How to price products for multiple marketplaces (UK 2026) — fee-adjusted margins

Build channel scenarios from current account-specific fees and your own costs; do not rely on universal marketplace rankings or margin targets.

10 min readIntermediateUpdated 11 July 2026

TL;DR

Choose a target margin using your own overhead, returns, tax and risk requirements.
Enter current category, account, programme and contractual fees from primary sources.
Treat Temu's rate as unknown until it is supplied from the seller agreement.
Check each marketplace's current pricing and parity policies before publishing.
Review prices whenever costs, fees or commercial terms change.

Why this matters

Marketplace fees vary by category, account, programme, contract and date. A copied headline rate can produce a misleading margin comparison, especially when a contractual rate is unknown.

Goal of this playbook

Create a dated, channel-by-channel scenario using your own costs and verified fee inputs, with unknown rates excluded until supplied.

Before you start

You’ll need:

Accurate cost of goods per SKU (landed cost, including inbound shipping and duty)
Average shipping cost per SKU
A target margin approved for your own commercial model
Current fee evidence or contractual terms for each marketplace
Access to the illustrative Marketplace Fee Calculator

The playbook

Define your target margin

Commercial decision

Set a target using your own overhead, returns, tax treatment, financing and risk requirements. This guide does not prescribe a universal healthy margin.

Gross margin = (Net revenue - COGS) / Net revenue.
Net revenue = Sale price - all marketplace fees.
COGS should include shipping cost to the buyer.

Calculate the break-even sale price per channel using the fee calculator

Per-SKU review

Enter cost of goods, shipping and a rate verified for the relevant category, account and programme. A marketplace with an unknown contractual rate must remain excluded until that rate is entered.

Date each source and keep a link or contract reference.
Add charges outside the simplified calculator separately.

Set a documented per-channel scenario

Per-SKU review

Use observed conversion, fulfilment, returns and service costs from your own operation. Do not assign channel premiums from unsourced assumptions about buyer psychology.

Record the reason and evidence for each adjustment.
Keep assumptions editable rather than presenting them as benchmarks.

Check for price-parity risks

Policy review

Review the current pricing and parity policies in each marketplace's official seller documentation. Obtain professional advice where a policy or legal interpretation affects the decision.

Record the policy URL and review date.
Do not infer another marketplace's policy from Amazon's wording.

Implement price rules in your inventory platform

Configured workflow

Configure supported price records and validate the resulting marketplace values before enabling updates. Connector direction, timing, accepted fields and retries remain marketplace-specific.

Review when inputs change

Scheduled control

Repeat the review when marketplace fees, supplier costs, currency, shipping, tax treatment or commercial terms change.

Record the previous and replacement source.
Recalculate affected SKUs before publishing new values.

How to know it worked

After following every step, you should be able to verify these outcomes:

Representative SKUs have documented cost and fee evidence
Unknown contractual rates are excluded rather than treated as zero
Current marketplace pricing policies have been reviewed
Results use one consistent VAT and tax basis

Frequently asked questions

Can I legally price differently across marketplaces?+

Marketplace pricing and parity rules can change. Review each platform's current official seller policy and obtain advice for your circumstances rather than relying on this playbook for a legal conclusion.

What margin should I target for marketplace sales?+

There is no universal target. Set it from your own overhead, returns, financing, tax, service and risk requirements and have the commercial model reviewed appropriately.

Should Amazon always be my highest price?+

No universal channel ranking is valid. Use current category and programme fees, your own fulfilment costs and the marketplace's current pricing policy.

How does FBA change the pricing calculation?+

Use the current FBA fee preview or official schedule for the product's dimensions, weight, category and programme. The simplified marketplace calculator does not model all FBA, storage or fulfilment charges.

Do I need repricing software?+

That depends on your catalogue, competition, policy constraints and review controls. Verify any repricing capability and guardrails in a representative test; this guide makes no payback or universal product-capability claim.
