Cheapest with cloud auto-delist: Flyp ($9/mo) — but only 6 platforms. Best value at scale: SellerAider Pro ($29.99/mo) — 15+ platforms, cloud sync. Best mobile app + analytics: Vendoo ($31.98/mo with required add-on). Best for high-volume VA workflows: List Perfectly Pro Plus ($99/mo). Under 50 listings? Cross-list manually.
Here's the actual head-to-head. We verified pricing directly from each tool's pricing page in April 2026 and aggregated community sentiment from Trustpilot, Reddit (r/Flipping, r/poshmark, r/reselling), and Chrome Web Store reviews. Every comparison site in this space has commercial interest — including ours. We flag that bias throughout.
What Actually Matters in a Cross-Listing Tool
Auto-Delist Sync — And Whether It Runs Without You
When an item sells on Poshmark, how fast does it delist from eBay and Mercari? A lag of a few minutes is acceptable. "Eventually, maybe" means double-sells — canceled orders, bad reviews, and platform penalties. Automatic detection is non-negotiable for anyone with more than 50 active listings.
One architectural detail matters more than most comparisons acknowledge: extension-based auto-delist requires your computer to be on and your browser open. If your laptop sleeps overnight, sync stops. Cloud-based auto-delist (SellerAider Pro, PrimeLister Pro, Flyp, List Perfectly Pro Plus) runs on the vendor's servers regardless. For overnight double-sell protection, this distinction is the difference.
True Monthly Cost
Advertised prices are not always what you pay. Several tools gate key features — importing existing inventory, bulk delist/relist, all-marketplace access — behind add-on fees. A $20/month headline can become $32/month once you add the features required to actually use the tool. We show full-featured costs in the comparison below.
Cost-Per-Listing Comparison (April 2026)
| Tool | Monthly cost | 50 listings | 100 listings | 250 listings | 500 listings | Auto-delist |
|---|---|---|---|---|---|---|
| Flyp | $9 | $0.18 | $0.09 | $0.04 | $0.02 | Cloud ✓ |

FLIPSAIL not included — our own product; see section below for pricing and an honest assessment of limitations.
At 250 listings/month, SellerAider Pro ($0.12/listing, cloud auto-delist) and Crosslist Silver ($0.14/listing, no auto-delist) cost nearly the same. The auto-delist inclusion at equivalent price is the most concrete differentiator in the comparison — and no currently published review makes it directly.

Flyp Facebook Marketplace integration has documented reliability issues for some users; Vendoo Facebook Marketplace is partial/beta.
Vendoo
Vendoo is the market leader for a reason. It supports 11+ marketplaces, has a polished interface that needs no tutorial, and its mobile app is genuinely good — one of the only cross-listing tools with a real iOS/Android experience. The analytics dashboard tracks profit per item and per platform, with actual margin calculation if you enter cost of goods. No other tool in this comparison approaches Vendoo's analytics depth.
The real pricing picture: Base plans cap at 3 platforms. To unlock all marketplaces, importing, and bulk delist/relist, you need a $11.99/month add-on bundle. A Simple plan at $19.99/month becomes $31.98/month once you add it. No other tool in this comparison uses this add-on structure — it is the most-cited complaint in user reviews and has been described as a "baggage fee model" in community discussions.
Auto-delist caveat: Vendoo's auto-delist runs through its Chrome extension and requires your computer to remain on and the browser open. It also covers only 5 platforms (eBay, Poshmark, Depop, Mercari, Whatnot) — not all 11+ supported marketplaces. When eBay or Poshmark pushes a front-end update, the extension typically breaks for 4-72 hours. Multiple users report overnight double-sales when the extension stops monitoring.
- Pricing: Simple $19.99/mo (3 platforms) + $11.99/mo add-on bundle for full features = $31.98/mo; Plus $41.98, Pro $61.98
- Platforms: 11+ including Poshmark, eBay, Mercari, Depop, Etsy, Grailed, Whatnot, Vinted, Vestiaire Collective, Facebook Marketplace, Shopify
- Strengths: Best mobile app, best analytics (profit + margin tracking), intuitive UI, Whatnot support, broadest platform list
- Weaknesses: Add-on model inflates real cost; extension-based auto-delist (computer must stay on, 5-platform limit); breaks during marketplace UI updates
- Best for: Mid-volume sellers (100-500 listings) who need the mobile app, Whatnot support, or the analytics dashboard and will pay for polish
List Perfectly
List Perfectly is the power-user tool. Its bulk editing is unmatched — update the price on 200 listings across four platforms in one action. Pricing has not changed since 2019, an unusual commitment in SaaS. Human support runs 7 days a week including holidays, and the community ecosystem (live events, onboarding sessions, Facebook groups) is the strongest in the category.
