Streamline Your Distribution for Digital Success

In today’s B2B ecommerce landscape, digital transformation is not a choice—it’s a competitive necessity. Distributors are expected to deliver seamless online experiences, real-time inventory visibility, personalized pricing, and rapid order fulfillment. Epicor Prophet 21 (P21) has long been a trusted ERP for wholesale distributors, offering robust inventory management, order processing, and customer data handling. However, pairing this powerhouse ERP with an equally capable ecommerce platform like BigCommerce creates a game-changing synergy.

When Prophet 21 and BigCommerce operate in silos, inefficiencies mount. Manual processes, delayed updates, and disconnected systems result in lost sales, frustrated customers, and unnecessary overhead. The solution? An integrated ecosystem that syncs your ERP and ecommerce in real time.

This guide explores how integrating Epicor Prophet 21 with BigCommerce transforms B2B operations, improves customer experience, and drives revenue growth—especially when powered by B2Sell’s proven integration platform.

Why Integrate Epicor Prophet 21 with BigCommerce?

Epicor Prophet 21: The Operational Backbone

Epicor P21 serves as the command center of your distribution business, managing:

  • Inventory levels and warehouse operations
  • Customer-specific pricing and credit limits
  • Sales order workflows and invoices
  • Purchase history and supplier relationships

BigCommerce: The Modern Ecommerce Engine

BigCommerce offers a powerful, customizable storefront tailored to both B2B and B2C needs, with features like:

  • Customer-specific catalogs
  • Self-service portals
  • Quote requests and approval workflows
  • Responsive design and API-first architecture

Integration: Eliminating Silos, Maximizing ROI

Integrating P21 and BigCommerce ensures that all business-critical data flows seamlessly between systems—creating a single source of truth. This reduces manual tasks, increases accuracy, and ensures customers see the right prices, stock levels, and order status at all times.

Key Benefits of Prophet 21 and BigCommerce Integration

1. Operational Efficiency & Automation

Manual processes create bottlenecks. Integration automates workflows like:

  • Order Syncing: BigCommerce orders instantly populate in P21.
  • Shipping Updates: Fulfillment data updates in real time.
  • Customer Onboarding: New accounts created in BigCommerce automatically reflect in P21.

Result: Less administrative work, fewer errors, faster processing, and improved productivity.

2. Real-Time Inventory & Pricing Accuracy

Syncing real-time stock and complex B2B pricing structures directly from P21 ensures:

  • No more overselling or outdated inventory displays
  • Accurate customer-specific pricing on every product page
  • Up-to-date promotions, discounts, and contract terms

This builds trust and transparency with your buyers—essential in B2B.

Result: Increased trust, fewer returns, reduced backorders, and satisfied customers.

3. Exceptional B2B Customer Experience

Modern B2B buyers demand a B2C-like shopping journey. Integration enables:

  • Personalized catalogs and pricing
  • Access to full order history and invoices
  • Reorder functionality based on past purchases
  • Real-time shipment tracking

Result: Loyalty through transparency, convenience, and speed.

4. Scalability for Growth

A disconnected system breaks under pressure. Integration prepares you for scale by:

  • Supporting large product catalogs
  • Handling high order volumes
  • Managing growing customer bases

Result: Future-proof operations that scale without proportionate resource increases.

  • Custom business logic
  • Proprietary product codes
  • Custom fields or workflows within P21

🔹 Real-Time Sync Engine

B2Sell uses event-driven synchronization, ensuring that key updates (like stock changes or pricing adjustments) reflect in BigCommerce within seconds—not hours.

Need to convert units, format SKUs differently, or apply tax logic between systems? B2Sell includes data transformation tools that adapt your raw ERP data into web-ready ecommerce data.

🔹 ERP Expertise

We’re not just integration experts—we’re ERP veterans. Our teams understand the nuances of P21’s schema, logic, and custom setups. We speak ERP and ecommerce fluently.

Security, Compliance, and Uptime

B2Sell takes integration security seriously. Key standards include:

  • End-to-end encryption for data transfer between systems
  • Role-based access control to prevent unauthorized changes
  • Data validation checks to ensure accuracy and prevent corrupted syncs
  • 24/7 system monitoring and health checks to avoid downtime

Common Integration Challenges (And How to Overcome Them)

Even with the best platforms in place, the path to a fully integrated ecosystem can face hurdles. Understanding these in advance helps ensure a smoother rollout.

1. Customizations in Prophet 21

Many distributors have customized their P21 system over time. These modifications, while business-critical, can introduce complexity during integration.

Solution:
B2Sell’s integration platform is built with flexibility at its core. It supports mapping to custom fields, workflows, and logic within P21, ensuring your unique business needs are preserved.

2. Data Quality Issues

Data inconsistencies—such as outdated SKUs, duplicated customer records, or incomplete pricing information—can hinder successful integration.

Solution:
Perform a thorough data audit before integration. B2Sell’s team offers data-cleaning best practices and validation tools to ensure a smooth sync.

3. Non-Standard Pricing Structures

Many B2B businesses offer layered pricing: customer-specific, tiered, contract-based, and volume discounts. Capturing and displaying this accurately in BigCommerce can be a challenge.

Solution:
B2Sell’s platform is designed to interpret and sync complex pricing models from P21 directly into BigCommerce’s pricing engine, ensuring 100% accuracy per customer group.

4. Latency and Sync Timing

Timing is crucial. A 10-minute delay in inventory updates could mean overselling fast-moving SKUs.

Solution:
B2Sell supports near real-time and scheduled syncs, depending on business needs. Critical fields like inventory can be updated every few minutes, while non-urgent fields (e.g., product descriptions) can sync hourly or daily.

Real-World Results: What Distributors Gain

  • 80% reduction in manual order entry
  • 100% accuracy in pricing and inventory display
  • 30% faster order processing
  • 2x increase in repeat B2B purchases due to better self-service

Final Thoughts: Integration is No Longer Optional—It’s Strategic

The modern B2B buyer expects speed, accuracy, and a personalized experience. Operating disconnected systems puts you at a disadvantage. By integrating Epicor Prophet 21 with BigCommerce through B2Sell, you empower your business to:

  • Operate more efficiently
  • Deliver a better customer experience
  • Grow without operational chaos
  • Adapt faster to market changes

This is not just a technical decision—it’s a strategic investment in your future.
