Need an invoice for another country?

This invoice includes the details usually required in India. Rules change and depend on your business, so check with your accountant. The tool adds up what you type and applies the rate you pick. It does not make an invoice valid or compliant.

What an invoice in India usually shows

Rule 46 of the CGST Rules lists what a tax invoice carries: your name, address and GSTIN, a consecutive invoice number of up to 16 characters that is unique in the financial year, the date, the client's details, the HSN or SAC code, a description, the value, the rate and amount of CGST, SGST or IGST, and the place of supply for supplies to another state. GST rates were reorganized on 22 September 2025 into mainly 5% and 18%, with 40% for a short list of items. Check the rate for your HSN or SAC before you send an invoice.

  • Same state: the rate is split in half between CGST and SGST. Other state: the full rate is IGST.
  • Exports, reverse charge, composition scheme and cess are not handled here. Ask your accountant if they apply.

E-invoicing

E-invoicing under GST (an invoice reference number from the government portal) applies to businesses above an aggregate turnover limit, which has been 5 crore rupees since 1 August 2023. A PDF from this tool is not an e-invoice and does not carry an IRN or QR code. Rules change and depend on your business, so check with your accountant.

Questions

Is this invoice generator free?

Yes. Make as many as you like, with no account. The PDF has a small "Made with ruam.ai" line at the bottom.

Is a invoice from this tool valid in India?

This invoice includes the details usually required in India. Rules change and depend on your business, so check with your accountant.

Does it work out tax for me?

It applies the rate you choose to the amounts you type. Which rate applies to what you sell is for you and your accountant to decide.

Where are my drafts and saved clients kept?

In this browser, on this device. Nothing is sent to Ruam. Clearing site data or using a private window removes them, so download the PDF of anything you need to keep.

How do I get a PDF?

Press Download PDF and choose Save as PDF in the print window. Only the invoice is printed, and the text stays selectable. If a required field is empty, it turns red and the download waits.

Can I bring in hours from a spreadsheet or time tracker?

Yes. Use Import from CSV above the totals. Columns such as date, description, hours and rate are recognized, and any bad row is listed so you can fix it. Ruam paid plans export hours as CSV by person or project.

The hours for your invoice, already counted.

Ruam counts work hours on its own, by project and client, with no screenshots. When it is time to invoice, the hours are already there.

Free forever for one person. Teams get 7 days free, no card.
