Custom Development ROI Example

// 5-Year Total Cost of Ownership Analysis

const customSoftware = {
  year1: {
    development: 150000,
    infrastructure: 5000,
    maintenance: 0,
    total: 155000
  },
  years2to5: {
    maintenance: 25000,  // 15-20% of dev cost
    infrastructure: 6000,
    enhancements: 20000,
    annualTotal: 51000
  },
  fiveYearTotal: 155000 + (51000 * 4), // $359,000
  
  benefits: {
    perfectFit: true,
    ownership: true,
    noPerUserFees: true,
    unlimitedUsers: true
  }
};

const saasAlternative = {
  monthlyPerUser: 150,
  users: 50,
  monthlyTotal: 7500,
  annualTotal: 90000,
  fiveYearTotal: 450000,
  
  limitations: {
    fitToNeeds: '70%',
    customization: 'Limited',

  }
};
