Catalogue, stock and pricing drift between your store and each marketplace
What's in stock on your site and what a marketplace shows can quietly stop matching.
Marketplace channel integration
One catalogue feeding Amazon, Allegro and every other marketplace channel you sell on — not six manual exports.
For sellers whose catalogue, stock and pricing drift between their own store and Amazon EU, OTTO, Allegro, Cdiscount, Zalando or Kaufland once an off-the-shelf connector stops scaling.
SIGNS THE CONNECTOR HAS OUTGROWN THE TOOL
The connector outgrew the tool running it — four ways that shows.
Every marketplace has its own taxonomy, feed format and approval rules
The same product needs reformatting five different ways before it can even go live.
Off-the-shelf connector tools can't handle your volume or business rules
The tool that worked at a smaller catalogue size starts timing out or silently dropping updates.
Product-safety data and repricing logic need maintaining per channel
Keeping GPSR-compliant data and competitive pricing current across six channels by hand doesn't scale.
OUR APPROACH
A SaaS connector, a custom integration or a hybrid — the choice follows your volume, not your preference.
Tools like Lengow or ChannelEngine are often still the right fit. The real question is where your volume or business rules actually outgrow what they can do.
SaaS connector
Use an existing tool like Lengow or ChannelEngine when standard catalogue, stock and order sync covers your case.
The lowest-effort option, and often still correct — not every seller needs custom integration.Custom connector
Build direct, contract-tested integrations when volume, business rules or channel-specific logic outgrow a generic tool.
More control, but your team now owns the connectors' reliability, not a vendor.Hybrid
Keep a SaaS tool for most channels while building a custom path for the one or two with real volume or complexity.
Needs a clear source of truth so the two approaches don't quietly disagree with each other.WHAT WE CAN OWN
One catalogue, synced stock, and orders in one place.
One catalogue, many destinations
Your product data flows out to every connected marketplace in the format each one actually requires, instead of being re-entered or re-exported by hand.
Category mapping and marketplace-specific listing rules still need your product team's judgment on edge cases.Stock and pricing that stay in sync
Inventory and price changes propagate to every channel in near real time, so what customers see matches what you can actually fulfil.
Setting the actual repricing strategy and margin rules is a business decision we implement, not one we make for you.Orders and returns landing in one place
Every marketplace order and return routes into your existing system of record, so support doesn't have to check six different seller dashboards.
Each marketplace's own payout and dispute process still runs on their platform, not ours.HOW WE WORK
Map → Design → Connect → Operate.
Map
In
Your current channels, feed formats, taxonomies and known reconciliation gaps.
We do
We inventory what's actually syncing today and where it quietly isn't.
Out
A clear picture of channel health before anything gets built.
Design
In
The map and your target channel list.
We do
We define the source of truth, transformation rules and failure handling per channel.
Out
A sync architecture that names what happens when something fails.
Connect
In
The design and API access for each marketplace.
We do
We build or extend connectors for catalogue, inventory, pricing and orders.
Out
Working sync for the first group of channels.
Operate
In
Live channels and real order volume.
We do
We monitor sync health, reconcile discrepancies and add channels incrementally.
Out
A channel setup that scales without drift creeping back in.
FREQUENTLY ASKED
Questions before you connect another marketplace.
Which marketplaces can you integrate?
Amazon EU, OTTO, Allegro, Cdiscount, Zalando, Kaufland and Bol.com are common; other channels can be added based on API availability.
Can this replace tools like Lengow or ChannelEngine?
Sometimes a SaaS connector is still the right fit — we help you decide, and build custom integration only where volume or rules outgrow it.
How do you handle GPSR product-safety requirements?
Product-safety attributes are modelled as part of the catalogue sync so every channel receives the data it requires.
What happens when a marketplace changes its API?
Connectors are built with contract tests and monitoring so a breaking change is caught and fixed before it silently corrupts data.
