This page helps draft an invoice layout; it is not filing, e-invoicing, or GST verification software

An invoice generator is useful only when the user can see exactly what it includes and where its limits begin. Seller and buyer details, line items, taxable value, GST split, and totals are practical to generate in the browser, but that is not the same as return filing, e-invoicing compliance, or GSTIN validation.

This page generates a GST invoice draft from the details you enter. It is designed for quick invoice preparation and business-use previews, not for final tax compliance by itself.

How to use this GST Invoice Generator

  1. Enter seller and buyer details, then add line items with quantity, rate, and GST rate.
  2. Check whether the seller and buyer state relationship should produce CGST plus SGST or IGST.
  3. Review the full preview before PDF download, especially invoice number, date, tax split, and line-item details.

Where this page fits in the workflow

  • Builds a draft GST invoice with seller and buyer details, invoice rows, taxable value, GST split, and totals.
  • Switches between intra-state CGST plus SGST and inter-state IGST logic based on the state comparison used by the page.
  • Creates a printable preview locally in the browser before PDF download.

Invoice draft logic and compliance boundaries

The page totals taxable value from the item rows and then applies GST based on the rate entered for each row. It uses the seller and buyer state comparison on the page to decide whether the display should show CGST plus SGST or IGST.

That is useful for drafting and cross-checking totals, but it does not make the page a full compliance engine. E-invoicing rules, GST registration verification, and filing workflows still sit outside this generator.

Examples

Service invoice

  • Use case: Single service line with GST rate and invoice details
  • What to check: Correct tax split and final total

Useful for freelancers and service businesses that need a clean draft before they issue the final invoice from their own system.

Goods invoice

  • Use case: Multiple line items and quantity-based pricing
  • What to check: Item rows, taxable value, and GST totals

Use the preview to catch row-level errors before you share or print the invoice draft.

What this invoice generator does not do

  • Live GSTIN verification.
  • Return filing or e-invoicing compliance workflows.
  • Business-specific legal or tax review.

Privacy and data handling

The invoice preview and PDF is created locally in your browser on the page itself. The tool does not ask for an account before it builds the preview or download.

The page formats the details you enter into a draft invoice. It does not verify counterparties or submit anything to a tax system on your behalf.

Questions about using this draft

When does IGST apply?
Use IGST logic for inter-state transactions in the simplified flow on this page. Check your actual transaction details before final use.
Is GSTIN mandatory in every invoice case?
That depends on the business context and tax rules involved. This page helps format the draft invoice but does not decide every compliance rule for you.
Is this enough for filing?
No. The page creates an invoice draft. Filing, e-invoicing, and return workflows remain separate.
Does the page verify GST numbers?
No. Use the GSTIN validator or an official verification flow separately if you need that check.
Is the invoice generated locally?
Yes. The preview and PDF flow run locally in the browser during the normal generation flow.
