Selling Through Marketplaces? Legal Risks You Didn’t Expect
New sales channels bring new revenue - and new legal exposure.
• 14 Nov 25
"Marketplaces are rocket fuel for sales - but if you don’t read the fine print, they’ll burn your business on re-entry." - Matthew Glynn
Introduction
Selling through platforms like Amazon, Shopify, Etsy, or app stores can supercharge your startup’s reach - but it also exposes you to legal risks that most founders never see coming. From platform terms to consumer protection laws, the rules of engagement are different - and unforgiving. If you don’t understand the legal framework, you could lose revenue, IP, or even access to your own customers.
In this blog, we’ll flag up some considerations to help you better prepare to tackle this issue - because prevention is always better than the cure. Legal issues are important but easily overlooked as founders focus on the big launch or are otherwise distracted by the issue of the day - and in a startup, there’s always an issue of the day.
Why this topic is important
This can be an important issue for start-ups because:
◼️Platform Terms: Marketplaces impose strict rules that override your own policies.
◼️IP Ownership: You may lose control over branding, listings, or product content.
◼️Consumer Protection: Refunds, warranties, and disclosures must meet legal standards.
◼️Jurisdictional Reach: Selling globally means complying with multiple legal systems.
◼️Tax Obligations: Platforms may trigger VAT, GST, or sales tax liabilities.
◼️Data Access: You may not own or control customer data.
◼️Dispute Resolution: Platforms often dictate how and where disputes are resolved.
◼️Product Liability: You’re still liable for harm caused by your product - even if sold via a third party.
◼️Account Suspension: Violating terms can lead to sudden takedowns or bans.
◼️Investor Scrutiny: Marketplace dependency and legal exposure are key due diligence items.
Q: Can I be sued for a product sold through Amazon or Shopify?
A: Yes - even if the platform handles logistics, you’re still legally responsible for the product and its impact.
Consequences of not addressing these issues
The consequences of not attending to this issue may include the following:
1. Legal Implications
◼️Contract Breaches: Violating platform terms can lead to account suspension or legal action.
◼️IP Disputes: Platforms may claim rights over your content or branding.
◼️Consumer Claims: You may face lawsuits over product defects or misleading listings.
2. Commercial Implications
◼️Revenue Loss: Account bans or chargebacks can wipe out income overnight.
◼️Brand Damage: Negative reviews or disputes can harm your reputation.
◼️Lost Control: Platforms may limit pricing, promotions, or customer communication.
3. Operational Implications
◼️Fulfilment Disruption: Platform logistics failures can delay orders and damage trust.
◼️Support Overload: Legal issues can trigger customer service chaos.
4. Biz Valuation Issues
◼️Investor Red Flags: Over-reliance on marketplaces with poor legal controls can reduce valuation.
◼️Exit Risk: Acquirers may avoid startups with unresolved platform liabilities.
These are indicative issues - the relevance of which will depend on your circumstances including the nature of business undertaken by your start-up.
What you need to be doing
We have identified quite a number of potential issues that the start-up needs to consider and below are some examples of the types of steps you might want to consider taking to address these issues considered above.
Review Platform Terms Thoroughly
Understand the legal obligations imposed by each marketplace.
Identify clauses on IP, refunds, data, and dispute resolution.
Protect Your IP
Register trademarks and copyrights before listing products.
Monitor for unauthorised use or counterfeit listings.
Localise Product Listings
Ensure descriptions, claims, and disclosures comply with local consumer laws.
Avoid misleading or unsubstantiated marketing language.
Secure Product Liability Insurance
Cover risks associated with third-party sales and global distribution.
Review exclusions and coverage limits.
Manage Customer Data Carefully
Understand what data you can access and how you’re allowed to use it.
Ensure compliance with privacy laws and platform policies.
Prepare for Account Suspension
Have contingency plans for alternative sales channels.
Document compliance efforts to support appeals.
The above suggestions are just a few of the steps you can consider taking. There are many more things that need to be done to ensure the associated risks are effectively and pragmatically dealt with.
Q: Can a platform like Amazon suspend my account without warning?
A: Yes - most platforms reserve the right to suspend or terminate accounts for any breach of their terms.
How these risks can play out
The Amazon Ban That Killed Revenue
A startup selling eco-friendly home goods was banned from Amazon for violating packaging rules. Overnight, they lost 80% of their revenue and spent 3 months trying to appeal - with no success.
The IP That Got Hijacked
A fashion startup listed products on a marketplace without registering trademarks. A competitor copied their listings and registered the brand - locking them out of their own name.
The Refund Avalanche
A startup launched a new gadget via Shopify but didn’t localise its refund policy. EU customers demanded refunds under consumer law - costing $60K in chargebacks and legal fees.
Frequently Asked Questions
Q: Do I need separate terms of sale for marketplace products?
A: Often yes - platform terms may override your own, but you should still define your policies clearly.
Q: Can I control pricing on marketplaces?
A: Sometimes - but platforms may impose minimums, maximums, or promotional restrictions.
Q: Is selling on marketplaces considered international trade?
A: Yes - and it may trigger tax, customs, and legal obligations in other jurisdictions.
