Top Platforms to Sell Stuff Online in 2025

No two marketplaces are the same — each comes with its own distinct features. To help you decide which ones can work for you, here are the overviews of some of the fastest-selling platforms. 

 

Facebook Marketplace

With an estimated 1 billion monthly active users, Facebook Marketplace is a great place for both local and online sales. Its easy listing process and wide range of selling categories make it attractive for beginner and experienced sellers alike. 

Unlike other platforms, Facebook is a social media site, so you can leverage the social element to maximize your sales. Sharing your listings with friends and posting to your local Buy & Sell groups will help you move your inventory faster. If you research similar listings and set competitive prices, you’ll have even higher chances of making quick and profitable sales. 

eBay

eBay is the second-largest e-commerce website in the US. It has 133 million active buyers worldwide and over 2 billion active listings

Best for electronics, collectibles, and apparel, eBay offers regular fixed-price listings and auction-style sales for even quicker turnarounds. It may require a learning curve, but its reselling features and tools are some of the best, compared to other platforms. 

👀Did you know that eBay also has powerful product research tools? You can use eBay to check sold listings, see average sold prices, and access other valuable metrics to boost your sales. 

If you take the time to understand eBay’s fee structure and price strategically to cover the fees and shipping costs, you’ll set yourself up for growth. 

Poshmark

If you’ve been wondering where to sell fashion stuff online fast, Poshmark is your answer. Similarly to Facebook, it combines the features of an e-commerce platform and social media where sharing and engagement help generate traffic and sales. 

Most popular for fashion, accessories, and home goods, Poshmark boasts a user base of 130 million people. Most resellers love it for the dedicated community of fashionistas and ease of use, admitting that high fees are worth it. 

To succeed on Poshmark, you need to stay active and engage with your buyers, sharing listings in your feed and constantly refreshing them. Offering bundles, free shipping, and discounts is also a great way to flip things for profit fast.

Etsy

Etsy is a perfect platform to connect crafty buyers and small artisan shops. If you’re looking to sell handmade items, vintage and custom clothes, craft supplies, or digital products, Etsy is the place to go. 

Setting up an Etsy shop is not free and takes time and effort. But what you get in return is a niche market for your goods and a more branded shopping experience for your potential buyers, which helps build trust and loyalty. 

💡Pro Tip: Experienced Etsy sellers highlight the importance of optimizing listing descriptions and titles, adding relevant attributes, and properly tagging items to boost exposure.

Bonanza

Bonanza is a smaller marketplace with over 40,000 sellers and 22 million products. While it doesn’t have the high traffic of larger platforms, its low fees and easy integration with Etsy, eBay, and Amazon can make it a worthy addition to your sales strategy. 

After setting up a Bonanza booth, you also get an opportunity to build your own standalone website and customize it to better fit your brand. You can choose from multiple unique themes, banner options, layout designs, and custom domains to have better control of your branding. 

Ruby Lane

Ruby Lane is a specialized marketplace dedicated to antiques, vintage items, art, and collectibles. With such a narrow focus, it ensures your listings reach a highly targeted audience of vintage enthusiasts, which is ideal if you’re selling high-value, one-of-a-kind items. 

Creating a shop on Ruby Lane is free, but there’s a service fee that applies to each sale and a monthly maintenance fee that can be waived if you list consistently. One thing that sets this platform apart is the knowledge base with tips and resources for sellers. They even used to publish a magazine featuring design trends and tips. 

Decluttr

Decluttr allows you to sell your old CDs & DVDs, books, and electronics like phones and tablets to make quick cash or simply declutter. 

Unlike traditional marketplaces, with Decluttr, you don’t have to wait for the buyer to find your item and order it — you just scan the item’s barcode and receive an instant offer from the platform. After that, you choose whether you’d like to get paid via PayPal, direct deposit, or check, and then ship the item for free. This literally is the fastest way to sell. 

Mercari

Another fast-selling platform, Mercari currently has over 23 million monthly active users. The app comes with a user-friendly interface for both buyers and sellers, which easily explains its popularity. There’s hardly anything you can’t sell on Mercari, with the most popular categories including apparel, home decor, toys, cosmetics, and electronics. 

