Cross-border e-commerce breaks generic apps fast. You need country-specific pricing rules, multi-currency duties calculations, market-specific fulfillment routing, and integrations with European logistics and ERP systems that the App Store simply does not cover. So you stitch together workarounds, pay for overlapping subscriptions, and still do the hard parts by hand.
- An app built for your exact cross-border workflow, with no workarounds
- Clean integration with Shopify Markets, your logistics network, and your ERP
- Faster, more reliable international operations without manual handling
- A maintainable app we support and grow with you as you enter new markets
What's included
A clear path from start to finish
Scope and design
We map the cross-border problem, the Shopify resources involved, and the data flow across your target markets, then agree on a clear spec, timeline, and fixed price.
Build and integrate
We build the app against the Shopify API, connect your international logistics and ERP integrations, and test it on a real multi-market store while you track progress along the way.
Launch and support
We deploy the app, handle the App Store submission where needed, then monitor, maintain, and develop it further as you expand into new markets.
Is this the right fit for you?
Have a cross-border Shopify problem that no app solves? Let's build the one that does.
Frequently asked questions
Can you build apps that handle Shopify Markets and multi-currency logic?
Yes. We build apps and extensions that work natively with Shopify Markets, handling country-specific pricing, duties, tax rules, and fulfillment routing across all your target markets.
How much does a custom Shopify app cost?
It depends heavily on scope. A simple admin extension for a single market is a very different project from a multi-market ERP integration. Most projects fall somewhere between 10 000 and 50 000+ zł, and we give you a fixed price after a short discovery call.
Can you integrate Shopify with European logistics providers and ERPs?
Yes. We connect Shopify with European 3PLs, ERPs, customs brokers, and fulfillment systems so data flows automatically across all your markets instead of being re-entered by hand.
Will you maintain the app as Shopify evolves?
Yes. The Shopify platform evolves constantly, and international compliance requirements change too. We offer ongoing maintenance, monitoring, and updates to keep your app running smoothly and compliant in every market.
