What is a GST invoice? +
A GST invoice is a document issued by a registered seller that shows details of the supply (buyer/seller info, HSN/SAC, quantity, value) and the tax charged (CGST/SGST/IGST/cess) as per GST law.
Why is a GST invoice important? +
It ensures compliance and enables your buyer to claim Input Tax Credit (ITC). Proper invoices also reduce audit risk and payment disputes.
Can I generate a GST invoice online? +
Yes. With hisabkitab you can create compliant invoices in under 30 seconds, with automatic tax calculation and mandatory fields prefilled.
What are the mandatory fields in a GST invoice? +
Supplier and buyer details (with GSTIN for B2B), invoice number (≤16 characters) and date, HSN/SAC, item description, quantity, rate, taxable value, CGST/SGST/IGST/cess breakup, place of supply, total value, and authorised signature.
How many copies of a GST invoice are required? +
Goods: 3 copies (original for buyer, duplicate for transporter, triplicate for supplier). Services: 2 copies (buyer and supplier).
What is the time limit for issuing a GST invoice? +
Goods: on/before removal or delivery. Services: within 30 days of supply (45 days for banks/NBFCs).
Can I issue a GST invoice without a GSTIN? +
No. A valid GSTIN of the supplier must appear on the invoice for it to be compliant under GST.
What is a Bill of Supply and when is it used? +
It’s issued when tax is not charged (e.g., composition dealers or exempt supplies). It doesn’t show tax amounts or allow ITC.
How is e-invoicing different from a normal GST invoice? +
E-invoicing is the electronic authentication of B2B invoices on the IRP which generates an IRN and QR code. It’s mandatory above the notified turnover threshold.
Which software is best for creating GST invoices? +
hisabkitab is a simple, cloud-based solution with auto GST calculation, templates, and exports (PDF/Excel/Word). It’s built for Indian SMEs and professionals.