Mercari charges moderate fees and offers some nice marketing tools and automation features to help sellers save time and effort. Staying active and regularly relisting your items is key on this platform. With Vendoo, you’ll be able to manage your inventory and automate your reselling processes on Mercari even more efficiently.

To make the most of Whatnot, pro sellers recommend setting a streaming schedule, making your shows interesting for your target audience, and collaborating with other shops to bring your viewers the best value. But don’t worry if livestream sales are not your thing — Whatnot also works as a traditional marketplace, allowing you to create regular listings and benefit from reaching a global audience.

Shopify (Own Store)

If you’re ready to take full control of your brand and scale your reselling business, you may want to consider creating your own store on Shopify. Unlike traditional marketplaces, having a Shopify store will allow you to build a unique brand identity and set your own rules. 

Success on Shopify depends on driving traffic to your store, so using SEO, running targeted marketing campaigns, and promoting on social media are key. Plus, with integrations like Vendoo, you can crosslist your products and conveniently manage all your inventory in one place.

 

Specialized Platforms (Grailed, Vestiaire Collective)

If you’re selling niche products like high-end streetwear, designer fashion, or luxury accessories, specialized platforms like Grailed and Vestiaire Collective are your best bet. These marketplaces have a dedicated customer base, meaning your listings will reach the shoppers who are specifically looking for authenticated, premium items. 

Both platforms have authentication processes and great buyer and seller protection policies in place, which makes selling high-value items faster and easier. To maximize your success, make sure to use high-quality photos and carefully follow the guidelines when creating your listings. 

 

How to Maximize Sales Speed on Online Selling Sites

To boost your sales and move inventory faster, it’s important to focus on strategies that help you stand out and connect with buyers more effectively. 

 

Optimize Listings

Optimizing your listings helps them appear in front of your potential buyers more often. Start with keywords and tags in your item descriptions because they help marketplaces identify and categorize your item accurately. Make sure your listings contain all the relevant details. Using high-quality photos is also crucial to attract your buyer’s attention. 

 

Price Competitively

To achieve a steady sales flow, you should set prices that are competitive enough to attract buyers but high enough to make a profit. Research your current competition across different marketplaces and take into account sold listings to come up with the right price for each item. 

 

Refresh Listings Regularly

Delisting and relisting can help you expose your inventory to more prospective buyers. While doing this manually may sound like a lot of work, Vendoo’s bulk delist & relist tool allows you to perform this in just a few clicks. 

 

Engage with Buyers

Creating a connection with your buyers is key to building a loyal customer base and making consistent sales. Respond to inquiries quickly and professionally, be polite, and make offers to entice buyers to complete their purchase. Ensuring the customer experience is seamless is also how you earn positive feedback. 

 

Leverage Social Media and Marketing Campaigns

Social media is a powerful tool for expanding your reach and driving traffic to your listings. Share your items on platforms like Instagram, Facebook, and TikTok to attract attention. Use relevant hashtags and engage with potential buyers by responding to comments and messages. You can also run targeted ads to increase visibility. 

 

Why Crosslisting Is Essential for Fast Sales

Crosslisting is a game-changer when it comes to speeding up your sales process. By crossposting your listings on multiple platforms, you get more people to see your products and, consequently, higher chances of making a sale faster.

 

The Benefits of Crosslisting

As you know, each marketplace caters to different demographics and interests. The more platforms you list on, the greater your chances of selling quickly, as each site has its own customer base. Also, it’s a good idea to diversify your sales channels so you don’t rely on a single platform and avoid the Kidizen scenario, where the platform announced its sudden closure back in October 2024, leaving many sellers stranded. 

 

How Vendoo Simplifies Crosslisting

Vendoo was created to make a seller’s life easier by automating the process of posting listings across different selling sites. Instead of manually entering the same details over and over, you can quickly publish your items on over 10 platforms. Refreshing your listings is also easy with Vendoo’s bulk delist & relist feature.  

Additionally, Vendoo allows sellers to manage their inventory from a single user-friendly dashboard. Features like listing templates make it even easier to create professional listings, while auto delisting prevents double selling by automatically deleting listings once they’ve been sold.

This level of automation not only speeds up your workflow but also helps run your business more efficiently.
