发票管理系统哪个好?2025最新评测

// 发票管理系统API集成示例
public class InvoiceIntegrationService
{
    private readonly IInvoiceApiClient _apiClient;
    
    public InvoiceIntegrationService(IInvoiceApiClient apiClient)
    {
        _apiClient = apiClient;
    }
    
    // 同步发票数据到ERP系统
    public async Task SyncInvoiceToERPAsync(Invoice invoice)
    {
        try
        {
            var result = await _apiClient.PostAsync("/erp/invoices", invoice);
            if (result.IsSuccess)
            {
                invoice.SyncStatus = SyncStatus.Completed;
                await _invoiceRepository.UpdateAsync(invoice);
            }
        }
        catch (Exception ex)
        {
            // 记录同步失败日志
            _logger.LogError(ex, "发票同步到ERP失败");
        }
    }
}

// 发票数据验证函数示例
class InvoiceValidator {
  constructor() {
    this.rules = {
      taxNumber: /^[A-Z0-9]{15}$|^[A-Z0-9]{18}$/,
      amount: /^\d+(\.\d{1,2})?$/,
      date: /^\d{4}-\d{2}-\d{2}$/
    };
  }

  // 验证发票基本信息
  validateBasicInfo(invoice) {
    const errors = [];
    
    if (!this.rules.taxNumber.test(invoice.taxNumber)) {
      errors.push('纳税人识别号格式错误');
    }
    
    if (!this.rules.amount.test(invoice.amount)) {
      errors.push('金额格式错误');
    }
    
    if (!this.rules.date.test(invoice.issueDate)) {
      errors.push('开票日期格式错误');
    }
    
    return errors;
  }
  
  // 验证发票合规性
  validateCompliance(invoice) {
    // 实现具体的合规性检查逻辑
    return this.checkTaxRules(invoice) && 
           this.checkBusinessRules(invoice);
  }
