The original value (RRP) of all items sold before any discounts & deductions
Formula
Gross Merchandise Value = Sum (RRP) WHERE Payment Status IS NOT "Voided"
Explanation
Gross Merchandise Value is the sum of the RRP (Recommended Retail Price) of all items sold in a given period. Thus, it is before any deductions such as discounts, returns and taxes are made.
Due to that, it is not really a great measure of success as it can be easily inflated. It is still useful as a starting point in your P&L from which everything gets deducted.
