The problem QST removes
Your product is already written. Why rebuild it for every marketplace?
QST starts with the product data you already have in Shopify and turns repetitive listing preparation into a clear, reviewable workflow.
See what actually needs attention
Use clear readiness checks to focus on the products that need a decision, rather than reviewing every field blindly.

Built for the details
Small safeguards that remove expensive mistakes
QST is designed around the parts of marketplace listing work that are easy to repeat, miss or misunderstand.
eBay title limit handled
QST Desktop shortens an over-length title at a word boundary, keeping it within eBay’s 80-character limit without chopping a word in half.
Readiness that explains itself
Pass, review and needs-work checks tell you why an item has been flagged and what action is warranted.
One-click, seller-controlled publishing
Select one product or several, click Publish to eBay once, and QST Desktop validates and processes the selection using your saved settings. Nothing starts until you choose it.
Reusable listing packs
Create clean text, CSV and ready-to-upload image packs for manual marketplace workflows.
Local image tools
Save images, remove backgrounds, compare cutouts, refine results and keep the work on your own computer.
Faster catalogue navigation
Search, filter, exclude, select in bulk and keep local changes organised across a larger catalogue.
Try your own numbers
How much repeated listing time could you reclaim?
Use your real weekly volume and timings. This is an illustrative estimate, not a promise, and you can change every input.
Time saved weekly1.2 h
Time saved yearly61 h

The estimate compares the two timings you enter and multiplies the difference by 52 weeks. Your actual result depends on your products and workflow.
Control stays with you
Your Shopify catalogue remains the source, not the target.
QST’s Shopify access is read-only by design. It can prepare data for other workflows, but it cannot silently rewrite your products, inventory, prices or tags.
No Shopify overwritesYour original product records remain unchanged.
No automatic eBay postingYou review and choose when to publish.

Why I built QST
Mark Sowden, founder of Q‑MER.CH and creator of QSTI built QST out of frustration. The other platforms I found were expensive, and syncing in the wrong direction risked changing my Shopify inventory. I knew because it had happened before.
At first, it was just for me. I struggle to repeat work I have already completed, so I would end up not listing products in places I should. I was saving my sanity, but losing sales.
The idea was simple: build a tool that could read information from Shopify without writing anything back, let me make changes on the fly inside the tool, and create the resources and structure needed to list elsewhere quickly. That was the start of what became the Q‑MER.CH Sync Tool, or QST.
Questions before you start
QST, explained plainly
Can I try QST before paying?
Yes. QST includes a fully functional seven-day free trial, so you can use every feature and try the complete workflow first. After the trial, choose $9.99 monthly or $99 yearly. The subscription and billing are handled through Shopify.
How much does QST cost?
QST costs $9.99 per month or $99 per year through Shopify. Paying yearly saves $20.88 compared with twelve monthly payments.
Do I need QST Desktop to use the Shopify app?
No. QST Listing Workspace can review products and create downloadable packs by itself. Add QST Desktop when you want direct eBay publishing, local image tools and the wider desktop workflow.
Can QST change my Shopify products?
No. QST uses read-only Shopify access. It can read the product information needed for listing preparation, but it cannot overwrite your Shopify catalogue.
Does connecting eBay publish my products automatically?
No. Connecting eBay prepares QST Desktop to use your seller account. You still review a listing and choose the publish action before it is sent.
Can I publish several selected products with one click?
Yes. Tick one product or multiple products in QST Desktop, then click Publish to eBay once. QST processes the selection as a batch, shows progress for each item and reports any listing that still needs attention.
What must be configured before direct eBay publishing?
You need to connect an eBay seller account and choose the required business policies, dispatch location and category settings in QST Desktop. The setup screens guide you through those choices.
What happens to eBay titles over 80 characters?
QST Desktop smartly shortens an over-length title at a word boundary so it stays within eBay’s 80-character limit without cutting a word in half. You can review the result before publishing.
Can QST help with Etsy, Vinted and other marketplaces?
Yes. QST can create marketplace listing packs containing reusable text and images for manual workflows. Direct publishing is currently the eBay capability in QST Desktop.
Where can I try QST-style listing helpers first?
Use the free eBay Title Builder and Marketplace Description Cleaner in your browser. No account is required for those tools.
