Cost Reduction Strategies
Save 15-20%
Multi-year audit contract
Lock in a 3-year engagement with your auditor. Most firms offer 15-20% discount for the commitment. This also simplifies year-over-year comparisons since the same team knows your environment.
Save 60-80% of staff time
Automate evidence collection
A GRC platform continuously collects evidence, so your team is not scrambling before the audit. The $10K-$25K/year platform cost pays for itself in reduced staff hours within the first year.
Save 30-40%
Bundle multi-framework audits
If you need both SOC 2 and ISO 27001, doing them together with the same auditor saves 30-40% compared to separate engagements. Control overlap means evidence is reused.
Save 10-15%
Avoid Q4 audit scheduling
October through January is busy season for audit firms. Scheduling in Q2 or Q3 often gets you lower rates and more attention from the audit team.
