B2B e-commerce is fundamentally different from selling to end consumers. Customer-specific pricing, volume discounts, multi-level order approvals, connections to ERP and accounting systems: the technical and operational requirements for a B2B online shop are substantial. As a specialized B2B e-commerce agency, we combine deep understanding of wholesale and manufacturing business processes with proven technical expertise in Shopware development, REST API architecture and enterprise system integration. The result: digital sales platforms that mirror your internal workflows, accelerate ordering and free your field sales team from administrative overhead.

Six Core Competencies for Your B2B Success

Every B2B project brings its own requirements: different product structures, different ERP landscapes, different approval logic. Across 50+ projects, we have learned what matters most and organized that expertise into six coordinated service areas.

Shopware B2B Development

Custom B2B shops built on Shopware Community Edition: tailored plugins for customer-specific price lists, tiered pricing, minimum order quantities and role-based access control. The API-first architecture stays flexible for headless frontends and multi-channel.

ERP and Inventory System Integration

Bidirectional synchronization with SAP Business One, SAP S/4HANA, Microsoft Dynamics 365 Business Central and DATEV. Through REST APIs and message queues, product master data, stock levels, customer pricing and order status stay consistent across all systems.

Mehr erfahren

B2B Portal and Self-Service

Complete B2B customer portals with individualized catalog views, order history, quote management, claims handling and digital order approval. Your customers order around the clock without tying up your inside sales team.

Mehr erfahren

Performance and Scalability

B2B catalogs with 50,000, 200,000 or more products demand carefully designed architectures. We optimize database queries, deploy caching with Redis and Varnish, and use Elasticsearch for faceted search. Page load times under two seconds are our standard.

Strategic E-Commerce Consulting

Before the first line of code, there is analysis: examine existing sales processes, identify automation opportunities, jointly define a roadmap. From requirements specification through platform selection to go-live planning.

Maintenance, Monitoring and Support

A B2B shop is business-critical infrastructure. Our managed service includes proactive monitoring, security updates, performance tracking and defined response times. We identify issues before your customers notice them.

B2B e-commerce does not work as an extension of a B2C shop. Pricing logic, approval chains and ERP connectivity belong in the architecture from the ground up, not bolted on afterward.

Our architectural principle from 50+ B2B projects

Industries We Serve in B2B E-Commerce

B2B e-commerce is not a one-size-fits-all proposition. Each industry places unique demands on product data, order processes and system landscapes. Our experience spans multiple industrial sectors, from wholesale through manufacturing to technical trade, and we know from practice which industry-specific requirements must be considered when designing and building a B2B shop. This specialization enables us to make the right architectural decisions from day one and avoid common pitfalls. As part of our strategic e-commerce consulting, we analyze the industry-specific conditions and derive concrete recommendations for your project.

Wholesale and Distribution

Fast order entry for large volumes, tiered pricing by purchase volume, framework agreements with automatic conditions and connection to warehouse logistics systems. Our solutions enable your customers to place orders with hundreds of line items in minutes.

Mechanical Engineering and Industry

Spare part identification through bills of materials and assembly navigation, technical drawings as supplementary product information, configuration logic for variants and accessories, plus integration into existing ERP systems running SAP or Microsoft Dynamics.

Electrical Engineering and Electronics

Standards-compliant product classification per ETIM and ECLASS, extensive filtering by technical attributes, datasheet downloads and compatibility checking. Integration of BMEcat catalogs for standardized data exchange.

Chemicals and Hazardous Materials

Automatic provision of safety data sheets, GHS-compliant hazardous substance labeling, quantity restrictions per hazard class and legally compliant documentation of all order transactions. Transport and storage regulations are factored directly into the ordering process.

Automotive and Suppliers

EDI connections following VDA standards, just-in-time and just-in-sequence ordering processes, delivery schedule management and quality documentation per IATF 16949. Seamless integration into existing supply chain systems for on-schedule production.

Technical Trade

Advisory-intensive products with comprehensive product information, comparison functions, technical datasheets and cross-selling based on compatibility. Self-service portals for regular customers with personalized assortments and special conditions.

Why B2B Is Fundamentally Different from B2C

Many companies underestimate how profoundly B2B commerce requirements differ from standard retail. The distinction goes beyond target audiences to fundamentally different business logic. In B2B, long-term business relationships, individually negotiated terms and complex organizational structures define the purchasing process. A procurement professional in a manufacturing company has different expectations than an end consumer: they need precise technical specifications, standardized product designations, reliable availability data and the ability to place orders by SKU number rather than through visual product browsing.

Moreover, cart sizes in B2B are typically many times larger than in B2C. Orders with 20 to 200 line items are the norm, not the exception. Decision-making processes are multi-layered: a purchaser creates the cart, the department head approves it, and above a defined order value, executive management must sign off. These approval chains must be technically implemented in the shop system, including email notifications, dashboard overviews and audit-proof logging.

Order volumeSingle items, low basket valuesLarge quantities, high basket values, repeat purchasers

These differences illustrate why B2B e-commerce cannot function as an extension of a B2C shop. The technical architecture, data structures and process logic must be designed from the ground up for B2B requirements. This is precisely where our core expertise lies: we understand the business logic behind the technical requirements and translate it into performant, maintainable software solutions. Our services overview provides a detailed description of all areas in which we support you.

A B2B Portal That Frees Your Inside Sales Team

In the customer portal, your business clients see open orders, pending approvals and their personal terms at a glance. Orders are linked to role and budget, and approvals are logged in an audit-proof manner. Learn more on our B2B portal page.

