Glossary/Marketplace fees
What is marketplace fees?
Marketplace fees are the costs a platform charges on every order — commission (a percentage of revenue), transaction or payment fees, and seller-funded promotion costs (vouchers, free-shipping subsidies, platform-co-funded discounts). Fees vary by category, by program, and by campaign window.
01/Formula
Formula
Marketplace fees per order = Commission % + transaction fee + seller-funded promo costs
Example
A ฿1,000 Shopee order: 5% commission (฿50), 2% transaction fee (฿20), ฿30 free-shipping subsidy. Marketplace fees = ฿100 — 10% of revenue. If gross margin was 30%, fees just consumed a third of the margin before any ad cost is added.
02/Why it matters
The trap, in one paragraph.
Marketplace fees are typically the largest line item after COGS, but they are scattered across the platform dashboard and rarely shown together. Sellers who do not model them per order systematically overstate profit — sometimes by 5–10 percentage points of margin.
03/In DataGlass
How Marketplace fees is used in DataGlass.
DataGlass reconstructs marketplace fees on every order from platform data, so per-order economics and per-SKU contribution margin reflect the real cost of selling on Shopee today, with Lazada and TikTok Shop coming soon.
