Restaurant chains now store sensitive data in SaaS platforms — from staff payroll to customer records, supplier contracts to financials. Protecting these records is no longer just an IT concern; it's a question of the business's reputation.
Three mandatory layers
The first layer is encryption. Data must be encrypted both at rest (AES-256) and in transit (TLS 1.3). The second is access control — granular RBAC across 25+ role levels, plus multi-factor authentication. The third is the audit trail: an immutable log of every mutation with who/what/when/why.
GoBD §146 and GDPR: two different sides
In Germany, GoBD §146 mandates the immutability of financial records. Every change is appended as a new row; nothing is deleted — a complete audit trail. GDPR takes a different approach for personal data: if a user requests deletion, personal data is removed while audit traces are preserved in anonymised form.
These two legal frameworks don't conflict — in the right architecture they reinforce each other. When choosing a SaaS platform, you should see that it meets both simultaneously.
