Common Infor ERP and B2B eCommerce Integration Challenges and How to Overcome Them

Infor ERP powers operations for thousands of manufacturers, distributors, and wholesalers, but connecting it to a B2B eCommerce platform rarely goes well in the frontline effort. Data inconsistencies, sync delays, and legacy system quirks have a way of surfacing at the worst possible moments. 

The integration challenges are predictable, which means the solutions are too. This guide walks through the most common obstacles teams encounter when connecting Infor ERP to Magento, Shopify, and BigCommerce platforms, along with practical approaches that generally work in production environments. 

Connecting Infor ERP with B2B eCommerce platforms like Magento, Shopify, or BigCommerce typically runs into a handful of recurring problems: inconsistent data, complex customizations, inventory sync delays, and performance issues. When left unaddressed, broken workflows and eroded customer trust tend to follow. 

The good news? Most issues can be fixed with the right approach. Middleware, API-driven synchronization, thorough testing, and a clear single source of truth can turn a frustrating integration into a genuine competitive advantage. 

When your ERP and eCommerce platform communicate well, you get real-time inventory visibility, automated order processing, and accurate customer data across every channel. B2B buyers expect this level of precision—they place large orders, negotiate custom pricing, and manage complex approval workflows. A disconnected system simply cannot deliver the experience they demand. 

1. Data Inconsistency and Quality Issues 

Infor ERP data often does not map cleanly to eCommerce platform fields. Product attributes, customer records, and pricing structures may use different formats, naming conventions, or hierarchies in each system. 

The mismatch leads to duplicate records, missing information, and conflicting data that confuses both your team and your customers. You might see a product listed with one SKU in the ERP and a different identifier on your webstore—a recipe for fulfillment errors. 

How to solve it: Clean up your data before starting the integration. Information fields are rigidly mapped so that product descriptions, customer data, and prices are balanced as they should be between systems. A captive data handling approach – where a tool acts as an authentic source – helps prevent conflicts at the outset. 

2. Real-time delays in scheduling and order synchronization 

B2B consumers depend on perfect stock availability when ordering. Delays in synchronizing inventory between Infor ERP and your eCommerce platform Stockouts, backorders, and annoyed customers who expected small items to be delivered all at once. 

Overnight batch synchronizations are easier to implement, yet they create windows where your webstore displays outdated inventory counts. A user can order 500 devices that were supposedly sold through another channel hours earlier. 

How to solve it: Use middleware like Infor ION or a dedicated integration platform to sync data in real time or in frequent increments rather than overnight batches. Synchronization every 15 minutes can also significantly reduce stock inconsistencies. 

3. Complex Customizations and Legacy System Constraints 

Older versions of Infor ERP may not connect easily with modern cloud-based eCommerce platforms. Any custom changes that have been added to your ERP over time are likely to make the integration even more difficult, since these changes may have resulted in unique data formats that standard connectors cannot work with. 

In addition, legacy systems usually are not well equipped with APIs, which means that teams must export data by merely using flat files or even manually enter information. Both methods of work are prone to human errors and will affect the speed of the operations. 

How to solve it: Prioritize scalable, API-driven middleware solutions. If your Infor version lacks modern API capabilities, upgrading to a version that supports flexible integration is worth considering. The upfront investment typically pays off through reduced maintenance costs and faster data flow. 

4. B2B Pricing and Tax Complexity 

B2B commerce involves customer-specific pricing tiers, negotiated contracts, volume discounts, and unique tax requirements. Your eCommerce platform needs to display the correct price for each logged-in customer—and that price has to match what the ERP calculates. 

Tax calculations add another layer of complexity. Different customers may have tax-exempt status, operate in multiple jurisdictions, or require specific tax handling based on product categories. 

How to solve it: Configure your integration to pull pricing directly from Infor ERP rather than maintaining separate price lists in the eCommerce platform. For taxes, recalculate within the ERP to maintain consistency and compliance across all channels. 

5. Multi-Channel Data Conflicts 

B2B businesses typically operate via multiple channels, such as direct eCommerce, marketplaces, sales representatives, and EDI connections. Each of these channels can have multiple updates to inventory, orders and customer data, which can create confusion when this information is sent back to the Infor ERP for data synchronization. 

Unless conflict resolution rules are established, there is a risk of overselling your inventory or creating duplicate customer records. Your ERP will be filled with inconsistent data which will require manual cleaning. 

How to solve it: Create rules for which system will prevail in the event of conflicts. The ERP will usually be the master system for determining inventory and price information, whereas the eCommerce platform will be the master system for determining customer facing content. Write down the rules and configure your integration middleware to automatically enforce them. 

