For platforms and accountants
One integration. Compliant output for every client.
SealDoc's multi-tenant API lets accounting firms and platforms add e-invoicing compliance and legal document sealing across their entire client base — without building anything themselves.
How multi-tenant works
One master API key
One integration per platform. Sub-keys per client tenant with isolated audit trails and usage reporting.
White-label output
No SealDoc branding in documents. Your clients see only your platform.
Usage reporting per tenant
See exactly how many documents each client produced and which features they use.
What you get
BYOS
Bring your own S3-compatible storage bucket. Documents go directly to your infrastructure.
On-prem deployment
Docker or Kubernetes. Air-gapped environments supported. Full data sovereignty.
Dedicated database
No shared infrastructure. Your tenant's data never coexists with other tenants.

Keycloak-based. Integrate with your existing identity provider.
XRechnung-DE output
For German federal and large German buyers. Required for public sector B2G.
Custom SLA
Uptime commitments, dedicated support contact, audit export for your own auditors.
An accounting firm with 200 clients integrates SealDoc once. Every outgoing invoice from every client is automatically Factur-X compliant, timestamped, and archived according to the correct retention period for their country. One integration. Zero per-client setup.