The $29 Simple plan is not viable for real selling. It only transfers title, description, and price — no color, brand, size, quantity, SKU, or condition. Missing those fields on eBay directly hurts search ranking. Most sellers who start at $29 upgrade within the first week. The effective entry price for a usable setup is $49 (Business) or $69 (Pro).
Auto-delist is gated at $99+/month. The $69 Pro plan only sends sale detection alerts — you still delist manually. If auto-delist matters, the relevant comparison is LP Pro Plus ($99) vs. SellerAider Pro ($29.99) or PrimeLister Pro ($49.99), both of which include cloud auto-delist.
- Pricing: $29/mo (Simple — missing critical fields), $49/mo (Business), $69/mo (Pro, no auto-delist), $99+/mo (Pro Plus, cloud auto-delist)
- Platforms: Poshmark, eBay, Mercari, Depop, Etsy, Grailed, Facebook Marketplace, Vestiaire Collective, Shopify, Instagram
- Strengths: Best bulk editing, unlimited listings at all tiers, stable pricing since 2019, 7-day human support, strong community
- Weaknesses: $29 plan unusable; auto-delist only at $99+; opens a separate browser tab per marketplace (slow at scale); steep learning curve
- Best for: High-volume sellers (500+ listings) who need bulk operations and sub-accounts for VA workflows; not cost-competitive for auto-delist below $99
Crosslist
Crosslist has arguably the cleanest crosslisting UX in the category. A single dynamic form covers all 11 marketplaces — fill once, post everywhere. International support (US, UK, Canada, Australia) with automatic size conversion across locales. Bronze at $29.99/month covers 200 listings; Silver at $34.99 covers 500. The 4.6 Trustpilot rating (720+ reviews) reflects a genuinely well-built product.
Crosslist has no inventory sync or auto-delist functionality on any plan — Bronze through Diamond — as of April 2026. When an item sells, you must manually remove it from every other marketplace. At 100+ active listings across 5 platforms, that is 500+ listing instances to manage manually. Double-selling incidents are the most-cited reason sellers switch away from Crosslist in community discussions. Verify this against your own use case before subscribing.
- Pricing: $29.99/mo (Bronze, 200 listings), $34.99/mo (Silver, 500), $39.99/mo (Gold, 1,000), $44.99/mo (Diamond, unlimited)
- Platforms: Poshmark, eBay, Mercari, Depop, Etsy, Facebook Marketplace, Vinted, Grailed, Whatnot (11 total)
- Strengths: Cleanest single-form UX in the category, full international coverage with auto size conversion, competitive per-listing cost at volume
- Weaknesses: Zero auto-delist on any plan; desktop Chrome only; no analytics or profit tracking
- Best for: Sellers who actively monitor sales across platforms and want the fastest crosslisting workflow; not viable for high-volume sellers without vigilant manual delisting
Flyp
Flyp is the cheapest paid option in the category — $9/month flat after a 100-day free trial (no credit card required). Unlimited listings, cloud auto-delist, and a Poshmark sharing bot are all included. In the cost-per-listing analysis, Flyp wins at every volume tier: $0.18/listing at 50/month, $0.02/listing at 500/month. No other tool is close. The constraint is platform coverage: Flyp supports only 6 platforms (Poshmark, eBay, Mercari, Depop, Whatnot, Facebook Marketplace). No Etsy, no Vinted, no Grailed. The Facebook Marketplace integration also has documented JSON parsing errors for some users.
- Pricing: 100-day free trial (no credit card), $9/mo paid — unlimited listings, all features included
- Platforms: Poshmark, eBay, Mercari, Depop, Whatnot, Facebook Marketplace (6 total; no Etsy, Vinted, or Grailed)
- Strengths: Cheapest option by a large margin, cloud auto-delist included, Poshmark sharing bot bundled, longest free trial in the category
- Weaknesses: Only 6 platforms; no bulk crosslisting (processes one at a time); Facebook Marketplace integration unreliable for some users
- Best for: Budget-conscious sellers whose platform mix is fully covered by the 6 supported marketplaces
SellerAider
SellerAider has the broadest platform coverage in this comparison — 15+ marketplaces including UK/EU-specific platforms like Vinted, Shpock, and Vestiaire Collective that most US-centric tools do not support. Pricing is flat: Standard at $12.99/month (no auto-delist, 15+ platforms) and Pro at $29.99/month with cloud-based auto-delist. No add-ons, no per-listing caps at either tier.
