Frequently Asked Questions
What details are mandatory on a GST invoice? +
Mandatory fields: supplier name, address & GSTIN; invoice number & date; recipient name & address; HSN/SAC code; description, quantity & value; taxable value; GST rate & amount (CGST+SGST or IGST); total value. For supplies above Rs.50,000 to unregistered buyers, recipient address is also required.
What is the difference between a Tax Invoice and Bill of Supply? +
A Tax Invoice is issued by GST-registered suppliers for taxable supplies — it shows CGST, SGST or IGST. A Bill of Supply is issued for exempt supplies or by Composition dealers who cannot charge GST. Composition dealers must issue Bills of Supply, not Tax Invoices.
Is HSN code mandatory on GST invoices? +
Yes — based on turnover: up to Rs.5 crore needs 4-digit HSN; above Rs.5 crore needs 6-digit HSN. For services, use SAC codes. From April 2021, HSN/SAC codes are mandatory for all B2B invoices.
Can I generate a GST invoice without a GSTIN? +
If your turnover is below the threshold (Rs.20L for services, Rs.40L for goods), you are not required to register and cannot charge GST. You can still use this tool to generate a professional invoice — simply leave the GSTIN field blank.
What is the time limit for issuing a GST invoice? +
For goods: at or before delivery. For services: within 30 days of supply (45 days for banks/NBFCs). For continuous services: within 30 days of each payment due date. Late invoicing can cause ITC issues for the recipient.
