Acquisition dependence
Paid search and social are the main sources of new customers, and rising ad prices can push contribution negative on first orders.
E-COMMERCE & MARKETPLACES / STRATEGY + OPERATIONS
Growth is easy to buy and hard to make profitable
E-commerce companies sell products online through their own sites, apps and third-party marketplaces, while marketplace operators earn take rates, advertising and service fees from the sellers they host. For online sellers, contribution per order after product cost, shipping, returns, payment fees and acquisition spend is what separates scale from losses.

HOW THE BUSINESS WORKS
How e-commerce & marketplaces companies make money.
The revenue streams and structural traits that decide where profit is made and lost in this sector.
Revenue model
- Product sales through owned websites and apps
- Sales through Amazon, Walmart Marketplace, TikTok Shop and other marketplaces
- Marketplace take rates, seller advertising and fulfillment fees
- Subscriptions and memberships for replenishment or free shipping
Fulfillment cost
Pick, pack, postage and packaging are paid on every order, so average order value and shipping thresholds drive contribution.
Returns
Returns cost shipping both ways, handling and lost resale value, and in some categories they consume a large slice of gross margin.
Platform fees
Marketplace referral, fulfillment, storage and advertising fees stack up and change often, shifting which channel is profitable.
WHAT TO WATCH
The measures and pressures that matter now.
Five numbers management should review every month, and what is changing in the sector.
- 1
Contribution margin per order
Shows what each order earns after product, fulfillment, payment fees, returns and marketing.
- 2
CAC payback by cohort
Reveals whether new customers repay acquisition spend within the planning horizon.
- 3
Repeat purchase rate
Repeat orders carry little acquisition cost and decide whether a brand can scale profitably.
- 4
Return rate and recovery value
Tracks how much returned product can be resold, and at what cost.
- 5
Marketplace fee load
Total fees as a share of marketplace revenue shows whether a channel is still worth selling in.
Pressures right now
- Closing the de minimis exemption has raised the cost of cross-border fulfillment and narrowed the price advantage of China-based platforms.
- Marketplace fee changes, including inbound placement and low-inventory fees, keep shifting the economics of selling through Amazon.
- AI shopping assistants and agent-based checkout are starting to change how products are discovered and compared, with unclear effects on paid search.
- Paid social and search costs remain high relative to conversion, pushing brands to rebuild around retention and owned channels.

Workflow automation & AI agentsQuestions leaders in e-commerce & marketplaces should be able to answer
- What is our contribution per order by channel after every fee, return and acquisition dollar?
- How much paid-media revenue would we lose if we cut spend, and how do we know?
- Should we push more volume through marketplaces or pull it back to our own site?
