1. Shop
The Shop app is an additional way to make money on Shopify for merchants with an online store. 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, 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—a rewards program that lets buyers earn virtual cash when they use the Shop app—and detailed shipment tracking.
Customers who buy on Shop have access to the built-in Shop Pay wallet, which can convert up to 50% higher than guest checkout. They can also use Shop Pay Installments, a buy now, pay later option that lets qualified customers make interest-free installments on larger purchases.
Using the Shop app also gives you access to Shop Campaigns, a pay-per-conversion program that lets you target new customers with exclusive offers.
As Andrius Baranauskas, director of product at Shopify, explains on an episode of Shopify Masters, “We have brands like Unilever brand Liquid I.V. that were using the product and they saw a 40% reduction in customer acquisition cost using Shop Campaigns.”

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.

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

This market is growing: The global secondhand apparel market is projected to reach $367 billion by 2029. 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.

Etsy offers a mobile app for customers shopping on their phones. It also has an ad platform that lets you buy advertisements both on and off Etsy to drive more traffic to your shop. It’s not useful for traditional dropshipping.
If you’re on Shopify, you can sync inventory and manage sales from your Shopify admin using the Marketplace Connect app.
Who it’s for
Crafters—though brands like Explorer Knits + Fibers migrate from Etsy toward Shopify when they grow.
“What went from an Etsy shop where I was selling 10 or 15 hats a month turned into me having a Shopify website and building my own brand,” says Explorer Knits founder Ali Osterholz in a Shopify Masters interview.

9. ThredUp
ThredUp is a consignment platform that helps you sell your used clothing. It lists 50,000 new products daily.

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). If you earn less than this amount when your clothing sells, you won’t be charged the difference.
ThredUp selling fees depend on the selling price of the item:
- $5 to $19.99: ThredUp takes 85% to 97% of the product price
- $20 to $49.99: ThredUp takes 70% to 85%

Alongside selling products via livestream, you can have a Whatnot shop to showcase items they have for sale. Similar to eBay, you can run an auction or use “buy it now” pricing.
Whatnot requires sellers to apply and be approved. It says most sellers get access straight away, but in some cases, you’ll need to submit extra information for Whatnot to review.

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.

How to choose the right selling app
Consider these factors when choosing an app for selling items online:
1. Consider your audience
Identify your product’s 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 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, 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 by cleaning out your closet or selling your old electronics, you might not care about building a brand. But if you’re considering turning a side hustle into a 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 elements like your 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 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 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 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.
Tips for selling stuff online
Here are some tips for selling items on apps:
Use clear, detailed product images
High-quality 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.
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, 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 interview.
Write strong product descriptions
Product descriptions 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 found 11% of all online-bought items are later returned because the product looked different in the flesh.
Sidekick, 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 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. Use Shopify’s 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.
