Selling on Mercari vs Poshmark vs eBay — 90-Day Test

1. Setting Up: Which Platform Gets You Started Fastest?

When you're starting out, the setup process can make or break your experience. Mercari takes the lead here, with a super simple sign-up process that took me less than 5 minutes. Poshmark was a close second, but it required a bit more effort to set up my profile and upload my first listing. eBay, on the other hand, felt like a chore. I had to verify my account, link my bank, and navigate a somewhat dated interface, which took about 20 minutes.

In terms of listing items, Mercari and Poshmark both make it easy with app-based photo uploads and straightforward forms. eBay's listing process is more detailed, which can be a pro if you're selling high-value items but feels overwhelming for casual sellers. For example, I listed a pair of sneakers on all three platforms: it took 3 minutes on Mercari, 5 minutes on Poshmark, and nearly 10 minutes on eBay. If you're in a hurry, Mercari is your best bet.

Key Stats:

• Mercari: 5 minutes to sign up and list your first item.
• eBay: 20 minutes to set up and list your first item.

2. Fees: How Much Do You Actually Keep?

Fees are a big deal when you're selling online. Mercari charges a flat 10% selling fee, plus a 2.9% + $0.50 payment processing fee. Poshmark, on the other hand, takes a hefty 20% cut for items over $15 (it's a flat $2.95 for items under $15). eBay's fees are more complicated, with a 12.9% fee for most categories, plus an additional $0.30 per order.

For example, I sold a $50 jacket on each platform. On Mercari, I kept $42.55 after fees. On Poshmark, I pocketed $40. On eBay, I ended up with $43.25. While Mercari and eBay were close, Poshmark's higher fees made a noticeable dent. If you're selling lower-priced items, the $2.95 flat fee on Poshmark can be a win, but for higher-ticket items, it stings.

Key Stats:

• Mercari fees: 12.9% total (10% + 2.9% + $0.50).
• Poshmark fees: 20% for items over $15.

3. Sales Speed: Which Platform Moves Inventory Fastest?

Speed matters when you're trying to flip items quickly. Over the 90 days, I sold 15 items on Mercari, 12 on Poshmark, and 20 on eBay. eBay was the clear winner in terms of volume, but it came with a caveat: I had to price my items lower to stay competitive. For example, I sold a pair of Nike sneakers for $40 on eBay, while the same pair went for $50 on Mercari (though it took two weeks longer to sell).

Poshmark was the slowest, but its social features like sharing and following other users can help boost visibility. I noticed that items with trendy brand names like Lululemon or Free People sold faster on Poshmark than generic brands. Mercari struck a nice balance between speed and price, especially for mid-range items like electronics or home goods.

Key Stats:

• Items sold in 90 days: eBay (20), Mercari (15), Poshmark (12).
• Nike sneakers: $40 on eBay (3 days), $50 on Mercari (2 weeks).

4. Shipping: Costs and Convenience

Shipping can make or break your profits, and each platform handles it differently. Mercari offers prepaid labels with rates starting at $3.99 for small items, which is super convenient. Poshmark has a flat $7.67 shipping fee for buyers, and sellers get a prepaid label for up to 5 lbs. eBay is the most flexible, letting you choose your own shipping method, but that also means more work.

I shipped a 2-pound package on all three platforms. On Mercari, the prepaid label cost $7.99. On Poshmark, the buyer paid $7.67, and I used the free label. On eBay, I chose USPS Priority Mail and paid $9.25 out of pocket, but I could've charged the buyer instead. If you value convenience, Mercari and Poshmark win. If you want control, go with eBay.

Key Stats:

• Mercari prepaid label (2 lbs): $7.99.
• eBay USPS Priority Mail (2 lbs): $9.25.

5. Audience: Who Shops Where?

Understanding your audience is key to making sales. Mercari attracts bargain hunters and casual shoppers, making it great for mid-range items like $20 to $50 gadgets or clothing. Poshmark is all about fashion, especially trendy or high-end brands. eBay has the widest audience, from collectors to deal-seekers, which makes it ideal for a broader range of products.

For instance, I listed a vintage Coach bag on all three platforms. It sold on Poshmark for $75 within a week, while it sat unsold on Mercari and eBay for over a month. On the flip side, a used iPhone sold on eBay for $300 in just two days, while it took over two weeks to sell on Mercari and never sold on Poshmark. Knowing your audience can save you a lot of time and effort.

Key Stats:

• Vintage Coach bag: $75 on Poshmark (1 week).
• Used iPhone: $300 on eBay (2 days).

6. User Experience: Which Platform is Easiest to Use?

When it comes to user experience, I found Mercari to be the most intuitive. Its clean design and simple navigation make it easy for beginners. Poshmark's app is visually appealing but requires more effort to engage with the community by sharing and following. eBay, while powerful, feels outdated and has a steeper learning curve.

For example, I had to spend about 10 minutes sharing my Poshmark listings daily to keep them visible, which was a bit of a hassle. On Mercari and eBay, I could list an item and forget about it until it sold. If you're short on time, Mercari is the easiest to manage, but if you're willing to put in the effort, Poshmark's social features can pay off.

Key Stats:

• Time spent sharing on Poshmark: ~10 minutes/day.
• Mercari listing time: ~3 minutes/item.

7. Overall Profit: Who Wins the 90-Day Test?

At the end of 90 days, I tallied up my profits. On Mercari, I made $650 from 15 sales, averaging $43.33 per item. Poshmark brought in $480 from 12 sales, averaging $40 per item. eBay topped the list with $860 from 20 sales, averaging $43 per item. However, when I factored in time spent, Mercari felt like the best balance of ease and profitability.

If you're selling niche or high-value items, eBay is the way to go. Poshmark is perfect for trendy clothing and accessories, but the higher fees can eat into your profits. Mercari is the middle ground, offering a good mix of ease, speed, and profit. Ultimately, the best platform depends on what you're selling and how much time you're willing to invest.

Key Stats:

• Total profit: eBay ($860), Mercari ($650), Poshmark ($480).
• Average profit per item: Mercari ($43.33), eBay ($43), Poshmark ($40).
