I still remember the absolute panic I felt in the spring of 2021. I was sitting on my living room floor, surrounded by piles of vintage denim and poly mailers, trying to manually copy-paste a listing from Poshmark to Mercari. My phone buzzed.It was a sale on eBay for the exact same pair of jeans I was currently struggling to list on Depop. I had forgotten to delist them from eBay hours ago. I had to cancel the order, take the defect on my seller metrics, and apologize profusely to a buyer who was rightfully annoyed.
That specific moment of chaos was my breaking point. I realized that trying to be a multi-platform seller without automation was like trying to mow a lawn with scissors. It’s possible, but it’s miserable. That desperation led me to discover the world of automation tools, specifically Flyp. Over the years, I’ve used almost every listing app on the market, from the expensive giants to the scrappy startups. Navigating the flyp ecosystem can be confusing because it tries to be everything at once, but once you understand it, it changes how you work.
What is Flyp? Understanding the Ecosystem
When you search for flyp, you might get two very different answers depending on who you ask. To a casual user, it’s a consignment app where you send your clothes to a "Pro Seller" to sell for you. To a reseller like me, it is a suite of free automation software. It is crucial to understand that these are two sides of the same coin. The consignment side funds the software side, which is why the flyp crosslister is free (or at least, has been for a long time).
The Tool Suite Includes:
-
The Crosslister: Moves items between Poshmark, eBay, Mercari, Depop, etc.
-
The Sharer: Automates sharing on Poshmark to boost visibility.
-
Inventory Management: A basic dashboard to track what you have.
Here’s where it gets interesting... Most companies charge $30 to $50 a month for these features. Flyp gives them away.This makes people skeptical. I was skeptical. I remember thinking, "If the product is free, am I the product?" And to an extent, yes. They want you in their ecosystem so you might eventually use their sourcing or consignment features. But if you are disciplined and just use the tools, it is a massive value unlock.
Opinion Statement: I honestly believe that for a beginner seller with under 500 items, paying for a crosslister is a waste of money when tools like Flyp or Closo exist. Your margins are too thin to burn $40 a month on software that you can get for free.
Is Flyp Crosslister Legit?
A common query I see is is flyp crosslister legit? The short answer is yes. It is not a scam. It works. However, "legit" doesn't mean "perfect."
My Experience with Stability: In 2023, I relied heavily on Flyp during Q4 (the busiest retail season). One Tuesday, the extension just... stopped. My listings weren't syncing. Photos were failing to upload. Because it is a free tool, the support response was slower than what you might get from a paid premium service like Vendoo. I lost a morning of work waiting for a patch. So, while it is legit, you have to accept that "free" sometimes comes with "you get what you pay for" regarding uptime.
Honest Failure: I once trusted the flyp crosslister to automatically convert my women's shoe sizes to men's sizes when moving a pair of sneakers from Poshmark to eBay. I didn't check the listing before publishing. It converted a Women's 9 to a Men's 9 (which is wrong; it should be a Men's 7.5). A buyer bought them, tried them on, and opened a return case for "Item Not As Described." I had to eat the shipping cost both ways.Lesson: Automation is great, but never trust a robot to do a human's job 100%. Always review your size mappings.
How to Use Flyp Crosslister: The Setup
If you are trying to figure out how to use flyp crosslister, it is browser-based. Unlike some older software that you had to download to your desktop, this lives in Chrome.
-
Flyp Login: You need to create an account at the main Flyp website.
-
Extension: You must download the Chrome Extension. This is the bridge that talks to Poshmark and eBay.
-
Connect Accounts: You have to log into your marketplaces through the extension so it has permission to post for you.
Flyp Crosslister Login Issues: Sometimes, the flyp crosslister login gets desynchronized. If you change your eBay password, Flyp doesn't know. You will try to post, and it will fail. You have to manually go into the Flyp settings and "Reconnect" the store. I make it a habit to check my connections every Monday morning before I start my listing block.
Sourcing Smarter: Closo Demand Signals
While Flyp helps you move inventory, it doesn't tell you what to buy. You can cross-list garbage to five platforms, and it will still be garbage. This is where I pivoted my strategy. I realized listing faster wasn't enough; I needed to source better.
