How to Crosspost on Facebook Without Losing Your Mind (Quick Overview Included)

How to Crosspost on Facebook Without Losing Your Mind (Quick Overview Included)

Introduction

The first time I listed something on Facebook Marketplace wasn’t some grand strategy moment — it was a $45 IKEA Kallax shelf I didn’t need anymore. Within three hours, a young couple showed up, cash in hand. That was March 2021.

At the time, I had no idea what “crossposting” even meant. I was just someone selling extra furniture. Fast forward to late 2022, and I’d become one of those poshers (you know the type — constantly listing, cross listing, tweaking photos, tracking margins).

The biggest leap wasn’t more stuff — it was figuring out how to crosspost my listings on Facebook efficiently without losing track of what sold where. That skill has made my little reselling side hustle into a reliable income stream.

Here’s exactly how I did it — including the missteps that cost me sales.

Why Learning How to Crosspost on Facebook Matters

Most people think Facebook Marketplace is just a place to dump old furniture. But for serious resellers, it’s one of the most liquid marketplaces in the U.S. — 1 in 3 adults uses Marketplace monthly.

For me, Facebook is where inventory moves fast. I once sold a $220 Patagonia parka that had sat on Poshmark for 47 days — in less than 24 hours on Marketplace.

Crossposting isn’t just duplicating listings. It’s a workflow:

  • Centralizing your inventory

  • Copying or syndicating listings

  • Tracking what’s sold

  • Delisting automatically when something moves

But — and this is a big but — if you do it manually without a system, it’s a mess. I learned this the hard way in August 2022 when I double-sold a rare pair of On Cloud sneakers. One on eBay. One on Facebook. Both in 12 hours. Refunds and apologies followed.

The Tools I Tried for Crossposting

Between 2022 and 2024, I tested five tools for crossposting:

  • Closo — my current go-to for Poshmark + eBay + Facebook (auto-delist saves me at least 3 hours weekly).

  • Vendoo — good starter, clean UI, but Facebook integration was slower in early 2023.

  • List Perfectly — lots of flexibility, though I found it buggy with Facebook in late 2022.

  • ResellKit — smooth UX, but missing some automation features.

  • Manual spreadsheet + PhotoRoom — what I started with.

If you’re just reselling stuff casually, manual might work. But once I passed 100 active listings, automation wasn’t optional anymore.

Step-by-Step: How to Crosspost on Facebook Marketplace

This is the exact process I use today. It’s not the only way — but it’s the one that’s made me consistent, profitable, and (mostly) sane.

1. Choose the right items to crosspost

I don’t crosspost everything. Items under $15 usually aren’t worth the extra handling. But:

  • Branded apparel (Patagonia, Levi’s, Carhartt)

  • Home goods (West Elm, IKEA, Anthropologie)

  • Small electronics
    — these move fast on Facebook.

2. Clean and prep your photos

I edit every image through PhotoRoom (I once used an etsy coupon to get their premium version for free in August 2022 — a small but smart hack).

Clean photos = more messages = faster sales.

3. Write universal titles and descriptions

You don’t need platform-specific language. I keep titles clean:

  • “Patagonia Nano Puff Jacket Women’s M — Excellent Condition”

  • No hashtags, no all caps.

Descriptions: condition, size, shipping or pickup. That’s it.

4. Use your crossposting software

I bulk upload to Closo, then push to Facebook Marketplace + Poshmark + eBay. I set my pickup or shipping settings once and apply it across listings.

This dropped my per-listing time from 12 minutes to under 2.

5. Track sales and delist fast

The tricky part isn’t posting. It’s delisting when something sells elsewhere.
When I was doing it manually in summer 2022, I double-sold six items in two months. Now, Closo auto-delists within 5 minutes. That changed everything.

How to See Sold Items on Facebook Marketplace

People always ask me: “How do you see what sold on Facebook Marketplace?”

Here’s something everyone should know: Facebook doesn’t always make this intuitive.

