Is the Invoice Generator tool safe to use?

Local operations process document content on your device. External-service operations may send inputs as described in the processing note. Keep originals and inspect the output.

Does this invoice comply with GST regulations?

This is a plain invoice without GST breakdown — appropriate for non-GST registered businesses or for businesses billing for items/services exempt from GST. If you are GST registered and your client is a business, use our GST Invoice Generator which includes mandatory fields like GSTIN, HSN/SAC codes, and CGST/SGST breakdown.

How do I save the invoice as a PDF?

Click the 'Print / Save as PDF' button. In the print dialog, change the destination to 'Save as PDF' (Chrome) or 'Print to PDF'. Adjust margins to 'None' or 'Minimal' for a clean A4 PDF. The form fields are hidden in print view for a professional document.

Is there a legal requirement to number invoices sequentially?

For GST-registered businesses, sequential invoice numbers within a financial year are mandatory. For unregistered businesses, sequential numbering is a best practice for accounting and bookkeeping. The format can be anything (INV-2025-001, F2025/01, etc.) as long as it is unique and sequential.

What should I put in the notes section?

Payment instructions: bank name, account number, IFSC code, and UPI ID. Payment terms (e.g., 'Payment due within 15 days of invoice date'). Late payment charges if applicable. Any project-specific terms. Tax deduction information (e.g., 'Please deduct TDS under Section 194J at 10% before payment').
