SGA provides independent audit services to companies, the Government of Namibia, individuals and any other legal entity or organisation within Namibia. SGA is geared to comply with International Standards of Auditing.

SGA follows the Probe auditing methodology (based on International Standards of Auditing). Probe is applied through the Caseware computer tool that includes electronic working papers.

This allows auditors to prepare  audit schedules, planning documents, working papers, reviews and to compose risk assessments.

Caseware Probe allows for a technology-based audit that provides workflow support that is easier, more focused and efficient.

Caseware is also an interactive application that incorporates the latest industry-specific guidance. The majority of financial statements are drafted through Caseview, an application that links up with Caseware.
