iControl have requested we not provide a help topic on connecting with them as they want to provide this to you directly. You will therefore need to contact either the reseller or iControl directly.
HINTS ON UPLOADING iCONTROL SUPPLIER CARDS:
The file needs to be a CSV file with 2 columns
Below are the same CSV file, one viewed in Excel and the other in Notepad.
When you upload the file you need to say YES it has a header row and for the file format choose: '2 Columns - Card ID, Supplier Name' (if your file is displayed with Card ID in 1st column)
When uploaded you will only see the Supplier name, but the Card ID file is still there in the background to be used in the file export to iControl.
