Planned Features

GoBD-compliant

Audit-proof archiving according to German accounting principles

10+ Years Storage

Automatic retention for the legally required period

Immutability

WORM storage (Write Once Read Many) prevents subsequent changes

Qualified Timestamps

TSP-compliant timestamps for legally secure archiving

Audit Trail

Complete logging of all access and changes

EU Data Centers

Data is stored exclusively in German/EU data centers

Audit-proof Security

WORM storage guarantees that archived documents cannot be modified or deleted - not even by administrators.

Encryption

AES-256 encryption at-rest and TLS 1.3 in-transit. Optional Bring-Your-Own-Key (BYOK) support.

Currently Available

Until the Archive API is available, created invoices are automatically stored for 30 days (Free), 1 year (Starter) or 10 years (Business). See Pricing for details.
