Under India's Goods and Services Tax regime, every registered business must issue a GST-compliant invoice for every taxable supply. A proper GST invoice is not just a payment request — it is the primary document used by your buyer to claim Input Tax Credit (ITC). Errors in your invoice can prevent your clients from claiming ITC, damaging your business relationship and credibility.
SimpleInvoice's GST invoice generator for India ensures every invoice you generate includes all mandatory fields prescribed by the GST Act: your GSTIN, your buyer's GSTIN (for B2B), place of supply, HSN/SAC codes, and separate tax breakdowns for CGST, SGST, and IGST.
One of the most confusing aspects of GST invoicing for new business owners is knowing when to charge CGST + SGST versus IGST. The rule is straightforward: if your buyer is in the same state as you, you charge CGST and SGST (split equally). If the buyer is in a different state, you charge IGST (equal to CGST + SGST combined).
SimpleInvoice automatically applies the correct tax split based on your business state and client configuration. You simply enter the tax rate (e.g., 18%) and the system splits it correctly — eliminating a common source of GST errors.
According to the CGST Act, a valid tax invoice must include:
SimpleInvoice's GST invoice template automatically includes all these fields. You simply fill in the values — the layout and compliance are handled for you.
For B2B transactions (business to business), the buyer's GSTIN must be included on the invoice so they can claim Input Tax Credit. SimpleInvoice lets you save client GSTINs in the client profile, so they appear automatically on every new invoice.
For B2C transactions (business to consumer), GSTIN is optional but the invoice must still show the tax breakdown. SimpleInvoice handles both scenarios without requiring you to manage separate invoice templates.
GSTR-1 (outward supplies) requires you to report each invoice with its taxable value and tax amounts split by tax rate. SimpleInvoice's reports section summarises your invoices by GST rate, making it easy to transfer the numbers into your GSTR portal. While SimpleInvoice does not directly file GST returns, it keeps all the invoice data organised so your CA or tax consultant can prepare returns quickly.
