Maintaining SOC 2 Compliance: Annual Costs and Activities Calendar
Year 1 is the most expensive. Year 2 is cheaper, because the build work is done and the renewal audit tests controls that already exist. Year 3 and beyond stabilises. Here is what maintaining SOC 2 involves and what you need to do each quarter.
The activity calendar is how maintenance actually works. The costs beside it are our model, not published rates, and the methodology page sets out how they are built. The renewal audit is quoted per engagement like the first one: no CPA firm publishes a rate card. The platform line is the one you can check, against the prices vendors publish on AWS Marketplace.

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.
