The real channel economics of eCommerce
Not all eCommerce revenue is equal. Amazon, DTC and wholesale each change margin, customer ownership, stock pressure, data access and operational complexity. Founders need channel-level economics, rather than top-line comparisons, to know where to invest.
The wrong way to think about channels is to ask which one has the highest revenue. The right way is to ask which mix creates the best blend of margin, customer ownership, cash generation and strategic value.
Each channel changes the equation.
The most mature brands do not choose channels emotionally. They model them properly — when Amazon is a useful starting point, when DTC should lead, when wholesale becomes attractive, and where the risk of cannibalisation starts to rise.
Often attractive because it is easy to start. The customers are already there, the logistics are familiar and the economics are more predictable.
But predictable does not mean generous. Amazon takes a large bite, competition is fierce, and the customer relationship belongs largely to Amazon — not to you.
- ● Demand already exists at scale
- ● Operationally simple to launch
- ● Predictable fee structure
- ● Can become a cash-cow at scale
- ● Crowded marketplace, weak data access
- ● Brand spend creates halo Amazon benefits from
- ● Pricing power belongs to the platform
- ● Customer list is not yours
Gives much stronger control over brand, email, customer data and lifetime value.
It also exposes the business to paid-media volatility and attribution noise. Founders sometimes feel richer on DTC right until Meta or Google becomes more expensive and the spread narrows sharply.
- ● Best customer data and LTV insight
- ● Stronger brand building and pricing
- ● Bundles, repeat-purchase, subscriptions
- ● Direct relationship + email/SMS
- ● Paid media is expensive and volatile
- ● Attribution is messy at scale
- ● Profitability hides upstream of CAC
- ● Needs real creative + retention skill
Can look ugly on paper because of the discount to RRP. Yet at scale it can be one of the best channels in the mix.
Large wholesale orders move volume with relatively low channel overhead and put the brand in front of new customers. Small-scale wholesale, by contrast, is often messy and admin-heavy.
- ● Highly scalable at meaningful order sizes
- ● Low overhead per unit at volume
- ● Incremental distribution + reach
- ● Strong brand placement opportunity
- ● Margin-dilutive on paper vs RRP
- ● Channel conflict if mismanaged
- ● Small-scale wholesale is admin-heavy
- ● Risk of partner price erosion

That is why channel-level P&L visibility matters
Without it, founders can be busy in three places and profitable in none.
“The managerial challenge is stock and channel conflict. Mature channel strategy is not about adding revenue streams indiscriminately — it is about building a coherent route-to-market system.”
Founders need to know when Amazon is cannibalising DTC, when DTC brand spend is lifting Amazon indirectly, when a wholesale partner is eroding price perception, and when one channel is starving another of stock.
Channel economics in eCommerce
Different channels create different margin, cash and data dynamics. Use this table to triangulate the trade-offs before you re-cut your mix.
| Channel | ▲ Strength | △ Watch-out |
|---|---|---|
Amazon Marketplace · 3P or 1P | Easy demand access, operationally simple start, predictable fee structure, can become a cash-cow channel at scale. | Crowded marketplace, weak customer ownership, brand spend elsewhere can create a halo Amazon benefits from. |
DTC website Owned · Shopify / Centra / WC | Best customer data, stronger brand building, better control over pricing, bundles and repeat-purchase flows. | Paid media is expensive, attribution is messy, and scaling traffic profitably takes real skill. |
Wholesale / retail B2B · key accounts + indies | Highly scalable with lower channel overhead at meaningful order sizes; incremental distribution and brand reach. | Margin-dilutive on paper, can create channel conflict, and small-scale wholesale is noisy to operate. |

It depends on what you are short of — cash, data or distribution. Amazon is usually the fastest route to revenue with the lowest setup cost, so it suits brands that need to validate demand and generate working capital quickly.
DTC is the right starting point if you need to learn who your customer is, what they pay for, and how often they come back. Wholesale only makes sense once you have a tested product, predictable supply and the margin headroom to take a 40–55% discount to RRP.
Look at three signals together: search-brand traffic on DTC vs branded search clicks on Amazon, repeat-purchase rate on DTC for SKUs also listed on Amazon, and the gap between blended CAC and DTC contribution margin.
When DTC paid media costs are rising but Amazon revenue keeps climbing for the same SKUs, you are likely paying to acquire customers who buy on Amazon — the classic “halo into the wrong basket” pattern.
Revenue net of discounts and returns by channel, then directly attributable COGS (including platform-specific packaging or freight), platform fees (Amazon referral, FBA, ads — broken out), and channel-specific marketing and people cost.
The point is to land at a contribution margin per channel that survives scrutiny. If the same overhead is allocated three different ways across channels, the comparison is meaningless.
Yes — when order sizes are large enough that channel overhead per unit drops below 5% and the channel is genuinely incremental rather than substitutional. A 35% wholesale margin on a £150k PO with no marketing cost beats a 65% DTC margin paid for with £45k of Meta spend.
The trap is small-scale wholesale: 20 invoices a month, bespoke terms, sample requests, returns admin. That tends to lose money even when the line-item margin looks healthy.
Monthly, with a quarterly strategic review. Monthly catches drift — a creeping Amazon ACoS, a falling DTC repeat rate, a slipping wholesale partner. The quarterly review asks the harder question: is the channel mix still the right one for the next 12 months?
