/C.
I choose L/C.
Advance payment by TT is too much of a risk to expect any buyer to bear (even if you have a contract, the costs of enforcing it internationaly would be prohibitive).
L/C is still better for an exporter than bills for collection.
If exporters complain about the length of time for payment of an L/C then I ask this; you wouldnt agree to an open account, so why expect me to agree to advance payment.
L/C balances the risk more fairly.