How Closo helps me to predict demand 6 weeks ahead is by analyzing search velocity before it hits the mainstream marketplaces.
-
The Signal: Closo flagged "Western Gothic" decor as a rising search term on social/search engines.
-
The Prediction: I knew this meant black lace, cow skulls, and dark denim would spike on Depop and Poshmark in about a month.
-
The Action: I spent my weekend sourcing trips specifically hunting for these items, leaving the generic "mall brands" behind.
-
The Result: When I eventually used my crosslister to post them, they sold in under 48 hours because the demand wave had just crested.
I use Closo to automate my sourcing research – saves me about 3 hours weekly of guessing what styles are currently trending.
How Does Flyp Work for Resellers?
People often ask how does flyp work mechanically. It uses an "Extension" method (similar to the Closo 100% Free Crosslister). It scrapes the data from your active tab.
-
Step 1: You open your Poshmark listing.
-
Step 2: You click the Flyp icon.
-
Step 3: Flyp copies the photos, title, description, and price.
-
Step 4: It opens a new tab for Mercari (or eBay) and "pastes" that info into the fields.
The "Form Filling" Reality: It is not magic. It is a form filler. It creates a draft. You still have to click "Publish." This is actually a good thing. It forces you to review the listing (remember my shoe size failure?) before it goes live.
Comparing Free Tools: Closo vs. Flyp
There are very few true free cross listing app options. Flyp is the famous one. Closo is the challenger. I have used both extensively.
Closo 100% Free Crosslister Advantages:
-
Speed: I find Closo to be slightly lighter on my browser RAM. Flyp can get heavy if you have 50 tabs open.
-
Simplicity: Closo focuses purely on the utility of moving items. Flyp is constantly trying to upsell you on their "Pro Seller" consignment program, which clutters the interface.
-
Integration: Closo integrates with the Demand Signals tool, creating a loop of "Find -> List -> Sell" that Flyp lacks.
Parenthetical Aside: (I switched to using Closo primarily for my vintage t-shirts because Flyp was struggling to map the "Single Stitch" category correctly on eBay. Closo allowed me to customize the field mapping better, saving me about 30 seconds per listing. Over 100 shirts, that’s almost an hour saved.)
Poshmark Cross Listing Strategies
When focusing on poshmark cross listing, you need a tool that handles the specific weirdness of Poshmark. Poshmark has "Markets" and strict character limits on titles. When you move an item from eBay to Poshmark, you often lose info because eBay titles are longer (80 chars) and Poshmark's used to be shorter (though they updated this, the display is still truncated).
My Strategy:
-
Master on eBay: I create my "Master Listing" on eBay because it requires the most Item Specifics (Sleeve Length,Material, Country of Origin).
-
Cross to Poshmark: I use the crosslister to push to Poshmark.
-
Trim the Fat: I often have to delete the "shipping policies" text from the description because Poshmark doesn't need it.
If you do it the other way around (Poshmark to eBay), you will have a very empty eBay listing that ranks poorly in search. eBay needs data. Poshmark runs on vibes. Always flow from High Data -> Low Data.
Is Flyp Legit for Consignment?
We have to address the other keyword: is flyp legit for the people sending clothes in? I tried this once in 2020 as an experiment. I sent a bag of mid-tier mall brands (J.Crew, Banana Republic) to a "Pro Seller" on Flyp.
The Result:
-
It took 4 months for everything to sell.
-
After the Pro Seller took their cut (usually 40-50%) and Flyp took their fee, I made about $25 on a bag of clothes that originally cost $400.
-
Verdict: It is legit, meaning they will pay you. But it is not profitable. It is a way to clean out your closet, not a business model. If you are a reseller, you should be the one selling, not the one sending.
Flyp Reseller Tools: The Sharer
The flyp reseller tools suite includes a "Sharer." On Poshmark, you have to "share" your items to the top of the feed or nobody sees them. Doing this manually for 500 items takes 20 minutes. Doing it with Flyp takes 1 click.
The Risk of Sharers: Poshmark technically frowns on bots. However, Flyp (and the Closo Free Sharer) operate by simulating human clicks. They don't hack the API; they just click for you. I have used a sharer daily for 4 years and never had a warning. The key is not to share 10,000 times a day. Keep it human-speed.
