If your eCommerce sales efforts haven’t gone well before, or you just want some extra cash, you should consider doing business via an online marketplace. If you’ve never worked with a marketplace before though, you should acquaint yourself with what is marketplace, the different types of marketplaces, and what a marketplace business model is.

Once you have the basics down, read about marketplace selling and what buyers expect on these platforms. This will put you ahead of the competition early on, even if it's your first time using a selling app. Then, choose an online marketplace to sell on and start coaxing shoppers to check out your digital storefront. 

You can take the efficiency one step further and research the best marketplace apps, too. Sales apps are convenient because you don’t need to know how to build an eCommerce website. They also help you update product listings wherever you are and contact customers rapidly. 

Keep reading for our list of the 7 best marketplace apps and their core strengths.

Online Marketplace Apps

Perhaps you’re a business owner who’s always on the go. You may also be savvy and know that reaching mobile customers means using buying and selling apps. 

No matter what your reason is for growing the mobile side of your business, one thing is true: you should use the best tools available. Here are the top online marketplace apps that are crushing it. 


One of the most famous apps to sell stuff and eCommerce website examples is still one of the biggest. eBay is known for offering both direct to consumer and B2B business model sales opportunities. Users can post items for sale or list batch goods under an auction or fixed price and sell to anyone who’s interested. 

eBay launched their app in 2008, just one year after the iPhone was launched. The company has continually improved the app since then, making it easier to list products on the go. If you sell bulk lots or are looking for wholesale items to sell, eBay is great to consider. 


As one of the most successful and certainly the largest, Amazon remains a leading online marketplace app. Ever since the company has grown beyond selling books, they’ve sought to support sellers in many ways. 

Amazon is partly known for how many selling options they provide. The main types are third-party seller, Fulfilled by Amazon (FBA), Fulfilled by Merchant (FBM), first-party sales (sold by Amazon), and Amazon Vendor. Each selling channel offers specific advantages that suit different types of eCommerce businesses, like affiliate marketing vs. dropshipping

One of the biggest benefits of selling on Amazon is their built-in traffic, which amounts to billions of views each month. Adding Amazon to your list of profitable marketplace apps is often a wise decision. 


Etsy, originally known as an online hub for handmade items and lifestyle products, has grown into a booming online marketplace app. The DIY-driven platform lets users sell hundreds of high demand products to the nearly 400 million people who shop on the site monthly. 

Etsy’s seller user interface (UI) is straightforward and makes it simple to list a product in minutes. They do charge listing and transaction fees, but both are nominal. The primary demographic on Etsy is women ages 18-35, so if your business caters to this market, you’ll find a welcoming audience here.

Facebook Marketplace

Need a way to sell unwanted items to people you may already know? Facebook Marketplace, owned by the social network Facebook, is the ideal choice. Instead of creating a brand new website, Facebook did what they do best--launched a new feature for their built-in, massive audience. 

Though Facebook Marketplace’s monthly traffic is low compared to eCommerce giants like Walmart and Amazon, its ease-of-use makes it appealing for newcomers. People can sell personal items in a fashion similar to Craigslist, or they can use it as an eCommerce storefront similar to Etsy or eBay. Facebook Marketplace is useful if you’re just getting started and haven’t used an eCommerce website builder before. 


Though not always considered a marketplace, Craigslist is still one of the most popular ways to list various items for sale. Originally, Craig Newmark created his namesake site as a way to share event info with his Bay Area friends. It quickly grew into a popular classified ads site with over 350 million monthly visits and 40 employees. 

Craigslist is an informal marketplace, meaning anyone can sell just about anything. This can be useful if you’re selling a small amount of handmade goods, but becomes more difficult the more you want to sell. Add to this the fact that Craigslist requires manual refreshing of item listings, and the daily work can add up. 

Craigslist is a strong option for garage sales, moving sales, small-batch products, and local product exchanges. If you’re considering eCommerce business ideas that rely on scaling quickly, you may find more success on a different platform. 


OfferUp is a relative newcomer to the marketplace app scene but has become exponentially popular in recent years. They support direct selling between private consumers and focus on a mobile-first design. Many OfferUp users have praised the app for how effortless it is to list and sell an item.

There are several factors distinguishing OfferUp from competitors. One, users can create profiles and give other users ratings and reviews. This makes it easier to vet a seller and build trust before contacting them. 

Two, OfferUp combines many popular elements of both auction sites and fixed price sites. In other words, shoppers have the option of negotiating price without necessarily getting involved in traditional bids. These features make it simple for anyone to get started and build a low-cost audience. 

There’s An App For That

Researching ways to increase eCommerce sales online isn’t always the easiest. In addition to having an eCommerce business plan and eCommerce marketing strategy, you need people to be interested in your products. That’s why getting involved in a marketplace early is a great call. At first, growing your brand on a marketplace app may feel out of place. It may feel like the social media version of eCommerce, but in truth, this method has several upsides. 

Most eCommerce marketplace apps have millions of monthly visitors built into them, so getting your first few sales can be easier than doing it solo. As you build up an audience on an app, you can encourage your buyers to support you elsewhere. Keep selling great products at competitive prices and you can’t go wrong.
