19 Online Selling Apps for Every Type of Seller (2026)

Choosing the right online selling apps is the difference between a side hustle that drains your wallet and a business that generates consistent cash flow. Whether you want to clear out your closet or start building a global eCommerce brand, there's a specific platform engineered for your exact goal. But if you try to sell vintage streetwear on Amazon or generic electronics on Depop, you're going to fail.

I've seen too many entrepreneurs get stuck because they picked a platform based on hype rather than their business model. You need to align your choice with your budget, your tech skills, and your specific product.

To help you stop guessing, here are my top 19 apps to sell products online, categorized by how they help you make money.

How to Choose the Right Sales Channel for Your Goals

Don't download every app on this list just yet. You need to understand the trade-offs you're making. In my experience, the decision usually comes down to three factors: traffic, product fit, and verification.

First, I advise new sellers to choose between traffic and control. Marketplaces like Amazon or eBay bring you customers instantly, but they charge high transaction fees for that privilege. Storefronts like Shopify give you total control over your brand and profit margins, but you have to do the hard work of marketing to get people to your site.

Second, consider your product fit. If you sell bulky furniture, shipping costs will kill your margins on a global platform. You need a local app like OfferUp. If you sell trendy vintage clothes, they'll get lost on Amazon but will likely fly off the virtual shelf on Depop.

Finally, think about verification. Open classifieds are rife with scams. Using platforms that verify their users—or tools like SaleHoo that help you find reliable, vetted suppliers—drastically reduces the risk of fraud.

Now that you know what to look for, here's a quick overview before we dive into each platform:

Online Selling Apps by Category

Product Sourcing

1. SaleHoo (Dropship & Directory)

I put SaleHoo first because it bridges the gap between starting small and scaling up. Most sellers feel forced to choose between dropshipping apps or holding inventory, but I've found the smartest entrepreneurs in 2026 are using a hybrid model. SaleHoo supports both.

If you want to test products without risk, SaleHoo's dropship tool allows you to import trending items directly to your store. You don't buy stock until you make a sale. Once you find a winning product, you can use SaleHoo's supplier directory to find a wholesale supplier. This lets you buy in bulk to improve your margins.

What makes this platform unique is the safety factor. Every supplier in the directory is pre-vetted by the SaleHoo team. You aren't gambling on a random factory that might ghost you. Plus, SaleHoo's Market Insights give you real sell-through data so you can validate a product before you spend a dime on ads.

Best for: Entrepreneurs who want a safe, data-backed way to source products and scale a store.

Build Your Own Store

2. Shopify

Shopify is the ecosystem leader for a reason. It powers everything from small startups to massive celebrity brands. The real power lies in "Unified Commerce." I love how it syncs your online store with physical point of sale (POS) systems and social selling channels seamlessly.

Shopify offers flexible pricing to match your needs. The $5/month Starter plan is perfect for social selling without a full storefront, ideal if you're just selling through links on Instagram or TikTok. For a complete eCommerce store with all the features, the Basic plan starts at $39/month. For dropshippers ready to start selling on Shopify, the integration is seamless. You can connect the SaleHoo Dropship app to your Shopify store to import products with one click. It handles the inventory syncing automatically, so you never sell an item that's out of stock.

Best for: Building a professional, scalable brand with automation.

3. BigCommerce

BigCommerce is the scalable asset for growing brands. Unlike some platforms that charge you for every little plugin, BigCommerce comes with robust SEO and multi-channel features out of the box.

It's particularly strong for B2B sellers or stores with massive catalogs. If you have thousands of SKUs, this platform handles the data better than most. It's designed for brands that are ready to move beyond the "side hustle" phase.

Best for: High-volume brands needing advanced SEO and catalog tools.

4. Square Online

If you already have a physical shop or sell at local markets, Square Online is your easiest path to the web. It syncs perfectly with the Square card reader you likely already use.

This means your inventory is updated in real-time whether you sell a candle in person or online. It offers a free starter plan that's very robust, making it a low-risk option for local retailers who want to start offering "buy online, pick up in store."

Note on pricing: Square Online's free plan charges 3.3% + $0.30 per online transaction. Upgrading to their Plus tier ($49/month) reduces this to 2.9% + $0.30, which may be worthwhile for those processing higher volumes.

Best for: Brick-and-mortar retailers going digital.

5. WooCommerce

WooCommerce is for the control freaks. It's a plugin that runs on WordPress, meaning you own the data and the platform completely. You aren't renting your store from a company that can hike fees next month.

