Connecting your business system to a digital sales channel is one of the most important decisions for B2B companies that want to grow digitally. A well-functioning ERP integration gives customers access to the right prices, stock balances and order history without manual intermediaries. In this guide, we walk through architecture, data flows and implementation strategy to help you succeed with your B2B webshop.
Whether you are a wholesaler, manufacturer or distributor, you will get concrete tools to plan and carry out an integration that creates value from day one.Key takeaways: ERP integration with a B2B webshop

- Choose between real-time integration and batch synchronization depending on business-critical needs and system requirements.
- Litium offers open APIs that simplify connecting to all common ERP systems on the market.
- Start with the most important data flows first, then expand the integration iteratively.
- A clear data ownership model reduces the risk of duplicated work and inaccurate information in the sales channels.
What does ERP integration mean for a B2B webshop?
An ERP integration means that your webshop and your business system share data automatically. This can involve product information, customer-specific prices, stock levels, order status and invoice information. When the integration works, you avoid manual data handling and your customers always get current information.
For B2B companies this is especially important, because the buying process often involves complex price lists, agreed discounts and large order volumes. Without a stable connection between the systems, you risk incorrect orders, dissatisfied customers and inefficient workflows.
An integration creates the conditions for self-service, where customers can log in, see their prices and place orders around the clock. That frees up time for the sales team to focus on strategic deals instead of routine tasks.
What architecture options exist for ERP integration?
The architecture of your integration determines how data flows between the systems. There are three main models: point-to-point, integration platform and API-first.
Point-to-point integration
This model connects the webshop directly to the ERP system. It suits smaller organizations with few systems to integrate. The downside is that complexity increases quickly as more systems are connected.
Integration platform
An integration platform acts as a hub between all systems. Data is sent to the platform, which then distributes it further. This provides better scalability and easier maintenance. This model suits companies that plan to grow and add more channels.
API-first architecture
With an API-based architecture, each system exposes its functions through standardized interfaces. This makes it easy to replace or upgrade individual components without affecting the whole. Litium's headless architecture is built on this principle for maximum flexibility.
Which data flows need to be synchronized?
A successful integration is about identifying which data flows are the most business-critical. Here are the most common flows for B2B webshops.
Product data and assortment
Product information is the foundation of all e-commerce. It includes article numbers, descriptions, technical specifications, images and categories. For many B2B companies, base data comes from the ERP while selling content is managed in a PIM system.
The assortment can also be customer-specific, meaning that different customers see different products based on agreement or customer group.
Prices and discounts
B2B pricing is rarely simple. You need to handle list prices, contract prices, volume discounts and campaign prices. The ERP system is usually the master for price data, and the integration ensures that the right price is shown to the right customer in the webshop.
Stock and availability
Customers expect to see current stock balances before they place an order. An integration that updates stock data regularly reduces the risk of selling products that are not in stock.
Orders and order status
When a customer places an order in the webshop, it should be created automatically in the ERP system. Order status, delivery information and tracking should then flow back to the customer. This creates transparency and reduces the number of support cases.
Customer information and accounts
B2B customers often have complex account structures with multiple users, buyers and approvers. The integration needs to handle customer numbers, contacts, delivery addresses and payment terms.
How do you choose the right integration strategy?
The choice of strategy depends on your specific circumstances. Here are the most important factors to consider.
Business requirements and user goals
Start by defining what you want to achieve. Is it about self-service, faster order handling or better data quality? Your goals govern which data flows are prioritized and what level of real time is required.
Existing system landscape
Take inventory of the systems you already have. Which version of ERP are you running? Are there existing integrations to take into account? A modern B2B e-commerce platform should be able to connect to your existing landscape without forcing you to change business systems.
Real-time or batch synchronization
Not all data needs to be synchronized in real time. Prices and stock balances are often time-critical, while product descriptions can be updated overnight. A mixed strategy often gives the best results and reduces the load on the systems.
Internal resources and skills
Do you have your own IT expertise or do you need external help? A simpler integration can be carried out with internal resources, while more complex projects often require an experienced implementation partner.
Step by step: How to carry out an ERP integration
Implementing an integration is a project that requires planning and structure. Here is a proven seven-step process.
Step 1: Define goals and scope
Start by documenting your business goals. Which processes should be improved? Which users should benefit from the integration? Set measurable goals that you can follow up after launch.
Step 2: Map the data flows
Draw up which data should flow between the systems. Define which fields are included, in which direction data should flow and which system is the master for each data type.
Step 3: Choose the integration method
Based on the mapping, you decide whether to use ready-made connectors, build your own integrations or use an integration platform. Litium offers connectors to most common ERP systems such as Monitor, Jeeves, Microsoft Dynamics and SAP (via partners or in-house connectors).
Step 4: Secure data quality
Before the integration is started, you need to ensure that the data in the ERP system is accurate and complete. Remove duplicates, fill in missing values and validate that the structure matches the webshop's needs.
Step 5: Develop and configure
Now the technical work begins. Set up connections, configure mappings between fields and build logic for error handling. Document all configurations for future maintenance.
Step 6: Test thoroughly
Test all flows with real data. Simulate different scenarios such as new customers, price changes and large orders. Involve users from sales and customer service to catch practical problems.
Step 7: Launch and monitor
After launch, you need to monitor the integration continuously. Set up alerts for errors and follow up against your goals. Plan for ongoing maintenance and further development.
What common challenges can arise?
Integrations between the business system and the webshop are complex projects. Here are some challenges to be prepared for.
Data quality issues
If the data in the ERP system is inconsistent or incomplete, it will show in the webshop. Invest time in cleaning up data before the integration is started.
Performance issues
Real-time integrations can affect system performance if they are not designed correctly. Use asynchronous processes and caching where possible to avoid bottlenecks.
Version management
When the ERP system is upgraded, the integration can be affected. Plan for regular maintenance and ensure that the integration is tested after every upgrade.
Organizational silos
Integration is as much about people as it is about technology. Ensure that all affected departments are involved and that there are clear owners for each data type.

Practical tips for a successful integration
Based on experience from hundreds of B2B integration projects, there are a few recurring success factors.
Start simple and build on it
Don't try to solve everything at once. Start with the most business-critical flows and add functionality iteratively. This reduces risk and provides faster time-to-market.
Define clear data owners
Every data type should have a clear owner. This prevents conflicts and ensures that someone is responsible for the quality in each system.
Document everything
An integration that is not documented becomes difficult to maintain. Create clear documentation for mappings, error codes and configurations.
Plan for change
Business systems and webshops evolve over time. Build the integration so that it can easily be adapted when new requirements arise or systems are upgraded.
What does an ERP integration cost?
The cost of an integration varies depending on complexity and scope. The most important cost drivers are the number of data flows, the need for customizations and the chosen integration method.
An integration with ready-made connectors and standard flows can be launched in a few weeks. More complex projects with unique business rules can take several months. The most important thing is to calculate the Total Cost of Ownership (TCO) over time, not just the initial cost.
With the right platform you can reduce both project cost and ongoing maintenance cost. Standardized integrations mean fewer custom solutions that have to be maintained internally.
The future of ERP integrations
The trend is moving toward increasingly real-time and event-driven integrations. The API economy makes it easier to connect systems, and AI-based tools may soon help with data validation and error matching.
For B2B companies that want to stay at the forefront, the key is to choose a flexible architecture that can be adapted as new technologies become available. A composable commerce strategy makes it possible to replace components without rebuilding the entire solution.
