Custom E-commerce Your online store · your rules, your profit margins, your future

The budget depends on the scope of the project: the number of products, payment integrations, specific features (subscriptions, bundles, marketplace), and the complexity of the back-office. Unlike Shopify or WooCommerce · which charge a monthly subscription fee and take a commission on each sale · a custom e-commerce solution is a one-time investment in a tool that you own for life. A detailed, personalized quote is provided free of charge after an initial consultation, with no obligation.

It takes 6 to 12 weeks, depending on the complexity of the catalog, payment integrations, and specific features. COSMOS WEB works in three successive phases—scope definition and briefing, design approved by you, and then development—to ensure there are no surprises at the end of the project. A detailed reverse schedule is provided at the outset, and you approve each step before moving on to the next.

Shopify and WooCommerce impose their templates, their fees (up to 2% per transaction on Shopify), their monthly subscriptions, and their plugins that require maintenance—all constraints that pile up as your business grows. A custom e-commerce solution from COSMOS WEB offers the opposite: you have full ownership of your source code, you pay no platform fees, and your store is custom-built for your actual product catalog and customer base—not based on another merchant's template.

By building your store on a proprietary platform (PHP Laravel), the only fees charged on each sale are those from your payment gateway: Stripe charges 1.5% + €0.25 for European cards, and PayPal has its own fee schedule—nothing else. No Shopify commission, no monthly subscription, and no add-ons to purchase every year. On €300,000 in annual revenue, the savings can amount to €6,000 in restored profit margins as early as the first year—without changing anything about your business.

COSMOS WEB integrates payment solutions tailored to your customer base: Stripe, PayPal, bank transfer, installment payments (Alma, Oney), Apple Pay, and Google Pay. PCI-DSS compliance is guaranteed, and card data is never stored on your servers. You can add, remove, or modify payment methods at any time—without restrictions imposed by a third-party platform and without additional integration fees.

Yes—it's a delivery commitment, not a marketing promise. Every e-commerce site delivered by COSMOS WEB includes a custom-built back office: you can add products, update your inventory, process orders, and set up promotions in just a few clicks, with no technical knowledge required. No plugins to buy, no critical updates to manage at 2 a.m., no dependence on a vendor subscription—your store, your rules, your independence.

Technical SEO is built right into the code—it's not an optional feature, nor is it a plugin that needs to be configured after launch. Consistent H1/H2/H3 tags on every product page, clean URLs without duplicate content, Schema.org Product markup for Google rich results, an automatic XML sitemap, and Core Web Vitals optimized natively. Product pages on Shopify typically inherit a generic architecture that often hinders organic search rankings. With COSMOS WEB, every product page is built to maximize its visibility on Google from the very first day it goes live.

The Laravel architecture provided by COSMOS WEB is designed to scale with your business, without having to rebuild everything from scratch at every stage: loyalty programs, multi-store functionality, multi-currency support, marketplaces with resellers, automated accounting exports, and APIs to your third-party tools (ERP, CRM, logistics). You order the modules you need when you need them—on the same technical foundation, without data migration, without changing tools, and without starting from scratch. COSMOS WEB also provides post-launch support for every deployment and offers maintenance contracts tailored to your pace of growth.