However, you're responsible for hosting, security, and maintenance. It's not a "set and forget" solution. But if you want to avoid platform lock-in and have the technical skills to manage a site, I believe it's the most cost-effective long-term option. SaleHoo's directory works with any platform, including WooCommerce, so you can still use it for sourcing products efficiently.

Best for: Tech-savvy sellers who want total ownership.

Major Marketplaces

6. Amazon Seller Central

Amazon is the volume play among online selling apps. You accept lower margins and strict rules in exchange for access to billions of monthly visitors. It's a "pay-to-play" environment now, meaning you'll likely need to spend money on Amazon ads to get your first sales.

The biggest advantage here is Fulfillment by Amazon (FBA). You ship your inventory management burden to their warehouses, and they handle packing, shipping, and returns. I consider this crucial because Prime members expect two-day shipping. If you have a private label brand and want to move massive volume, check the current Amazon pricing to see if your margins can support the fees. Most categories fall between 8-15% referral fees, but be aware that some categories run higher: clothing over $20 incurs 17%, jewelry commands 20% up to $250, and watches face 16% fees, plus FBA costs on top.

Best for: Sellers with their own brand who want to scale volume quickly.

7. eBay

eBay has evolved from an auction site into a global collector's hub. While the auction format is less relevant today, the "Buy It Now" feature dominates sales. The platform has introduced an International Shipping Program that handles customs and logistics for you. You just ship the item to a domestic hub, and eBay handles the rest.

This makes it incredibly easy to sell to buyers in Europe or Asia without the headache of international postage. I still think it's the best place for used electronics, auto parts, and collectibles.

Best for: Selling collectibles and used goods to a global audience.

8. Etsy

Etsy is still the king of handmade goods, but the landscape has shifted toward Print-on-Demand (POD). Many sellers now design graphics and use POD partners to print them on mugs or shirts, which Etsy allows as long as you disclose the production partner.

Be careful with their strict "handmade" definitions. You can't resell generic mass-produced goods here. Also, I warn all my students: be aware that fees can stack up between listing fees ($0.20), transaction fees (6.5%), and offsite ads. You need to price your products high enough to absorb these costs.

Best for: Unique, custom, or vintage items.

Local Selling

9. Facebook Marketplace

Facebook Marketplace has become the default "yard sale" of the internet. Unlike Craigslist, Facebook Marketplace uses an algorithm to show your items to locals who actually buy similar things. It's much faster for moving general household goods.

While they offer shipping options, be aware that the selling fee for shipped items increased to 10% in April 2024. Because of this, the local pickup feature is the killer application here. It remains free. It builds trust because buyers can see your profile. It's high velocity, low friction, and perfect for clearing out clutter this weekend.

Best for: Fast, local sales of household items (Local Pickup).

10. OfferUp

OfferUp merged with Letgo to become the largest mobile marketplace for local buyers. Its standout feature is "TruYou" verification, which requires users to scan their ID. This builds a layer of trust that Craigslist lacks.

As of September 2025, OfferUp has discontinued its nationwide shipping feature to focus entirely on local transactions. This means no more shipping fees or complex logistics. Just pure, local buying and selling. It's fantastic for selling your car, sofa, or old tools. The app is chat-heavy, so be prepared to negotiate with buyers in real-time.

Best for: Verified local transactions for cars and furniture.

11. Craigslist

Craigslist is ugly, outdated, and incredibly effective. It remains the "Cash King" for high-margin local sales because it charges zero listing fees for most categories. You keep 100% of the profit.

I recommend Craigslist specifically for items that are expensive to ship. If you're flipping furniture, gym equipment, or large appliances, this is your best bet among local places to sell online. The "cash and carry" model means you get paid instantly without waiting for bank transfers. Just be vigilant about safety and meet in public places.

Best for: Selling bulky items locally without paying platform fees.

Fashion & Resale

12. Poshmark

Poshmark has transformed into a social shopping engine. The biggest trend right now is "Posh Shows," which are live video selling events. It's like QVC for your closet. You can move inventory incredibly fast by going live and interacting with buyers.

The fee structure is simple: they take a flat 20% commission on sales over $15 (or $2.95 for sales under $15). This sounds high, but it covers credit card processing and, most importantly, provides a pre-paid shipping label. You don't have to weigh packages or calculate zones. Just stick the label on a Priority Mail box and drop it off.

Best for: Selling fashion via live video and community sharing.

13. Depop

If you're targeting Gen Z, you need to be on Depop. The interface looks more like Instagram than a store, and aesthetics matter here more than anywhere else. Your photos need to be styled and moody.

