Bi-directional stock synchronization that updates every connected channel within seconds. When a sale happens on Allegro, your eBay, Amazon, and Kaufland listings reflect the change before another buyer can checkout. No more overselling, no more manual stock updates.
Selling on multiple marketplaces multiplies your revenue potential, but it also multiplies the risk of overselling. A customer buys your last unit on Allegro while another buyer is checking out on Amazon. Without real-time synchronization, both orders go through, and you are left with a cancellation, a negative review, and a potential marketplace penalty.
Manual stock management does not scale. Updating inventory spreadsheets across 5, 8, or 12 marketplaces is a full-time job that still leaves gaps. Marketplace algorithms penalize sellers who cancel orders due to stock issues, pushing your listings lower in search results and reducing your visibility to buyers. The cost of one oversold order goes far beyond the refund itself.
Marqetir eliminates this problem entirely. Our bi-directional inventory sync connects your source store (Shopify or WooCommerce) to every marketplace you sell on and keeps stock levels accurate across all channels in under one minute. Combined with configurable safety buffers and multi-warehouse allocation, you get complete control over your inventory without the manual overhead.
Everything you need to keep inventory accurate across every sales channel, from safety buffers to multi-warehouse allocation.
Stock levels propagate to every connected marketplace within seconds of a sale, cancellation, or restock. High-velocity sellers can rely on near-instant updates to keep listings accurate even during flash sales and peak shopping events.
Set per-marketplace or per-product buffer quantities so you never list your last unit on a channel with slow fulfillment. Buffers are fully configurable and can be adjusted by season, marketplace velocity, or supplier lead time.
Allocate specific warehouse inventory to specific marketplaces. Sell from your EU warehouse on Allegro and Kaufland while reserving UK stock for eBay and Amazon UK, all managed from a single dashboard with per-location visibility.
Orders from every connected marketplace flow into your source store (Shopify or WooCommerce) automatically. Stock is deducted at the source the moment an order is confirmed, eliminating manual entry and reducing fulfillment errors.
Bi-directional sync means a sale on Allegro instantly reduces available stock on Amazon, eBay, Kaufland, and every other channel. Combined with safety buffers and sub-minute propagation, overselling becomes a problem of the past.
Three steps, fully automatic. From the moment a sale happens to every channel being updated, the entire process takes under a minute.
A customer places an order on any connected marketplace or your own Shopify/WooCommerce store.
Marqetir detects the order within seconds and deducts the sold quantity from your central inventory pool.
Updated stock levels push to every connected marketplace simultaneously, preventing any other channel from selling unavailable inventory.
Whether you sell 50 SKUs or 50,000, inventory sync adapts to your business model.
Running a promotion on Allegro while selling normally on Amazon? Inventory sync ensures that a surge in orders on one channel does not create ghost stock on another. Safety buffers give you an extra layer of protection during high-volume periods.
Selling from a Polish warehouse on Allegro and a German warehouse on Kaufland? Multi-warehouse support lets you assign location-specific stock to the right marketplace, preventing orders you cannot fulfill from the correct facility.
Products that sell dozens of units per hour need instant sync. Marqetir processes stock changes in real time, so a product selling fast on eBay does not show outdated availability on bol.com or Cdiscount.
Adjust safety buffers and marketplace allocations seasonally. Reserve more stock for high-performing channels during Q4, then redistribute in slower months. All changes propagate across channels immediately.
Connect your store and marketplaces in minutes. Real-time inventory sync starts working from your first order.
