📝 How to Use the Enhanced Indian Invoice System

Step 1: Set Up Your Company Details

Start by configuring your business information to personalize your invoices.

• Navigate to the "Settings" tab.
• Enter your Company Name, Address, and Contact Details (e.g., email and phone number).
• Upload a logo (PNG/JPEG) and adjust its size/position on the invoice preview using drag-and-drop or input fields.
• Tip: Save these details to auto-populate them on every invoice.

Step 2: Manage Your Inventory

Keep track of your stock to ensure accurate invoicing.

• Go to the "Stock" tab and add items with details like Item Code (e.g., LAP001), HSN/SAC Code (e.g., 8471), Description (e.g., Laptop Computer), Price (e.g., ₹25,000), Unit (e.g., PCS), Quantity, SGST/CGST (e.g., 9%), and Discount.
• Edit or delete items as needed; low stock (below 10 units) is highlighted in red.
• Validate stock levels to prevent overselling during invoice creation.
• Tip: Use the “Backup Stock Data” feature to save your inventory as a JSON file.

Step 3: Build Your Customer Database

Create a database of clients for faster invoicing and better relationship management.

• In the “Customer Database” tab, add customers with Contact Number (e.g., +919876543210), Name (e.g., Rajesh Kumar), Email, and Address.
• Edit or delete customers, and view their purchase history in the “Customer History” tab.
• Tip: Use autocomplete to quickly select customers by contact number or name when creating invoices.

Step 4: Create an Invoice

Generate professional invoices with ease.

• Open the “Create Invoice” tab. The invoice number (e.g., INV-001) and date (e.g., 2025-09-15) are auto-generated; adjust the due date if needed.
• Enter client details manually or use autocomplete to pull data from the customer database.
• Add items by typing an item code (e.g., LAP001) to auto-fill details or use the item dialog to select products.
• Specify Quantity, Discount (e.g., 5% or ₹100), and Discount Type. The tool calculates subtotal, taxes, and total automatically.
• Save the invoice to update inventory and store it in IndexedDB.
• Tip: Validate all fields to ensure compliance and sufficient stock.

Step 5: Share or Download the Invoice

Share invoices with clients or save them for your records.

• Click “Generate Invoice Preview” to review the invoice with your logo, client details, and totals (including discounts).
• Click “Generate PDF” to download a professional PDF (e.g., CompanyName_Invoice_INV-001.pdf).
• For WhatsApp sharing, enter the client’s number, preview the message (includes discounts, GST, and totals), and click “Send via WhatsApp.” Example message:

  Invoice from *Your Company Name*
  Invoice #: INV-001
  Date: 2025-09-15
  To: Rajesh Kumar
  
  Items:
  - Laptop Comp... (Qty: 2, Rate: ₹25000.00), Discount: 5%, SGST: 9%, CGST: 9% = ₹52500.00

Step 6: Monitor Your Business with the Sales Dashboard

Gain insights into your business performance.

• Check top-selling products and recent orders with clickable links to manage them.
• Tip: Use insights to optimize inventory and marketing strategies.

Step 7: Back Up and Restore Data

Protect your data with robust backup options.

• Export invoices to CSV for external analysis.
• Tip: Schedule regular backups to safeguard your business data.

💾 Why We Use IndexedDB: Advantages Over localStorage

The Enhanced Indian Invoice System uses IndexedDB, a powerful browser-based database, to store invoices, inventory, and customer data securely and efficiently. Unlike localStorage, which is limited and outdated, IndexedDB offers significant advantages that make our tool reliable and scalable.

What is IndexedDB?

IndexedDB is a modern, client-side database built into browsers, allowing the storage of large amounts of structured data like invoices and inventory. It acts like a mini-database, enabling fast, reliable, and offline data management.

Advantages of IndexedDB Over localStorage

• Larger Storage Capacity: localStorage is limited to 5–10 MB, while IndexedDB can store hundreds of MB, supporting thousands of invoices and inventory items.
• Structured Data: Unlike localStorage’s simple key-value pairs, IndexedDB supports complex data structures and indexing, enabling quick searches (e.g., finding invoices by customer).
• Asynchronous Operations: IndexedDB’s asynchronous nature keeps the tool responsive, unlike localStorage’s slower synchronous operations.
• Transaction Support: Ensures data consistency (e.g., inventory updates only if an invoice saves successfully), reducing errors.
• Scalability: Efficiently handles large datasets with fast querying, powering features like the Sales Dashboard.
• Offline Support: Works seamlessly offline, with IndexedDB’s capacity far exceeding localStorage.

How IndexedDB Powers Our Tool

• Data Persistence: Stores all data (invoices, inventory, customers) in IndexedDB for access even after closing the browser.
• Fast Autocomplete: Queries IndexedDB instantly for item and customer suggestions.
• Backup and Restore: Efficiently handles bulk data operations for reliable backups.
• Real-Time Updates: Updates inventory and customer records in a single transaction, ensuring accuracy.

By using IndexedDB with Dexie.js (a lightweight wrapper), our tool ensures cross-browser compatibility, security, and performance, making it a future-proof solution for your business.
