GST发票生成器

A GST invoice is a document issued by a registered supplier listing the goods or services sold, applicable tax rates (CGST, SGST, or IGST), HSN/SAC codes, and the total amount. It is mandatory for all taxable supplies under the Goods and Services Tax Act, 2017. Our generator creates fully compliant invoices that meet all 16 mandatory fields specified in CGST Rule 46.

The tool automatically determines the tax type based on the supplier's state and the place of supply. If both are the same state (intra-state supply), it splits the GST into equal CGST and SGST. If they differ (inter-state supply), it charges the full rate as IGST. This happens automatically when you set the supplier state and place of supply.

Yes. The tool validates the full 15-character GSTIN format including the 2-digit state code against all 38 valid Indian state codes, the PAN structure (chars 3-12), and the check digit using the Luhn Mod 36 algorithm. It also auto-fills the PAN and detects the state code from the GSTIN.

The tool includes a searchable database of 50+ common HSN codes (for goods) and SAC codes (for services) covering IT, consulting, construction, food, electronics, textiles, and more. You can also enter any custom HSN or SAC code manually. HSN codes are mandatory for businesses with turnover above ₹1.5 crore.

CGST (Central GST) and SGST (State GST) are charged on intra-state supplies (buyer and seller in the same state). IGST (Integrated GST) is charged on inter-state supplies (buyer and seller in different states). The total tax rate remains the same — for example, 18% GST is split as 9% CGST + 9% SGST for intra-state, or charged as 18% IGST for inter-state.

A GST invoice must include: supplier name, address and GSTIN; a unique invoice number (max 16 characters); invoice date; recipient details with GSTIN (for B2B); description of goods/services; HSN or SAC code; quantity and unit; taxable value; tax rate and amount (CGST/SGST or IGST); total amount; and place of supply for inter-state transactions. Our tool tracks all these requirements with the 8-point compliance checker.

Yes. Select 'Bill of Supply' as the document type. Bills of supply are used by composition scheme dealers or for exempt supplies where GST is not charged. The tool automatically hides tax columns and adjusts the format accordingly.
