How to Start Selling on Amazon, Etsy, and eBay as a Small Business

Online marketplaces offer small businesses something that is difficult to achieve on your own: instant access to millions of active shoppers. Amazon, Etsy, and eBay each attract hundreds of millions of visitors every month, and those visitors arrive with credit cards ready and purchase intent high. For small businesses, selling on marketplaces can generate revenue while you build your own brand and website traffic.

But marketplaces also come with significant trade-offs: fees that eat into margins, competition that drives prices down, and platform rules that can change without warning. This guide helps you understand each platform, weigh the pros and cons, and decide which marketplaces (if any) make sense for your business.

Why Sell on Marketplaces

The primary reason to sell on marketplaces is traffic. Building an audience for your own website takes time, money, and consistent effort. A new online store might get a handful of visitors per day during its first months. Meanwhile, Amazon gets over two billion visits per month. Etsy gets over four hundred million. Listing your products on these platforms puts them in front of shoppers who are actively looking to buy.

Lower customer acquisition costs. When a customer finds your product through an Amazon search, you did not pay for the ad that brought them there. The marketplace did the marketing. Your "cost" is the referral fee, which is often lower than the cost of acquiring that same customer through paid advertising on Google or social media.

Built-in trust. Many consumers are more comfortable buying from a marketplace than from an unfamiliar website. Amazon's return policy, buyer protection, and familiar checkout process reduce purchasing hesitation. This trust factor is especially valuable for new businesses without an established reputation.

Testing and validation. Marketplaces are excellent testing grounds. Before investing heavily in inventory for your own store, you can list products on a marketplace to gauge demand, test pricing, and learn which products resonate with customers.

Amazon for Small Businesses

Amazon is the largest e-commerce marketplace in the United States, accounting for nearly 40% of all online retail sales. Selling on Amazon gives you access to an enormous customer base, but the competition is fierce and the fees are substantial.

Getting Started on Amazon

You have two selling plan options. The Individual plan costs $0.99 per item sold (plus referral fees) and is designed for sellers with fewer than forty items per month. The Professional plan costs $39.99 per month (plus referral fees) and includes access to advertising, bulk listing tools, and eligibility for the Buy Box.

Referral fees vary by category but typically range from 8% to 15% of the sale price. For most product categories, the referral fee is 15%. On top of that, if you use Fulfillment by Amazon (FBA), you will pay fulfillment fees based on the product's size and weight, plus monthly storage fees.

Fulfillment by Amazon (FBA)

FBA is Amazon's fulfillment service where you send your inventory to Amazon's warehouses, and they handle picking, packing, shipping, and customer service. Products fulfilled by Amazon are eligible for Prime shipping, which significantly increases visibility and conversion rates.

The trade-off is cost. FBA fees include per-unit fulfillment fees (starting around three to four dollars for standard-size items), monthly storage fees (roughly eighty-seven cents per cubic foot from January through September, higher during Q4), and potential long-term storage fees for slow-moving inventory.

Tips for Success on Amazon

Win the Buy Box. On product listings with multiple sellers, Amazon's algorithm determines which seller appears in the prominent "Buy Box." Factors include price, fulfillment method (FBA sellers have an advantage), seller rating, and shipping speed. Winning the Buy Box dramatically increases your sales.

Invest in product photography and A+ Content. Amazon's A+ Content (available to brand-registered sellers) lets you create enhanced product descriptions with rich images and formatted text. This can increase conversion rates by 5% to 10%.

Manage reviews proactively. Product reviews are critical on Amazon. Use Amazon's "Request a Review" button to follow up with buyers, and address negative reviews promptly and professionally.

Etsy for Handmade and Creative Products

Etsy is the go-to marketplace for handmade items, vintage goods, and craft supplies. With over ninety million active buyers, Etsy provides a curated marketplace where customers specifically seek unique, artisanal products.

Getting Started on Etsy

Listing fees are $0.20 per item for a four-month listing period. When an item sells, Etsy charges a 6.5% transaction fee on the total order amount (including shipping) plus a payment processing fee of 3% plus $0.25.

Setting up an Etsy shop is straightforward. You create a shop name, add your branding, write shop policies, and start listing products. Etsy's interface is designed for individual sellers and small businesses, making it one of the easiest marketplaces to get started on.

Tips for Success on Etsy

Master Etsy SEO. Etsy's search algorithm considers listing titles, tags (you get thirteen per listing), categories, and attributes. Use all thirteen tags and include long-tail keywords that match how buyers search. "Personalized leather journal for men" will outperform "journal" in Etsy search.

Tell your story. Etsy buyers value the maker's story. Use your shop's "About" section and product descriptions to share who you are, how you make your products, and what makes them special. Authenticity sells on Etsy.

