Accounting Micro Systems is a long-established San Francisco-based business software firm and SAP partner founded in 1988. The company positions itself as a leading partner for SAP and Sage software in Northern California, helping small and mid-sized businesses select, implement, and run accounting and ERP systems suited to their operations. Within the SAP portfolio, Accounting Micro Systems specialises in SAP Business ByDesign and SAP Business One, the two primary SAP offerings for small and mid-sized companies. As a business partner, the firm provides software selection consulting, implementation, training, custom development, upgrade services, application management, and continuous technical support. Its customer base spans more than 400 organisations, making it one of the larger and more comprehensive SAP Business One and Business ByDesign consultancies in Northern California by stated customer count. To support integration scenarios between SAP and surrounding systems, Accounting Micro Systems partners with Dell Boomi as a Boomi Managed Services partner, using the Boomi platform exclusively to deliver end-to-end integrations. The firm's positioning emphasizes long-tenured SME experience and a multi-vendor accounting and ERP advisory role, rather than a SAP-pure-play model. SAP partner directories list the company as an SAP Registered Partner with reseller, implementer, and managed services designations. The firm's website at accountingmicro.com is its primary public-facing channel.
