How to crosslist from Poshmark to Mercari | 2025

I’ve crosslisted hundreds of items like clothing and handbags from Poshmark to Mercari, using both manual methods and automated tools. Why did I crosslist? To increase my buyer pool and revenues. 

This guide will show how to crosslist from Poshmark to Mercari, highlight the differences between using manual methods and automated tools like Nifty, and discuss the common crossposting challenges. 

Why should I crosslist between Poshmark and Mercari? 

You should crosslist between Poshmark and Mercari because you’ll put your inventory in front of millions of additional shoppers. Poshmark has over 130 million users in the U.S. and Canada, while Mercari has around 23 million worldwide. Reaching nearly 150 million shoppers improves your chances of making sales. 

Both platforms attract different buyer types. Poshmark buyers shop for clothing and fashion accessories. They enjoy social features, like sharing, liking, and attending Posh Live Shows. 

Mercari shoppers want quick, convenient purchases across many categories. They look for deals and usually buy when a product fits their budget. By crosslisting from Poshmark to Mercari, you increase visibility and cut the time items sit unsold.

What you’ll need before you start

Before you start crosslisting from Poshmark to Mercari, you’ll need to set up the following:

• Active listings on Poshmark: When crossposting from Poshmark to Mercari, review your listings and remove any outdated or sold items. Make sure they’re accurately described and well photographed. Make sure you're only moving current inventory to Mercari.
• A Mercari account: Sign up for Mercari, complete your seller profile, and verify your account. Once you’ve jumped through these hoops, you can start listing. 
• Cloud storage for your account: Cloud storage through Dropbox or Google Drive keeps your files secure, backed up, and accessible anywhere, unlike storing them only on your computer. If your computer crashes or is stolen, your files stay safe in the cloud. Cloud storage lets you share and update files across devices.
• Inventory tracking spreadsheet or system: You’ll need a tool to transfer items between platforms and a system to track your listings. A simple spreadsheet with columns for item name, description, photos, links, and status keeps everything organized. 

How to crosslist from Poshmark to Mercari

You’ll need to keep your listing information accurate because mistakes can cause duplicate posts, pricing errors, or sold-out items to stay active. Follow these steps to crosslist from Poshmark to Mercari:

Step 1: Prepare your listings

Start by checking your Poshmark listings’ categories, descriptions, and photos fit Mercari’s format. Mercari uses different categories. For example, a “blazer” under “Jackets & Coats” on Poshmark might appear under “Tops” on Mercari.

Don’t forget to account for the different fee structures. Mercari charges a 10% selling fee, compared to Poshmark's 20%. Factor in shipping if you’re including it. Verify that the condition details match what buyers will receive to keep your ratings strong across both platforms.

Step 2: Option 1 – Manually copy listings to Mercari 

Open your Poshmark listing, save your photos to your cloud account, then upload them to Mercari in the same order to maintain a consistent look. Copy your title, description, and measurements to the Poshmark part of your spreadsheet to keep a record. 

Then, paste the listings into Mercari and manually edit the text to fit the platform’s format. Double-check each listing’s text for errors, duplicates, and missing data. 

Copy these finalized listings to the Mercari side of your spreadsheet and publish them on Mercari. 

Step 3: Option 2 – Use a crosslisting tool and skip manual steps

Manual crosslisting from Poshmark to Mercari takes longer (especially if you have many items), opens the door to errors, and feels flat-out clunky. But, I’ve come bearing good news: You can use a crosslisting tool and cut this lengthy manual process.

Here are a few crosslisting tools to consider:

Nifty’s AI removes manual data entry by converting your Poshmark listing details to match Mercari’s requirements, saving valuable time. 

Complete these tasks to crosslist items from Poshmark to Mercari using Nifty:

Task 1: Create a Nifty account. Then, connect your Poshmark and Mercari accounts to Nifty. 

Task 2: Click the “Resync” button at the upper-right-hand corner of your Inventory Manager to import your Poshmark listings into Nifty. Once complete, your Poshmark items will appear in your Inventory Manager. To crosslist them to Mercari, you'll need to select each item and click the “+ List on Mercari” button.

Task 3: Double-check your Inventory Manager to make sure all your selected listings are on Mercari. If not, click the “+ List on Mercari” button to update the listing. Don’t want to feature the listing on Mercari? Click the arrow above the listing’s picture, and select “Delist listing.”

Task 4: Click each item in the Mercari column. Although Nifty’s AI automatically adapts information like category, size, and other specifics to match Mercari's format, you should still double-check it and make necessary edits for Mercari’s audience. 

Task 5: Scroll down to the bottom of each listing, then click “List on Mercari” at the bottom right of that listing’s page. Your items are now also live on Mercari. 

Step 4: Track inventory across platforms

When an item sells on one platform, remove it from the other right away and record profit and inventory time on your spreadsheet. If you don’t remove it promptly, you might sell it twice and damage your professional reputation.

Overall, manual tracking means checking both platforms daily and removing listings yourself. This process may work if you have under 20 items, but once you start scaling, it becomes very tedious. 

For larger closets, tools like Nifty manage inventory, auto-delist sold items, and simplify pricing updates through one central interface. These crosslisting tools prevent overselling and let you manage hundreds of listings without constant manual work.

Common challenges resellers face while crosslisting

Crosslisting comes with challenges that can result in costly mistakes. Here are a few challenges you need to be aware of when crosslisting:

Challenge #1: Duplicate listings 

Selling the same item on both Poshmark and Mercari simultaneously risks two buyers purchasing it at the same time, forcing you to cancel an order and take a rating hit. 

Manual delisting requires constant monitoring across platforms, and forgetting to remove a sold item can damage your reputation with both buyers and the platform. However, you can mitigate this risk by using Nifty, which automatically delists sold items from all platforms after they sell. 

Challenge #2: Inconsistent item categories

Poshmark and Mercari organize products differently, so a “bodysuit” under “Tops” on Poshmark might fit under “Intimates & Sleepwear” on Mercari, depending on style. Placing items in the wrong category hides your listings from relevant searches, reducing visibility and costing sales.

Overcome this challenge by using a tool like Nifty that automatically pre-fills your Mercari information with translated details from your existing Poshmark listing. Nifty’s AI adjusts details such as category, size, and other specifics to match Mercari’s format. 

However, you’ll still need to review each field and make changes to be consistent with your brand. 

Challenge #3: Pricing discrepancies between platforms

Mercari charges a 10% seller fee, while Poshmark takes 20%. These discrepancies mean that identical prices yield different profits across platforms. 

Before publishing listings to both platforms, calculate the listing prices to reflect the fee differences. In many cases, an item’s Mercari price differs from its Poshmark price. 

Challenge #4: Tracking inventory

For sellers with fewer than 20 items, tracking inventory and profits in spreadsheets can work. But manual tracking systems are difficult to maintain accurately when you’re crosslisting over 20 items across Poshmark and Mercari. 

The more items you’re trying to track manually, the more hours you’ll spend (and errors you’ll make) updating cells, tracking listings, and updating prices instead of sourcing new inventory or getting to know buyers. 

Sellers with inventories of all sizes can save time with Nifty. The Analytics Suite provides insights into several metrics. Nifty tracks each sold item and gives you an overall view of your performance on both Mercari and Poshmark by tracking sales counts, average sales price, and profit change over time. 

Nifty also tracks expenses (including mileage for sourcing trips) and inventory costs, letting you record each method for either Accrual Accounting or Cash Accounting. These accounting features simplify year-end tax reporting.
