eCommerce Site

An online store that sells — not an online catalog waiting.

An online store is not a PDF catalog with a "Buy" button. It is your digital sales force, your 24/7 storefront, and often, your main revenue channel.

At Mermio, we don’t just set you up with a WooCommerce theme and 50 shaky plugins. We develop your eCommerce platform tailored to your needs, with a technical architecture designed to scale, convert, and maintain — even when you receive 1000 orders a day.

We support you at every step:

Choosing the technical stack (Laravel, Shopify, PrestaShop, or headless depending on your needs)
Design optimized for conversion (checkout funnel, product sheets, cross-sell)
Payment integration (Stripe, PostFinance, Twint, etc.)
Inventory management, variations, promotions, discount codes
ERP/CRM synchronization (if you have one)
Technical SEO optimization (speed, product indexing, rich snippets)
Enhanced security (PCI-DSS, SSL, customer data protection)
Advanced analytics and tracking (conversions, abandoned cart, remarketing)

And above all: we're here after delivery. No "good luck with your sales". We help you optimize, fix, and add features — with no hidden costs.

Start a project

Which platform do you use to develop an online store?

It depends on your project. We mainly work with Laravel for custom stores with specific needs, but we can also work with Shopify or PrestaShop depending on your context. We help you choose the most suitable stack — not the one we prefer by default.

What payment methods can you integrate?

We integrate the common solutions in Switzerland and Europe: Stripe, Twint, PostFinance, and others according to your needs. If you already have a contract with an acquirer, we adapt. If you are starting from scratch, we guide you to the simplest and least expensive solution for your volume.

My product catalog is already set up elsewhere — can we migrate it?

Yes. Catalog migration, product data import, retrieval of order histories — this is a step we integrate into the project from the start. We avoid data loss and duplicates, and we ensure everything is correct before going live.
