Cifras Backend Documentation

Welcome. This site is the engineering reference for the Cifras Strawberry backend.

The current focus is the PAC (Proveedor Autorizado de Certificación) integration — the flow that turns an internal invoice into a legally-valid Panamanian electronic invoice authorized by the DGI.

Where to start

• New to PAC? Read PAC → Overview and then Architecture.
• Onboarding a new tenant? Jump to Tenant Onboarding.
• Debugging a stuck document? See Troubleshooting.
• Need to know what an "MFE", "CUFE", or "DV" is? See the Glossary.
