Code sketch

A simplified illustration of the core logic, not production code.

// Commission Calculation Service
@Service
public class CommissionCalculationService {
    
    @Autowired
    private AffiliateRepository affiliateRepository;
    
    @Autowired
    private SalesRepository salesRepository;
    
    public CommissionReport calculateMonthlyCommissions(String month, String year) {
        List<Sale> sales = salesRepository.findByMonthAndYear(month, year);
        Map<String, BigDecimal> commissions = new HashMap<>();
        
        for (Sale sale : sales) {
            Affiliate affiliate = affiliateRepository.findById(sale.getAffiliateId());
            
            BigDecimal commission = calculateCommission(sale, affiliate);
            commissions.merge(affiliate.getId(), commission, BigDecimal::add);
            
            // Track performance metrics
            updateAffiliatePerformance(affiliate, sale, commission);
        }
        
        return new CommissionReport(commissions, sales.size(), 
                                  calculateTotalCommission(commissions));
    }
    
    private BigDecimal calculateCommission(Sale sale, Affiliate affiliate) {
        BigDecimal baseCommission = sale.getAmount()
            .multiply(affiliate.getCommissionRate())
            .divide(new BigDecimal(100));
            
        // Apply tier-based bonuses
        if (affiliate.getCurrentTier().equals("PREMIUM")) {
            baseCommission = baseCommission.multiply(new BigDecimal("1.2"));
        }
        
        return baseCommission;
    }
}
