What is the minimum budget for a custom web shop?

A headless e-commerce store built on Next.js 16 (for example with Medusa.js as the commerce backend) starts at approximately €5,000 for a standard setup including product catalogue, cart, payment integration, and admin panel. This covers design, development, and deployment on serverless infrastructure that handles traffic spikes without downtime. More complex builds with multi-currency support, ERP integration, or product configurators cost between €8,000 and €18,000. Every project receives a fixed quote before work begins.

Which payment gateways do you support?

Stripe is our default for EU and international stores, together with PayPal, Apple Pay and Google Pay. For clients in Croatia, CorvusPay, Keks Pay, T-Pay and WSPay are possible integrations on request. Every integration includes PCI-compliant checkout, webhook-based order confirmation, and automated invoice generation. Multi-currency support is built in as standard, so your customers pay in their preferred currency with real-time exchange rate handling.

Can the shop integrate with our existing ERP system?

Absolutely. We can connect the store to ERP systems such as SAP Business One, Odoo or Microsoft Dynamics, or to a custom ERP, via REST API and n8n workflow automation, scoped per project. This enables real-time inventory synchronisation, automated order routing, and bidirectional stock updates that eliminate manual data entry. The integration runs continuously, so product availability on your webshop always matches your warehouse reality, so overselling stops being a regular problem.

Can we manage the shop ourselves after launch?

Yes, you receive an admin panel where your team can independently manage the entire catalogue: add products with variants and images, process orders, configure discount codes, and adjust pricing without writing a single line of code. We also provide a structured onboarding session and video documentation, so your team is confident from day one. The admin interface is responsive and accessible from any device, enabling order management even while away from the office.

Will a new online store increase sales on its own?

Not by itself. A new store removes obstacles: faster loading, a clearer checkout, search that actually finds the product, and a mobile experience that does not break down. If visitors already reach you, that shows up in the share of them who complete a purchase. If there are no visitors, the store has nothing to convert and the problem sits in your channels, not in the shop. That is worth saying before the project, not after.

Why not just use Shopify?

For many stores Shopify is the sensible choice, and we will tell you so. If you have a standard catalogue, standard shipping and a standard checkout, a hosted platform gets you to market faster and cheaper up front. Custom becomes worth it when the platform starts getting in the way: non-standard pricing or configurator logic, a deep link into an ERP or warehouse, local invoicing requirements, or transaction fees that become a serious cost at your volume. We make that call from your numbers, not from what we would rather build.

Will a redesign fix abandoned carts?

Partly. Some abandonment comes from things a store controls: forced registration, shipping costs that only appear at the end, a slow checkout, too few payment methods. The rest comes from price, availability, or a shopper who was only comparing. We measure where people actually drop out first, then fix that step. Redesigning the whole store without that data is guesswork.

How are invoicing and tax compliance handled?

Through an integration with the accounting or ERP system you already run, so invoices are created in one place. The store sends order data to the system that already issues your invoices instead of keeping a parallel record that drifts out of sync over time. Before we start we confirm which system you use and whether it exposes an API, because that determines how involved the integration is. If it has no API there are workarounds, but that needs to be known up front.

Can we migrate existing orders, customers and search rankings from the old store?

Yes, and it is planned before the migration rather than after. Products, categories, customers and order history are moved by script from the old store's database. Search positions are protected by redirects: every old product and category URL gets a 301 to its new equivalent. Migrations that skip that step routinely lose organic traffic in the first weeks, and it is hard to win back.

Who manages stock and pricing after launch?

You do, from the system you already use for it. If stock lives in an ERP or warehouse tool, the store reads from there and we do not ask you to enter the same numbers twice. If you have no such system, stock and prices are edited directly in the store admin. The goal is a single source of truth, because double entry always ends in the wrong quantity on the shelf.

What if we have 10,000 products or more?

That is a question of architecture, not catalogue size. Large catalogues need search and filtering that stay fast, product pages generated without manual work, and careful canonical URL handling so that variants and filters do not create thousands of near-identical pages Google treats as duplicates. All three are planned up front. A catalogue that size is not a problem in itself; filters generating endless URL combinations are.

Will we need our own developer after launch?

Not for day-to-day work. Products, prices, content, coupons and orders are all handled in the admin without touching code. A developer is needed for new features, upgrades and integrations, which are occasional jobs rather than a standing role. We offer maintenance, but the store does not stop working if you decline it: the code is yours and any team can pick it up.

E-commerce Consulting & Development

Your online store should sell the way you do business, not the way a template allows. As an ecommerce development agency, we build custom headless online stores that are fully yours: the code, customer data and domain are in your name, with no monthly platform subscription and no fee per order. We first agree on what the store has to achieve, then connect it to your inventory or ERP and to card payments, through Stripe by default or the provider you already use. Online store development starts from €5,000, and the exact price is agreed in writing, fixed per phase, before work starts.

Custom E-Commerce Development

We build your online store on your own code: no Shopify or WooCommerce fees eating into every sale.

What Is Headless E-Commerce?

Headless e-commerce is an architecture that decouples the storefront (what customers see) from the commerce engine (inventory, checkout, payments), connecting them through APIs. This separation gives you complete control over the shopping experience while keeping the backend logic modular and replaceable.

Traditional platforms like Shopify and WooCommerce couple the frontend to the backend, limiting design freedom, checkout customisation, and page performance. A headless storefront built on Next.js 16 with React Server Components renders product pages fast on the server, improving Core Web Vitals scores and Google product ranking.

