The B2B service model of enterprise mini-programs

B2B Service Model for Enterprise Mini Programs

The B2B service model of enterprise mini programs is becoming a crucial tool in digital transformation. Leveraging the traffic advantages and technical capabilities of the WeChat ecosystem, businesses can efficiently connect upstream and downstream partners, optimize supply chain management, and provide customized industry solutions.

Core Scenarios of the B2B Service Model

Supply Chain Collaboration Management

Enterprise mini programs enable real-time data exchange between suppliers and buyers. For example, a manufacturing company built a supplier portal through a mini program to achieve:

• Real-time order status tracking
• Inventory level visualization
• Online electronic contract signing

// Example: Order status push interface  
wx.request({  
  url: 'https://api.example.com/supply-chain/orders',  
  method: 'POST',  
  data: {  
    orderId: 'SC20230815',  
    status: 'shipped',  
    timestamp: new Date().getTime()  
  },  
  success(res) {  
    console.log('Status update successful', res.data)  
  }  
})  

Wholesale Procurement Platform

Mini programs designed for distributors typically include:

1. Multi-tier pricing system (dynamic pricing based on order volume)
2. Bulk order processing
3. Dedicated account manager support

Key Technical Implementation Solutions

Enterprise Identity Authentication

Adopt WeChat Open Platform’s "Enterprise Entity Verification" + "Employee Identity Binding" dual authentication:

// Employee identity verification process  
wx.login({  
  success(res) {  
    if (res.code) {  
      wx.request({  
        url: 'https://api.example.com/auth/employee',  
        data: { code: res.code, corpId: 'xxxx' },  
        success(authRes) {  
          // Returns employee ID and permission information  
        }  
      })  
    }  
  }  
})  

Data Security Strategies

Special attention is required for B2B scenarios:

• Encrypted API communication (TLS 1.3)
• Sensitive data masking
• Complete operation log retention

Typical Industry Application Cases

Industrial MRO Procurement

A fastener supplier’s mini program implemented the following functional modules:

• Smart product selection system (auto-matching products based on input parameters)
• 3D model preview
• Delivery time calculator

<!-- Example product parameter input component -->  
<view class="spec-selector">  
  <picker mode="selector" range="{{threadTypes}}">  
    <view>Thread type: {{threadTypes[currentThread]}}</view>  
  </picker>  
  <input type="number" placeholder="Enter length (mm)" bindinput="onLengthChange"/>  
</view>  

Medical Supplies Centralized Procurement

Features include:

1. Online verification of qualification documents
2. Cold chain logistics monitoring
3. Expedited order channels for urgent needs

Operational Data Analysis Dimensions

Customer Behavior Tracking

Key metrics recommended for tracking:

• Procurement decision cycle (from browsing to order placement)
• Product comparison frequency
• Contract approval time

// Tracking example  
function trackBehavior(event, payload) {  
  wx.reportAnalytics('b2b_behavior', {  
    event,  
    userId: getApp().globalData.userId,  
    ...payload  
  })  
}  

Sales Funnel Optimization

Analyze conversion rates at each stage:

1. Inquiry → Quotation
2. Quotation → Contract
3. Contract → Payment

ERP System Integration Solutions

Deep Integration Model

Main integration methods include:

• Real-time data synchronization via API gateway
• Webhook-triggered business processes
• Unified management through a data middle platform

// Example ERP inventory query interface  
async function checkInventory(sku) {  
  const res = await wx.cloud.callFunction({  
    name: 'erpIntegration',  
    data: {  
      action: 'queryStock',  
      skuCode: sku  
    }  
  })  
  return res.result.data  
}  

Common Integration Challenges

Special attention required for:

• Master data consistency (product codes/units, etc.)
• Asynchronous processing timeout mechanisms
• Exception state rollback strategies

Customized Development Strategies

Modular Architecture Design

Recommended micro-frontend architecture:

src/  
├── modules/  
│   ├── quotation/    # Quotation module  
│   ├── contract/     # Contract module  
│   └── dashboard/    # Data dashboard  
└── core/             # Core infrastructure  

Configuration Center Implementation

Dynamically load functional modules via JSON configuration:

// config.json  
{  
  "modules": {  
    "bulkOrder": {  
      "enabled": true,  
      "minLevel": "VIP1"  
    },  
    "auction": {  
      "enabled": false  
    }  
  }  
}  

Payment and Settlement Innovations

Enterprise Payment Solutions

Combination of:

• WeChat Pay enterprise transfers to personal accounts
• Direct bank account integration
• Acceptance bill registration

Credit Term Management Features

Typical implementations include:

1. Real-time credit limit calculation
2. Automatic reminders for due dates
3. Multi-level approval workflows

// Credit check middleware  
function checkCreditLimit(orderAmount) {  
  return new Promise((resolve, reject) => {  
    wx.cloud.callFunction({  
      name: 'financeService',  
      data: { action: 'checkCredit', amount: orderAmount }  
    }).then(res => {  
      res.result.approved ? resolve() : reject('Credit limit exceeded')  
    })  
  })  
}
