Architecture

Web dashboard: How it worksTypeScript from the database schema through the API to the front end.

Data: How it worksPostgreSQL. Multi-tenant: every database query is scoped to your team.

Workflow engine: How it worksEvent-driven execution with automatic retries. A failed run resumes where it stopped.

Modules: How it worksDeliveries, drivers, vehicles and the rest are self-contained modules, each with its own routes and components.

Driver app: How it worksAndroid today, with iOS coming soon from the same codebase. Deliveries are cached on the phone and sync on reconnect.

Mobile API: How it worksA dedicated REST API for the driver app, with small payloads and single-purpose endpoints.

Hosting: How it worksServerless deployment that scales with demand. Hosting, monitoring and updates are managed by Tapnet in every tier.

Component	How it works
Web dashboard	TypeScript from the database schema through the API to the front end.
Data	PostgreSQL. Multi-tenant: every database query is scoped to your team.
Workflow engine	Event-driven execution with automatic retries. A failed run resumes where it stopped.

Security controls

Sign-in: DetailSession-based authentication with email and password or OAuth, on the web dashboard and the driver app.

Access control: DetailRole-based permissions: Owner, Admin, Editor, Viewer and Member.

Tenant isolation: DetailEvery database query is scoped to your team, so your data never mixes with another operator’s.

Credentials: DetailStored encrypted in the database. On phones, auth tokens are held in the device’s secure storage, never as plain text.

Transport: DetailEvery API call runs over HTTPS.

Security headers: DetailCSP, X-Frame-Options, XSS protection and HSTS.

Audit trail: DetailEvery user action, workflow run and API key use is logged.

Driver data: DetailDrivers see only their own deliveries, routes and vehicle. Location is tracked only during shifts.

Driver app

Platforms: DetailAndroid, built with Expo. iOS is coming soon from the same codebase.

Distribution: DetailGoogle Play, or an APK for direct enterprise distribution. Apple App Store coming soon.

Updates: DetailFixes are pushed over the air, without waiting for app-store review.

Offline: DetailDeliveries are cached on the phone. PODs are captured without signal and synced on reconnect.

Permissions: DetailCamera, location and storage are requested only when a feature needs them.

Backend: DetailThe same platform as the web dashboard: one source of truth.

POPIA and data handling

Tapnet is built to align with POPIA. Signed PODs are stored with a timestamp and audit trail, with SARS, CIPC and AARTO requirements in mind.

The data protection, data retention, security and breach response policies are published under Legal & POPIA. Questions about operator agreements or data handling go to wynand@tapnet.co.za.
