Frequently Asked Questions

Is this invoice legally valid for GST purposes in India?

The AWE-OS Invoice Generator creates invoices that include all mandatory fields required under the CGST Act 2017 and GST Invoice Rules 2017: supplier name and GSTIN, invoice date and number, buyer details (GSTIN for B2B), description of goods/services, HSN/SAC code, taxable value, applicable GST rate, and CGST/SGST/IGST amounts. However, the legal validity of a GST invoice depends on the supplier being a registered taxpayer who files GST returns. The tool provides the correct format — you must ensure your GSTIN is valid and you are compliant with your GST filing obligations under GSTR-1 and GSTR-3B.

What is the difference between a GST invoice and a bill of supply?

A GST Tax Invoice is issued by GST-registered businesses for taxable supplies — it shows the GST charged and allows the buyer to claim Input Tax Credit (ITC) on purchases used for business. A Bill of Supply is issued instead of a tax invoice when supplying exempt goods/services or when the supplier is under the Composition Scheme and cannot charge GST. Exporters also issue a Bond/LUT-backed invoice without GST for zero-rated exports under the Integrated GST framework. The AWE-OS Invoice Generator creates standard GST Tax Invoices suitable for most B2B and B2C transactions by regular GST-registered taxpayers.

Do I need to register for GST to raise a GST invoice?

You must be a GST-registered business with a valid GSTIN to issue a GST Tax Invoice and collect GST from customers. If your annual turnover is below ₹40 lakh (₹20 lakh for service providers, ₹10 lakh for businesses in special category states like Himachal Pradesh, Uttarakhand, and northeastern states), GST registration is not mandatory and you should not charge GST. Businesses below the threshold can issue regular invoices without GST. If you are above the threshold and not registered, collecting GST without a GSTIN is illegal under Section 122 of the CGST Act and can result in penalties equal to the tax evaded or ₹10,000, whichever is higher.

Tips & Best Practices

Include your 15-digit GSTIN on every GST invoice for B2B transactions — without a valid GSTIN, your buyer cannot claim Input Tax Credit (ITC) on the purchase, which is a significant commercial disadvantage for business-to-business transactions.
Use the correct HSN (Harmonized System of Nomenclature) code for goods or SAC (Services Accounting Code) for services — incorrect codes attract GST department queries and may require amendment of your filed GSTR-1 return.
Set a unique invoice number for each invoice and maintain a sequential numbering system — GST law requires invoice numbers to be unique and sequential within each financial year. Starting fresh each April 1 is the standard practice.
Specify the "Place of Supply" accurately — for intra-state supplies, place of supply is the same state as delivery, attracting CGST+SGST. For inter-state supplies, place of supply is the destination state, attracting IGST.
For advance payment invoices (proforma invoices), clearly mark them as "PROFORMA INVOICE" — these are not valid GST tax invoices and do not need to be reported in GSTR-1. Raise a proper tax invoice when the supply is made.
Add bank account details (bank name, branch, IFSC code, account number) to the invoice for faster payment — Indian business buyers commonly pay by NEFT or RTGS, and having banking details on the invoice removes a friction point.

Common Mistakes to Avoid

Raising a GST invoice without being GST-registered — only businesses with a valid GSTIN can issue GST invoices and collect GST from customers. Issuing a GST invoice without registration attracts penalties under Section 122 of the CGST Act.
Using the wrong GST rate for your service or product — every taxable supply has a specific rate under the GST tariff schedule. Using 18% for a 12% item (or vice versa) creates a GST mismatch and requires a credit note and revised invoice.
Forgetting to mention the invoice date — the GST invoice date determines which GST return period the invoice belongs to. Missing dates can cause inclusion in the wrong filing period during audits.
Not including the Place of Supply field — this field determines whether CGST+SGST or IGST applies and is mandatory under GST Invoice Rules for tax invoices. Omitting it makes the invoice technically non-compliant.
Using the same invoice number for multiple invoices or reusing numbers from the previous financial year — GST law requires unique sequential invoice numbers within each financial year. Duplicates cause reconciliation failures in GSTR-1 vs GSTR-2A matching.
Issuing a bill of supply when a tax invoice is required (for regular GST-registered suppliers of taxable goods/services) — a bill of supply is only for exempt supplies and composition scheme taxpayers. Using the wrong document type is a compliance error.
