Commission earned so far, in dollars. Not the number of sales. Running totals, straight off the CashNetwork report.
Enter the dollar totals to date, not what came in since last time and not a count of sales. Each save is stamped with today's date and the previous figures are kept, which is what builds the return curve.
Export the Source ID report as CSV and pick the file here. Set the export to cover at least 90 days, otherwise back end sales against older runs will be missing.
