SAP ECC and BigCommerce
Integration Agency & Consultants
At scale, the distance between SAP ECC’s legacy IDoc structures and BigCommerce’s storefront often leads to delays in fulfilment and inaccurate B2B pricing. These issues typically surface when manual processes for managing customer-specific discounts fail to keep pace with order volume. We focus on the integration between your SAP ERP and BigCommerce storefront, ensuring that pricing rules and product data flow consistently to protect fulfilment accuracy. By automating the movement of orders and inventory, we help teams remove the manual workarounds that often compromise data integrity during high-volume periods.
Auditing the SAP data structure first
We connect your SAP ECC and BigCommerce systems, supporting ERP and Ecommerce integration for efficient operations. Our consulting services are invaluable, with system audit services that uncover inefficiencies between SAP ECC, BigCommerce, ERP, and Ecommerce platforms. These audits empower our consultants and your team to take decisive action, ensuring your technology ecosystem runs smoothly and efficiently. This enables you to deliver a consistently excellent experience to your customers, keeping your business competitive and responsive to changing demands.
Solution Design
Integrating SAP ECC and BigCommerce requires navigating the friction between legacy ERP structures and modern ecommerce APIs. We define SAP ECC as the authoritative source for product data and inventory, while BigCommerce captures storefront orders. A critical design decision involves how to map complex SAP pricing logic into BigCommerce without hitting API rate limits. We typically choose to batch high-volume updates to protect storefront performance, accepting a slight lag in pricing reflects for the sake of system stability. This design ensures your finance team closes month-end using SAP as the source of truth, while the warehouse works from ERP fulfilment records. By sequencing order-to-cash first and deferring non-critical attribute syncs, we maintain operational control during high-volume periods.
Mapping order flows and inventory logic
The integration manages the flow of orders, inventory, and pricing updates between systems. SAP ECC remains the authoritative source for product data and customer-specific discounts, while BigCommerce captures order data. Orders are pushed to the ERP, where they are transformed into Sales Orders for fulfilment. We prioritise data integrity by validating storefront tax and shipping lines before they hit the ERP ledger, preventing reconciliation gaps at month-end. Monitoring is embedded to catch failed transmissions or API timeouts early, ensuring that inventory levels on the storefront reflect the actual available-to-sell stock held in the ERP.
Ensuring secure orchestration and data compliance
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between SAP ECC and BigCommerce, connecting ERP and Ecommerce systems. IPaaS simplifies data exchange, reduces manual effort, and supports real-time operations for both SAP ECC and BigCommerce. This approach ensures ERP and Ecommerce data integrity, scalability, and compliance, while robust security standards protect sensitive information throughout the integration process.
Surfacing data exceptions and reconciliation gaps
Standard dashboards often miss the quiet failures that compound into major financial discrepancies. Visibility means detecting when an order is captured on the storefront but fails to create a corresponding record in the ERP due to a pricing mismatch or missing data. We monitor for these orphaned records and processing errors as they occur. Instead of just showing general status, we surface data-level exceptions that require intervention, such as inventory sync delays or tax calculation drifts. This ensures your team can fix the root cause before the warehouse identifies a pick failure or finance spots a reconciliation gap.
Building operational ownership across your teams
Handover focuses on operational ownership for finance, ecommerce, and operations teams. We provide the specific operating model for your SAP ECC and BigCommerce setup, documenting where material masters, price lists, and order statuses live. Training ensures your team knows how to reconcile daily totals against ERP records, while ecommerce managers learn to monitor stock levels to prevent overselling. We provide operational documentation rather than technical archives, written for the people running the business. This ensures your team can identify exception types and respond to alerts from the integration layer. Our goal is a clear transition where each team understands their role in maintaining data integrity across the stack.
Maintaining long-term data integrity post-launch
Support is an operational partnership focused on protecting the flow of order and inventory data between SAP and BigCommerce. We monitor for API timeouts and data processing failures that could stall fulfilment or lead to pricing discrepancies on the storefront.
When complex issues arise, such as pricing logic mismatches or financial reconciliation gaps, we provide technical escalation to resolve the root cause. This oversight ensures that your finance and ecommerce teams do not spend their days manually correcting data. We maintain visibility across the integration layer to ensure that SAP ECC remains the reliable source of truth for your B2B and B2C operations.
Common failures
Complex B2B price synchronisation failure.
Operational impact: SAP's customer-specific pricing, using complex condition records, fails to map correctly to BigCommerce price lists. This shows incorrect prices to B2B buyers, erodes trust, and creates intense manual work for sales and CX teams who must correct every affected Sales Order. The finance team is left to manually issue credit notes and re-invoice, creating significant operational drag.
