I need a developer who can connect my eCommerce store to SAP Business One through the official API so that stock levels and order details move automatically between the two systems. The focus is on two-way, near-real-time synchronisation of: • Inventory updates (SKU, quantity, warehouse) • Order processing data (new sales, status changes, fulfilment info) The goal is to eliminate manual CSV uploads and give our team live visibility inside SAP B1 while keeping the web shop accurate for customers. You are free to choose the most efficient approach—Service Layer REST endpoints, DI API, webhooks or a middleware layer—as long as it is robust, well-documented and can handle our current daily volume of roughly a thousand SKUs and several hundred orders. Deliverables • Source code or integration package with clear configuration instructions • Mapping documentation for all synced fields • A short hand-off session (screen-share or recorded) showing deployment and basic troubleshooting • Success criteria: inventory and orders sync in both directions without errors during a full business-day test window If you have prior SAP B1 API work—especially tying into popular eCommerce platforms—please mention it along with your estimated timeline and cost Further Ad Hoc work will be required, depending on performance.

Hi I can build a robust two way integration between your eCommerce platform and SAP Business One using the official API stack, ensuring near real time synchronization of inventory and order data. I have experience working with ERP integrations and REST based middleware solutions designed for reliability, logging, and long term maintainability. For this project, I would typically use the SAP B1 Service Layer REST endpoints for modern, scalable communication, combined with secure webhook or scheduled sync logic depending on your store capabilities. Inventory updates will sync SKU, quantity, and warehouse data in both directions, while order processing will push new sales into SAP B1 and reflect status changes and fulfillment updates back to the web shop. The architecture will include structured error handling, retry logic, and logging to ensure stability under your volume of one thousand SKUs and several hundred daily orders. You will receive clean source code or a deployable integration package, full field mapping documentation, and a recorded hand off session covering deployment and troubleshooting. The final validation will include a monitored full business day test to confirm accurate two way synchronization without data loss. I am also open to ongoing optimization and support as your volume grows. Best, Justin

Hi I can build a robust two-way integration between your eCommerce store and SAP Business One using the most efficient mix of Service Layer REST endpoints, DI API, and webhooks to keep inventory and order data synced in near real time. The core technical challenge is ensuring bidirectional accuracy across ~1,000 SKUs and hundreds of daily orders, and I solve this through structured field mapping, queued sync operations, and clear retry/error-handling logic. I’ll implement automated stock updates, order creation, status flows, and fulfilment syncing so both systems stay perfectly aligned without manual imports. The integration package will come with clean configuration instructions, full field-mapping docs, and a walkthrough so your team can deploy and troubleshoot independently. My experience with SAP B1 APIs and eCommerce platforms ensures the solution is stable, scalable, and ready for long-term expansion. Thanks, Hercules

Hey, I will build the two-way sync between your eCommerce store and SAP Business One, covering real-time inventory updates (SKU, quantity, warehouse) and order processing (new sales, status changes, fulfilment) so your team gets live visibility in SAP while the web shop stays accurate for customers. For the sync architecture, I will use the SAP B1 Service Layer REST API with a webhook listener on the eCommerce side, plus a reconciliation job that runs every 15 minutes to catch any events the webhooks might miss during downtime. Questions: 1) Which eCommerce platform are you using - Shopify, WooCommerce, Magento, or something custom? 2) Is your SAP B1 instance hosted on-premise or on SAP HANA Cloud? 3) Do you need the sync to handle product master data (descriptions, images), or strictly inventory and orders? Looking forward to discussing further. Best regards, Kamran

I’ve handled several SAP Business One integrations using the Service Layer, specifically focusing on high-volume inventory and order synchronization for enterprise e-commerce platforms. Having navigated the intricacies of SAP B1's DI API and Service Layer schema before, I understand the critical importance of mapping custom UDFs and maintaining strict transactional integrity between your web storefront and the ERP backend. My previous work involved reconciling complex tax structures and multi-warehouse inventory logic, ensuring that the ERP remains the single source of truth without impacting web performance or data consistency. I will utilize the SAP B1 Service Layer (REST API) to architect a secure middleware layer that facilitates bi-directional data flow for item masters, real-time stock levels, and automated sales order creation. My approach focuses on implementing an asynchronous queue-based synchronization system to prevent data loss during peak traffic and setting up granular error logging to catch and retry failed API handshakes automatically. I will optimize OData filters to fetch only delta changes, which minimizes server overhead and ensures your inventory is updated across all channels in near real-time. Furthermore, I'll ensure that the integration respects your specific business logic for price lists and customer-specific discounts during the checkout sync process. To ensure the architecture is optimized for your environment, are you currently running SAP B1 on HANA or SQL Server, as this dictates the best practices for Service Layer performance tuning? Additionally, do you require the sync to handle freight calculations or specific payment gateway reconciliation within the SAP banking module? I’m available for a brief chat to discuss these technical specifications and can provide a structured roadmap once we align on the field-mapping requirements.
