Build an online shop — sales-ready, GDPR-safe, without agency overkill
We build professional websites, apps, online shops and custom systems — with the quality of big agencies but without their overhead. Specialised in Germany's small and medium businesses.

In short
Building an online shop starts at €1,499 net (Shopify or WooCommerce, cleanly set up with payment, shipping and legal texts). More complex shops with custom features are quoted at a fixed price.
You want to build an online shop that sells from day one — not a half-finished project you spend months stitching together. You need a system that handles orders, payments, shipping and tax cleanly while being set up to be legally safe for the German market.
Rhein Code builds exactly these sales-ready online shops for retailers in Germany — at a clear fixed price, without the typical agency overkill of endless workshops and inflated invoices. We deliver a shop that loads fast, works on every device and that you can maintain yourself after launch.
Whether you are digitising an existing range, moving off a marketplace to your own shop, or selling online for the first time, we set up the entire sales process. And you talk directly to the developer — no hotline, no middle manager.
Typical challenges
- Ready-made templates look like a thousand other shops
- Setting up payment, shipping labels and tax rates correctly is a lot of work
- GDPR, cookie banner and legal texts are a risk if missing

Online Shops
What your website or solution delivers
The full sales process set up
From cart to checkout to order confirmation, we configure the whole purchase flow. Customers buy in a few steps and you receive clean order data.
All common payment methods
We connect PayPal, card, Klarna, pay-by-invoice and SEPA through providers like Stripe or Mollie. Every customer finds the method they are used to.
Shipping, tax and invoices automated
Shipping zones, VAT and automatic invoice PDFs are configured GDPR- and EU-compliant. Tracking via DHL, DPD or GLS can be added.
Product management without code
In the back office you manage products, variants, stock and promotions yourself. You do not need a developer to keep the shop up to date.
Performance and SEO foundation
We build fast, mobile-optimised pages with clean product markup. These are the technical prerequisites to be found at all on Google and in AI answers.
GDPR, accessibility and legal texts
Cookie banner, privacy policy, withdrawal notice and accessible operation are part of the build. You launch on solid legal footing and avoid common pitfalls.
Multilingual shop possible
On request we set the shop up in German, English and Arabic. That opens international and Arabic-speaking markets without running a second shop.
Scales as you grow
The shop is built so twenty items can become a thousand. Extensions like subscriptions, vouchers or customer accounts can be added later.
In practice
Real-world examples
A retailer wanting off Amazon & co.
A seller pays high marketplace fees and has no access to customer data. We build an own shop that wins back margin and the customer relationship.
A brick-and-mortar shop going online
A local store wants to offer its range online too. We connect stock, shipping and invoicing so online and in-store selling run side by side.
A growing brand with a larger range
A seller with several hundred items needs filters, variants and fast search. We build a shop that stays clear even with a large catalog.
A seller going international
A brand wants to sell beyond Germany to EU and Arabic-speaking customers. We set up multilingual content, currencies and suitable shipping.
Rhein Code
Why Rhein Code for Online Shops
Fixed price from 1,499 € net
You get a clear price before the project starts instead of an open hourly bill. That makes the investment predictable, especially for SMEs.
Sales-ready, not a building site
We hand over a shop that can actually sell — working checkout, payment and shipping. Not a half-built shell you have to finish yourself.
No lock-in
The shop and its data are yours, with no binding agency contract. Moving or expanding is possible at any time.
Direct developer contact
You talk to the person who builds and supports the shop. That removes friction and makes changes fast.
GDPR and EU servers
Customer data lives on EU servers and the shop is set up to be privacy-compliant. In German e-commerce that is both a requirement and a trust advantage.
Three languages from one team
We advise and build in German, English and Arabic. You need no separate provider for international customers.
