Gross Merchandise Value (GMV) is the total value of all merchandise sold through a platform or store over a given period, calculated at the full sale price before any deductions. For a Shopify brand, GMV is the sum of every order at checkout price - before subtracting returns, refunds, discounts, platform fees, or cost of goods. It is the broadest possible measure of transaction volume and the standard top-line metric used to communicate the scale of an e-commerce business.
The distinction between GMV and revenue matters significantly and is frequently misunderstood. GMV represents gross transaction value; revenue represents what the business actually retains after deductions. For a direct-to-consumer Shopify brand, the gap between GMV and net revenue is typically driven by returns and refunds (which reduce recognized revenue), wholesale or marketplace fees (if selling through third-party channels), and discounts applied at checkout. A brand reporting $10M GMV might have net revenue of $8.5M after a 10% return rate and platform fees. For marketplace businesses like Etsy or Amazon, the gap is even larger - GMV includes the full transaction value while revenue is only the fees the platform takes.
GMV is most useful as a scale metric and for year-over-year growth comparisons, but it is a poor indicator of business health on its own. A brand growing GMV rapidly through aggressive discounting or with a deteriorating return rate can show impressive GMV numbers while underlying profitability erodes. This is why sophisticated operators always pair GMV with metrics that capture quality: gross profit margin, contribution margin, net revenue, and repeat purchase rate. GMV tells you how big the business is; these metrics tell you whether it's healthy.
For Shopify brands raising investment or benchmarking against competitors, GMV is the common language - investors and industry reports almost universally use GMV as the primary scale comparison metric. Understanding exactly what your GMV includes and excludes, and being consistent in how you calculate it, is essential for credible financial reporting and fundraising conversations.
