Definition
What is the FiveX glossary?
The FiveX glossary defines marketplace profitability, retail media and operational intelligence concepts so they can be reused consistently across frameworks, solutions and comparisons.
FiveX framework
Original marketplace intelligence frameworks
Marketplace Profitability Framework
A practical framework for moving from revenue and ad metrics to real marketplace contribution margin.
- Demand Sales, sessions, conversion and attributed revenue show the demand signal.
- Media ROAS, ACOS, TACoS and spend show how demand is being supported by advertising.
- Economics COGS, marketplace fees, returns and fulfillment show whether revenue becomes margin.
- Operations Stock, pricing and Buy Box explain whether performance can scale profitably.
Marketplace profitability is not a single metric. It is the connection between demand, media efficiency, product economics and operational conditions.
Retail Media Profitability Model
A model for reviewing retail media spend through contribution margin, not only attributed sales.
- Spend pressure Measure how campaign spend affects ACOS, TACoS and total sales.
- Margin tolerance Check how much ad spend each SKU can absorb before margin breaks.
- Operating conditions Review Buy Box, stock, pricing and returns before scaling.
- Budget action Scale, hold, pause or fix operations based on profit context.
Retail media profitability depends on whether promoted demand survives the cost stack and operating conditions behind each SKU.