Prevention / Action: The integration must be designed to translate SAP's pricing procedures into BigCommerce price lists reliably. This typically involves scheduling bulk updates outside of peak hours and using a middleware queue to manage API rate limits. Logic should be built to handle different pricing conditions from SAP, correctly assigning customers to their specific price list in BigCommerce.
Inventory latency and overselling.
Operational impact: Stock level updates from SAP ECC lag, so the Available-to-Promise (ATP) quantity in SAP is not accurately reflected in BigCommerce. This results in overselling, forcing the CX team to cancel orders and line items, which damages customer trust. Fulfilment teams see orders they cannot dispatch, and the finance team is burdened with processing the resulting refunds.
Prevention / Action: Design the integration to sync the definitive SAP ATP quantity, not just a raw warehouse stock figure, using inventory-specific IDocs on a frequent, defined schedule. The integration logic should include an option for a stock buffer (e.g. holding back a small number of units) to mitigate timing issues. Establish SAP as the single source of truth for all inventory figures.
SKU and product data mismatch.
Operational impact: SAP ECC often uses fixed-length, padded SKUs (e.g. '000012345') which are not native to BigCommerce. If the integration does not correctly strip or pad the SKU during data syncs, inventory updates fail to match the right product, and new orders transmitted to SAP are rejected as the item number is not recognised. This leads to manual data cleansing by merchandising teams and manual order entry by the sales operations team.
Prevention / Action: Define a strict rule for SKU formatting within the integration layer that accounts for SAP's conventions. The middleware must consistently transform the SKU on all relevant data flows, for example by trimming leading zeroes from SAP's material master IDoc (MATMAS) before updating BigCommerce. When creating Sales Orders in SAP from BigCommerce orders, the process must reverse this, padding the SKU to match SAP's expected format.
Failed or delayed dispatch notifications.
Operational impact: A Post Goods Issue (PGI) in SAP fails to trigger a corresponding shipment confirmation in BigCommerce. This means customers do not receive tracking information, leading to a high volume of 'Where is my order?' queries for the customer service team. For B2B accounts, this also delays invoicing and negatively impacts the reliability of the service.
Prevention / Action: The integration must be configured to correctly process outbound delivery IDocs (e.g. DESADV) from SAP and use them to trigger a shipment creation in BigCommerce, including the tracking number. This flow should include exception handling to monitor for failures, with alerts for the operations team. The logic must also accommodate partial shipments, creating separate fulfilment records in BigCommerce for each dispatch from SAP.
Frequently asked questions
Our SAP ECC instance uses custom IDoc segments. Will this prevent integration with BigCommerce?
Not necessarily, but it requires careful mapping. Standard integrations often fail because they only account for default SAP IDoc structures, so custom fields for pricing or customer data are ignored. A properly designed integration uses a middleware layer to transform data from your specific IDoc segments, ensuring a custom discount field from SAP is correctly applied to a BigCommerce price list.
How do we manage complex, customer-specific B2B pricing from SAP in BigCommerce?
SAP ECC must remain the source of truth for pricing to maintain accuracy. The integration's role is to synchronise these complex pricing rules and customer-specific discounts into BigCommerce's Price Lists, which are then associated with the correct customer records. This ensures that B2B buyers see their negotiated pricing on the storefront, preventing incorrect order values that require manual correction.
What is a common failure point when syncing product data from SAP to BigCommerce?
A frequent failure occurs when SAP ECC sends a padded SKU, such as '000012345', but BigCommerce stores the SKU as '12345'. This mismatch breaks the product link, causing inventory level updates sent from SAP to fail. The operational consequence is that inventory counts become inaccurate on BigCommerce, leading to overselling or showing items as out of stock when they are not.
We process hundreds of B2B orders manually. How does an integration practically solve this?
Manual order entry from BigCommerce into SAP is slow and introduces fulfilment errors. An automated order-to-cash process posts each new BigCommerce order directly into SAP ECC as a Sales Order, typically triggered on successful payment. This eliminates keying errors and can cut the time from order placement to warehouse processing from hours to minutes.
How are returns and credit notes handled between BigCommerce and SAP?
This process is a common source of financial discrepancy if not connected properly. A robust integration ensures that a refund issued in BigCommerce automatically triggers the creation of a corresponding Credit Memo in SAP ECC. Without this, the finance team must manually reconcile refunds against sales figures, which complicates the month-end close process.
