Documentation

Tapayro's engineering documentation lives with the code. These are the documents that describe how the platform actually works — including what has not been verified yet.

Architecture

Layering, provider switches, and how to add a module without breaking the rest.

docs/architecture.md

Payroll engine

The deterministic pipeline, rule sets, the calculation trace, and how to add a country.

docs/payroll-engine.md

Database

Schema, domain-to-table mapping, multi-tenancy and the auth architecture.

docs/database.md

Security

Threat model, tenant isolation, data minimisation and the audit log.

docs/security.md

Industry packs

One engine, many industries: dimensions, worker types and workforce cost.

docs/industry-packs.md

Supabase setup

Connecting a project, and a plain statement of what is and is not verified.

docs/supabase-setup.md

A hosted documentation site is on the roadmap. Until it exists, these documents are in the repository rather than behind a link that would not resolve.