- Pricing: $12.99/mo (Standard, 15+ platforms, no auto-delist), $29.99/mo (Pro, cloud auto-delist)
- Platforms: 15+ including Poshmark, eBay, Mercari, Depop, Etsy, Grailed, Vinted, Shpock, Vestiaire Collective, and other UK/EU marketplaces
- Strengths: Broadest platform coverage, cloud auto-delist at Pro tier, flat pricing with no add-ons, UK/EU marketplace support
- Weaknesses: Fewer independent reviews and community resources than incumbents; rating largely self-curated on their own site
- Best for: International sellers or anyone needing Vinted, Grailed, and Etsy alongside the standard US platforms; best value with cloud auto-delist at any volume above 100 listings
PrimeLister
PrimeLister's main differentiator is cloud-based auto-delist on a clean two-plan structure. The Pro plan at $49.99/month covers 8 marketplaces with genuine cloud auto-delist — it runs without your computer on, which is a meaningful operational advantage over extension-based competitors. Strong Poshmark automation (sharing, relisting, offers to likers) is also included.
Important naming issue: The "$29.99 Crosslisting Basic" plan supports only a single marketplace — it is not a crosslister. Actual multi-platform crosslisting requires the $49.99 Pro plan, a 67% price increase from the entry-level name. This has generated documented frustration in G2 reviews and Reddit threads. Coverage is US/Canada/Australia only — no UK or EU support.
- Pricing: $29.99/mo (Crosslisting Basic — one marketplace; misleading name), $49.99/mo (Pro, 8 platforms, cloud auto-delist)
- Platforms: Poshmark, eBay, Mercari, Depop, Etsy, Facebook Marketplace, Grailed, Whatnot (8 total, US/CA/AU only)
- Strengths: Cloud auto-delist included in Pro, simple two-plan structure, strong Poshmark sharing and automation
- Weaknesses: "Crosslisting Basic" plan name is misleading (single marketplace only); no UK/EU support; cancellation button reportedly hidden behind live chat
- Best for: Sellers who want cloud auto-delist at a mid-tier price without needing UK/EU platforms
FLIPSAIL
Full disclosure: this is our product. FLIPSAIL takes a different approach — it is a browser extension, not a web app. It works directly inside each marketplace's website, automating actions the way you would do them manually: sharing on Poshmark, sending offers, repricing, and cross-listing.
The advantage is breadth of automation. Cross-listing is one piece of a larger toolkit. You do not need a separate sharing bot, a separate repricing tool, and a separate cross-lister — FLIPSAIL handles the post-listing work that dedicated cross-listing tools ignore. The disadvantage is platform count: as of April 2026, we support Poshmark, eBay, Mercari, Depop, and Etsy. No Grailed, Vinted, or Whatnot yet. No mobile app for cross-listing — desktop Chrome only.
- Pricing: Free tier available, $15/mo (Standard), $30/mo (Pro)
- Platforms: Poshmark, eBay, Mercari, Depop, Etsy (5 platforms)
- Strengths: Automation beyond cross-listing (sharing, offers, repricing), lower price point, works directly in marketplace sites
- Weaknesses: Fewer platforms (5), desktop-only, cross-listing flow less polished than dedicated tools, no centralized inventory dashboard
- Best for: Sellers who want one tool for cross-listing AND daily automation rather than paying for separate tools
Nifty
Nifty leads with AI listing generation. Upload photos, and it produces a complete listing — title, description, measurements, and suggested pricing based on comparable sales. In our testing, it correctly identified brands and categories around 80% of the time on standard clothing. It struggles with vintage and niche items.
As a cross-listing tool, it supports only 4 platforms (Poshmark, eBay, Mercari, Depop — no Etsy or Facebook Marketplace). The pricing is steep at $39.99-89.99/month for cross-listing plans, which is hard to justify if AI listing generation is not your main bottleneck.
- Pricing: 7-day free trial; Crosslisting Plus $39.99/mo, Crosslisting Pro $59.99/mo; Bundle Plus $69.99/mo, Bundle Pro $89.99/mo
- Platforms: Poshmark, eBay, Mercari, Depop (4 total)
- Strengths: Best AI listing generation in the category, good photo-to-listing workflow, saves time on description writing
- Weaknesses: AI accuracy inconsistent on niche/vintage items, only 4 platforms (no Etsy or Facebook Marketplace), expensive relative to platform count
- Best for: High-volume sellers whose bottleneck is writing listing descriptions, not cross-posting
Manual Cross-Listing (The Free Option)
Under 50 listings across 2 platforms? Manual is genuinely viable. Open both, copy your listing details, adjust for platform differences, post. It takes 5-10 minutes per item and costs nothing.
