Share

Introduction

For startups and SMEs, GDPR compliance can seem like a complex and expensive challenge. This guide offers a practical and prioritized approach to achieving compliance efficiently.

Where to Start

Priority 1: Data Mapping

Before any action, identify:

  • What personal data you collect
  • Where it is stored
  • Who has access
  • What purposes it is used for

Priority 2: Legal Basis

For each processing, define the legal basis:

  • Consent
  • Contract execution
  • Legal obligation
  • Legitimate interests

Priority 3: Basic Documentation

  • Clear privacy policy
  • Terms of use
  • Record of processing activities

Compliance Checklist

  • Cookie consent
  • Forms with consent checkbox
  • Contact email for exercising rights

  • Contracts with subcontractors (processors)
  • Procedure for data subject requests
  • Basic risk assessment

Recommended (Do in 90 days)

  • Team training
  • Data retention policy

Estimated Costs

ItemEstimated Cost
Initial audit€500-2,000
Basic documentation€300-1,000
External DPO (annual)€1,200-3,600
Team training€200-500

Common Mistakes to Avoid

  1. Ignoring GDPR - Fines can reach 4% of turnover
  2. Copying generic policies - They must reflect the company's reality
  3. Forgetting subcontractors - All processors need contracts
  4. Not documenting - Demonstrated accountability is mandatory

When You Need a DPO

DPO appointment is mandatory when:

  • Large-scale processing of sensitive data
  • Systematic monitoring of data subjects
  • Public authority or body

For most startups and SMEs, a DPO is not mandatory but can be useful.

Conclusion

GDPR compliance doesn't have to be complex. With a prioritized and pragmatic approach, startups and SMEs can achieve an adequate level of compliance without compromising excessive resources.
