OSAS discontinued

OSAS Accounting and Business Software (Enterprise Resource Planning - ERP), now from Aptean (acquired November 2020) is a business accounting software suite for small- to medium-sized businesses from Open Systems, Inc, which is similar to their Traverse product, but can be deployed across platforms (Linux, Mac OS X, and WIndows as well). OSAS can be hosted on-premises or in the cloud, or in a hybrid fashion.

OSAS has general accounting features (e.g. a general ledger) and analytics for budgeting and expense management, multiple users with access control, and it contains sales and inventory management features. It is customizable, with custom fields, forms, and functions. Its full breadth provides business intelligence functionality and a CRM if these should be desired, and the software is mobile-accessible. Given the many ways in which OSAS can be implemented its cost will vary.
