Successfully Making International Wire Payments Firms can often have difficulties making international wires to their foreign suppliers work properly. The wiring instructions provided to banks must be exact for these wires to work correctly. Inaccurate or incomplete wiring instructions can be very frustrating for accounting and treasury personnel who can waste a lot of time emailing questions and waiting for answers.
Vendors become unhappy and often refuse to provide further products or services.
It is important to revent the rejection of international wires up front because banks can take up to two weeks to research what has happened to a lost wire. Meanwhile, confusion reigns as to whether to send a replacement wire. Handwritten wiring instructions should not be accepted. It is too easy to make errors. Non-Western language handwriting can be quite different from European or American.