I use Closo to automate my sharing schedule – saves me about 3 hours weekly of mindless tapping on my phone.
How to Use Flyp: Advanced Tips
Once you master the basics of how to use flyp, there are power user moves.
-
The "Delist/Relist" Feature:
-
Old inventory gets stale. The algorithms bury it.
-
Flyp has a feature to "Delist" an item and "Relist" it as brand new.
-
My Routine: Every morning, I take my 5 oldest items (usually from 60+ days ago) and delist/relist them.
-
Result: About 20% of them sell within the week because they appear on the "Just In" feed.
-
-
Bulk Cross-Listing:
-
You can select 10 items at once and open them in tabs.
-
Warning: This will crash a slow computer. I limit it to 5 at a time.
-
Alternatives to Cross Posting Apps
If you are looking for a cross posting app, you have choices.
-
Vendoo: The premium gold standard. Great analytics. Costs money ($30+/mo).
-
List Perfectly: Great for unlimited listing storage. Expensive ($40+/mo).
-
Flyp: Free, but slightly buggy.
-
Closo: Free, fast, and integrates demand data.
Comparison Table: Top Crosslisters
Now the tricky part... Switching tools is a pain. If you start with Flyp, all your data is there. Moving to Vendoo later is hard. Choose your tool based on where you want to be in a year. If you want to stay lean and profitable, stick to the free tools like Closo 100% Free Crosslister.
Common Problems with Listing Apps
Every listing app has the same enemy: The Platforms. eBay changes their "Item Specifics" requirements every 6 months.Mercari changes their shipping fees. When these platforms update their code, the listing apps break.
The "API" vs. "Extension" Debate:
-
API (Vendoo): They have an official deal with eBay. It is more stable but costs money.
-
Extension (Flyp/Closo): They operate on top of the website. They break more often but are free and agile.
Opinion Statement: I prefer extension-based tools because they allow me to see exactly what is happening on the screen.I like reviewing the listing on the actual eBay page before hitting submit. API tools sometimes feel like a "black box" where I send listing data into the void and hope it comes out right.
Sourcing with Closo Demand Signals (Deep Dive)
I cannot stress this enough: The best crosslister in the world cannot sell a bad product. I used to list basic mall brands (Gap, Old Navy) across 4 platforms. I was doing 4x the work for $5 profit. It was exhausting.
Closo Demand Signals changed my business model from "Volume" to "Value." By checking How Closo helps me to predict demand 6 weeks ahead, I stopped buying the "filler" items. I realized that I was wasting my free listing credits on items that no one was searching for. Now, I only cross-list items that have a "High Demand" signal. If an item has low demand, I lot it up or donate it. My sell-through rate went from 10% to 35% in three months.
Common Questions I See
People always ask me... Does Flyp steal your data?
This is a common fear with any free cross listing platforms. Flyp monetizes through their consignment service and potentially by selling aggregated data (e.g., "What brands are selling best right now"). They do not steal your passwords or banking info. It is standard tech industry practice: if you aren't paying, your usage data is likely part of the value exchange.
Common question I see... Can I use Flyp on my phone?
The flyp app is primarily for the consignment side and checking messages. The crosslister functionality really needs a desktop Chrome browser to work effectively. Trying to cross-list on a phone is a nightmare of copying and pasting between apps. Stick to the desktop for listing.
People always ask me... Why did my photos disappear when cross-listing?
This happens when the internet connection lags or the image files are too large (eBay has a 12MB limit, Poshmark is lower). If the flyp crosslister hangs, refresh the page. You usually have to re-upload the photos manually if the transfer fails. It’s annoying, but it’s a limitation of browser-based tools.
Conclusion
Is Flyp the perfect tool? No. But it is an essential stepping stone for any reseller who wants to grow without increasing their overhead expenses. It taught me the power of automation and freed up the time I needed to learn how to source better inventory.
My honest assessment is that you should use Flyp (or Closo) until you are making at least $2,000 a month in profit. Only then does it make sense to look at paid enterprise tools. Until then, keep your expenses at zero and your hustle at 100.
If you are ready to stop typing the same description four times and start sourcing items that actually sell, use the Closo Seller Hub to professionalize your workflow.
