The final position on payment authorization should be confirmed by the person who actually bears responsibility for that step. The supplier provides account verification, payment terms, bank receipts, and milestone evidence; the importer then obtains sign-off by the responsible procurement, logistics, after-sales, or compliance lead. Multiple participants do not mean responsibility is dispersed. If nobody signs off, there is no clear stop point before funds are exposed ahead of verifiable delivery progress.
