SAP Business One (commonly abbreviated as SAP B1) is an enterprise resource planning (ERP) software application developed by SAP SE. It is designed for small and medium-sized enterprises (SMEs) to manage accounting, purchasing, inventory, sales, and customer relationships. The system integrates financial, operational, and management functions into a single platform that can be deployed on-premises or in the cloud, running on either SAP HANA or Microsoft SQL Server databases.[1]
SAP Business One originated in Israel in 1996 as a product called Menahel (“Manager”) or TopManage for international markets. It was developed by Reuven Agassi (CEO) with Shai Agassi and a development team led by Hilla Mazinter. In 2002, SAP SE acquired TopManage and rebranded the system as **SAP Business One**, integrating it into SAP’s portfolio to reach the small and midsized business segment. Reuven Agassi and Gadi Shamia, the founders of TopManage, joined SAP following the acquisition.[2]
Product releases
Since its global launch in 2004, SAP Business One has undergone regular updates. Version 10.0 (released 2020) introduced a web client based on SAP Fiori, integration with Microsoft 365, and new project management and analytics features.[3]
Features
SAP Business One consists of multiple functional modules covering typical business processes:
Administration – configuration and settings

The system supports analytics and mobile access via the SAP Business One Mobile App for iOS and Android.[4]
Architecture
SAP Business One follows a client–server model architecture. The client software runs on Windows and connects to either a Microsoft SQL Server or SAP HANA database. Mobile applications for iOS and Android provide a subset of features aimed at sales and field operations.
Integrations and regional presence
SAP Business One integrates with various third-party systems, including ERP extensions, payment services, and marketplace connectors. Regional implementers in Latin America have developed local tax and compliance adaptations.[5] In the Latin American market, independent developers such as CommerceUp by SourcingUp, based in Buenos Aires, offer B2B e-commerce and marketplace integrations that connect directly with SAP Business One for wholesale operations.[6]

Custom extensions for SAP Business One are developed using the SAP Business One SDK, which includes:
Data Interface API (DI-API) – for creating business objects compliant with SAP logic
User Interface API (UI-API) – for modifying or extending the graphical client
Integration Framework (B1i) – for XML/XSLT-based business flows
Service Layer (OData) – for RESTful API access on HANA and SQL Server versions[7]
