Why Choose Our Offline POS & Quotation Management System?
Most modern billing software requires constant internet connectivity and forces you to upload your sensitive financial and customer data to remote third-party servers. We have revolutionized this process by leveraging powerful browser-based IndexedDB technology.
1-Click Estimate to Invoice
Create detailed Quotations for your clients. Once approved, simply go to Reports and convert the quotation into a final tax invoice with a single click—no double data entry required.
100% Offline Privacy
Your client details, purchase history, and sales data never leave your local computer. It operates entirely within your browser for ultimate security.
Lightning Fast POS
No loading screens or server delays. Search items by name, SKU, or use a barcode scanner to add products to the cart instantly and generate bills in seconds.
Dynamic Tax & Currency
Customize tax labels (GST, VAT, Sales Tax) and select your local currency symbol (₹, $, €, £). The system auto-calculates SGST and CGST splits effortlessly. For detailed tax and profit planning, you can also use our free GST Margin Calculator.
How to Use the Free Invoice Generator Tool
Our system is divided into highly intuitive modules. Here is a step-by-step guide to setting up your new digital business ledger:
Set Up Your Business Profile
Navigate to the Business Profile tab. Enter your shop or company name, address, contact details, and upload your logo. Set your preferred currency and tax labels. This information acts as the professional header for every PDF estimate and invoice you generate.
Create Quotations or Final Bills
Open the Create Bill (POS) tab. Select a client, scan barcodes or search for products. In the PDF preview section, you can choose to save the document as a Quotation (which does not deduct stock) or as a final Invoice (which updates your live inventory).
Record Supplier Purchases
Use the Purchase Entry tab when receiving new stock. Select your supplier, add items to the cart, and log the bill. This action automatically updates your real-time inventory count and creates a ledger entry for your supplier.
Secure Your Data (Cloud Sync & Backup)
Since this tool works offline, safeguarding your data is crucial. Visit the Backup / Restore tab to download a complete local `.zip` file of your database, or log in with your Google account to activate an automated 30-day rolling cloud backup on Google Drive.
Advanced Purchase & Supplier Ledger Management
Managing accounts payable is critical for the financial health of any business. Our software includes a dedicated Supplier Ledger. When you make a purchase, you can enter the amount paid upfront and the remaining balance due. As you make subsequent payments over the month, simply use the Purchase History section to "Pay Balance."
The system intelligently uses a FIFO (First-In, First-Out) method to adjust these payments against your oldest pending bills automatically, ensuring your accounting remains accurate. You can also export a detailed CSV report of all supplier transactions to share with your CA or accountant.
Pro Tip for Freelancers & Service Providers
Send a Quotation to your client first. When they approve the costs, head over to the Reports & History tab, find the quotation, and click the "Convert to Invoice" button. The system will instantly turn it into a final bill and update your sales dashboard automatically!
Frequently Asked Questions (FAQs)
1. Can I create quotations or estimates with this tool?
Yes! You can easily generate professional PDF Quotations or Estimates for your clients. Once the client approves, you can convert that estimate into a final invoice with a single click without re-entering any product details.
2. Is my financial data safe and secure?
Yes. The entire application runs client-side. We do not have backend servers or databases collecting your sales, inventory, or client information. Everything is saved directly inside your current web browser's local storage.
3. Do I need to create an account or sign up to use this tool?
No signup, registration, or login is required to use the billing, quotation, and inventory features. The only time a login is requested is if you choose to connect your own Google Drive for cloud backups.
4. What happens if I clear my browser history?
If you clear your browser's "Site Data" or "Cookies", your database will be erased. It is highly recommended to use the Backup / Restore feature daily to save your data to Google Drive or export it as a local ZIP file.
5. Does the invoice generator support GST / VAT calculations?
Absolutely. You can define your specific tax rate per product in the inventory. The POS system automatically calculates the tax breakdown (e.g., auto-splitting CGST and SGST for Indian businesses) and displays a clean tax summary table on the final PDF invoice.
6. Is there a limit on how many invoices or items I can add?
There are absolutely no limits imposed by our software. You can generate unlimited quotations, invoices, add unlimited products, and manage as many suppliers as your device's local storage capacity allows.
