Why AffixBuild

Engineered for how contractors actually work

Not a generic ERP bent into shape — a system that speaks BOQ, cost codes and certificates from the ground up.

  • Multi-tenant from day one

    Organisation membership is checked by the application and tenant data is protected with PostgreSQL row-level security.

  • Field records with review

    Responsive forms capture daily reports, BOQ progress and private site photos, with explicit review states for authorized roles.

  • Controlled financial workflows

    Cost records and IPC status changes are tenant scoped, role checked and written through audited API paths.

Deployment

A production stack with explicit ownership

AffixBuild is deployed as a dedicated VPS stack. Commercial terms, rollout support and data onboarding are scoped directly for each implementation rather than represented by unverified public prices.

Self-hosted application

Next.js, NestJS and Caddy are packaged with Docker Compose for a VPS deployment you control.

  • HTTPS reverse proxy
  • Guarded release script
  • Health checks

Private data services

PostgreSQL, Redis and S3-compatible object storage run inside the deployment stack without Supabase.

  • Tenant-scoped database access
  • Private site-photo storage
  • Backup and restore scripts

Controlled team access

Organisation membership and role policies govern the records and workflow actions available to each user.

  • API authorization
  • PostgreSQL RLS
  • Audited mutation paths
