Every marketplace wants something different
The same product needs different categories, required attributes, title rules and image specs on Amazon, Rakuten and Allegro. Fitting one channel gets you rejected by the next.
Enter a product once,
list it on every marketplace
One Product Master → Multiple Marketplace Listings
Seoulique is not an agency that sells on your behalf. It is a Commerce OS you operate yourself. Enter a product once, and AI analyses it, builds the multilingual content, and — once you approve — converts it into each marketplace's format and creates the listing through their API.

How it works
One product record, many marketplace listings
Product data is never rebuilt per channel. Everything starts from a single Product Master and is converted into the format each marketplace demands.

You enter the product once. Seoulique publishes it to each marketplace.

The problem
What blocks cross-border sales is rarely the product
The product is usually competitive already. The wall is always what comes next.
Localisation, not translation
Machine-translated detail pages do not sell. Worse, a single non-compliant claim can take an entire listing down.
Costs you cannot see
Selling price minus purchase price is not profit. Only after platform fees, duties, freight, FX, advertising and return rates do you see real contribution margin.
Channels that never talk to each other
Changing a price means logging into seven sites. So does stock. So do orders. Every channel you add multiplies manual work, not capability.
Direct listing
Not "integration" — the listing actually gets created
The goal is not to display marketplace data. It is to call each marketplace's API and create a real product listing there.
01
Enter the product once
Product data and supply terms go into Seoulique once. SKU, dimensions and barcode are generated, and the cost structure is set up automatically.
02
Choose the marketplaces
Tick where this product should go. Publish one product to many marketplaces, or to a specific few — the choice is per product.
03
Automatic per-marketplace mapping
Required attributes, categories, title rules, descriptions, image specs, variations, pricing, shipping and regulatory fields are converted into each marketplace's format. The Product Master itself is never modified.
04
You approve the conversion
Per-marketplace conversion status is shown before anything is sent. Problems surface before listing, not after a rejection.
05
Published through each marketplace API
Press [Publish] and each marketplace's API is called to create the actual listing. Nobody re-enters the same product on seven websites.
06
Results and retries
Success and failure are reported per marketplace. Only the failed ones are fixed and retried; listings that already succeeded are never created twice.

Amazon JP
ERROR
Missing Attribute: battery_type
Fix the Product Master → re-validate → resend to that marketplace only. That is the loop.
Partial success is supported
Two failures out of eight do not roll back the rest. Successful listings stay up; only the marketplaces that errored are reprocessed.

Here is exactly where we are
Seoulique Commerce OS has completed its design and is in active development. None of the seven marketplaces above can create listings through their API yet. We would rather tell you that now than have you find out after we start working together.
Ask us about the development timeline
After listing
Publishing is the beginning, not the end
A listing only becomes a business when price, stock, orders and settlement stay connected to every channel afterwards.
Change a price once
Change the price in Seoulique and it propagates through each marketplace API. No logging into seven sites. Per-marketplace target prices account for FX and platform fees.
See one inventory
Stock scattered across countries appears on one screen. Changes sync to each marketplace, and the system flags stockout risk and reorder points before they bite.
Orders land in one place
Orders from every marketplace are collected into the Seoulique Order Core. Shipping and returns run through the same flow.
Profit, per marketplace
Measured as contribution margin, not revenue. You can see which country, which marketplace and which SKU actually makes money — and reorder on that basis.
Your accounts
Your seller accounts, under your own authorisation
Seoulique does not own or operate marketplace accounts on your behalf. You connect the API permissions of the seller accounts you already hold, and Seoulique creates and updates listings strictly within that scope.
The accounts stay yours
Seller accounts, storefronts and payouts all remain in your name. You can disconnect at any time.
Credentials are never displayed
API keys and secrets live in a dedicated secret manager, never in files or spreadsheets. The interface shows connection status only.
Every change is logged
Price changes, purchase-order approvals, data edits and API calls are all recorded. Who changed what, and when, stays traceable.

Why us
Decisions made on numbers, not instinct
What to sell, what to charge, when to reorder — all three are designed around a quantified basis.
A 100-point product score
Ten weighted criteria produce a verdict: STRATEGIC, APPROVED, TEST, HOLD or REJECT. The standard stays the same no matter who runs the review.
A twelve-line cost engine
Purchase price, domestic China freight, international freight, duties, customs, local delivery, packaging, platform fees, fulfilment, advertising, expected returns and expected defects all feed contribution margin.
Compliance checked before listing
Certification, trademark and patent risk are screened at registration — not after a listing has already been pulled.
A person signs off
AI assists the judgement; it does not make it. Large purchase orders, major price moves, supplier changes and legal saleability are decided by people.

What AI is never allowed to decide alone
Certification, legal saleability, final judgement on patent infringement, large purchase orders, high-value refunds, major price changes and supplier changes. On these seven, a person is always accountable.
Early partners
We are looking for people to start with now
Joining during development means your real products and your real marketplace requirements shape the product. That is different from adopting something already finished.
Manufacturers and brands
You have a strong product but no overseas channel or language capability
- Own production or own brand
- Little or no export experience so far
- No dedicated team for certification and specs
Domestic sellers
You sell well at home but cross-border expansion has stalled
- Proven sales on Coupang, Naver or similar
- You already hold overseas marketplace accounts, or plan to open them
- Multilingual detail pages are the bottleneck
Sourcing and supply partners
You hold supply chains in China or Southeast Asia
- A vetted supplier network including 1688
- Reliable MOQ and lead times
- Cost leverage built on long-standing relationships
FAQ
Questions we usually get
Can we start listing products today?
Not yet. Seoulique Commerce OS has finished its design and is in active development; no marketplace can create listings through its API at this point.
The status shown in the marketplace section is the real development state, and it changes when listing genuinely works. Early partners get connected in the order each channel becomes ready.
Does Seoulique sell our products for us?
No. You are the seller. Seoulique is software you operate.
Your marketplace seller accounts stay in your name, and listing, pricing and stock operations happen only within the API permissions you grant. Payouts go to your accounts.
What is the difference between "integration" and "direct listing"?
Most tools mean reading marketplace data or pulling in orders. The product itself still has to be typed into each site by a person.
What Seoulique is built for is completing the per-marketplace mapping and then calling each API to create the real listing. Price, stock and orders continue along the same path afterwards.
What happens if only some marketplaces fail?
The whole batch is not rolled back. Listings that succeeded stay live, and only the marketplaces that errored are reprocessed.
Errors arrive with their cause. If Amazon JP is missing the battery_type attribute, you fix the Product Master, re-validate, and resend to that marketplace alone. Nothing already published gets duplicated.
Is the translation machine-generated?
No. Everything starts from a Korean master and is designed to pass four stages: localisation, terminology review, regulatory-claim review and final approval.
The regulatory stage matters most. Prohibited efficacy and safety claims differ by country, and missing one can take a listing down or put the account at risk.
How are our API credentials protected?
API keys and secrets are held in a dedicated secret manager, never in files or spreadsheets. The interface shows connection status only; secret values are never displayed.
Price changes, purchase-order approvals, data edits and API calls are all logged. You can disconnect at any time.
