In eZforex, affiliates have multiple reports. One such report is named Gross Profit Report (GPR). The GPR consists of multiple eZforex gross sales, such as client buy foreign currency, client buy foreign travelers cheques, as well as agency selling of foreign currency. The cost of sales is the actual cost of each category including inventory. The prior month's inventory is the first item, then the cost of sales is added to the remaining cost of sales items. Today's inventory is subtracted from the cost of sales category, thus leaving a total cost of sales, which is subtracted from the Gross Sales category of the GRR, leaving profit. Often affiliates confuse the differences between LPR and GPR.
