Why Choose Us

Built Exclusively for Papua New Guinea

Unlike generic accounting tools, PNG Tax is designed from the ground up for PNG's unique tax system and business requirements.

Built in PNG, for PNG

Not a generic global tool translated for PNG — purpose-built for PNG tax law, IRC regulations, Nasfund/Nambawan Super, and local business practices by teams on the ground in Port Moresby.

3-Tier Daily Backups

Every day we take three independent backups: local full snapshot, encrypted local DB dump (AES-256 + PBKDF2), and offsite encrypted bundle to Wasabi Singapore — 30-day retention. Competitors give you one.

Enterprise-Grade Security

256-bit TLS, bcrypt-12 password hashing, optional 2FA for admins, role-based access control, full tamper-proof audit trail, CSP + rate-limit + bot-block. Every action is logged and queryable.

Multi-Firm, Multi-Company

Manage many client companies under one tax firm — ideal for accounting practices. Switch between companies with one click, or roll up all companies into firm-wide dashboards.

Bilingual: English + Korean

Every screen in English with one-click Korean toggle. Built-in contextual HelpSystem with 39+ guided walkthroughs in both languages — perfect for PNG's Korean business community.

Always-On Reliability

99.9% uptime target, auto-renewing Let's Encrypt SSL, PM2 watchdog, PostgreSQL 16 with nightly VACUUM, Redis cache, rate-limit + DDoS protection. Your data is always available.

Enterprise Reliability

More Stable Than The Alternatives

GENERIC ACCOUNTING TOOLS

What you often get elsewhere

  • Single daily cloud snapshot — restore window limited, offsite often extra cost
  • GST/income tax modules designed for AU/NZ/SG then localised — edge cases missed
  • English only, or machine-translated Korean pages
  • Basic change log — often just timestamps, no rich before/after diff
  • 2FA only on higher tiers, limited role granularity
  • Overseas support, English only, timezone mismatch
  • Self-service data export often incomplete; deletion requires ticket