Offer customization. Personalized and customizable products perform exceptionally well on Etsy. Engraved jewelry, monogrammed gifts, and custom artwork command higher prices and generate more engagement.

Use Etsy Ads strategically. Etsy's advertising platform lets you promote listings within Etsy search results. Start with a small daily budget (one to five dollars) and let it run for at least two weeks before evaluating performance.

eBay for General Merchandise

eBay has evolved far beyond its auction roots. Today, over 80% of eBay transactions are fixed-price "Buy It Now" listings. eBay is particularly strong for electronics, collectibles, automotive parts, refurbished goods, and brand-name products.

Getting Started on eBay

eBay offers a basic selling option with no monthly fee (you get up to 250 free listings per month) and a Store subscription starting at $4.95 per month for additional features and lower fees. The final value fee (eBay's commission) varies by category, typically 10% to 13.25% of the total amount including shipping.

Tips for Success on eBay

Use promoted listings. eBay's promoted listings feature lets you boost visibility by paying an additional percentage of the sale price if the item sells through a promoted click. Start with a 2% to 5% ad rate and adjust based on results.

Offer free shipping. eBay's search algorithm favors listings with free shipping. Build the shipping cost into your item price to take advantage of this boost.

Maintain your seller rating. eBay's Top Rated Seller status (achieved through consistent positive feedback and on-time shipping) gives you a discount on final value fees and a badge that increases buyer confidence.

Write detailed condition descriptions. Especially for used or refurbished items, be transparent about the condition. Detailed, honest descriptions reduce returns and negative feedback.

Fees and Margins: The Real Numbers

Understanding the true cost of marketplace selling is essential for pricing your products profitably. Here is a simplified breakdown for a $50 product.

On Amazon (with FBA): $50 sale price minus $7.50 referral fee (15%) minus $4.75 FBA fulfillment fee minus approximately $0.87 monthly storage fee equals roughly $36.88 in your pocket before product cost.

On Etsy: $50 sale price minus $3.25 transaction fee (6.5%) minus $1.75 payment processing (3% plus $0.25) minus $0.20 listing fee equals roughly $44.80 before product cost.

On eBay: $50 sale price minus $6.63 final value fee (approximately 13.25%) minus payment processing (managed payments, included in final value fee) equals roughly $43.37 before product cost.

These numbers vary by category, product size, and specific circumstances, but they illustrate an important point. Marketplace fees are significant, and you must factor them into your pricing strategy. A product that is profitable on your own website may lose money on Amazon after all fees are accounted for.

Managing Inventory Across Channels

Selling on multiple marketplaces (and your own website) creates an inventory management challenge. If you sell your last unit on Amazon but it is still listed as available on Etsy, you face an oversell situation that results in cancelled orders, negative reviews, and potential account penalties.

Use inventory management software. Tools like Sellbrite, Listing Mirror, and Linnworks sync inventory across multiple platforms in real time. When a sale happens on one channel, the inventory count updates across all channels automatically.

Maintain a safety buffer. Even with inventory software, keep a small buffer to account for sync delays. If you have ten units, list nine as available across all channels.

Track performance by channel. Understanding which products sell best on which platform helps you allocate inventory strategically. A product that flies on Etsy but barely moves on Amazon should have more inventory allocated to Etsy.

When to Focus on Your Own Store Instead

Marketplaces are valuable, but they should not be your only sales channel. Here is when to prioritize your own website.

When you want to build a brand. Marketplace sales do not build brand recognition. Customers remember they "bought it on Amazon," not the name of your shop. Your own store lets you create a brand experience and build a direct relationship with customers.

When margins are tight. If marketplace fees make your products unprofitable, selling through your own website with lower payment processing costs (typically 2.9% plus thirty cents) preserves your margins.

When you want customer data. Marketplaces own the customer relationship. You cannot email Amazon customers, retarget Etsy buyers with ads, or build a mailing list from marketplace sales. Your own website gives you direct access to customer data for email marketing and remarketing.

When you have established demand. If customers are already searching for your brand or products by name, an owned website captures that demand without paying marketplace fees.

The ideal strategy for most small businesses is a combination: use marketplaces for discovery and volume while building your own website for brand equity and long-term customer relationships. Start where the customers are (marketplaces), then gradually shift your focus to your own store as your brand gains traction.

Getting Started Today

If you are new to marketplace selling, start with one platform. Choose the one that best matches your product category and target customer. Create five to ten polished listings, focusing on quality photography and compelling descriptions. Monitor your results for sixty to ninety days, then decide whether to expand to additional platforms or double down on what is working.

Marketplace selling is not a set-it-and-forget-it strategy. It requires ongoing attention to inventory, pricing, customer service, and platform-specific optimization. But for small businesses looking to reach new customers and generate revenue quickly, it remains one of the most effective channels available.
