GDPR for small businesses: what actually applies to you

You don't need a Brussels law firm to be defensibly GDPR-compliant. The obligations that genuinely apply to small companies, minus the mythology.

GDPR anxiety scales inversely with company size: the smallest teams often assume they need enterprise-grade privacy programs, then do nothing because that feels impossible. The truth is more manageable. GDPR applies to you if you process personal data of people in the EU — but what it demands of a 15-person SaaS is not what it demands of a bank.

The obligations that genuinely apply

  • A lawful basis for each processing purpose — for most small B2B companies that's contract performance and legitimate interest, with consent reserved for marketing.
  • A privacy notice that honestly describes what you collect and why, in language a customer can read.
  • A record of processing activities — for a small company, a well-kept spreadsheet is legitimate.
  • The ability to answer data subject requests (access, deletion, portability) within a month.
  • Data processing agreements with the vendors that touch personal data for you.
  • Breach awareness: know what qualifies, and be able to notify your supervisory authority within 72 hours.

What you probably don't need

Most small businesses don't need a Data Protection Officer — that's triggered by large-scale monitoring or special-category processing, not headcount. You likely don't need consent banners for strictly necessary cookies, and you don't need a 40-page policy no one reads. Regulators consistently reward honest, proportionate programs over paperwork theatre.

A weekend-sized starting plan

  • List every place personal data enters and lives: forms, CRM, analytics, support desk, payroll.
  • Write the processing record from that list and assign each purpose a lawful basis.
  • Fix the leaks the list exposes — the analytics tool nobody uses, the export sitting in someone's downloads folder.
  • Collect signed DPAs from your processors; the major platforms all have them ready.
  • Draft the breach playbook: who decides, who notifies, within what window.

Proportionate, documented and honest beats elaborate and abandoned — and it's within reach of any team that can spare a focused week.
