Add Customer Data
Use the Customer Database section to add client information. This enables autocomplete features when creating invoices.
Creating Your First Invoice
Enter Client Details
Start typing the client's contact number - if they exist in your database, their information will auto-populate. Otherwise, enter details manually.

Share or Print
Download as PDF, print directly, or share via WhatsApp using the integrated messaging features.
Advanced Features
Barcode Scanning
Use the scan button to add items via barcode scanning. Ensure your inventory items have barcode data entered for this feature to work.

Sales Analytics
Monitor your business performance with the Sales Dashboard. Filter by date ranges to analyze trends, top products, and customer activity.
WhatsApp Integration
Generate formatted messages for WhatsApp sharing. Customize description length and automatically include invoice totals and discount information.
Why IndexedDB Makes This System Superior
This system leverages IndexedDB, a powerful browser-based database technology that provides significant advantages over traditional storage methods:
IndexedDB operates asynchronously, ensuring your interface remains responsive even with large datasets.
Store thousands of invoices, products, and customer records locally without size limitations of traditional browser storage.
Efficient searching and filtering capabilities enable instant autocomplete and data retrieval across all records.
ACID-compliant transactions ensure data integrity - if an operation fails, your data remains consistent and uncorrupted.
Work completely offline - all data is stored locally in your browser, no internet connection required for daily operations.
Your business data never leaves your device unless you explicitly export it, ensuring complete privacy and security.
No server setup, no installation - works instantly in any modern browser with all your data preserved between sessions.
Automatic data management with no database maintenance, backups handled through simple JSON exports.
