The percentage or flat fee a selling platform charges on each transaction for providing access to its marketplace and customer base. Similar to a referral fee but used more broadly across platforms.
Understanding Platform Commission
A platform commission is the fee an ecommerce marketplace charges sellers for each transaction completed on its platform. Unlike subscription fees (which are fixed monthly charges), commissions are variable and scale with your sales volume — you pay more as you sell more.
Platform commissions go by different names on different marketplaces: "referral fee" on Amazon, "final value fee" on eBay, "transaction fee" on Etsy, and "payment processing fee" on Shopify. Despite the different names, they all serve the same purpose — compensating the platform for providing the marketplace infrastructure, customer traffic, and payment processing.
Commission rates vary significantly between platforms and product categories. Amazon charges 8-15%, eBay charges up to 15%, Etsy charges 6.5% plus payment processing, and Shopify charges only payment processing fees (no marketplace commission) because it's a storefront platform, not a marketplace.
Why It Matters for Ecommerce
Platform commissions are one of the largest variable costs for ecommerce sellers. Comparing effective commission rates across platforms helps you make strategic decisions about where to focus your selling efforts. A product that's profitable on Shopify (low commissions) might be unprofitable on Amazon (higher commissions but more traffic).
Practical Example
You sell a $60 product across three platforms. Amazon commission: $9.00 (15% referral). eBay commission: $7.80 (13% final value). Shopify commission: $2.04 (2.9% + $0.30 processing only). The same product generates $51, $52.20, or $57.96 in net revenue depending on the platform — a $6.96 spread that matters at volume.
