Frequently Asked Questions

When does GDPR apply to SaaS companies?

GDPR applies if you process EU residents' personal data, whether you're in the EU or offering services/monitoring behavior of EU individuals. Most global SaaS companies are subject to GDPR.

What's the difference between controller and processor?

Controllers determine purposes and means of processing. Processors act on controller instructions. SaaS companies are typically processors for customer data but controllers for their own customer account data.

How do we handle international data transfers?

Use approved mechanisms: Standard Contractual Clauses (SCCs), adequacy decisions, or Binding Corporate Rules. US companies should also consider the EU-US Data Privacy Framework.

Disclaimer: Compliance costs and timelines are estimates based on market benchmarks (AICPA fee surveys, vendor pricing indices 2025). Actual auditor fees and internal effort will vary based on your specific control environment, system complexity, and auditor selection. Consult with a qualified CPA for a formal statement of work.
