Erwin Boogert was so kind as to point out this article in The China Post that discusses a new B2B payment service by Citibank:
Citibank developed a customized implementation project to meet Maersk Taiwan Ltd's requirements by incorporating the advantages of Citibank's on-line banking and financial service. CitiConnect Online Service is part of Citibank's EBPP (Electronic Bill Presenting and Payment) architecture, which covers complete on-line solutions from presenting bills, managing disputes, and online payments.
Through the integration of CitiConnect Online Service and Maersk Sealand's e-commerce website, Maersk Sealand customers in Taiwan may pay from non-Citibank accounts and even release payments after banking hours to proceed with the printing of Bills of Lading.