Headless stores typically load faster than template-based alternatives, and faster pages keep more visitors on the way to checkout.

For growing businesses, the architecture scales horizontally. Adding a mobile app, a B2B portal, or an in-store kiosk consumes the same commerce API without rebuilding the backend.

How Does Checkout Optimisation Reduce Abandonment?

Cart abandonment is the single largest source of lost e-commerce revenue, with the Baymard Institute measuring the global average at 70.19%. The primary causes are forced account creation, limited payment options, and slow checkout flows. Custom checkout engineering addresses all three.

We build single-page checkout flows optimised for mobile-first interaction, where most e-commerce traffic now originates. Every field, validation message, and loading state is engineered to minimise friction.

Payment integration covers both local and global providers:

Regional: local card processors and bank payment providers, integrated natively, not through third-party plugins
Global: Stripe, PayPal, Apple Pay, Google Pay
Multi-currency: Automatic EUR/USD/GBP processing for international sales across the EU and US markets

Guest checkout is the default. Account creation is offered post-purchase, not as a gate. This single change recovers carts that would otherwise be abandoned.

How ERP Integration Eliminates Manual Work

ERP integration in e-commerce is the direct, real-time connection between your online store and your business management system, synchronising inventory, orders, invoicing, and shipping without manual data entry. Disconnected systems are the root cause of overselling, delayed fulfilment, and accounting errors.

We build bidirectional API connections to the ERP systems common in the EU market, scoped per project:

Inventory sync: Real-time stock levels from your ERP (for example Pantheon, Luceed or SAP Business One) reflected on the storefront within seconds
Order processing: New orders push directly into the ERP with correct tax calculations, warehouse assignment, and invoice generation
Logistics: Dispatch to DPD, GLS, DHL, and Croatian Post with tracking numbers written back to the customer's order page, as a possible integration

Once the store is connected to the ERP, manual order entry stops, and so do the errors that come with retyping orders.

Every integration includes error handling, retry logic, and a monitoring dashboard so your team sees sync status at a glance.

Why Do Custom Stores Outrank Platform Shops?

E-commerce SEO is the practice of optimising product pages, category structures, and technical site architecture so that search engines rank your products above competitors. Platform-based stores share templates, URL structures, and rendering limitations; custom stores do not.

A headless storefront built with server-side rendering delivers fully rendered HTML to Googlebot on the first response. No JavaScript execution required, no rendering delay. Product pages include JSON-LD Product schema with price, availability, review ratings, and brand markup, generating rich snippets that make listings stand out in search results.

Category pages use faceted navigation (filters like size, colour, or price that don't create duplicate pages) with proper canonical tags to prevent duplicate content. Internal linking follows a silo architecture, grouping related pages together so search engines see which products matter most.

Full Code Ownership and Long-Term ROI

Code ownership in e-commerce means you hold the complete source code, deploy on your own infrastructure, and pay zero percentage-of-revenue fees to any platform vendor. For a growing store, it is one of the biggest long-term cost decisions you will make.

Shopify Plus charges a minimum of $2,300/month plus 0.2–0.4% transaction fees. For a store generating $1M annually, that exceeds $26,000/year before apps and integrations. WooCommerce avoids platform fees but accumulates costs through premium plugins, managed hosting, and security patching. A custom headless store eliminates all recurring platform costs after the initial build.

Scalability is architectural, not plan-dependent. Your store handles Black Friday traffic spikes through edge deployment and auto-scaling, not by upgrading to a higher pricing tier.

The ROI calculation is straightforward: custom development costs more upfront, and the platform fees you no longer pay grow with your revenue. We run that comparison with your real numbers before you commit.

How Do We Migrate from Shopify or WooCommerce?

E-commerce migration is the process of transferring an existing online store, products, customers, orders, SEO equity, and integrations, from one platform to a new architecture without losing data or search rankings. It is the highest-stakes project in e-commerce development, and the one most agencies underestimate.

What We Handle End-to-End:

Product data migration: all SKUs, variants, images, descriptions, categories, and inventory levels transferred with zero data loss
Order history and customer accounts: purchase history, saved addresses, and loyalty points preserved in full
SEO equity protection: every existing URL mapped to its new equivalent with 301 redirects, so the rankings you have are protected, not reset
Payment gateway transfer: Stripe, PayPal and other payment providers (for example CorvusPay, on request) connected in the new architecture
Staff retraining: your team receives documentation and a hands-on walkthrough of the new CMS before go-live

Why Businesses Make the Switch: Platform fees compound as revenue grows. A store doing EUR 1M/year on Shopify Plus pays over EUR 22,000/year in subscription fees alone, before transaction costs and app subscriptions. A custom headless solution eliminates these recurring costs and removes every restriction on customisation, scaling, and third-party integration.

Timeline: Migration length depends on catalogue size and integration complexity. We confirm your real timeline after reviewing your current store, not before. We run old and new stores in parallel during transition to eliminate downtime risk.

Custom E-Commerce vs Shopify vs WooCommerce

Custom e-commerce, Shopify, and WooCommerce each serve different stages of business growth. Custom headless development delivers maximum performance and zero recurring platform fees. Shopify provides fast setup at the cost of transaction fees and customisation limits. WooCommerce offers more control than Shopify but depends on plugin quality and hosting configuration.
