You ship the goods to your buyer.
You send us the shipping documents and collection instructions and we send these to your buyer’s bank.
The buyer’s bank then requests payment or an undertaking to pay from the buyer. Their bank will not release the documents until the buyer has either made payment or promised to do so at a later date agreed by you.
Payment is not made until after the goods are shipped - so you bear the risk while goods are in transit or storage until you receive payment or acceptance.
Banks involved in the transaction do not guarantee payment.
It's your responsibility to check the importer's credit status and reputation before agreeing to an export collection.
