Crossposted: How I Doubled My Weekly Sales Without Listing Twice

Introduction: The Day I Realized One Platform Wasn’t Enough

I still remember the frustration like it was yesterday. It was June 2022, and I had 120 active listings on Poshmark. I was selling steadily, but not fast. I listed a Patagonia Synchilla fleece for $58 — great photos, strong keywords, good price.

But it sat. For 41 days.

Then one night, I decided to try something different. I crossposted it to eBay. It sold in less than 24 hours. Same listing. Same price.

That’s the moment everything changed. Instead of chasing “the perfect platform,” I started building a multi-platform reselling strategy — and the results snowballed.

Why Crossposting Matters for Resellers

Here’s where it gets interesting.

Most new resellers start on a single platform — Poshmark, eBay, Mercari, or Facebook Marketplace. It’s simple, and it works… for a while. But each platform has its own buyer base and search behavior.

• That Patagonia fleece didn’t move on Poshmark because the platform skews toward women’s apparel.

• On eBay, with its broader search base, it found the perfect buyer in less than a day.

Crossposting lets you:

• Tap into different audiences

• Increase sell-through without increasing sourcing

• Reduce dependency on one platform’s algorithm

• Keep your inventory moving

I often tell new sellers: crossposting isn’t “extra work” — it’s multiplying the reach of work you’ve already done.

How Crossposting Actually Works

Crossposting — or having your listings crossposted — means taking one product listing and publishing it on multiple platforms at the same time.

There are two ways to do it:

1. Manually: Copying and pasting images, titles, descriptions, and prices to each marketplace.

2. Using automation tools: Like Closo, List Perfectly, or Prime Lister to push listings out in one click.

I tried manual crossposting for two months back in summer 2022. It worked… but I burned out fast. When I switched to automation, my workflow went from 45 minutes per listing to under 5.

List Perfectly vs Closo vs Manual: My Real Results

To give you a sense of scale, here’s a snapshot of my numbers between July 2022 and March 2023:

The difference was staggering. And here’s the kicker — I wasn’t sourcing more. I was just making better use of what I already had.

The Best Platforms to Crosspost To (And Why)

When it comes to reselling products, not every platform performs the same. These are the marketplaces that consistently move the needle for me:

1. eBay — The Generalist Powerhouse

• Best for: Electronics, shoes, collectibles, vintage apparel

• Pros: Massive buyer pool, strong SEO, flexible pricing

• Cons: Fees are higher, and shipping is more complex

2. Poshmark — Fast for Apparel

• Best for: Clothing, accessories, shoes

• Pros: Easy listing flow, loyal buyer base

• Cons: Algorithm can be fickle, fees are flat but steep for lower-priced items

3. Mercari — Underrated and Surprisingly Fast

• Best for: Small electronics, home goods, lightweight fashion

• Pros: Easy shipping, simple interface

• Cons: Smaller buyer pool than eBay

4. Facebook Marketplace — Instant Local Demand

• Best for: Bulky or mid-price items (home goods, fashion, seasonal items)

• Pros: Local pick-up, no fees, fast response time

• Cons: Buyer reliability can be spotty

5. Depop — Trend-Driven Niche

• Best for: Y2K, vintage, streetwear

• Pros: Highly visual, younger buyer base

• Cons: Lower volume unless you target trends

I don’t list everywhere blindly. I target the platform where that specific product type has the best chance of moving fast. That’s why tools that make crossposting flexible are critical.

Spreading Too Thin Too Fast

When I first started crossposting in 2022, I tried pushing everything to five platforms at once. Sounds efficient, right? It wasn’t.

What happened:

• Inventory management got messy.

• I accidentally double-sold items.

• I couldn’t keep up with delisting.

• My buyer messages went unanswered for days.

That chaos nearly made me stop crossposting altogether. What fixed it was picking three core platforms (eBay, Poshmark, Facebook) and mastering my system before expanding.

Copying Descriptions Blindly

In my early days, I just copied and pasted titles and descriptions. No tweaks.

But different platforms prioritize different things:

• eBay buyers search by keywords.