  • Order overview with status, requester and approval stage
  • Roles and budgets per company account and user
  • Quick ordering by SKU number or CSV upload

Our Project Approach: From First Conversation to Go-Live and Beyond

Transparency and predictability are central to how we work. Every project follows a structured process that ensures requirements are captured cleanly, implemented correctly and supported reliably in ongoing operations. At the same time, we remain agile enough to respond to evolving requirements during the project.

The Path to Your Own B2B Shop: What Decision-Makers Need to Know

Launching a B2B online shop is more than an IT project. It is a strategic decision that affects sales, procurement, IT and executive management in equal measure. Many of our clients face the question of how to take the first step without jeopardizing existing sales processes or overwhelming their teams. Our experience shows: the key lies in a phased approach. Rather than implementing everything at once, we recommend an MVP approach (Minimum Viable Product) where the most critical features go live first and the system is expanded incrementally. This approach has proven itself across 50+ projects and minimizes both financial risk and organizational strain on your business.

A common concern when introducing a B2B shop is acceptance by the field sales team and existing customers. Our project experience shows that the key lies in early involvement of all stakeholders. When field sales representatives understand the shop as a tool that relieves them of routine work rather than as competition for their role, acceptance increases significantly. At the same time, we offer training for your customers that eases the transition to the digital ordering channel. In practice, the combination of a self-service portal and personal advisory through field sales proves especially successful.

A typical first milestone covers the product catalog with customer-specific pricing, a core ordering function and the connection to your ERP system for order data transfer. Building on that, subsequent phases add features like approval workflows, order templates, quick ordering via CSV upload and extended self-service capabilities. This approach reduces project risk, enables early user feedback and distributes the investment over a longer timeframe.

Multi-Level Order Approval, Cleanly Modeled

Above a defined order value, the approval process kicks in automatically: the requester creates the cart, the department head reviews it, and beyond a threshold executive management decides. Every step triggers a notification and is logged in an audit-proof manner.

  • Thresholds per company account, user or cost center
  • Email notification and dashboard alert at every stage
  • Complete logging for internal review and audits

Typical Results After the First Year of Operation

Our clients regularly report measurable improvements after launching their B2B shop: phone-based order volume typically drops by 40 to 60 percent (project experience) as regular customers adopt the self-service channel. The error rate in orders decreases significantly because SKUs, quantities and terms are validated by the system. At the same time, order frequency increases because customers can place orders around the clock, independent of office hours and field sales visits.

Additionally, we observe that average order values through digital channels frequently exceed those from phone-based ordering. This is because customers in the shop receive structured cross-selling suggestions, accessory recommendations and compatibility hints that often get overlooked in phone conversations. The combination of reduced process costs, increased order volume and improved data quality makes investing in a B2B shop one of the most economically impactful digitalization measures for mid-market companies in trade and manufacturing. From our base in Lower Saxony, we serve companies in Hannover, Hildesheim, Braunschweig and throughout the region. Learn more about our team and approach on the About page.

Technology Stack: A Foundation for Long-Term Investment Security

The right technology choice determines how flexible, performant and future-proof your B2B shop will be. We consistently build on Shopware Community Edition as our technical foundation, complemented by proven open-source components. This combination gives you full control over source code, hosting and future development without dependency on any single vendor. Unlike proprietary SaaS solutions, with Shopware CE you retain full data sovereignty: all customer data, order histories and custom adaptations reside on your own servers. This is particularly relevant for companies that must meet strict compliance requirements or whose clients demand contractual data residency provisions.

One Data Flow That Keeps Every System in Sync

Your shop is not an isolated system. Through REST APIs and message queues, we connect it bidirectionally with your inventory management so that product master data, prices, stock levels and orders flow consistently in both directions. Learn more on our integrations page.

  • Products, prices and stock from the ERP into the shop
  • Orders and order status written back into the ERP
  • Fault-tolerant synchronization with automatic retries

Shopware CE with Symfony

Shopware Community Edition is built on the Symfony framework, providing a clean, extensible codebase. The plugin system enables modular customizations without altering the core, ensuring long-term update compatibility.

Elasticsearch and Redis

Elasticsearch delivers lightning-fast search results even with hundreds of thousands of products. Redis handles session management, HTTP caching and database offloading. Together, both systems ensure page load times that satisfy even the most demanding procurement professionals.

REST APIs and Message Queues

Standardized REST APIs connect your shop with SAP, DATEV and other systems. Message queues decouple time-critical processes and ensure that no data record is lost even during high order volumes.

Docker and CI/CD Pipelines

Containerized development environments ensure identical conditions across all stages: development, staging and production. Automated pipelines ensure that only tested code reaches deployment.

MariaDB and Varnish

MariaDB as the database server provides the robustness needed for complex price calculations and large datasets. Varnish as an HTTP accelerator reduces server load and speeds up delivery of frequently requested pages.

PHPUnit and PHPStan

Automated testing with PHPUnit secures functionality with every change. Static analysis with PHPStan at the highest level catches potential errors before runtime and maintains code quality on an ongoing basis.

The success of a B2B e-commerce project depends significantly on the quality of the data foundation. Product information, price lists, inventory levels and customer master data must be consistent and up-to-date for the shop to function reliably. Before every project start, we therefore analyze existing data quality and develop cleansing strategies where needed. A B2B shop is only as good as the data feeding it. Our integration solutions ensure this data flows automatically and reliably between all systems.
