Crosslist from Wix to Whatnot — FLUF Connect
List your Wix catalogue on Whatnot — reach the world's fastest-growing live shopping marketplace with automatic crosslisting and inventory sync via FLUF Connect.
Key Takeaways — Wix to Whatnot
- Wix is a hosted website-builder store — ideal for owning your brand and customer data, but it cannot natively list to live commerce and collectibles platforms without a crosslisting tool.
- Whatnot is the world’s largest live shopping marketplace, recording $8 billion in GMV in 2025 — more than double its 2024 figure source. Over 20 million new accounts joined in 2025, and Whatnot is now live for sellers in the US, UK, Canada, Australia, France, Germany, Austria, Netherlands and Belgium source.
- Whatnot fees are 8% commission on items up to $1,500 (0% on amounts above $1,500) plus 2.9% + $0.30 payment processing per transaction. UK and EU sellers pay 6.67% + VAT plus 2.42% + £/€0.25 processing source.
- Live streaming first, fixed price also available — Whatnot is built around live video auctions, but sellers can also list items at fixed prices for asynchronous buyers. FLUF Connect crosslists your Wix products to Whatnot’s fixed-price catalogue, making your inventory available to buyers browsing between shows.
- Best categories on Whatnot: sports cards (#1 by volume), trading card games (Pokémon, Magic: The Gathering), collectibles, sneakers, vintage clothing, and women’s fashion (growing 223% year-over-year in 2025) source.
- FLUF Connect crosslists from Wix to Whatnot via the browser extension, with inventory sync, sold-status updates and order tracking. Plans start at £19/month (Growth — 500 products). There is no free plan.
Why Sell on Both Wix and Whatnot?
Pairing Wix with Whatnot brings together an owned-channel brand store and the fastest-growing live commerce ecosystem in the world. Your Wix store gives you a permanent branded storefront where customers can buy at any time and where you own the customer relationship. Whatnot adds a live, event-driven discovery channel where tens of millions of engaged buyers come to watch, bid and buy in real time — often impulse-purchasing items they would not have found through conventional search.
The growth data for Whatnot in 2025 is extraordinary by any standard: $8 billion in GMV (more than doubling from $3 billion in 2024), 20 million+ new accounts created in a single year, 285% year-on-year growth in new buyers, and average session times of 95 minutes per day per user source. No other resale marketplace in the FLUF ecosystem grew at this rate in 2025. For sellers with inventory in Whatnot’s core categories, this growth translates directly into buyer opportunity.
Whatnot’s expansion beyond the United States has also accelerated. Sellers in the UK, Canada, Australia, France, Germany, Austria, Netherlands and Belgium can now go live and reach both local and global audiences — Whatnot ranked as the #1 Shopping app in both the US and UK in 2025. For UK-based Wix sellers with collectibles, sports cards, trading card games or fast-growing fashion categories, Whatnot is no longer an American-only opportunity.
| Factor | Wix | Whatnot |
|---|---|---|
| Platform scale | Your own traffic — you acquire every visitor | $8B GMV 2025; 20M+ new accounts in 2025 source |
| Geographic focus | Global — wherever you market to | US, UK, Canada, Australia, France, Germany, Austria, Netherlands, Belgium source |
| Commission (US) | No platform commission; ~2.1% + £0.20 card processing via Wix Payments source | 8% on items up to $1,500 (0% above); + 2.9% + $0.30 processing source |
| Commission (UK) | No platform commission | 6.67% + VAT + 2.42% + £0.25 processing |
| Top categories | Any product type | Sports cards, TCG (Pokémon/MTG/Yu-Gi-Oh!), collectibles, sneakers, vintage clothing, women’s fashion, beauty |
| Discovery model | SEO, paid ads, social — you drive traffic | Live shows, category feeds, curated drops, followed-seller notifications |
Who this pair suits. Whatnot is a strong second channel for Wix sellers with inventory in Whatnot’s core categories: sports memorabilia and trading cards are the highest-volume by far, but women’s fashion, vintage clothing, sneakers, beauty and jewellery are all growing rapidly. If your Wix store specialises in any of these areas, Whatnot offers access to a buyer base that is already in purchase mode and actively engaging with sellers in your category. Sellers in the US with Pokemon cards, graded sports cards, sneakers and streetwear will find the most established buyer communities; UK sellers are joining a fast-growing regional Whatnot community that ranked the app #1 in Shopping in 2025.