And here's the best part for US sellers: Depop removed its selling fees in 2024. While buyers now pay a small marketplace fee, as a seller, you keep more of your earnings. Note that you'll still pay a payment processing fee of 3.3% + $0.45 per transaction, which is standard across platforms. This app dominates the Y2K and vintage streetwear niche. If you're under 30 or selling online to that demographic, this is your engine.

Best for: Vintage fashion and streetwear for younger buyers.

14. Mercari

Mercari is designed to be the easiest app to use among the many apps to sell used goods. It's perfect for people who find eBay too complicated. Their "Mercari Local" integration allows Uber drivers to pick up items from your house and deliver them to local buyers, which removes the hassle of meeting strangers.

After briefly experimenting with a zero-fee model for sellers, Mercari reintroduced a 10% seller fee in January 2025, alongside a buyer service fee. Despite the fees, it remains excellent for general clutter that isn't trendy enough for Depop or high-value enough for eBay.

Best for: Casual sellers cleaning out their closets.

15. Vinted

I've watched Vinted grow massive in Europe, and it's quickly gaining ground in the US thanks to its unique business model: the buyer pays the fees. As a seller, you keep 100% of the sale price.

This makes it ideal for low-cost "fast fashion" resale where margins are usually too tight to support a 20% commission. If you have a lot of Zara or H&M clothes to sell, Vinted allows you to actually make a profit on a $10 item.

Best for: Selling low-cost clothing with zero seller fees.

16. Whatnot

Whatnot is the largest live selling app in the world, and it's changed how resellers move inventory. Think QVC meets TikTok. You host live video auctions where buyers bid in real time, creating an energy that traditional listings can't match.

Founded in 2019, Whatnot started as a collectibles marketplace focused on sneakers and Funko Pops, then quickly expanded to include trading cards, comics, and fashion. Now it covers 250+ categories including vintage clothing, sneakers, and electronics. Women's fashion alone averages 13,000 live streams at any given moment.

The fee structure is straightforward: Whatnot takes an 8% commission plus a 2.9% + $0.30 payment processing fee, totaling about 11%. That's significantly cheaper than Poshmark's 20%. And if you're not comfortable on camera, Whatnot Marketplace lets you create traditional "buy it now" listings without going live.

The catch? You must apply and get approved before you can sell. They vet sellers for quality control. But once you're in, the engagement is unmatched. Over 175,000 hours of livestreams are hosted each week, which is 800x more than QVC's weekly broadcast hours.

Best for: Sellers who thrive on live interaction and want to move collectibles, vintage, or fashion inventory fast.

Social Commerce

17. Facebook Shops

Don't confuse this with Marketplace. Facebook Shops allow you to create a customizable, mobile-first storefront that lives on your business page. It's less about clearing out your garage and more about creating a curated shopping experience for your followers.

While Meta has made changes to their checkout integration, this tool works best as a discovery catalog. You connect it to your main eCommerce site so users on Instagram and Facebook can browse your products seamlessly. It's essential if you plan to run ads on Meta platforms.

Best for: Brands that want to turn social engagement into sales.

18. TikTok Shop

TikTok Shop has replaced older apps like 5Miles as the dominant force in mobile commerce. It's a video-native selling platform where products are tagged directly in videos. This taps into impulse buying like nothing else.

You don't necessarily need a massive ad budget here. If you create entertaining content that goes viral, you can generate thousands of sales overnight. The standard referral fee is 6% per order, which is competitive compared to Amazon. With social commerce now accounting for about 19% of global eCommerce sales, ignoring TikTok is leaving money on the table. If you're exploring TikTok dropshipping, this is the platform to master.

Best for: Viral products and impulse buys.

Promotions & Deals

19. Groupon Merchant

Don't think of Groupon as a primary store. It's a customer acquisition tool. You'll likely break even or lose money on the initial sale because of the deep discounts required.

However, if you sell services (like spa treatments) or need to liquidate distressed inventory fast, it's powerful. You're paying for the lead, not the profit on the first transaction. Use it strategically to get people in the door, then upsell them later.

Best for: Liquidation and service-based customer acquisition.

Why You Need a Dedicated Selling App

You might be thinking, "Can't I just post on Instagram and ask people to Venmo me?" You can, but I guarantee you won't build a business that way. Today, mobile devices account for the majority of eCommerce visits. Buyers expect a frictionless mobile experience.

Dedicated apps provide trust. Strangers are hesitant to send cash to a random person, but they trust an app that holds funds in escrow. Furthermore, using the right software automates the tedious parts of selling online, like calculating sales tax and generating shipping labels. I've found this automation is the only way you can scale beyond a few sales a week without burning out.
