What does building an online shop with nextlevels cost?

It depends heavily on scope. A manageable shop based on Shopware typically starts in the low five-figure range, while complex B2B or headless projects with ERP and PIM interfaces sit above that. On top come running costs for hosting, licenses and maintenance as a separate line item. You get a concrete fixed-price offer after a short discovery in which we clarify requirements, interfaces and data volumes.

How long until my shop goes live?

A clearly scoped shop usually takes from a few weeks to a few months. The range is wide because it depends on the number of interfaces, the complexity of your assortment and the data migration. We work in iterations: you see a working state early and give feedback, rather than only seeing the finished result at the end.

Which shop system do you recommend – Shopware, headless or something else?

Our focus is Shopware, because as an open-source system it is powerful, extensible and well established in the German mid-market. We recommend headless architectures (Shopware as backend, your own frontend) when you need maximum frontend freedom or special performance. We make the decision based on your requirements, not on principle – a simple shop doesn't need a headless setup.

Can you migrate my existing shop?

Yes. We migrate existing shops including product data, customers, order history and URL structure. The URLs and redirects in particular are crucial so your SEO rankings don't collapse during the move. Before migrating we analyze your current shop and plan the move so ongoing operations are disrupted as little as possible.

Do you support B2B, B2C and D2C equally?

Yes. In B2C, conversion, speed and a frictionless checkout matter most. In B2B, requirements such as customer-specific price lists, tiered pricing, order approvals, quotation features and ERP integration come into play. We support D2C brands from brand staging to the logistics interface. We build the shop around your business model, not the other way round.

How do you ensure performance and scalability?

Performance isn't an afterthought for us but part of the architecture. We optimize for good Core Web Vitals, use caching, a CDN and clean database indexes, and test behavior under load. That keeps your shop fast and stable even during load peaks such as sales campaigns or Black Friday.

What about data protection, security and payment processing?

We build shops GDPR-compliant and integrate payments via certified payment providers, so no sensitive card data sits on your server. Updates, secure configuration and a roles-and-permissions concept are standard for us. In e-commerce, security isn't an optional add-on but a prerequisite for trust and conversion.

Who owns the shop – does vendor lock-in arise?

You own everything: code, configuration, data and content. Because we build on open-source technology like Shopware, you're not tied to proprietary systems and could in principle hand operations to another team. We document cleanly – vendor lock-in is not our business model.

Build a Scalable Store Platform

Challenges you'll recognise

Your current shop platform makes every new feature a gamble — changes risk breaking something else in production.
You're unsure which platform fits your business model long-term and worried about making a costly wrong call.
After launch, nobody systematically handles updates and security patches until something breaks in production.

Services in detail

Good to know

Platform choice is infrastructure
Choosing between Shopware 6 Storefront, a headless setup, or a hybrid has direct consequences for development costs, deployment complexity, and how much your own team can change independently. Switching after go-live is expensive — that's why thorough analysis before the decision pays off.
Modular architecture protects production
When shop-specific extensions are cleanly separated from the Shopware core, platform updates can be applied without overwriting custom code. This is the main reason some shops stay up to date effortlessly while others spend weeks fixing regressions after every update.
Short sprints reduce project risk
Instead of a single large release after months of development, two-week sprints allow feedback to surface early and course corrections before they get expensive. Risk doesn't live in individual features — it lives in unvalidated assumptions, which short cycles expose much sooner.

Frequently asked questions

Which e-commerce platforms do you develop?

Our focus is on Shopware 6 — both as a classic storefront and as a headless setup with a decoupled frontend. We also support migrations from legacy systems and work with you to evaluate which platform best fits your business model and growth plans.

How long does it take to develop a new online shop?

It depends heavily on scope: a close-to-standard Shopware shop can often go live in 8–12 weeks, while a complex B2B project with custom workflows can take considerably longer. After an initial requirements workshop, we define a realistic timeline together and stick to it.

Can we migrate an existing platform without disrupting ongoing operations?

Yes, that's a core scenario for us. We plan migrations so your current shop runs fully until the go-live date. Data migration, redirect management, and parallel testing phases are standard procedure to make the transition seamless and risk-free.

Do you take care of ongoing maintenance after launch?

Yes, we offer maintenance contracts with defined SLAs that cover regular updates, security patches, and a prioritized support channel. Many of our clients have been with us since their first launch, and we grow as a partner alongside their business.

How do you ensure the shop stays stable during traffic spikes?

We run load tests before launch to simulate peak scenarios and tune the server infrastructure accordingly. Caching layers, horizontal scaling, and a CDN ensure your shop performs reliably even during seasonal spikes like Black Friday — without last-minute scrambling.
