We are in the process of starting to use Telpay to pay some of our vendors. I have setup Telpay and all seems to be working in Adagio so far. My issue is that in the vendor details EFT Tab there is a line for "GST/ID Number". I can't enter our GST number here as it is locked and I can't find where it populates from. I am assuming that this number is intended to go to our vendor somehow if it is on this screen? Is this required?
