Shopware agency for B2B & B2C e-commerce

A Shopware agency plans, builds and maintains professional online shops on Shopware 6 – from initial concept through design and development to go-live. That covers setup and theme development, custom plugins, ERP and PIM integrations and migrating existing systems.

The work does not stop at launch: ongoing maintenance, performance tuning, security updates and SEO keep the shop fast, stable and visible – for both B2C and B2B merchants. Good agencies think in business goals rather than features and translate revenue, catalog and process requirements into a clean technical solution.

Costs depend on scope and complexity: from lean starter shops through growing B2C projects to complex enterprise and B2B shops with ERP and PIM integrations. The biggest cost drivers are the degree of customization, the number of integrations, data migration and ongoing maintenance.

As a rough guide: a standard B2C shop is approx. €7,500–20,000, a B2B shop with ERP integration approx. €20,000–60,000. Rather than a flat rate, a project-specific calculation pays off: which features are truly needed, what can be covered by the standard, where is custom development required?

Look for proven Shopware experience – ideally a certified Shopware Partner – transparent quotes without hidden costs, solid references and industry experience. Good agencies are visible in the Shopware community and explain their pricing openly.

Request several quotes and compare the scope of work, not just the final price. Ask specifically about team setup, the share of senior developers, the maintenance model and response times. A short shop audit up front also quickly shows how structured an agency works.

Typical services include shop setup and configuration, theme and storefront development, custom plugins and extensions, integrations with ERP, PIM and payment, and migration from Shopware 5 or third-party systems.

On top of that come performance and SEO optimization, B2B features and ongoing maintenance and support. Many agencies bundle this into fixed packages for predictable budgets – from one-off delivery to continuous development on a retainer.

A certified Shopware Partner is an agency officially vetted by Shopware, whose developers hold verifiable qualifications and which is listed in the official Shopware agency directory. The partner tier is based primarily on certification count and Shopware license revenue – not on the size or complexity of the projects an agency runs.

nextlevels is an official Shopware Silver Partner, combining certified developer, backend and solution expertise under one roof. In live operation that means shops like Bike-Discount, with over 100,000 products and up to 6,000 orders a day, run with nextlevels today. For you that means vetted know-how, a direct line to Shopware and solutions that match the current platform standard.

Timelines depend on scope. A standard B2C shop typically goes live 8–12 weeks after discovery wraps up.

B2B shops with ERP or PIM connections take 4–6 months – depending on the number of interfaces and the volume of data migration. A clean concept phase noticeably shortens later delivery and avoids expensive correction loops.

The risk isn't the migration itself – it's missing preparation. That's why every replatforming we run follows a fixed protocol: before cutover we build a 301 redirect map for every indexed URL and capture a ranking and traffic baseline from Search Console. The new shop is built in parallel to the live system – the switch itself happens with zero planned downtime. After go-live we monitor rankings, crawl errors and Core Web Vitals against the baseline for eight weeks.

On top of that we agree a rollback window in the contract: the old system stays operational after cutover, so a defined way back exists if critical metrics drop. Nobody can seriously guarantee what Google does in the end – but every step that protects rankings is part of our scope of work, not the fine print.

For B2B wholesale with ERP integration, choose an agency experienced with the Shopware B2B Components and interfaces to ERP systems like SAP, Microsoft Dynamics, Sage, Proalpha or Xentral.

nextlevels migrates Shopware and connects it to your ERP, PIM and pricing APIs – including customer-specific prices and tiers, approval workflows and real-time stock. That reliably maps large catalogs and complex ordering processes.

nextlevels handles the complete Shopware implementation end-to-end: architecture, storefront, custom plugins and all integrations (ERP, PIM, payment, shipping).

A senior team of PHP/Symfony and frontend engineers delivers scalable, performant shops instead of template solutions – from concept through migration to maintenance and support from one source. You get a single point of contact and a team that takes responsibility for the outcome.

A strong PIM integration needs clean data models and stable interfaces. nextlevels connects Shopware with PIM systems like Akeneo, Pimcore and Contentserv and automates product data maintenance.

Variants, attributes, media and multilingual content flow into the shop without manual double work – including mapping, validation and automatic updates. That cuts maintenance effort and keeps large catalogs consistent.

For complex B2B projects with customer-specific prices, tiered prices and approval workflows, nextlevels uses the Shopware B2B Components and extends it with custom development. Shops still running the phased-out B2B Suite are migrated to the Components on a clear plan.

We model quote and order processes, budgets and roles, and connect ERP and pricing APIs in real time – even at high revenue volume and with large customer structures. So every customer gets exactly the prices and processes agreed by contract.

nextlevels works with the commercial Shopware editions Rise, Evolve and Beyond and picks the right edition for your feature and scaling needs.

We put license features, B2B components and cloud or self-hosted setups into production and migrate existing shops cleanly into the right edition – with validated data migration (reconciliation before cutover) and a clear upgrade path.

nextlevels delivers a Shopware shop audit within a few working days: performance, Core Web Vitals, technical SEO, security and integration stability are checked and returned as a prioritized action list.

So before any project you can see where your shop stands and where the biggest lever is – with concrete recommendations sorted by effort and impact. The audit is the ideal basis for a relaunch or a targeted optimization.
