Enterprise Licence & Inventory API
For groups running several establishments, the per-report model becomes administrative overhead. The annual licence removes the per-report fee, exposes the generator over a REST API so your existing HSE or ERP system can produce inventories directly, and can be deployed inside your own network where substance data must not leave the site.
Annual Licence — from €4.900 per year
Priced per establishment band. Includes both integration routes.
- ▪ Unlimited reports and dossiers across every establishment in the licence — no per-report charge, no seat licences.
- ▪ REST inventory API — post your establishment and substance register, receive the stored record identifier and the Seveso III Σ(q/Q) result, then pull the full dossier.
- ▪ On-premise generator — the same validation and document builders packaged to run inside your network, so substance quantities never leave your infrastructure.
- ▪ Metered API keys — issue and revoke per-integration keys; every call is logged with route, status and resulting record.
- ▪ Group-level change registers — year-over-year revision comparison retained across every site in the licence.
- ▪ Named support contact and advance notice when Annex I qualifying quantities or CLP notation change.
Integration Route A — REST Inventory API
POST /api/public/v1/inventory-report — bearer-authenticated, schema-validated.
Requests are validated against exactly the same schemas as the wizard, including CAS and EC check-digit arithmetic. Invalid identifiers return HTTP 422 with the failing field — bad data cannot enter the register through the API either.

Integration Route B — On-Premise Generator
Runs inside your network. No substance data leaves your infrastructure.
| Deployment | Container image, runs on your own host or private cloud |
|---|---|
| Data residency | Substance data and generated dossiers stay on your systems |
| Identity | Connects to your identity provider; roles map to your HSE groups |
| Updates | Versioned releases when Annex I quantities or CLP notation change |
| Licence term | Annual, per establishment band |
On-premise deployment is scoped per group during onboarding — tell us your establishment count and identity provider in the enquiry form and we will confirm the licence band and rollout sequence.

LEGAL NOTICE: CHEMPAC INVENTORY SYSTEM formats operator-provided data into a standardised European hazardous substance inventory layout for informational and internal record-keeping purposes. It does not constitute legal, environmental, or regulatory certification, and it does not file anything on your behalf.
