About This Tool

This is a complete, browser-based billing tool built for Indian freelancers, consultants, and small businesses. Create GST invoices with CGST/SGST (intrastate) or IGST (interstate), proforma invoices for advance confirmation, and estimates or quotations — all from the same interface and templates.

Choose from three professionally designed PDF templates — Modern, Classic, and Minimal — and download any document as a pixel-perfect PDF. The preview updates live as you switch templates, so you always see exactly what your customer will receive.

New: UPI Payment QR on invoices. When your invoice is unpaid and your UPI ID is set in your business profile, simply tick Include payment QR code below the preview. A scannable upi:// QR is placed alongside the totals — in both the on-screen preview and the downloaded PDF. Your customer scans it with any UPI app (GPay, PhonePe, Paytm, BHIM) and the payment intent — with the exact invoice amount and your UPI ID — is pre-filled automatically.

Your business profile, saved customers, product/service catalog, and all invoices are stored in your browser's IndexedDB — private to your device, never uploaded anywhere. For peace of mind, enable persistent local storage (Toolist Settings → Storage) and install Toolist as a PWA from your browser's address bar — PWA installs tell the OS to protect the storage from being cleared by routine browser cache cleanups.

The Backup & Restore feature in Toolist Settings exports a complete JSON snapshot of all your data — business profile, customers, catalog, invoices, payments, and settings. Restore it anytime to the same or a different device. The GST Summary view gives you a month-wise breakdown of taxable turnover, CGST, SGST, and IGST across paid invoices, ready for GSTR-1 filing.

Frequently Asked Questions

What is the UPI payment QR code on invoices?

When your invoice is unpaid and you have a UPI ID saved in your business profile, a checkbox labelled Include payment QR code appears below the invoice preview. Tick it to embed a scannable UPI QR in both the preview and the downloaded PDF. The QR encodes a complete upi://pay deep-link with your UPI ID, business name, invoice amount, and invoice number pre-filled — so the customer just scans and confirms payment. No payment gateway or third-party service is involved. Need a standalone QR code? Try the QR Code Generator →

Which UPI apps can scan the invoice QR code?

Any app that supports the standard upi://pay intent: Google Pay, PhonePe, Paytm, BHIM, Amazon Pay, and most Indian bank UPI apps. When scanned, the app opens a payment screen with your UPI ID and the exact invoice amount already filled in — the customer just enters their PIN to complete payment.

Is this invoice generator free to use?

Yes, completely free — no sign-up, no subscription, no watermarks. All data is stored on your device. Optional persistent storage and full local backups are available from Toolist Settings.

Where is my data stored? Is it safe?

All data — your business profile, customers, catalog, and invoices — is stored in your browser's IndexedDB, private to your device. Nothing is sent to any server. For extra safety, enable persistent local storage in Toolist Settings (and install Toolist as a PWA so the OS protects your storage from routine browser cache cleanups). You can also export a full JSON backup at any time.

How do I back up and restore my invoices?

Open Toolist Settings (gear icon, top right) and go to the Storage section. Click Export Backup to download a complete JSON file containing your business profile, all customers, product catalog, every invoice, payment records, and settings. To restore, open Settings on the same or a different device and click Restore Backup, then select your JSON file. For a quick invoice-list export, use the Export Excel button on the Dashboard.

What is persistent storage and why does it matter?

By default, browsers can clear IndexedDB storage as part of routine cache cleanup — especially on low-storage devices. Enabling persistent storage asks the browser to protect your data from automatic eviction. For the strongest protection, install Toolist as a PWA from your browser's address bar (the install icon or 'Add to Home Screen'). PWA installs signal to the OS that the app's storage should be treated as persistent, the same way an installed app would be.

Can I create proforma invoices and estimates?

Yes. When creating a new document, choose between Tax Invoice, Proforma Invoice, and Estimate. All three document types use the same line-item form, templates, and PDF export. The document type label appears prominently on the header of the PDF.

Does it support IGST for interstate transactions?

Yes. For each invoice you choose between CGST+SGST (intrastate) or IGST (interstate). The totals section updates automatically, showing the correct tax split. You can also set GST to None for zero-rated or exempt supplies.

Can I download invoices as PDF?

Yes. After filling in the invoice, click Preview to see it in your chosen template (Modern, Classic, or Minimal), then click Download PDF. If the invoice is unpaid and has a UPI ID, you can include a scannable payment QR in the PDF — tick Include payment QR code before downloading.

What is the GST Summary view?

The GST Summary shows a month-wise breakdown of taxable turnover, CGST, SGST, and IGST collected across invoices, along with an HSN/SAC-wise summary table. Filter by month to pull the exact numbers needed for your GSTR-1 filing — no spreadsheet required.

Can I export invoices to Excel?

Yes. From the Dashboard, click Export Excel to download the current invoice list as an .xlsx file — useful for sharing with your accountant. For a full-fidelity backup that preserves customers, catalog, payment history, and settings, use the JSON Backup option in Toolist Settings.

Can I use this for non-Indian currencies?

Yes. The tool detects your browser locale and sets the currency automatically — USD, EUR, GBP, and others are supported. GST and HSN/SAC fields are shown only for INR; for other currencies those fields are hidden and a plain discount/tax invoice layout is used.
