It’s used by more than 250 million verified shoppers worldwide. When customers buy your products on the Shop app, orders are processed through your connected Shopify store. There are no seller fees besides standard payment [processing fees](https://www.shopify.com/blog/credit-card-processing-fees), which can reduce costs compared with other fee-based platforms. The app includes several features intended to encourage purchases from new and existing customers, like personalized recommendations and AI shopping assistants. Customers can also create collections of products they’re interested in and share their collections with other users. The Shop app also includes [Shop Cash](https://help.shop.app/en/shop/shop-cash)—a [rewards program](https://www.shopify.com/blog/small-business-rewards-program) that lets buyers earn virtual cash when they use the Shop app—and detailed shipment tracking.

Over the years, eBay has evolved to support Buy It Now listings and a mobile app with [135 million](https://investors.ebayinc.com/fast-facts/default.aspx) active buyers worldwide. Thanks to its history as an auction site, eBay attracts sellers in niche markets like antiques, collectibles, and electronics—but you can sell almost any new or used item on the platform, through [dropshipping](https://www.shopify.com/blog/ebay-dropshipping) or otherwise. The mobile app lets sellers create listings from a phone. eBay is similar to other online marketplaces for secondhand goods like Mercari and Whatnot, which also have a wide variety of items available across product categories. #### Who it’s for Antique and collectible dealers #### Pricing eBay charges several types of fees: - **Insertion fees.** If you list more than 250 products per month, you’ll pay a 35¢ listing fee per product.

You’ll also pay a fixed dollar amount: 30¢ if your product is less than $10, and 40¢ if your product is more than $10. - **eBay store subscriptions.** Although you can [sell on eBay](https://www.shopify.com/blog/sell-on-ebay) for free, creating an eBay store can reduce listing and selling fees and add [branding](https://www.shopify.com/blog/what-is-branding) to your storefront. Plans start at $4.95 per month. #### Features - Auctions and fixed-price listings - Shopify integration available through [Marketplace Connect app](https://apps.shopify.com/marketplace-connect) - Customizable storefront available through paid subscription ### 3\. Facebook Marketplace [Facebook Marketplace](https://www.shopify.com/blog/sell-on-facebook) is an online marketplace available to anyone with a Facebook account who meets parent company Meta’s [Commerce Policies](https://www.facebook.com/policies_center/commerce/). It doesn’t have its own dedicated app, but you can access it through Facebook’s main app. Marketplace is used as a consumer-to-consumer selling tool. Similar to OfferUp and Craigslist, you can sell items locally. Communication with potential buyers happens through Facebook Messenger. You can set boundaries for where you’re willing to sell, making Facebook Marketplace useful for offloading furniture, fitness equipment, televisions, or other heavy, hard-to-ship items. The platform also has some features geared toward small businesses, like in-platform checkout and shipping options. #### Who it’s for Local sellers in product categories like baby items, home furnishings, and clothing #### Pricing For shipped products, you’ll pay a 10% selling fee (or a minimum charge of 80¢). You won’t pay a fee for in-person, local sales. No listing fees apply. #### Features - In-app messaging with Facebook Messenger - Shipping and online checkout available - In-app checkout accepts major credit and debit cards and PayPal ### 4\. Poshmark [Poshmark](https://www.shopify.com/blog/make-money-on-poshmark) is an app best known for its wide selection of secondhand clothing and accessories—similar to Depop, Mercari, and ThredUp. More than [350 million items](https://poshmark.com/about) have been sold through the app since its formation in 2011.

It’s growing 2.7 times faster than the overall global apparel market. Poshmark has several features that can help you sell. Try out Poshmark Shows, which are livestreams that let you sell products in real time, or Posh Bundle, which encourages buyers to purchase multiple items from your storefront in exchange for discounts and reduced shipping costs. After you sell an item, Poshmark sends you printable shipping labels with the relevant shipping information. Buyers pay a flat-rate shipping charge of $6.49 on Poshmark. One downside is that Poshmark’s selling fees can be higher than comparable platforms. It takes a 20% commission on the order value for items over $15. #### Who it’s for Clothing resellers #### Pricing Poshmark’s selling fees depend on the value of your product: - **Products under $15:** Flat fee of $2.95 - **Products over $15:** 20% of the order value #### Features - Live selling through Posh Shows - Posh Bundle to encourage [cross-selling](https://www.shopify.com/blog/what-is-cross-selling) - In-app payment gateway accepts popular payment methods ### 5\.

It launched in 2011 with the mission of giving apparel a longer life.