Fixed-price listings vs live shows. Whatnot is primarily a live streaming platform — sellers go live on video, present items on camera, and buyers bid in real time. This is a meaningful time commitment and a distinct selling skill from running an online store. However, Whatnot also supports fixed-price listings that appear in category browse and search between shows, allowing buyers to purchase without waiting for a live event. FLUF Connect crosslists your Wix products to Whatnot’s fixed-price catalogue — you gain Whatnot’s buyer reach without running live shows. Going live is an optional additional distribution layer, not a requirement for selling on the platform via FLUF.
How Whatnot’s Live Commerce Model Works
Whatnot is fundamentally a live video shopping platform, and understanding how it works helps Wix sellers decide how to integrate it into their workflow — whether that is passive fixed-price listing via FLUF, active live selling, or both.
Sellers on Whatnot host scheduled live video shows from the Whatnot mobile app or Seller Hub. Shows appear in category feeds and on the Whatnot homepage where buyers browse in real time. During a show, sellers display items on camera — typically in a specific category like “Sports Cards” or “Women’s Vintage” — and buyers bid using the app’s bid interface. When a countdown timer reaches zero, the highest bidder’s saved payment method is automatically charged. A new bid extends the timer by a few seconds, creating the auction tension that drives engaged bidding source. Payments are released to sellers 2–3 business days after tracking updates.
Beyond live shows, Whatnot also supports fixed-price listings — items listed with a set “Buy it now” price that buyers can purchase at any time, whether or not the seller is live. These fixed-price listings appear in category search and browse between shows, capturing buyers who are shopping outside of live show hours or in categories where no show is currently live. FLUF Connect crosslists your Wix products to these fixed-price listings, giving you Whatnot distribution without requiring you to go live.
Why 95 minutes of session time matters. Whatnot users spend an average of 95 minutes per day on the platform — among the highest engagement metrics of any e-commerce app source. This means buyers are not clicking in and out quickly; they are watching shows, browsing categories and discovering items over extended browsing sessions. Fixed-price listings benefit from this extended dwell time: a buyer who is already 45 minutes into watching a sports cards show and browsing between auctions is primed to discover and buy a fixed-price listing in the same category. Your crosslisted Wix products sit in this high-engagement browse environment without you needing to run a show yourself.
Growing Categories on Whatnot for Wix Sellers
Whatnot’s 2025 State of Live Selling report reveals which categories are growing fastest, offering practical guidance on where Wix store inventory is most likely to convert on the platform.
Sports Cards and Trading Card Games. These remain Whatnot’s core and largest categories by volume — 6.4 million+ sports cards are sold per month in the US alone. Pokémon cards are the single most searched TCG product, with graded Pokémon search volumes up 255% in 2025 and a record $660,000 Caitlin Clark rookie card sale illustrating the high ceiling for premium pieces. If your Wix store carries any sports memorabilia or trading cards, Whatnot is the highest-concentration buyer base for these items anywhere online.
Women’s Fashion. Women’s fashion grew 223% year-on-year on Whatnot in 2025 — the second-fastest-growing major category on the platform. Vintage clothing, premium resale and brand-name fashion all perform well. For Wix store owners with women’s fashion catalogues, this growth makes Whatnot a meaningfully different distribution option from what it was 18 months ago.
Beauty and Electronics. Beauty grew 791% in 2025 (albeit from a smaller base) and Electronics 444%. These categories are earlier in their Whatnot lifecycle — the buyer communities are smaller than cards/TCG, but growing very quickly. For Wix sellers in these categories, first-mover advantage on Whatnot’s expanding buyer base is a real consideration.
Jewellery and Sneakers. Jewellery searches grew 259% in 2025. Sneakers — particularly limited editions and collaborations — have an established Whatnot seller community with buyers who understand and pay for the rarity premium.
Crosslisting from Wix to Whatnot: Before and After FLUF Connect
Manually crosslisting a Wix product to Whatnot as a fixed-price listing means downloading photos, navigating Whatnot’s listing form, entering title, description, category, condition and price, and then monitoring both platforms when items sell. FLUF removes the manual listing step entirely.