• Poshmark buyers care more about style cues and brand.

• Facebook buyers respond best to clear, conversational titles.

Once I started tailoring descriptions even slightly, my conversion rate improved dramatically. For example:

• “Vintage Patagonia fleece pullover, men’s large” (eBay)

• “Patagonia Synchilla — Men’s L — Excellent Condition” (Poshmark)

• “Warm Patagonia fleece, barely used — pickup in Williamsburg” (Facebook)

That simple shift increased my overall sell-through rate by 19% in 60 days.

How I Actually Crosspost Today (Step-by-Step)

Here’s my personal workflow now. It’s taken me two years to refine, but it works.

1. Source & Photograph

   • I use a simple lighting setup and shoot square-format images to fit all platforms.

2. Draft Master Listing

   • I create a base listing in Closo (title, description, price).

3. Crosspost

   • With one click, I push it to eBay, Poshmark, and Facebook Marketplace.

4. Tweak Where Needed

   • Adjust title and description slightly per platform.

5. Automated Relisting

   • Closo auto-relists anything unsold after 14 days.

6. Track & Adjust

   • I use a spreadsheet to track time-to-sale and price adjustments.

Average time to list on 3 platforms: under 5 minutes per product.

The Best Reselling Apps to Make It Easy

I’ve tested almost every reselling app out there. These are the ones worth your time:

• Closo — Crossposting, relisting, pricing intelligence

• List Perfectly — Well-known, stable, but a bit clunky for large batches

• Vendoo — Clean interface, great for mid-volume sellers

• Prime Lister — Bulk relisting powerhouse

• Pirate Ship — Shipping labels for cross-platform orders

(And yes, I’ve canceled a few others that didn’t make the cut.)

Do I Need a Crossposting Tool to Start?

Short answer: No.

Long answer: Eventually, yes.

If you’re just testing the waters with 10–20 listings, manual crossposting is fine. But once you hit 50+, the time sink becomes real. I resisted automation for too long, and it cost me hundreds of hours over two years.

---

What Happens If I Sell the Same Item Twice?

This is a big one.

When your listings are crossposted, there’s always the risk of double-selling. I’ve done it — twice in one week, actually.

Solution:

• Use tools that auto-delist sold items from other platforms.

• If you’re doing it manually, check and delist daily.

• Keep inventory synced in one place (I use Closo’s dashboard for this).

---

Do All Products Perform the Same Everywhere?

Nope — and this is one of the biggest mistakes new resellers make.

Some categories are platform-native:

• Streetwear thrives on Depop.

• High-margin vintage apparel moves on Poshmark.

• Random household goods fly on Facebook.

• Electronics find their people on eBay.

Crossposting doesn’t mean blasting everything everywhere blindly. It means placing each product where it can shine.

90 Days, 386 Items, 1 Big Shift

In January 2023, I set a personal challenge:

• Crosspost 100% of my active inventory to 3 platforms

• Use automation to relist anything older than 14 days

• Track the results carefully

The results (90 days later):

• 386 items listed

• 211 items sold (55% sell-through)

• Average sale price: $37.80

• Weekly profit up 68% from the previous quarter

I didn’t source more. I didn’t hire help. I just got smarter about distribution.

Before vs After Crossposting

This is why crossposting changed my reselling business more than any sourcing strategy ever did.

A Few Honest Limitations to Keep in Mind

Crossposting isn’t a magic button. Here’s what I’ve learned the hard way:

• You will need to manage inventory carefully.

• You can’t rely on the same title/description everywhere.

• Some platforms have listing quirks (e.g., Facebook categories can be finicky).

• Automation tools have a learning curve.

But once the system is in place, the payoff is huge.

More Eyes, Faster Sales

Getting your listings crossposted is one of the smartest moves a serious reseller can make.

I started out thinking I needed to source more inventory to grow. In reality, I just needed to get my existing products in front of more buyers.

I use Closo to automate crossposting and relisting. It saves me about 3 hours weekly — time I now spend sourcing smarter, not working longer.