6. Lack of Strategic Planning and Technical Expertise 

Underestimating the technical complexity of Infor ERP integration leads to scope creep, budget overruns, and extended timelines. Teams often discover mid-project that their requirements were incomplete or that certain data flows require custom development. 

Integration projects fail more often due to poor planning than technical limitations. Without clear requirements and experienced guidance, even straightforward integrations can spiral into multi-month ordeals. 

How to solve it: Involve developers and integration experts within the planning process itself. Set clean debugging requirements before writing any code. Map every piece of information, discover potential field incidents, and collaborate with experienced integration experts who understand both Infor ERP and your eCommerce platform. 

Tip: Create a detailed integration requirements document that lists every data point, sync frequency, and business rule before selecting a solution. The document becomes your roadmap and helps prevent costly mid-project changes. 

Use Middleware Instead of Custom Hard-Coding 

Custom point-factor integrations may seem fast initially, but they become complex to maintain as the system evolves. Custom code usually breaks when Infor releases updates or your eCommerce platform provides capabilities. 

Middleware platforms provide a translation layer between systems. They handle data mapping, transformation, and error logging without requiring changes to either the ERP or ecommerce platform. The approach also makes it easier to add new channels or systems in the future. 

Popular middleware options for Infor integration include Infor ION, dedicated integration platforms like i95Dev Connect, and specialized connectors designed for B2B ecommerce scenarios. 

Implement Robust Testing Protocols 

Integration testing often gets compressed when projects run behind schedule. The shortcut creates problems that surface only after go-live—when real customers encounter errors. 

Test every data flow thoroughly, focusing on complex scenarios like partial shipments, returns, split orders, and customer-specific pricing. Create test cases that mirror your actual business processes, not just simple happy-path scenarios. 

Key testing areas to cover: 

• Order lifecycle: From cart to fulfillment to returns 
• Inventory updates: Including negative adjustments and transfers 
• Customer data: Account creation, updates, and hierarchy changes 
• Pricing scenarios: Contract pricing, volume discounts, and promotional pricing 
• Tax calculations: Multiple jurisdictions and exempt customers 

Establish a Single Source of Truth 

Decide which system owns each type of data. Ambiguity about data ownership creates conflicts and makes troubleshooting difficult when discrepancies appear. 

Data Type	Recommended Owner	Rationale
Inventory levels	Infor ERP	Central warehouse management
Product pricing	Infor ERP	Contract and tier management
Customer accounts	Infor ERP	Credit and payment terms
Product content	Ecommerce/PIM	Marketing-focused descriptions
Order status	Infor ERP	Fulfillment tracking

The clarity simplifies integration logic and reduces the chance of conflicting updates overwriting correct information. 

Monitor and Audit Continuously 

Integration is not a one-time project. Data flows require continuous tracking to catch errors before they affect customers or operations. 

Set up computerized indicators for synchronization screws, data discrepancies, and unusual styles. Review integration logs regularly to be aware of common issues that may result in underlying issues with best of records or device configuration. 

Schedule periodic audits to verify that data remains consistent across systems. Even well-designed integrations can drift over time as business processes evolve or users find workarounds. 

Build for Scalability from Day One 

Your integration requirements will grow as your business expands. A solution that works for 1,000 orders per month may struggle with 10,000. Planning for growth by choosing platforms and architectures that can scale prevents painful re-architecture later. 

Consider factors like API rate limits, database performance, and middleware throughput when designing your integration. Building in headroom now saves significant effort down the road. 

The best integration approach depends on your specific Infor ERP version, eCommerce platform, and business requirements. There is no universal solution that works for every scenario. 

Factors to evaluate: 

• Infor version and API capabilities: Newer versions offer better integration options 
• eCommerce platform flexibility: Some platforms have pre-built Infor connectors 
• Data volume and sync frequency: High-volume businesses benefit from robust middleware 
• Internal technical resources: Consider whether you can maintain custom solutions long-term 
• Budget and timeline: Balance upfront costs against long-term maintenance 

For complex B2B scenarios with customer-specific pricing, multi-warehouse inventory, and high order volumes, a dedicated integration platform typically provides the best balance of flexibility and reliability. 

Integrating Infor ERP with B2B eCommerce platforms presents real challenges—but none of them are insurmountable. Data inconsistencies, synchronization delays, legacy barriers, and price complexity all have proven solutions when approached with proper planning and the right tools. 

The key is treating integration as a strategic initiative rather than a technical checkbox. Invest time in requirements gathering, choose middleware over custom code, test thoroughly, and plan for ongoing maintenance. 

When done right, Infor ERP integration transforms your B2B eCommerce operation. Real-time inventory accuracy, automated order processing, and consistent customer data across channels create the seamless experience your buyers expect.
