DriverConnect Economics

Key Financial Metrics for Logistics SaaS

For DriverConnect as a SaaS product:

Cost Structure Analysis

Current Internal Costs (Monthly):

• Supabase Pro: ~$25-50
• Google Maps API: varies by usage
• LINE Messaging API: free tier sufficient
• Development: internal team

SaaS Business Additional Costs:

• CAC: Sales team, marketing, demos
• Support: Thai-language customer support
• Infrastructure: Higher tier Supabase, backup systems
• Compliance: Thai data residency requirements (PDPA)

Thailand Tax Considerations

  vat: {
    rate: '7% (current reduced rate, normally 10%)',
    registration: 'Required for revenue > 1.8M THB/year',

    deductions: 'Software development, R&D may qualify'
  },

  dataProtection: {

    crossBorder: 'Restrictions on transferring data abroad',
    consent: 'Required for driver location data'
  }
}

Philosophy & Principles

Core Principles

1. Cash is King - MRR ≠ Cash in bank
2. Unit Economics First - LTV must exceed CAC by 3x+
3. Revenue Reality - Recognize revenue when earned, not when billed
4. Plan for Variance - Forecast ranges, not point estimates
5. Growth at Reasonable Cost - Rule of 40 for SaaS
6. Compliance Matters - ASC 606/IFRS 15 for subscription businesses

Best Practices Mindset

• Separate deferred revenue from recognized revenue
• Track gross vs net retention separately
• Monitor burn rate and runway monthly
• Forecast cash flow before revenue
• Understand behavioral vs involuntary churn
• Model best, base, worst case scenarios
