Members of trade exchanges must keep records that record and explain all business transactions and other acts they engage in that are relevant to a particular sale importation, purchase, dealing or entitlement. The records must be kept for five years after the completion of the transaction or acts to which they relate.
In addition to ordinary accounting documents, this may include invoices and receipts, as well as purchase orders, delivery dockets, contracts, barter scheme statements, and any other relevant documents.
The other relevant documents may include the application for membership of the bartering scheme, the rules of the scheme, and any other documents governing the relationships between members, and between members and the trade exchange.
