Simply negotiate the collection terms with the importer, ship and then hand the documents to FNB with collection instructions
You would need to complete a Foreign Bills for Documentary Collection instruction form which must be handed to the bank together with documents
The bank would need the banking details of the importer
Discuss the transaction with the bank
If you request the documents to be released contrary to instructions, you will also be requested to sign an indemnity whereby the bank will be able to debit your account within 3 working days after release of the documents to your business. Discuss the transaction with the bank.