- Download product photos from your Wix dashboard.
- Open Whatnot’s listing tool, select the appropriate category and sub-category.
- Upload photos in the required sequence.
- Enter title, description, condition, price and any category-specific details (e.g., grading info for cards).
- Publish as a fixed-price listing. Note listing for future reference.
- Monitor both Wix and Whatnot; manually update stock when either channel makes a sale.
With FLUF Connect, steps 1–5 are replaced by a bulk crosslist action. Step 6 (inventory sync) runs automatically when a Whatnot sale lands. You invest time in your listing catalogue quality and potential show strategy rather than mechanical duplication of data entry.
Time saved
At around 10–15 minutes per manual Whatnot fixed-price listing, a 50-item crosslist from Wix takes 8–12 hours to list manually. FLUF Connect completes the same batch in under an hour, with inventory sync running automatically from that point.
How to Crosslist from Wix to Whatnot with FLUF Connect

What Transfers When You Crosslist from Wix to Whatnot?
| Wix field | Whatnot field | Transfer status | Notes |
|---|---|---|---|
| Product title | Listing title | ✅ Automatic | For collectibles: brand + set name + card name/number + condition grade performs best in Whatnot search. |
| Description | Description | ✅ Automatic | Condition details, grading info and provenance are important for cards and collectibles buyers. |
| Images | Photos | ⚡ Smart mapped | Multiple scan angles for cards; front/back/detail for fashion items. FLUF sends gallery images up to Whatnot’s limit. |
| Price | Buy it now price | ✅ Automatic | Transferred directly as a fixed-price listing. Whatnot buyers can still make offers on fixed-price items. |
| Category | Category | ⚡ Smart mapped | Mapped to the appropriate Whatnot category — Sports Cards, Trading Card Games, Fashion, etc. |
| Condition | Condition | ✅ Automatic | Condition is especially important for graded cards — include the grading service and grade in the title or description. |
Inventory Sync Between Wix and Whatnot
| Event | What FLUF does |
|---|---|
| Item sells on Wix | Whatnot listing automatically delisted |
| Item sells on Whatnot (fixed price) | Wix stock zeroed; delisted from other connected channels |
| Price edited on Wix source | Updated price syncs to Whatnot fixed-price listing |
| Item sells in a Whatnot live show | ⚠️ Live show auction sales are handled within Whatnot’s live infrastructure — FLUF monitors sold status and records the order, but this happens separately from the fixed-price listing sync |
Overselling protection
For unique collectibles or limited inventory crosslisted to both Wix and Whatnot, FLUF’s sold sync removes the window for a double-sale. The moment a fixed-price item sells on Whatnot, Wix stock is zeroed and the listing pulled from other channels. For cards and collectibles where one-of-one graded pieces are common, this protection is essential — a double-sold PSA 10 Charizard is an expensive and reputation-damaging problem to resolve.
Automation Features for Wix and Whatnot Sellers
| Feature | Wix | Whatnot |

| Inventory sync | ✅ Yes | ✅ Yes |
| Order sync | ✅ Yes | ✅ Yes |

How Much Does It Cost to Crosslist from Wix to Whatnot?

There are no listing fees on Whatnot and no monthly seller subscription fees. Whatnot generates revenue from commission on completed sales only, which aligns its incentives directly with sellers — the platform earns nothing until you make a sale, meaning Whatnot has structural reasons to invest in buyer acquisition and show promotion that benefit every seller on the platform. For comparison: Whatnot’s 8% US commission is lower than eBay’s typical 12.35% final value fee in most fashion and collectibles categories, making it cost-competitive as a second channel for Wix store owners who are already absorbing eBay fees and looking for alternatives with better category-specific buyer intent.
On Whatnot’s side, US/CA/AU sellers pay 8% commission on items up to $1,500 (0% on the portion above $1,500) plus 2.9% + $0.30 payment processing per transaction. UK and EU sellers pay 6.67% commission + local VAT plus 2.42% + £/€0.25 processing source. Electronics sellers benefit from a reduced 5% commission rate. There are no listing fees and no monthly seller subscription on Whatnot. Whatnot’s Shopify Sales Channel integration (launched March 2026) also enables bidirectional product and inventory sync for sellers using both Shopify and Whatnot source.