The simplest way:

  • Go to Marketplace

  • Tap Your Account

  • Tap Your Listings

  • Filter by Sold.

You’ll see exactly what’s moved and when. This is crucial if you’re crossposting manually — because if you don’t delist elsewhere after something sells on Facebook, you’re asking for inventory chaos.

(Parenthetical aside: early on, I thought Facebook “just handled this automatically.” It doesn’t. At all.)

How Poshers Use Facebook Marketplace Differently

Poshers (aka Poshmark power sellers) treat Facebook Marketplace like an acceleration channel. They don’t just copy listings over — they use it strategically:

  • For faster-moving seasonal inventory (UGG boots in December, linen in May)

  • For testing pricing before pushing to Poshmark or eBay

  • For tapping local buyers to avoid shipping fees

In February 2023, I crossposted 60 items from Poshmark to Facebook. Twenty-two sold on Facebook within 9 days. Same inventory. Same photos. Different velocity.

Here’s where it gets interesting: Facebook buyers often negotiate less aggressively than eBay buyers, in my experience. That’s why I keep Facebook as a front-line sales channel.

Honest Failures Along the Way

If it sounds too smooth, it wasn’t.

  • April 2022: I forgot to delist a Patagonia hoodie after it sold on Facebook. eBay buyer filed a complaint. Refund and a ding on my metrics.

  • October 2022: I over-automated. Pushed every listing to every channel — including low-margin junk. I ended up wasting time dealing with low-value pickups.

  • June 2023: Marketplace temporarily limited my shipping access after too many edits. Manual backup saved me.

The point: Crossposting isn’t foolproof. There’s friction. But once I built in the right checks (good software, sales alerts, tighter SKUs), the returns outweighed the chaos.

Facebook vs Other Marketplaces — My Real Numbers

Platform Average Days to Sell Average Fee Avg. Sale Price Automation
Facebook Marketplace 2.7 days 0% (local) $48 High
Poshmark 8.1 days 20% $56 High
eBay 6.3 days ~13% $52 High

These numbers are from Jan–Sept 2023 across 367 listings. Your mileage will vary — but Facebook consistently drives faster first sales for me.

Common Question I See: “How Do You Keep Track of It All?”

Here’s something everyone wants to know: how do you keep from losing track when crossposting?

When I had under 50 listings, I used a spreadsheet. Columns: SKU, platform, date listed, sale date, pickup or ship. Simple.

Once I crossed 150 listings in May 2023, I switched fully to Closo. It auto-syncs my listings and removes sold items from other platforms. I still keep a lightweight SKU sheet, but I’m not manually delisting anymore.

If you’re not ready for software, the key is discipline. One sale = update every platform within 15 minutes.

Common Question I See: “Can You Crosspost Everything?”

No — and honestly, you shouldn’t.

Facebook Marketplace has its own quirks: shipping rules, item category limits, occasional random listing rejections. I’ve found that bulky, mid-price, or brand-name apparel performs best. Highly niche collectibles? Less so.

That’s why I still use eBay for long-tail inventory (like vintage film cameras) and Facebook for high-velocity flips.

People Always Ask Me: “What About Coupons or Discounts?”

Ah yes — the etsy coupon hack. Not for Facebook itself, but for tools.

In 2022, I used an Etsy coupon to get PhotoRoom Premium free for 2 months. That saved me ~$40 and gave me clean, professional-looking photos that boosted conversions.

If you’re bootstrapping your reselling operation, those small wins matter more than they seem.

My Honest Take: Crossposting Works — But It’s Work

I’m not going to say this is a “passive income” trick. It’s not.

Crossposting on Facebook has been my single best lever for turning random stuff into actual, trackable cash flow. In 2023 alone, 41% of my total resale revenue came from Facebook Marketplace. But it took:

  • Learning how to see sold items on Facebook Marketplace

  • Setting up solid automation

  • Accepting some hiccups along the way

I use Closo to automate crossposting and delisting — saves me about 3 hours weekly. That time now goes into sourcing better inventory, not clicking through tabs.
