Free GST Invoice Generator for Indian Freelancers, Consultants & MSMEs
Issuing legally valid invoices in India requires strict adherence to Central Board of Indirect Taxes and Customs (CBIC) rules and the Goods and Services Tax (GST) Act. Whether you are an independent software developer in Bengaluru, a digital marketing consultant in Delhi, a creative professional in Mumbai, or a registered MSME in Pune, InvoiceFast provides an India invoice generator specifically engineered for Indian commercial taxation.
Our generator defaults automatically to INR (₹) — Indian Rupee, handles all Indian GST slabs (5%, 12%, 18%, and 28%), supports consecutive financial-year serial numbering under Rule 46, renders UPI payment QR codes directly onto the invoice, formats amounts in Indian words (Lakhs and Crores), and compiles print-ready A4 PDF invoices instantly in your browser without transmitting any private financial records to remote servers.
Rule 46 of CGST Rules: Mandatory Tax Invoice Inclusions
To qualify as a valid tax invoice that enables your corporate clients to claim Input Tax Credit (ITC) under Section 16 of the CGST Act, your invoice must clearly disclose:
Supplier Details: Your legal name, registered commercial address, and 15-character alphanumeric GSTIN (Goods and Services Tax Identification Number).
Consecutive Serial Number: A sequential invoice number containing only alphabets, numerals, and special characters (hyphen - or slash /), unique for the financial year, and not exceeding 16 characters (e.g., INV/2026-27/042).
Date of Issue: The exact date the invoice is raised.
Recipient Details: Customer name, billing address, and GSTIN or UIN (if the client is registered for GST).
HSN or SAC Code: Harmonized System of Nomenclature (for physical goods) or Services Accounting Code (e.g., SAC 998311 for management consultancy or 998314 for web development).
Taxable Value & GST Breakdown: Clearly segregated subtotal, applicable GST rate, and tax amounts. For intra-state sales (same state), split into equal halves of CGST + SGST. For inter-state sales (different states), bill as IGST.
Place of Supply: State name and 2-digit state code (e.g., Maharashtra: 27, Delhi: 07, Karnataka: 29, Tamil Nadu: 33).
Total in Words: Mandatory in Indian commercial banking and accounting reconciliation.
GST Registration Thresholds in India (Service Providers vs Goods)
Understanding when you are legally required to register for GST protects your business from penalties:
Service Providers & Freelancers: Registration is mandatory once aggregate turnover in a financial year exceeds ₹20 Lakhs (or ₹10 Lakhs in Special Category States like Manipur, Mizoram, Nagaland, and Tripura).
Suppliers of Goods: The threshold is ₹40 Lakhs for intra-state supply of goods (or ₹20 Lakhs in special category jurisdictions).
Turnover Below Threshold: If your annual turnover is below the statutory limit, you do not need to register for GST. You can issue clean non-GST commercial invoices using InvoiceFast by setting the GST % field to 0 and leaving out the GSTIN.
Exporting Services to US & Overseas Clients (Zero-Rated Supply & LUT)
If you are an Indian freelancer or agency billing overseas clients in the USA, UK, Europe, or Australia:
Under Section 16 of the Integrated Goods and Services Tax (IGST) Act, export of services is categorized as a Zero-Rated Supply.
You can file a Letter of Undertaking (LUT) via Form GST RFD-11 online on the GST portal at the beginning of each financial year. This permits you to export services at 0% IGST without paying tax upfront.
InvoiceFast allows you to bill foreign clients in USD ($), EUR (€), GBP (£), or INR, and add your LUT reference number (e.g., LUT Ref: AD2704260012345) directly in the Notes field. Always request a Foreign Inward Remittance Certificate (FIRC) or BIRC from your bank to substantiate the export transaction.
Instant Settlement: UPI QR Codes & IMPS/NEFT Banking Details
Never wait weeks for client payments. InvoiceFast supports rapid Indian settlement channels:

Case Study: Exporting Software Services at 0% IGST under LUT
The Scenario: Rahul, an independent mobile app developer in Pune, began billing a tech startup in San Francisco $6,000 per month. Without understanding export rules, he wondered if he had to charge 18% GST to an American entity.
The Solution: Under Section 16 of the IGST Act, Rahul filed Form GST RFD-11 (Letter of Undertaking) online in 5 minutes. Using InvoiceFast, he selected USD ($) currency, set the GST % to 0, and quoted his ARN LUT reference in the invoice notes. He received payment via wire transfer in foreign currency and secured an e-FIRC from his bank, legally achieving 0% tax liability on his export revenue.
India Invoice Generator — Frequently Asked Questions
A Letter of Undertaking (LUT) filed through Form GST RFD-11 on the GST portal permits registered Indian exporters and freelancers to bill clients outside India at 0% IGST without paying tax upfront. You must receive payments in convertible foreign exchange (e.g., USD, EUR, GBP) and obtain a Foreign Inward Remittance Certificate (FIRC) from your bank.
Indian corporate clients are legally required under Section 194J of the Income Tax Act to deduct TDS (typically 2% or 10% for professional services) from your taxable subtotal before releasing payment. They remit this TDS to the Income Tax Department against your PAN, which reflects in your Form 26AS / AIS for year-end tax credits.
Under Rule 46 of the CGST Rules 2017, a tax invoice must contain: the supplier's name, address, and 15-digit GSTIN; a consecutive invoice serial number (up to 16 characters, unique per financial year); date of issue; recipient's name, address, and GSTIN (if registered); HSN code (goods) or SAC code (services); description of services; total value and taxable value; GST rate and split (CGST + SGST for intra-state, or IGST for inter-state); place of supply with state code; and signature or digital stamp.
For service providers and freelancers, GST registration is legally mandatory once aggregate annual turnover exceeds ₹20 Lakhs (₹10 Lakhs for special category states such as Manipur, Mizoram, Nagaland, and Tripura). If your turnover is below this threshold, GST registration is optional, and you can issue regular commercial invoices with 0% tax.
For intra-state transactions (where supplier and client are in the same state), GST is split equally into CGST (Central GST) and SGST (State GST) — for example, 9% CGST + 9% SGST on an 18% service. For inter-state transactions (supplier and client in different states), Integrated GST (IGST) is charged at the full rate of 18%.
Export of services is treated as a 'Zero-Rated Supply' under Section 16 of the IGST Act. Indian freelancers can export services without paying IGST by submitting a Letter of Undertaking (LUT) online on the GST portal at the start of each financial year, and receiving payment in convertible foreign exchange.
Services Accounting Codes (SAC) classify services under GST. For example, SAC 998311 is for management consulting, 998313 for IT infrastructure and network services, and 998314 for web design and development. You can enter your 6-digit SAC code directly into the line item description or the Notes section in InvoiceFast.

Yes. InvoiceFast automatically translates your grand total into words using the Indian numbering system (e.g., 'One Lakh Fifty Thousand Rupees Only') on the live preview and the downloaded PDF, fulfilling the commercial convention required across Indian accounting and tax audits.
