Do not choose a channel. Assign each channel a job
My verdict is: use marketplaces for the commercial work they perform better, but do not let borrowed demand become the business model by accident. An established marketplace may shorten the path to a first order because buyers already search, compare and transact there. An owned store can explain the product, shape the buying journey and develop a direct customer relationship.
Do not compare marketplace fees with website platform fees alone. Include acquisition, fulfilment, returns, support, advertising, payments and repeat value.
The ACCC describes marketplaces as a relatively low-cost route into a market, while also noting that platforms can influence product ranking, collect substantial customer data and exercise considerable control over seller transactions. That is the real trade-off: immediate access versus long-term control.
Unlike deciding whether TikTok Shop is worth using or whether paid ads and SEO should work together, this question asks who controls the route to the next sale.
The Channel Ownership & Contribution Gate
Pass these six checks before opening a new channel or moving meaningful volume away from an existing one.
Relevant buyers exist
Does the channel contain suitable demand for this product, or only a large audience attracted by price and convenience?
The order remains valuable
After fees, advertising, fulfilment, returns and support, does the channel leave enough contribution?
Access supports the job
Can the business lawfully obtain the data, permission and service context needed for support and future value?
The offer survives comparison
Can buyers understand why the product is different, or will the channel flatten the decision into price and reviews?
Delivery is repeatable
Can inventory, fulfilment, returns, service levels and catalogue accuracy remain reliable across channels?
No single gatekeeper decides survival
Would a ranking, policy, fee or account change remove an unacceptable share of profitable demand?
Limited brand control may still suit replenishment products. An owned store without demand is infrastructure, not yet a growth engine.
Choose the channel role that matches the buying job
| Business reality | Primary role | Why it fits | Main risk |
|---|---|---|---|
| Known product with active category demand | Marketplace-led discovery | Reaches buyers already comparing available products | Price pressure and weak differentiation |
| Product needs education or configuration | Owned-store conversion | Controls explanation, proof and buying sequence | Paying for traffic before the journey converts |
| Repeat purchase creates much of the value | Owned relationship, marketplace acquisition | Uses external demand while building permissioned retention | Breaching platform or privacy rules when reconnecting |
| New product with uncertain demand | Limited marketplace test | Tests search, price and fulfilment with bounded exposure | Mistaking platform demand for brand demand |
| Demand is concentrated on one platform | Marketplace core plus resilience plan | Accepts commercial reality while reducing dependency | Prematurely forcing volume to a weaker owned route |
Amazon publishes separate plan and referral fees; eBay fees vary by store, category and jurisdiction. Owned commerce still carries payment, technology, support and acquisition costs.
Check local obligations. EU rules require marketplaces to collect specified trader information, while Australian consumer rights still apply to business sellers. Compliance, price accuracy and product safety are operating requirements.
The Discovery-to-Repeat-Value Evidence Loop
Evaluate each channel across the same customer journey. Platform revenue and website revenue are not comparable until definitions, maturity and cost treatment match.
Record demand origin
Separate marketplace search, paid media, organic discovery, direct demand and returning customers.
Measure suitable interest
Track the product, price, proof and comparison context that attracts the right buyer.
Capture collected value
Use actual orders, discounts, tax and cancellations rather than clicks or reported cart value.
Assign complete channel cost
Include fees, media, payment, delivery, storage, support, returns and damaged inventory.
Observe the next purchase
Compare repeat timing, retained contribution and permissioned relationship by first-order source.
Keep, change or exit
Fund the channel role that produces mature contribution without unacceptable dependency.
An owned website also creates additional discovery routes. Google supports Product structured data on product pages and Merchant Center feeds, including free listings where eligible. That does not guarantee visibility, but it means an owned store can participate in product discovery beyond paid traffic.

Compare the channels after fulfilment and repeat value
| 90-day cohort | Marketplace | Owned store |
|---|---|---|
| Collected first-order revenue | £92,000 | £68,000 |
| Product and fulfilment cost | £49,500 | £35,800 |
| Channel, payment and acquisition cost | £18,600 | £16,400 |
| Returns and service cost | £6,900 | £4,900 |
| First-order contribution | £17,000 | £10,900 |
| Contribution from repeat orders in window | £3,200 | £9,100 |
| Total observed contribution | £20,200 | £20,000 |
The figures are invented solely to demonstrate reconciliation. They exclude tax, fixed overhead, cash timing and purchases outside the observation window. Replace every line with your own definitions and records.
The marketplace produces more first-order contribution; the owned store produces stronger observed repeat value. Keep the marketplace focused on active category demand and improve the owned store’s acquisition economics before scaling it.
This avoids moving orders merely because visible website fees look lower—or accepting platform dependence merely because marketplace revenue is larger.
A 90-day channel-role test
Define roles and economics
Choose a product cohort. Map demand, fees, acquisition, fulfilment, returns, customer access and repeat-value rules for each channel.
Run a controlled split
Keep product, pricing and inventory rules stable enough to learn. Give each channel one explicit acquisition or retention job.
Reconcile mature outcomes
Compare fulfilled contribution, suitable customers, returns, repeat purchases, operating effort and dependency exposure.
Expand the marketplace role when it reaches profitable demand the owned store cannot efficiently acquire. Expand the owned route when education, bundles or repeat relationships create stronger mature value. Keep both when their jobs are complementary. Exit a channel only when its complete economics, risk or customer mismatch remains unacceptable after a fair test.

Frequently asked questions
Is it better to sell on a marketplace or your own website?
Neither is universally better. Marketplaces can provide faster access to existing buyer demand; an owned website provides more control over presentation, measurement and the customer journey. Compare fulfilled contribution, suitable demand, customer access, repeat value and operating effort.
Can a business sell on marketplaces and its own website at the same time?
Yes. The marketplace can acquire first-time buyers or test demand, while the owned store supports education, bundles, launches and repeat relationships. Give each channel a defined job and coordinate pricing, stock, fulfilment and measurement.
Are marketplace fees always more expensive than running a website?
No. Marketplace costs can include plans, referral fees, fulfilment, returns and advertising. An owned store has payment, technology, support and acquisition costs. Compare the full cost to acquire, fulfil and retain a customer.
Should a new brand start on a marketplace first?
A marketplace can test demand and operations when buyers already search there. Start with a limited product set and explicit learning goals. Build an owned destination early when brand explanation, repeat demand or customer education matter.
What should remain exclusive to an owned store?
Consider keeping education-heavy products, configurable bundles, subscriptions or launches on the owned store when the website can explain them better. Do not restrict a strong marketplace product merely to force traffic onto an unproven website.
Build one business, not two competing sales reports
Marketplaces provide buyer access; owned stores build control and repeat value. Give each channel a job and invest where complete customer economics justify the dependency.