The app lets shoppers browse a wide range of goods including secondhand clothing, beauty products, electronics, and office supplies. Mercari is similar to eBay and Depop in that you can sell clothing through the app. Depending on the product category, you might secure a lower selling fee with Mercari than with eBay. For women’s clothing and accessories under $2,000, for example, you’ll pay 10% with Mercari versus 15% in final value fees on eBay.

It lists [50,000 new products](https://www.thredup.com/about) daily. Instead of creating your own listings, you’ll send your products to ThredUp, and the company will photograph, list, and ship your products for you. The company says it normally takes four to eight weeks for products to start selling. ThredUp sets product prices (although you can make small changes once they’re listed), and the amount you earn depends on the product’s selling price. To earn money on your product’s sale, the product must sell within its listing window (between 30 and 90 days). After your product has been live on the site for a while, ThredUp will discount it to encourage sales. #### Who it’s for Clothing consignors #### Pricing ThredUp charges a $14.99 service fee for each 30-pound bag of clothing ($34.99 for premium bags).

The site receives 108 million visits per month, according to [Similarweb’s 2026 data](https://www.similarweb.com/website/craigslist.org/#overview). It features categories such as résumés, community, for sale, housing, services, jobs, and gigs, where participants can post sublets, cars for sale, personal classifieds, and even lost keys. While Craigslist has retained its retro interface, it does have an app that lets buyers and sellers use the platform from their phones—similar to Facebook Marketplace and OfferUp. Craigslist doesn’t have shipping functionality. You have to arrange payment and fulfillment directly with buyers. #### Who it’s for Local sellers #### Pricing Craigslist doesn’t have selling fees, and you won’t pay to post on the platform in most cases. There are a few [exceptions](https://www.craigslist.org/about/help/posting_fees), mostly for landlords, car dealers, and job postings. #### Features - No selling fees - Wide range of accepted posts ## How to choose the right selling app 1. [Consider your audience](#11) 2. [Research the fee structure](#12) 3. [Explore features](#13) 4. [Think about growth](#14) Consider these factors when choosing an app for selling items online: ### 1\. Consider your audience Identify your product’s [target audience](https://www.shopify.com/blog/target-audience), then research which selling apps align with your market. For example, Poshmark is used by fashion lovers, whereas Whatnot and eBay Live let you reach shoppers who buy through livestreams. Decide whether your items are better suited for local buyers or customers outside your location. If you plan to sell furniture, for example, you may choose a platform like Facebook Marketplace, which facilitates local pickups. If you’re selling a unique pair of shoes, on the other hand, an online selling app like Shop lets you reach customers all over the world. Finally, think about how quickly you want access to any money you’ve made. Local marketplaces let you connect with buyers in-person where you can accept cash instantly, while digital selling apps like [ThredUp take 15 days](https://help.thredup.com/en_us/can-you-explain-how-i-get-paid-out-HJoArZeon) to process payouts. ### 2\. Research the fee structure Each app has its own fee structure. Some platforms charge different fees depending on the product category, while others—including Shop—don’t charge seller fees at all. Also think about the convenience factor. A platform like ThredUp charges higher fees than other platforms, but it photographs, lists, and ships your products. This makes ThredUp a good choice to [make money online for beginners](https://www.shopify.com/blog/make-money-online-for-beginners), since you don’t need to take photos, write product descriptions, or price items yourself. ### 3\. Explore features As you compare platforms, think about which features you’ll need both now and in the future. Different apps offer unique features, like multiple payment methods, accelerated checkout, quick cash deposits, and in-app messaging. For example: - **eBay:** Has auction features that let you set your lowest price and have customers bid against each other. - **Poshmark:** Includes cross-selling tools with Posh Bundles, and Posh Stories, which lets you showcase your products in short videos similar to Instagram, TikTok, or Snapchat. - **Whatnot and eBay:** Support live selling if you want real-time interaction with buyers. - **ThredUp:** Uses a consignment model where you ship products to them to sell. - **Craigslist:** Offers fewer built-in seller tools. ### 4\. Think about growth If you’re looking to [make money online](https://www.shopify.com/blog/make-money-online) by cleaning out your closet or selling your old electronics, you might not care about [building a brand](https://www.shopify.com/blog/how-to-build-a-brand). But if you’re considering turning a [side hustle](https://www.shopify.com/blog/side-hustle) into a [reseller business](https://www.shopify.com/blog/reseller-business), creating your own website will give you more control over branding and the customer experience. Choose a selling app that lets you build a