How It Works:

This workflow automates the complete retail sales, billing, inventory management, and reporting process using n8n, Google Sheets, and Twilio. It operates in the following steps:

1. Inventory Management Setup

• Staff add new products using an Inventory Management Form.
• Product details include:
  • Product Name
  • Available Stock
  • Minimum Stock Threshold
  • Product Price
• The workflow checks for duplicate products before saving.
• Valid products are stored automatically in Google Sheets inventory records.

2. Sales Entry & Billing

• Staff enter customer purchase details through a Retail Sale Entry Form.
• The workflow captures:
  • Customer Name
  • Phone Number
  • Product Name
  • Quantity
  • Payment Method
• Product stock is validated against inventory records.
• The system automatically calculates:
  • Total bill amount
  • Remaining stock quantity
  • Sale timestamp

3. Inventory Auto-Update

• After a successful sale:
  • Inventory stock is automatically reduced.
  • Updated stock values are synced to Google Sheets.
• This ensures real-time inventory tracking without manual calculations.

4. Low Stock Alert Automation

• The workflow continuously checks product stock levels.
• If stock drops below the configured minimum threshold:
  • A WhatsApp low-stock alert is sent to the manager automatically.
• This helps prevent stock shortages and missed sales opportunities.

5. Customer Receipt Notifications

  • Product Details
  • Quantity
  • Total Amount
  • Payment Method
  • Date & Time of Purchase

6. Stock Restock Automation

• Newly added stock is automatically merged with existing inventory quantities.
• Updated stock values are saved instantly to Google Sheets.

7. Daily Sales Summary Reporting

• A scheduled workflow runs automatically every day.
• The system calculates:
  • Total Daily Sales
  • Number of Orders
  • Top Selling Product
• Daily reports are saved in Google Sheets and delivered to the manager via WhatsApp automatically.