The math changes at scale. At 100 listings across 3 platforms, manual setup costs you 8-12 hours — plus ongoing time monitoring each platform for sales. At 200+ listings, the time cost exceeds the subscription cost of any tool on this list.
- Pricing: Free
- Platforms: Whatever you can open in a browser
- Strengths: No cost, full control, no dependency on a third-party tool
- Weaknesses: Extremely time-intensive at scale, no automatic inventory sync (double-sell risk), no analytics
- Best for: Sellers with fewer than 50 listings, or high-value/low-volume sellers where per-item attention matters more than speed
Red Flags: What to Verify Before Subscribing
<strong>1. Extension vs. cloud auto-delist.</strong> Vendoo's auto-delist stops when your computer sleeps. Cloud-based auto-delist (SellerAider Pro, PrimeLister Pro, Flyp, List Perfectly Pro Plus) runs independently. If you sell overnight, this distinction matters. <strong>2. Crosslist has no auto-delist on any plan.</strong> This is consistent across all four tiers as of April 2026. At 100+ active listings across 5 platforms, that is 500+ instances to manage manually. <strong>3. List Perfectly's $29 plan is missing critical fields.</strong> No brand, size, color, SKU, or condition. The effective entry price for a usable setup is $49–$69. Most sellers who start at $29 upgrade within their first week. <strong>4. PrimeLister's "Crosslisting Basic" is not a crosslister.</strong> The $29.99/mo plan supports only one marketplace. Actual crosslisting requires the $49.99 Pro plan.
How to Decide Which Tool Fits Your Business
By Listing Volume
- Under 50 listings: Manual. Do not pay for a tool until volume justifies it. If you want a risk-free test, Flyp's 100-day no-card trial is the lowest-friction entry in the category.
- 50-150 listings: Flyp ($9) if your platform mix fits its 6 supported marketplaces. SellerAider Standard ($12.99) if you need Etsy, Vinted, or Grailed — no auto-delist but broadest coverage at the lowest price. Vendoo if you need the mobile app.
- 150-300 listings: SellerAider Pro ($29.99 flat, cloud auto-delist, 15+ platforms) is the best value. Crosslist Silver ($34.99) is cost-competitive but has no auto-delist. Vendoo Plus with add-ons ($41.98) adds analytics and Whatnot if those matter.
- 300-600 listings: SellerAider Pro ($0.06/listing at 500) with cloud auto-delist wins on cost. Vendoo Pro ($61.98) justifies itself if analytics and the mobile app are core to your workflow. List Perfectly Pro Plus ($99) if you use VAs or manage multiple accounts.
- 600+ listings: Vendoo Unlimited or List Perfectly Pro Plus. At this volume, bulk tools, sub-accounts, and support SLA matter more than per-listing cost.
By Primary Need
- Lowest cost with auto-delist: Flyp ($9/mo) — if your platforms are covered.
- Broadest platform coverage: SellerAider (15+ platforms including UK/EU).
- Best analytics and mobile app: Vendoo — no other tool in this comparison comes close.
- Maximum bulk operations: List Perfectly Pro Plus — sub-accounts and bulk edit at scale.
- Cross-listing + daily automation in one tool: FLIPSAIL — sharing, offers, repricing, and cross-listing.
The Total Cost Calculation
Also factor in time cost. If Tool A costs $50/month but saves you 8 hours compared to Tool B at $29/month, and your time is worth more than $2.60/hour (it is), Tool A is cheaper. The subscription fee is the visible cost. Time is the hidden one.
Frequently Asked Questions
Crosslist vs Flyp: which is better?
Flyp is cheaper ($9/mo vs $29.99/mo for Crosslist Bronze) and includes cloud auto-delist that Crosslist lacks on every plan. Crosslist supports more platforms (11 vs 6) and has a cleaner single-form crosslisting UX. Pick Flyp if your platforms are Poshmark, eBay, Mercari, Depop, Whatnot, or Facebook Marketplace. Pick Crosslist only if you need Etsy, Vinted, or Grailed support and you commit to manual delisting on every sale.
Vendoo vs Flyp: how do they compare?
Flyp wins on price ($9 flat vs Vendoo at $31.98 with the required add-on bundle) and on auto-delist reliability (Flyp uses cloud sync, Vendoo uses an extension that stops when your computer sleeps). Vendoo wins on platform count (11+ vs Flyp's 6), the mobile app (Vendoo has a real iOS/Android app, Flyp does not), and analytics (Vendoo tracks profit and margin; Flyp does not). For a budget-conscious seller on the 6 supported platforms, Flyp; for a mid-volume seller who needs mobile and Whatnot, Vendoo.
