After you have selected your file for upload, you will be prompted to identify what type of information each column contains using the drop downs options. Two of your customers will be displayed as an example - this is only to help you select the correct fields for each column. All customers in your file will be uploaded.
Please click here for a list of available data fields.
Every column must be identified. If you do not wish to include a column, please select Ignore.
This is a mandatory step, and the upload will not initiate until all fields are identified.
