In order to maximize the throughput of net cash-in flows on the supply chains, the introduction of the latest methodologies of SCM is of essence not only to to the "arterial flows" of goods and services in the production and distribution but to the "venous flows" of money as well. This paper proposes that improvement of STP (Straight-Through Processing) of remittance data with structuring and international standardizing in payment messages plays the key role for the total optimization in the "venous flows" on the whole supply chain.
