Already Have ERP/CRM Systems? How to Integrate AI Capabilities at Minimal Cost?

Many enterprises already have mature ERP, CRM, OA, and other systems and don’t need a complete overhaul. We help embed AI capabilities into your existing IT architecture — CRM customer service sidebar, OA approval assistant, ERP smart data entry, WeCom/Feishu bots — achieving minimal transformation cost and maximum AI value. Gartner predicts that by 2026, over 80% of enterprises will use generative AI in production environments, making "lightweight embedding" the mainstream approach for enterprise AI adoption.

> The Lenovo-IDC joint report "Global CIO Report" shows that global enterprise AI spending in 2025 will be nearly triple that of 2024, but 37% of enterprises are skeptical about AI’s value, with low-quality data, unclear ROI, and compliance risks as the top three obstacles. The core value of large model integration is to validate AI’s ROI with minimal investment.

Core Capabilities of Large Model Integration

  • Public Large Model API Connection: Full coverage of mainstream models like Tongyi, DeepSeek, GPT, Baichuan, etc.
  • Lightweight AI Transformation of Legacy Systems: Embed AI via sidebars/dialog boxes without system overhaul.
  • Unified Multi-Model Orchestration Layer: Intelligent routing by scenario, cost controllable.
  • API Gateway & Traffic Control: Call quotas, rate limiting, cost alerts.
  • Compatible with Existing Permissions: Seamless RBAC policy integration, zero data security risk.
  • Six Typical Integration Scenarios

    AI Customer Service Sidebar Embedded in CRM

    Sales staff get real-time script suggestions, customer profile analysis, and competitive comparison data via the sidebar in the CRM interface. No system switching needed, boosting sales efficiency by over 30%.

    AI Approval Assistant Integrated into OA

    Contracts and expense reports are automatically pre-reviewed — AI identifies abnormal clauses, amount deviations, and compliance risks, flagging them before routing to approvers. Approval efficiency increases by 50%, and omission risk decreases by 60%.

    Smart Data Entry in ERP

    Data from emails, images, and PDFs is automatically recognized and filled into ERP forms, with manual review only required. Data entry efficiency increases by 80%, error rate reduced by 90%.

    WeCom/Feishu Bots

    Employees query data in WeCom/Feishu using natural language — "What are the sales figures for East China this month?" The bot returns charts and analytical conclusions in seconds.

    AI Q&A Embedded in Corporate Website

    24/7 AI customer service handles product inquiries, technical support, and after-sales issues, reducing customer wait time from 5 minutes to 2 seconds and boosting resolution rate to 85%.

    AI Review Embedded in DingTalk Approval Flows

    Procurement and reimbursement approvals are automatically pre-reviewed — AI compares historical data, verifies amount reasonableness, and flags anomalies, shortening approval cycles by 60%.

    Key Challenges and Solutions for Enterprise AI Integration

    > McKinsey’s 2025 report notes: 88% of surveyed organizations are using AI, but most are still in the pilot stage, with scaling from pilot to production being the core challenge. Large model integration is the ideal entry point to address this — embedding AI into existing systems so employees use it naturally in daily work, without learning new tools.

    Three core concerns and corresponding solutions:

    ConcernSolution
    Data SecurityAPI gateway data desensitization + optional private deployment
    Cost OverrunMulti-model intelligent routing + call quota control
    System Modification RiskPlug-in embedding, zero intrusion into existing business logic

    FAQ

    Does Large Model Integration Require Modifying Existing Systems?

    No system overhaul is needed. We embed AI capabilities into existing system sidebars or dialog boxes via API gateway + plug-in approach, fully preserving original business logic and permission systems. Gartner predicts over 80% of enterprises will use generative AI by 2026; "lightweight embedding" rather than "rip and replace" is the best path for enterprise AI adoption.

    How to Control the Cost of Multi-Model API Calls?

    We deploy a unified orchestration layer that intelligently routes based on task complexity: simple Q&A routed to low-cost models (e.g., DeepSeek-V3), complex reasoning to high-capability models (e.g., GPT-4o), along with API call quotas, rate limiting, and cost alerts. Enterprises can precisely control monthly AI spending and avoid cost overruns.

    How Is Data Security Ensured After Integrating Large Models?

    We use a three-tier security mechanism: transport layer TLS encryption, API gateway data desensitization (automatically identifying and masking sensitive information such as ID numbers and bank cards), and permission systems compatible with existing RBAC policies. A joint report by Lenovo and IDC shows 37% of enterprises are skeptical about AI value, with data security as the top concern — our solution ensures enterprise data never resides with the large model provider.