Flyp vs List Perfectly: which one wins?
Flyp is dramatically cheaper ($9/mo vs $69-99/mo for List Perfectly with auto-delist) and includes cloud auto-delist at the entry price. List Perfectly wins on bulk operations (best in the category), platform coverage (10 vs 6), VA support with sub-accounts, and 7-day human support. For sellers under 300 listings, Flyp is hard to beat on value. For 500+ listings with VA workflows, List Perfectly Pro Plus is worth the price gap.
Crosslist vs PrimeLister: what is the difference?
PrimeLister Pro ($49.99/mo) includes cloud auto-delist; Crosslist has no auto-delist on any plan. Crosslist supports 11 platforms (including Vinted) vs PrimeLister's 8 (US/CA/AU only). PrimeLister has stronger Poshmark sharing/automation built in. The biggest landmine: PrimeLister's "Crosslisting Basic" plan at $29.99 only covers ONE marketplace — it is not a crosslister despite the name. Real crosslisting requires Pro at $49.99.
Crosslist vs List Perfectly: which is better?
Crosslist is cheaper at every tier ($29.99-$44.99 vs $29-$99 for List Perfectly with usable features) and has a cleaner crosslisting form. List Perfectly has stronger bulk operations, sub-account support for VAs, and the longest pricing stability in the category (no increases since 2019). Neither has cloud auto-delist on the entry plan — Crosslist has none on any plan; List Perfectly's Pro Plus at $99 has it. For solo sellers, Crosslist; for VA-supported high-volume operations, List Perfectly.
How much does Crosslist cost?
Crosslist has four tiers as of April 2026: Bronze $29.99/mo (200 listings), Silver $34.99/mo (500), Gold $39.99/mo (1,000), and Diamond $44.99/mo (unlimited). All tiers cover the same 11 platforms. Critically, no Crosslist plan includes auto-delist — when an item sells, you must manually remove it from every other marketplace. Free trials are 7 days.
What are the best Flyp alternatives?
For broader platform coverage: SellerAider Standard ($12.99/mo, 15+ platforms, no auto-delist) or SellerAider Pro ($29.99/mo, 15+ platforms with cloud auto-delist). For better analytics and a mobile app: Vendoo ($31.98/mo with add-on). For Etsy and Grailed support that Flyp lacks: Crosslist Bronze ($29.99/mo) or List Perfectly Business ($49/mo). FLIPSAIL ($15-30/mo) is a middle option — fewer platforms (5) but adds daily automation (sharing, offers, repricing) that Flyp does not.
What is the difference between cloud-based and extension-based auto-delist?
Extension-based auto-delist (Vendoo) runs through a Chrome browser extension — if your computer sleeps, the browser closes, or you restart, sync stops. Cloud-based auto-delist (SellerAider Pro, PrimeLister Pro, Flyp, List Perfectly Pro Plus) runs on the vendor's servers independently of your computer. For overnight protection against double-sells, cloud-based is meaningfully more reliable.
How long does it actually take to cross-list an item with a tool?
With a dedicated cross-listing tool like Vendoo or Crosslist, pushing an existing listing to 2-3 additional platforms takes 2-4 minutes once you are familiar with the workflow. The first few items take longer while you map fields and learn the tool — budget 10-15 minutes per item for your first week. At steady state, cross-listing adds roughly 3 minutes per item, compared to 15-25 minutes if you list on each platform from scratch.
What happens to my existing listings if I switch cross-listing tools?
Switching tools does not automatically migrate your inventory history. Most tools let you import existing listings by scanning your active marketplace listings, but the new tool will not have your sales history or the original listing data it did not create. Plan for 2-4 hours to re-sync a 200-listing inventory when switching, and overlap both tools for a week to avoid inventory sync gaps during the transition.
Does cross-listing the same item to multiple platforms hurt your search ranking on each one?
No — each marketplace indexes its own listings independently and has no visibility into what you post elsewhere. Poshmark does not penalize you for also listing on eBay, and vice versa. Platform search ranking is determined by your activity within that platform (shares, recency, seller reputation), not by whether you sell on competitors.
Do I pay platform selling fees on every platform where an item is listed, or only where it sells?
You only pay selling fees on the platform where the item actually sells. Listing on Poshmark, eBay, and Mercari simultaneously costs nothing upfront — each platform's 13-15% fee applies only to the one sale that goes through. Cross-listing does not multiply your fee exposure; it multiplies your chances of a sale at no additional cost until something sells.
