CommerceWeave + SAP Business One: SAP Business One connected to B2B commerce — ERP-accurate pricing, inventory, and order management for SAP SMB customers.
CommerceWeave's SAP Business One native integration connects the large mid-market and SMB segment running SAP B1 to B2B commerce with ERP-accurate pricing from SAP's price list framework, warehouse-level inventory, and sales order creation through the SAP B1 Service Layer API.

What This Integration Enables
SAP B1 Price List Resolution with Special Pricing Agreements
SAP Business One organizes pricing through price lists assigned to business partner groups, with customer-specific prices and special pricing agreements overriding the group price list for individual customers or customer-item combinations. CommerceWeave queries the SAP B1 pricing engine via the Service Layer API, receiving the effective price for the authenticated buyer, the specific item, and the quantity requested. Special pricing agreements — which are time-bounded price commitments for specific items — are included in the resolution. The integration handles the SAP B1 price hierarchy correctly, ensuring that special pricing agreement prices take precedence over customer-specific prices, which take precedence over price list prices.
Multi-Warehouse Inventory for SAP B1 Deployments
SAP Business One supports multiple warehouses within a single company database, and CommerceWeave's inventory integration queries warehouse-specific availability. Each buyer account can be configured to display inventory from one or more designated warehouses. For SAP B1 distributors with a primary warehouse and satellite locations, the integration presents availability from the relevant warehouse set and creates sales orders with the appropriate warehouse assignment in SAP B1.
SAP B1 Service Layer API Order Creation
CommerceWeave creates sales orders in SAP B1 through the Service Layer REST API — SAP's standard integration interface for B1 — ensuring compatibility with SAP's standard upgrade path. The order creation call includes all required SAP B1 document fields: customer code, document date, delivery date, line items with warehouse assignment, pricing, and document-level comments. The SAP B1 document number is returned and displayed in the CommerceWeave portal. A/R invoice and delivery note data is pulled from SAP B1 in real time for display in the buyer's order history.
Common Edge Cases & Special Handling
AI Copilot for SAP Integration
The AI copilot analyzes SAP B1's item master, price list hierarchy, special pricing agreement data, and business partner structure to generate CommerceWeave entity mapping proposals. It validates price resolution by testing a sample of customers across all price list assignments and special pricing agreements, comparing CommerceWeave-resolved prices against SAP B1 expected values.
Mapping Generation
AI Copilot reads your ERP schema and auto-generates field mapping configurations, reducing manual mapping time by up to 80%.
Test Data
Generates realistic synthetic test datasets that mirror your ERP data structure so you can validate the integration before go-live.
Validation
Runs automated validation passes against your field mappings and flags edge cases — null values, data type mismatches, and format inconsistencies.
Monitoring
Post-launch monitoring surface that surfaces sync errors, latency anomalies, and field-level data quality issues in real time.
