Generates compliant PDF invoices with mandatory Indian GST fields — HSN/SAC codes, GSTIN, place of supply, and tax breakdown. Everything runs locally in your browser.
Supplier and buyer GSTIN, invoice number and date, HSN/SAC codes per line item, taxable value, CGST+SGST (intra-state) or IGST (inter-state) breakup, and place of supply. The generator has no dedicated GST fields — type GSTIN, HSN, and tax splits into the business, client, item, and notes fields, and verify compliance yourself.
Use a continuous yearly series like INV/25-26/001 — tax authorities require sequential, gap-free numbering per financial year. Start a fresh series each April.
Business name, address, and contact blocks are editable text at the top of the invoice. There is no logo upload — keep a text header.
Use Print / PDF for emailing to clients and record-keeping (fixed layout, prints cleanly); use the text download when the client needs to copy line items.
No. Everything renders locally in your browser. No client names, amounts, or GSTINs are transmitted or stored.
The two sample lines (1 × $1,500 plus 1 × $120) subtotal $1,620.00, and with the 0% default tax the total is $1,620.00. Tax is one flat percent on the subtotal — set 18 for GST-style math — and the text export downloads under the invoice number.
