BigCommerce enables rapid online sales, but manufacturers and distributors must connect these orders with downstream ERP, WMS and fulfillment systems for a complete business workflow. EDI order routing maps order data between the BigCommerce storefront, ERP platforms and trading partners, controlling business logic, routing and validation so that every order reaches fulfillment, accounting and customer care teams efficiently. With so many different possible connections and data requirements, using an experienced managed service like BOLD VAN reduces the risk of manual errors, exceptions and chargebacks while giving finance and IT a clear, standardized process from order capture to invoice.
How EDI order routing bridges BigCommerce and ERP fulfillment
EDI order routing translates online sales from BigCommerce into formats your ERP, WMS or TMS can use, and ensures trading partners receive the documents they require. This process typically includes transforming BigCommerce orders into EDI 850 purchase orders, exchanging acknowledgments (855), sending advance ship notices (856), submitting invoices (810) and handling functional acknowledgments (997). Each step is controlled by business rules set in the mapping, routing and integration layer.
BOLD VAN specializes in mapping these flows, supporting both EDI-to-API and API-to-EDI connections, and integrates with ERP systems like SAP, Oracle, NetSuite, Infor CloudSuite and ShipHero, among others. Our approach lets your direct-to-consumer and wholesale orders follow appropriate paths, applies partner-specific requirements, and returns delivery or failure notifications whenever manual intervention is required.
Key takeaway: A 997 functional acknowledgment only reports whether a document passed the receiver's syntax check, not that the order itself was accepted or will be filled. Always confirm downstream completion, not just EDI delivery.
Defining the data structure: Mapping BigCommerce to ERP
Order routing works by mapping business data between BigCommerce and your ERP or fulfillment platform. This mapping requires careful cataloging of how each field in the BigCommerce storefront aligns with required business logic, ERP fields and EDI transaction sets. For example, BigCommerce orders may use store-level SKU numbers that need cross-reference to the item numbers or UOMs defined in your ERP. Shipping details, customer references, and line items must be validated and transformed to match each system’s requirements and your trading partner’s implementation guide.
| Business information | Possible source | Routing consideration |
|---|---|---|
| Order identity | BigCommerce order record | Keep consistent identifiers across storefront, integration and ERP |
| Product identity | Store SKU or partner item reference | Cross-reference SKUs if partner and storefront identifiers differ |
| Quantity and units | Order lines, ERP item master | Check conventions and unit conversions before fulfillment |
| Ship-to address | BigCommerce customer address | Verify required address and compliance for each partner |
| Inventory status | ERP, WMS | Define which system is authoritative for availability |
| Status updates | ERP/WMS/carrier API | Route tracking and shipment updates back to the correct place |
Mapping is not just copying data; it interprets business meaning, applies any required conversion or validation logic, and ensures all exceptions and errors are handled with clear rules. Before implementation, document all mapping and validation rules, and confirm them against both your ERP documentation and each trading partner’s latest implementation guide.
Step-by-step: Connecting your BigCommerce storefront to your ERP
A reliable integration project follows these steps:
- Document all order paths. List online, wholesale, marketplace and exception or return flows. Track which originate in BigCommerce, EDI feeds or elsewhere.
- Assign ownership of each data type. Decide which system owns customer, product, inventory, pricing, fulfillment and financial data.
- Gather all documentation. Collect your ERP specs, BigCommerce integration docs, and each trading partner's EDI implementation guides to ensure every routing rule is accurate.
- Define your EDI document set. Identify which documents are required per route and partner, such as 850, 855, 856, 810, and 997.
- Map and document routing rules. Set explicit criteria for differentiating sales channels, fulfillment sites, order types, and exception handling.
- Build and test mappings. Use real and test orders to check routine, missing, and edge-case flows: split shipments, partial fills, returns and repeated messages.
- Reconcile and validate outcomes. Trace each order from BigCommerce to ERP to fulfillment, ensuring status and error handling work as designed.
- Plan for ongoing support. Assign roles for reviewing notifications, requeueing documents, correcting master data, and trading partner escalation.
With BOLD VAN, new maps are typically ready to test in about two days and new connections are typically live within a business day. VAN migrations typically take about two weeks. Our US-based team tracks every document in the portal, where you can search, requeue and report, with notifications for exceptions or issues.
BOLD VAN supports mapping and integration for both legacy EDI and modern API-driven platforms. This includes BOLD Integration for ERP, WMS and even e-commerce API endpoints, offering a managed bridge between online sales and back-end fulfillment.
Common pitfalls in EDI order routing
Assuming one rule fits every channel
Treating all orders the same often backfires, since direct-to-consumer, wholesale and marketplace flows have different requirements for validation, fulfillment and post-sale support. Routes, document sets and business logic should be explicitly defined per channel.
Missing or mismatched identifiers
SKU mismatches, customer ID confusion or incomplete address references can cause orders to hang or fail downstream processing. Cross-reference tables and lookup logic should be included in every mapping design.
Assuming EDI delivery means business acceptance
An EDI 997 or API response only shows technical completion. Business rules must validate fulfillment, billing and exception management to truly complete the process.
Testing only for routine transactions
Edge cases like partial shipments, multiple fulfillment sites or returns reveal gaps in routing or mapping that are only visible with scenario-based testing. Always review not just "happy path" outcomes, but every exception likely to occur in production.
Unclear data ownership and exception response
If no one owns incorrect or failed records, troubleshooting becomes a bottleneck. Assigning clear support ownership for each exception type minimizes operational impact.
Best practices for EDI-integrated order fulfillment
- Use the most current documentation for every partner and system before building mappings
- Keep order, SKU and location IDs clean and synchronized with controlled cross-references
- Validate all required data in both source and destination systems, not just the outbound document
- Test both standard and edge-case scenarios, including returns, partial fulfillment and errors
- Document mapping rules, ownership and exception escalation paths
- Monitor both technical and business success, using the EDI portal or system logs for full traceability
- Consider managed EDI services to reduce the internal burden of keeping maps current and support continuous changes from partners or ERP releases
Many manufacturers and distributors leverage managed services such as BOLD VAN to keep up with EDI map changes (typically ready to test in about two days) and reduce key-person dependency when integration rules evolve. BOLD VAN helps reduce the risk of chargebacks and ensures that every BigCommerce order flows smoothly into ERP, fulfillment and accounting without forcing teams to rekey data or chase down lost transactions.

Frequently asked questions
Does BigCommerce support EDI natively?
BigCommerce provides platform and API capabilities, but EDI order exchange generally requires an integration layer that translates between the storefront's data and each trading partner's EDI requirements.
Which EDI documents are used in BigCommerce order routing?
Common documents include the 850 purchase order, 855 purchase order acknowledgment, 856 advance ship notice, 810 invoice and 997 functional acknowledgment. The exact set depends on each trading partner's implementation guide.
What does a 997 functional acknowledgment confirm?
A 997 tells the sender whether the receiver's syntax check accepted or rejected the document. It does not confirm that the order or its contents were accepted.
How long does a BigCommerce EDI integration take?
Timing depends on the ERP, trading partners, document set and testing requirements. With BOLD VAN, new maps are typically ready to test in about two days, new connections are typically live within a business day and VAN migrations typically take about two weeks.
