One Month with Flyp

The $9 Cross-Listing App Every Reseller Is Talking About

A few years ago, I wrote an article comparing Sidekick Tools and PrimeLister. At the time, Sidekick completely changed the way I sold on Poshmark. It saved me hours of sharing and relisting, and it helped me stay consistent when life got busy.

Recently, I decided it was time to try something different.

For the past couple of years, most of my sales have come from Poshmark. While that's worked well, I wanted to branch out to other marketplaces like eBay, Mercari, and Depop. Managing listings across multiple platforms manually sounded exhausting, so I started looking into cross-listing software.

That's how I ended up trying Flyp.

I used Flyp for about a month and wanted to share what I liked, what frustrated me, and whether I think it's worth using.

Why I Wanted a Cross-Listing Tool

Like many part-time resellers, I'm always trying to make the most of my time. Between teaching online, substitute teaching, and maintaining my resale inventory, I don't have hours every day to create listings from scratch on multiple platforms.

My goal was simple: list once and have my inventory appear in as many places as possible.

What I Liked

The first thing that stood out was how easy it was to get started. Importing my existing listings was straightforward, and I appreciated that I could test the platform without committing to an expensive monthly subscription right away.

I was also impressed by the number of marketplaces supported. Being able to manage Poshmark, eBay, Mercari, Depop, Facebook Marketplace, and Etsy from one dashboard made the process feel much less overwhelming.

The automatic delisting feature was another benefit. When an item sells, keeping inventory synchronized across platforms is important. The last thing any reseller wants is to accidentally sell the same item twice.

What Frustrated Me

While Flyp helped simplify cross-listing, it wasn't perfect.

The biggest issue I encountered was staying connected to the various marketplaces. I found myself reconnecting accounts more often than I expected. It wasn't a deal breaker, but it did become annoying over time.

I also missed some of the sharing features I had become accustomed to with other tools. When I used Sidekick Tools, I felt like my closet stayed more active. With Flyp, the sharing functionality worked, but it didn't seem quite as effective for my particular store.

Another limitation is that Flyp works best from a computer. Since I occasionally manage listings from my phone, that took some adjustment.

One Lesson I Learned About eBay

If you're planning to cross-list to multiple platforms, I found it easier to create the listing on eBay first.

eBay generally requires more detailed information than Poshmark, including shipping weights and item specifics. Starting there meant I could transfer information elsewhere instead of having to go back and add missing details later.

That small change saved me time and reduced errors.

Would I Continue Using It?

After a month of testing, I can see why many resellers like Flyp.

It helped me expand beyond Poshmark, simplified the cross-listing process, and kept my inventory organized across multiple marketplaces.

At the same time, there are still a few features from other tools that I miss, particularly when it comes to sharing and account stability.

For now, I'll probably continue experimenting and comparing different tools to see what works best for my business.

Every reseller's needs are different, and the best software often depends on where you sell, how large your inventory is, and how hands-on you want to be.

As for me, my goal for 2026 is simple: continue growing my resale business and use the extra income to help pay down my student loans and car loan. Whether Flyp becomes a long-term part of that journey remains to be seen, but it has been an interesting tool to test.

Have you tried Flyp or another cross-listing platform? I'd be interested to hear what has worked for you.
