Thank you for the help, especially mrploddy
Showed the bank staff your post and they assisted me in transferring the funds.
My supplier has also verified that they have received it on the same day.
As to the question as to why I don't want my customer to pay my supplier is that
if I allow that to happen, I will be eating grass everyday.
Nonetheless, the supplier and client in this particular instance handle different products.
Thank you very much!
