eBay listing checks catch margin, shipping, and compliance issues before uploadBuilt for eBay.com & eBay.co.uk sellers
Stop losing money to fees you didn't see coming.

How it works
From stock to sold, in four steps
No steep learning curve. The same simple loop runs for one item or a thousand.
- 1
Add your stock
Photograph an item or import a supplier list. Sellers Delight drafts the listing and fills in the eBay item specifics for you — no blank forms to fight.
- 2
Check the numbers
Before anything goes live, you see the real eBay fees and your true net margin. Nothing publishes that quietly loses money.
- 3
Preflight, then publish
A quick pre-publish check catches shipping, compliance, and data errors that eBay would otherwise bounce. Fix once, publish clean.
- 4
Track orders & restock
Orders, tracking, and stock levels stay in sync, so you know what to reorder before your fast movers run dry.
Getting started
Set up your account in minutes
Three steps from signing up to your first live listing. No card required to start.
Create your account
Sign up with your email — no card needed. Your 30-day trial with core workflow access starts straight away.
Connect your eBay account
One secure click sends you to eBay's own sign-in to authorise access. We never see your eBay password, and you can disconnect any time.
List your first item
Add a product, let AI Assist draft it, check the margin, and publish. Most sellers have a clean listing live in minutes.
Connections & billing
How the connections work — and what you actually pay
Sellers Delight talks to eBay and to AI on your behalf. Here's exactly how that is set up and billed, so there are no surprises.
Connecting eBay is free
We use eBay's official API and secure sign-in (OAuth). eBay doesn't charge you to connect, and we don't add a fee for it. Your eBay selling fees stay exactly as eBay sets them — we simply show them to you before you list.
AI Assist runs on included credits
The AI that drafts listings is powered by Claude. Each draft or enrichment uses one AI Assist credit, and a monthly allowance is already included in your plan — 20 on trial, 75 on Starter, 150 on Premium. No separate API key to manage.
No surprise bills
You pay one predictable subscription. If you use up your monthly AI Assist credits, features simply pause until they reset — nothing charges you extra without you choosing to upgrade. What you see on the pricing page is what you pay.

The person behind it
Built by an eBay seller who got tired of the guesswork
I'm Mark Horne, the founder and engineer behind Sellers Delight. I'm an eBay seller myself, and I got tired of two things: the hours it takes to list a pile of stock, and finding out after the sale that eBay's fees had quietly eaten the margin.
So I taught myself to build software and made the tool I actually wanted — one that drafts your listing from a photo, fills in the eBay item specifics, and shows the real fees and net margin before you publish. It's live, in production, and I use it on my own stock every week. Built on Next.js, the eBay API, Stripe, and Claude.
I'm the engineer, focused on making the product excellent — you can reach me any time at markhorne@sellersdelight.com.
What can improve
Realistic outcomes in daily operations
- Start the morning knowing exactly which listings need fixing before peak traffic.
- Spot drifting margins before listings go live — not after they've already sold at a loss.
- Know your true net margin on every SKU, with eBay fees already calculated in.
- Cut time-to-publish on new supplier stock — preflight catches the errors before eBay does.
Results vary by catalogue size, process quality, and sourcing consistency. The goal is steady, compounding operational improvement.
