FAQ
Custom E-commerce - FAQ
Custom e-commerce development starts from €2,000 for stores with tailored product catalogs, custom checkout, and essential integrations. Complex platforms with inventory management, multi-vendor capabilities, or subscription models typically range from €5,000–€15,000+.
Custom development makes sense when you need unique checkout flows, complex pricing rules, proprietary integrations, multi-warehouse inventory, subscription logic, or features that no plugin can provide. You own the code completely and are not limited by platform restrictions or monthly fees.
We integrate any payment gateway - Stripe, PayPal, GoPay, Comgate, bank transfers, cash on delivery, and invoice payments. We also handle multi-currency support, subscription billing, and split payments for marketplace models.
Yes. We migrate products, customer data, order history, and SEO rankings from existing platforms to your new custom store. URL redirects preserve your Google rankings, and customers experience a seamless transition.
A focused custom store takes 6–10 weeks. Complex platforms with multiple integrations, custom admin panels, and advanced features take 10–16 weeks. We use agile methodology with regular demos so you see progress every sprint.
E-commerce Built Around Your Business, Not a Template
There comes a point where off-the-shelf e-commerce platforms start holding you back. Plugin conflicts, checkout limitations, monthly fees that scale with revenue, and design constraints that make your store look like everyone else's. Custom e-commerce development eliminates all of these problems by building your online store around your specific business logic, not the other way around.
Kosmoweb develops custom online stores using modern frameworks like React and Next.js for the frontend and headless commerce architectures for the backend. This approach delivers blazing fast performance, complete design freedom, and the ability to integrate with any ERP, warehouse system, accounting software, or marketing platform your business relies on.
Our custom e-commerce projects include everything from product catalog architecture and search functionality to custom checkout flows, payment gateway integration, shipping calculators, and admin dashboards. Unlike Shopify stores where you adapt your process to the platform, we adapt the platform to your process. The comparison between Shopify and custom solutions often comes down to scale and uniqueness of requirements.
We have built custom stores for fashion brands, B2B distributors, food delivery services, and digital product sellers across Prague and beyond. Every project includes SEO optimization, mobile-first design, security hardening, and thorough testing. Post-launch website management ensures your store evolves with your product catalog, market demands, and growth ambitions.
