Built for online sellers ready to go global

Whether you run a Shopify boutique or a WooCommerce warehouse, Mastersel connects your store to international buyers without changing how you work.

Shopify and WooCommerce store owners

You already have a working online store and domestic sales. Mastersel lets you expand to 30+ countries using a native plugin that installs in minutes, with no migration or replatforming. Your inventory stays in sync automatically, so you manage one catalog while selling everywhere.

Small brands scaling beyond their home market

If you have proven product-market fit domestically and want to test international demand, Mastersel removes the barriers. There are no upfront costs, no marketplace registration headaches, and automatic localization handles translations and local formatting. You can validate new markets with zero financial risk before committing resources.

Multi-channel sellers tired of manual work

If you are already listing on multiple marketplaces but spending hours on CSV exports, manual stock updates, and separate logins, Mastersel consolidates everything. One connection syncs products, orders, and inventory across all channels. Pair it with free logistics and you eliminate operational overhead entirely.

Connect your online store globally

Install a plugin, connect your store, and start selling internationally. Native integrations with the platforms you already use.

Zero-code plugins

Native plugins for WordPress, Shopify, PrestaShop, OpenCart, and Verskis. Install, authenticate, and your store is connected in under two minutes. Each plugin is built specifically for the platform's architecture, ensuring stable performance and compatibility with your existing theme, apps, and extensions. No developer involvement or technical knowledge is required at any step.

Storefront integration

Your existing online store becomes a gateway to 30+ international marketplaces. No separate storefronts to manage, no theme changes. Your domestic checkout, payment processing, and customer accounts continue working exactly as before while new international orders flow into a unified dashboard alongside your existing business.

Instant sync

Orders, inventory, and product updates flow automatically between your store and every connected marketplace in real time. When you update a price, add new images, or adjust stock in your store admin, those changes propagate to all channels within seconds. This eliminates the risk of selling out-of-stock items or displaying outdated product information on any marketplace.

Custom XML import

Running a custom stack? Import your products via XML feed. Full documentation and support included for any platform. Whether you built your store from scratch, use a niche CMS, or manage inventory through an ERP system, the XML integration accepts standard product feeds and maps them to marketplace-ready listings automatically.

E-commerce integration FAQ

Which e-commerce platforms have Mastersel plugins?

Mastersel offers plugins for Shopify, WordPress (WooCommerce), PrestaShop, OpenCart, and Verskis. Each plugin installs in under two minutes with no coding required.

Can I connect a custom-built store?

Yes. If your store runs on a custom platform, you can import your product catalog via a standard XML feed. Full documentation and support are included.

Do I need to rebuild my online store?

No. Mastersel connects to your existing store. You keep your current platform, theme, and checkout. We simply extend your reach to 30+ international marketplaces.

How does order routing work?

When a customer buys your product on any marketplace, the order flows back to your Mastersel dashboard. You fulfill it from your location and we handle shipping labels, tracking, and customs.

Is there a cost to connect my store?

Connecting your store is completely free. There are no setup fees, no monthly subscriptions, and no commissions. Shipping is completely free — covered by Mastersel's retail markup. Start selling online internationally today.

How long does it take to start selling on international marketplaces after connecting my store?

Most sellers go live on their first international marketplace within 24 hours of installing the plugin. After the two-minute plugin installation, your product catalog syncs automatically — including titles, descriptions, images, and variants. Mastersel then handles product localization, translation, and listing optimization for each target marketplace. The exact timeline depends on catalog size, but even stores with thousands of products typically complete their initial sync within a few hours.

What happens to my existing orders and customers if I connect Mastersel to my Shopify or WooCommerce store?

Your existing store operations remain completely unaffected. Mastersel runs alongside your current setup without modifying your theme, checkout flow, or existing customer data. Domestic orders placed through your own store continue to process exactly as before. The plugin only adds new international marketplace orders to your workflow — they appear in your Mastersel dashboard and can be managed from a single unified interface. There is zero disruption to your current business while you expand internationally.

Why connecting your existing store to international marketplaces matters

Most e-commerce sellers start with a single online store serving their domestic market. The store works well — products are listed, orders flow in, fulfillment runs smoothly. But when these sellers consider international expansion, they face a decision matrix that slows most of them down: register as a seller on each foreign marketplace individually, navigate platform-specific APIs, build custom integrations, handle multi-language listing requirements, and manage separate order streams from every channel. The result is that many profitable domestic sellers never expand internationally, leaving revenue on the table in 30+ European markets where demand already exists for their products.

Mastersel was built specifically to solve this problem. Instead of asking sellers to adapt their operations to each marketplace, the platform adapts each marketplace to the seller's existing workflow. You install a single plugin on your current store — whether it runs on Shopify, WooCommerce, PrestaShop, or OpenCart — and your entire product catalog becomes available across international sales channels within hours. Your existing store remains your primary interface for managing products. Mastersel simply extends its reach across borders.

Plugin architecture designed for zero disruption

Each Mastersel plugin is built natively for its target platform. The WordPress plugin uses WooCommerce hooks and actions natively, the Shopify app follows Shopify's embedded app framework, and the PrestaShop module integrates through the platform's standard module architecture. This native approach means the plugin doesn't conflict with your existing theme, payment gateways, or third-party apps. Your domestic checkout continues working identically. Customers shopping on your store see no difference. The plugin works silently in the background, syncing your catalog to international channels and routing incoming orders back to your unified dashboard.

From local store to international seller in one step

The traditional path to selling internationally involves registering as a seller on each target marketplace (Amazon, eBay, local platforms), learning each platform's product data requirements, translating listings manually, setting up per-country shipping accounts, and navigating cross-border tax compliance. Each step takes days or weeks and requires specialized knowledge. With Mastersel, the entire process is compressed into a single step: install the plugin. The platform handles translations and localization, currency conversion, customs compliance, and logistics setup automatically. You go from "local store" to "international seller" in the time it takes to install an app and authenticate your store.

Maintaining control while scaling reach

A common concern among online sellers considering international expansion is loss of control. When your products appear on external marketplaces, how do you ensure brand consistency? How do you prevent pricing errors across currencies? How do you keep inventory accurate across all channels? Mastersel addresses each concern through automation: brand elements are preserved in translated listings, pricing updates propagate instantly when you change prices in your store admin, and inventory syncs in real time to prevent overselling. You maintain full control over your catalog while the platform handles the international complexity behind the scenes.
