Neuralab公司发布的经验总结指出，"只需连接到ERP"这一在几乎每个电商项目中频繁出现的表述，其中的"只需"二字掩盖了巨大的技术复杂性1。该文章强调，新电商平台构建属于绿地项目，而与现有ERP/CRM系统的集成则是棕地项目，两者不应采用相同的规划方式1。
系统集成的核心难点在于时序矛盾与所有权模糊。支付授权必须同步进行，使客户在结账屏幕上实时等待，但之后的订单创建、库存预留等操作必须异步处理以维持转化率1。这种架构差异可能导致严重后果：付款可能在订单实际创建前就已被授权，若缺乏明确的架构设计，将造成资金已扣款但订单丢失的问题1。
遗留ERP系统经过多年运行，积累了大量文档未记录的"怪异行为"，如字段截断、手动定时任务等隐藏复杂性1。Neuralab建议的解决流程是：先构建新系统，再审计遗留系统，最后设计集成，而非将两者合并为单一项目范围1。该方案还提议引入显式的编排层（如n8n、Kafka等消息平台），为系统交接点提供独立的日志和重试机制1。
Neuralab has published guidance on eCommerce platform development, identifying a common pitfall in integrating existing ERP systems with new digital storefronts.1 The phrase "just connect it to our ERP" appears in nearly every eCommerce project, yet the word "just" obscures substantial technical complexity.1 The fundamental challenge lies in distinguishing between two different engineering problems: building a new storefront as a greenfield project versus integrating it with legacy systems as a brownfield project, which should not be planned using the same approach.1
The technical obstacles extend beyond straightforward data synchronization.1 Payment authorization must occur synchronously, as customers wait on the checkout screen, but subsequent operations—including order creation and inventory reservation—require asynchronous processing to maintain conversion rates.1 This timing mismatch creates a critical vulnerability: payments can be authorized before an order is actually created in the system, and without explicit architectural design, this leads to scenarios where funds are collected but orders are lost.1 Additionally, legacy ERP systems accumulate undocumented "quirky behaviors" accumulated over years of operation, such as field truncation and manual cron tasks that are not recorded in official documentation.1
Neuralab recommends a phased approach: construct the new system first, then audit the legacy system, and finally design the integration—rather than combining both into a single scope.1 The proposed solutions include introducing an explicit orchestration layer, such as n8n or Kafka-based messaging platforms, to provide independent logging and retry mechanisms at the handoff points between systems.1