storefront to showcase [brand identity](https://www.shopify.com/blog/brand-identity) elements like your [brand colors](https://www.shopify.com/blog/choose-brand-colors). For example: - **Shop:** App directs customers to your ecommerce site, where they’ll see your brand identity on full display. - **eBay:** Lets you pay to add personalized elements to your storefront, like banner images. - **ThredUp:** Won’t allow buyers to see who they’re purchasing from. [Oakywood](https://oakywood.shop/en-uk?srsltid=AfmBOopegYtzZxmQ9K6QsW46cFIaqzSoFvbHAtMiYeUd2aWUpSl2flXZ) originally started selling its wooden furniture on Etsy but experienced the marketplace’s limitations when it grew. It faces increased competition for buyer attention. Also, potential customers who wanted to place a custom order had to complete a separate online form with no way to preview how the finished product would look. “I thought, ‘There needs to be a better way of doing this.’ So I looked and found Shopify,” says Oakywood’s founder Mateusz Haberny. “And the great thing about Shopify is that it was very easy to take a webshop to market in a matter of hours—not weeks.” Since migrating, [Oakywood recorded a 250% increase in sales](https://www.shopify.com/case-studies/oakywood) of key products. The brand recorded 200 reviews and an overall Trustpilot rating of 4.7 out of 5 stars in just a few months. If you run a Shopify store, you can use the [Marketplace Connect](https://apps.shopify.com/marketplace-connect) app to integrate your storefront with eBay, Walmart, Amazon, and Target. Marketplace Connect syncs inventory and pricing information and allows you to manage marketplace sales from your Shopify admin. 🥄 Success story: Old World Kitchen’s leap from Etsy to Shopify The Polder family started their handcrafted wooden spoon brand by selling door to door before launching on Etsy. Now, they sell both through the marketplace and a standalone ecommerce store. [Read the Polder family’s story](https://www.shopify.com/blog/211686281-moving-from-etsy-to-shopify) ## Tips for selling stuff online 1. [Use clear, detailed product images](#21) 2. [Write strong product descriptions](#22) 3. [Set appropriate prices](#23) 4. [Be safe](#24) Here are some tips for selling items on apps: ### Use clear, detailed product images High-quality [product photography](https://www.shopify.com/blog/12206313-the-ultimate-diy-guide-to-beautiful-product-photography) can affect click-through and purchase decisions. Some 61% of shoppers rely on product images when buying online, per [Salsify’s 2026 data](https://www.salsify.com/blog/how-consumer-buying-behavior-is-changing-in-2026). Although you can use your smartphone, consider investing in a higher-quality camera that gives you more control over depth of field and exposure. You can take professional photos with simple colored backdrops, or feature your products in a more natural setting. South Van Der Lee, who runs the Calgary-based company [GOGO Sweaters](https://gogosweaters.com/), features her products being worn outdoors. “It’s really important that we have photos—especially when you’re trying to sell online—that the shoppers can put themselves into,” South says in a [_Shopify Masters_](https://www.shopify.com/blog/gogo-sweaters-social-media-product-tips) interview. ### Write strong product descriptions [Product descriptions](https://www.shopify.com/blog/8211159-9-simple-ways-to-write-product-descriptions-that-sell) offer details about the item you’re selling. Salsify’s report found 51% of shoppers rely on this information when making a purchase decision. If you’re selling used items like furniture or secondhand clothing, give in-depth information about wear and tear. Transparency about the condition of your items can help prevent returns: [Shorr’s 2025 report](https://www.shorr.com/resources/blog/consumer-report-return-habits/) found 11% of all online-bought items are later returned because the product looked different in the flesh. [Sidekick](https://www.shopify.com/magic), the AI assistant baked into Shopify, can use AI to write product descriptions for you. ### Set appropriate prices Research similar products and evaluate how their asking price is justified. If you’re selling new items, [price your products](https://www.shopify.com/blog/how-to-price-your-product) in relation to variable costs like raw materials and production and fixed costs like overhead. Then add a markup to ensure a target [profit margin](https://www.shopify.com/blog/what-is-profit-margin). Use Shopify’s [profit margin calculator](https://www.shopify.com/tools/profit-margin-calculator) to find an appropriate price. If you’re selling secondhand products, setting a price isn’t as straightforward. Consider the initial selling price of your product, its condition, and its rarity. Check prices across platforms to see how similar products are valued. ### Be safe To stay safe when selling items online: - Never give buyers any personal information, and avoid inviting buyers into your home. - Choose a safe, visible meeting spot in a public place, like outside of a police station, if you’re selling locally. - Check out potential buyers’ profiles before meeting with them to see if they are who they claim to be. - Use secure payment methods like PayPal, Stripe, or [Shopify Payments](https://www.shopify.com/payments). 8,000 apps to help you sell Expand your store with apps.
