eBay vs Amazon is one of the most common questions wholesale sellers ask when deciding where to build their business. Both platforms offer enormous sales potential for wholesale sellers — but they operate very differently, have different fee structures, different buyer behaviours and different competitive dynamics. Choosing the right platform — or the right combination of both — can significantly impact your margins, your workload and the long-term sustainability of your business.

We are Brandhunterz Ltd — a UK registered wholesale sourcing company (Company No: 15342697) — and we help wholesale sellers build profitable businesses on both platforms. In this complete comparison guide we break down every key difference between eBay and Amazon for wholesale sellers and give you a clear framework for deciding which platform is right for your situation.

Platform Overview — Amazon vs eBay by the Numbers

Metric	Amazon UK	eBay UK
Monthly unique visitors	300M+	130M+
Active buyers UK	30M+	20M+
Seller fees (approx)	25 to 35% total	13 to 16% total
Monthly seller fee	£34.99/month	From £25/month
Fulfilment option	FBA — hands free	Self-fulfilled or 3PL
Competition per product	Very high	Lower
Account setup complexity	High	Low
Gated categories	Many — approval needed	None for most categories

Fee Comparison — Where Your Money Actually Goes

The fee difference between Amazon and eBay is one of the most significant factors for wholesale sellers. Higher fees mean you need a higher selling price or a lower wholesale buy price to achieve the same profit margin. Here is a direct fee comparison on the same £14.99 product:

Fee	Amazon FBA	eBay
Referral / Final Value Fee	£1.20 (8%)	£1.92 (12.8%)
Fulfilment Fee	£2.10 (FBA)	£2.80 (postage)
Storage Fee	£0.10	£0.00
Monthly Subscription	£34.99/month	£25/month
Total Per Unit Cost	£3.40+	£4.72+

The Buy Box vs Best Match — How Each Platform Allocates Sales

One of the most important structural differences between Amazon and eBay for wholesale sellers is how each platform decides which seller gets the sale when multiple sellers offer the same product.

Amazon — The Buy Box System

On Amazon all sellers offering the same product share a single listing. Only one seller holds the Buy Box at any given moment — receiving the vast majority of sales. Buy Box allocation is based on fulfilment method, price, account health and stock availability. FBA sellers have a significant structural advantage. Use Keepa to analyse Buy Box history on any listing before deciding to sell on Amazon.

eBay — The Best Match System

On eBay every seller creates their own individual listing for the same product. eBay’s Best Match algorithm ranks listings based on relevance, price, seller feedback, handling time and listing quality. Unlike Amazon there is no single winner — multiple sellers can all appear in search results and all receive sales. This means eBay is structurally less winner-takes-all than Amazon and new sellers can compete more fairly from the start.

Factor	Amazon Buy Box	eBay Best Match
Sales distribution	Winner takes 80%+ of sales	Multiple sellers all receive sales
New seller disadvantage	High — history matters significantly	Low — listing quality matters more
Price competition	Critical on non-MAP listings	Important but not the only factor
Research tool	Keepa	Zik Analytics

Fulfilment — FBA vs Self-Fulfilment

Fulfilment is one of the biggest practical differences between selling on Amazon and eBay as a wholesale seller.

Amazon FBA — Hands-Free Fulfilment

Amazon FBA handles all picking, packing, shipping, customer service and returns on your behalf once your stock is in their warehouse. As your sales volume grows Amazon scales with you at no additional effort. The downside is the FBA fee structure — particularly for heavier or larger products — and storage fees that accumulate if stock moves slowly.

eBay — Self-Fulfilment

eBay sellers fulfil orders themselves — storing stock at home or in a warehouse, packing each order individually and booking couriers for each shipment. At low volumes this is manageable and keeps costs low. At higher volumes the time investment becomes significant and many growing eBay wholesale sellers transition to a third-party logistics provider — a 3PL warehouse that stores and ships on their behalf.

Volume Level	Amazon FBA	eBay Self-Fulfilment
1 to 20 orders/day	Excellent — fully hands free	Very manageable from home
20 to 50 orders/day	Excellent — no change needed	Manageable but time-consuming
50+ orders/day	Excellent — Amazon scales for you	Move to 3PL — home fulfilment unsustainable

Product Research — Different Tools for Different Platforms

Researching products for Amazon and eBay requires different approaches and different tools because the data you need is platform-specific.

Research Need	Amazon Tool	eBay Tool
Sales history and demand	Keepa	Zik Analytics
Fee and margin calculation	AMZScout or Helium 10	Zik Analytics built-in calculator
Sell-through rate	BSR and Keepa drops	Zik Analytics sell-through %
Competitor analysis	Helium 10	Zik Analytics competitor view

Account Setup and Requirements

Amazon — More Complex Setup

Amazon requires identity verification through a Know Your Customer process including government ID upload, bank statement submission and sometimes a video verification call. The process takes 1 to 5 business days. Some product categories require ungating — additional approval before you can sell certain brands or categories. The Professional Seller account costs £34.99 per month from day one.

eBay — Simpler and Faster Setup

eBay business account registration is significantly simpler — typically completed in under 30 minutes with no identity verification process required upfront. You can list and sell immediately after registration. The main limitation for new eBay sellers is selling limits — eBay restricts the number of items and total value new accounts can list per month until you build a positive selling history. These limits increase automatically as you build positive feedback.

Which Platform is Right for You?

The answer depends on your specific situation. Use this decision framework:

The Dual Platform Strategy — Maximum Revenue From Every Wholesale Account

The most commercially efficient approach for established wholesale sellers is to sell the same products on both Amazon and eBay simultaneously. This strategy extracts maximum revenue from every wholesale account without requiring additional supplier relationships — you simply split your stock order between Amazon FBA and eBay self-fulfilment.

Benefit	How it Works
Double revenue channels	Same wholesale product generates sales on two platforms
Higher order quantities	Larger orders unlock better wholesale pricing and terms
Platform risk diversification	Amazon account issue does not kill all revenue — eBay continues
Clearance channel	Slow-moving Amazon stock can be cleared on eBay
Stronger supplier relationship	Higher combined order volumes improve your standing with brands

Conclusion — Not Either Or But Both

The eBay vs Amazon debate is ultimately a false choice for established wholesale sellers. Both platforms serve different buyer segments, have different competitive dynamics and offer different advantages. The most successful wholesale sellers use both — starting on whichever platform best matches their starting capital and experience level and expanding to the other as their business grows.

Research every product for both platforms before ordering — use Keepa for Amazon demand and Zik Analytics for eBay demand. Validate all margins with AMZScout or Helium 10. And find verified wholesale brands for both channels through our Brands Directory.
