How do I create a GST invoice for free in India?

What is the mandatory format for a GST invoice in India?

A valid GST tax invoice must include: supplier name, address, and GSTIN; unique sequential invoice number; invoice date; recipient name, address, and GSTIN (for B2B); HSN/SAC code; description of goods or services; taxable value; GST rate; CGST and SGST or IGST amounts separately; place of supply; and total value in words and figures.

Can I send a GST invoice on WhatsApp?

Yes. Ozydo generates a professional GST invoice PDF and lets you share it directly on WhatsApp with one tap — without downloading and re-uploading the file. This is the fastest way to send invoices to clients in India.

What is the difference between CGST, SGST, and IGST?

CGST (Central GST) and SGST (State GST) apply to intra-state sales — within the same state. They are each half of the total GST rate (e.g., 18% GST = 9% CGST + 9% SGST). IGST (Integrated GST) applies to inter-state sales — between two different states — and equals the full rate.

Do freelancers need to charge GST on invoices?

Only if your annual service income exceeds ₹20 lakh (₹10 lakh in some North-East states). Below this threshold, you do not need to register for GST and can invoice without charging GST. Above the threshold, GST registration is mandatory and you must charge 18% GST on most services.

What is the best free invoice app for small businesses in India?
