How It Works
eBay-only to five channels in under 5 minutes.
1. Connect
One-click login for eBay, Amazon, Shopify, Walmart, and Etsy. No API keys. No developer. No spreadsheets.
2. Import
We pull your full eBay catalog — images, descriptions, variants, pricing — in seconds. Nothing to map by hand.
3. Cross-list
Push to every other channel with one click. We rewrite each listing for the platform that's reading it — Amazon bullets, Etsy tags, Shopify SEO. Not copy-paste. Not generic.

3Dsellers handles the complexity of multichannel selling so you don't have to.
Inventory Sync
Real-time stock sync across all platforms in under 30 seconds. Sell on Amazon, your eBay listing updates instantly.
AI Optimization
AI rewrites your listings per platform — Amazon bullet points, Etsy tags, Shopify SEO. Not a generic copy-paste.
Unified Orders
Every order from every platform in one inbox. No more switching between 5 browser tabs.
Oversell Protection

Real outcomes sellers see in their first 90 days. Same catalog, same effort — more channels, more revenue.
+47% revenue in 90 days
Average seller adds nearly half their revenue in three months — without launching a single new product. Same catalog, more buyers.
+10 hours back every week
Stop copy-pasting between Amazon, eBay, and Shopify tabs. Listings push to every platform in one click. Sync runs in the background.
Algorithm-proof revenue
One platform tanks? You have four more. Spread your business across 5 marketplaces and stop losing sleep over the next eBay update.

Per-Platform Listing Rewrites (Not Copy-Paste)
Amazon ranks on bullets. Etsy ranks on tags. Shopify ranks on meta. We rewrite each listing to match — automatically. You're not pasting the same eBay title into four boxes and hoping.
One Inbox for Orders, Messages, and Feedback
Every order, buyer message, and review from all five channels lands in one screen. Close 14 browser tabs. Run the whole operation from one place.

Great experience: reliable platform...
We’ve had a great experience with 3Dsellers. It’s been a dependable platform for improving our eBay workflow—especially listing and order management—and it saves us a lot of time. Their customer support is professional and genuinely helpful. Highly recommended for serious eBay sellers.

3Dsellers Checks All the Important Boxes
My overall experience has been exceptional. On top of the quality software product, the customer service goes above and beyond. On more than one occasion, I've gotten responses and fixes to glitches even when I'm contacting the company outside normal business hours. As I find little bugs or opportunities to correct something in the software, the team responds with a fix usually within hours. I could not be more pleased with the support this company gives to their excellent product.

Frequently Asked Questions
Everything you need to know about multichannel selling with 3Dsellers.
Which platforms do you support?
Currently: eBay, Amazon, Shopify, Walmart, and Etsy. More marketplaces coming soon.
How fast does inventory sync?
Under 30 seconds across all connected platforms. We use webhooks, not polling — so you'll never oversell.
What happens if I oversell anyway?
We auto-pause the listing on platforms where stock hits zero and send you an alert. No more angry buyer messages.
Can I import my existing eBay catalog?
Yes — automatically, on day one. We pull every active listing including variants, images, and pricing. Most sellers are fully imported within 60 seconds.
Do I need technical skills?
No. If you can use eBay, you can use 3Dsellers. Most sellers are live on Amazon and Shopify within an hour of signup.
What if I cancel?
Cancel anytime in one click. Your store keeps running normally — we don't lock you in.
Where does the 47% revenue lift number come from?
It's the median revenue increase reported by 3Dsellers customers in their first 90 days after going live on 3+ platforms. Some sellers see more, some see less — your results depend on your catalog, niche, and how aggressively you cross-list.
Will Amazon, Walmart, or Etsy ban me for cross-listing from eBay?
No. Selling the same products across multiple marketplaces is normal and allowed on every platform we support. We help you stay compliant by rewriting listings per platform's rules — Amazon's bullet points, Etsy's tags, Walmart's category specs — so each listing looks native, not copy-pasted.
How much does it actually cost?
Plans start at $19/month with a 7-day free trial. No credit card required to start. Most multichannel sellers earn back their first month's cost within their first weeks of cross-listing.
How fast can I really get live on Amazon and Shopify?
Day one. Connect your eBay account, we import your catalog , then you push it to Amazon, Shopify, Walmart, and Etsy in one click. Most sellers are live on at least 3 platforms within an hour of signup.
