SAP Business One. SAP Business One is an enterprise resource planning (ERP) application designed for small and medium-sized enterprises, and marketed by the German company SAP SE. As a company, SAP Business One focuses on automating key business functions in finance, operations, and human resources.

History 
SAP Business One was initially launched in Israel in 1996 under the name "Menahel" ("manager") or "TopManage", for other countries. The company was founded by Reuven Agassi (CEO). The product was designed by Shai Agassi and the development team was led by Hilla Mazinter. At a later stage the product was split out into a separate company that Reuven Agassi was running as CEO with Gadi Shamia was VP Sales

In its first years, TopManage was sold in the Israeli market only and was the first Windows/Mac business management product to be offered in the Israeli market. In 2000, TopManage started its global expansion into markets in Europe and Latin America.

In March 2002, SAP acquired the financial systems of "TopManage" and subsequently rebranded the system as SAP Business One. Reuven Agassi and Gadi Shamia, founders of TopManage, assumed executive positions at SAP as part of the acquisition. Notably, a year before this, SAP had also acquired "TopTier," a sister company of TopManage. Shai Agassi, the son of Reuven Agassi, was the founder of TopTier. 

The acquisition allowed SAP to reach out to the small market through its partners and also to gain additional business from the smaller subsidiaries of its enterprise customers.

 Mobile and Web Access, SAP Business One also supports mobile deployment and web access, facilitating real-time management of core business operations from anywhere.
Each module handles specific business tasks on its own, but is linked with other modules where applicable. For instance, an invoice from the billing transaction in Sales & Distribution would pass through to accounting, where it will appear in accounts receivable and cost of goods sold.

Architecture 
SAP Business One is a typical Client–server model software product.

Client software is primarily the SAP Business One client that is a Microsoft Windows-based product that connects to a back-end server. SAP also offers clients for phones and tablets (iOS and Android) that contain a subset of the full features aimed at sales employees.
Server software is run on either a Microsoft SQL Server database (Windows) or SAP HANA database (Linux).

Partners and community 
SAP Business One is delivered through its global partner network (SAP PartnerEdge) consisting of the following partner types:

 Value-Added Resellers (VAR) is an SAP partner that sells, implements and supports the product to end customers.
 Software Solution Partners (SSP) is an SAP partner that creates horizontal or vertical standard solutions on top of the SAP Business One platform with the SAP Business One SDK and sells them via the VAR partners.
 Open Ecosystem Once you join you will be able to sell, service, and market SAP-approved products available through its distributor channel. It's free and easy to join, with only a small amount of required training to complete before you begin.

Extensibility 
Custom development (called add-ons) are done using the SAP Business One SDK. It is COM-based development done in Microsoft Visual Studio with C# or VB.NET.

SAP Business One SDK consists of:
 Data Interface API (DI-API), where you can create new business object around the normal SAP Business One client but still adhere to the core business rules
 User interface API (UI-API), where you can modify existing SAP Business One client screens, create new screens and change/block the normal event flow
 SAP Business One Integration Technology (B1i), where you can visually create Business flows using XML/XSLT
 Service Layer for SAP HANA, where you can, using OData, create business objects
Service Layer for Microsoft SQL Server, where you can, using OData, create business objects
