What is a GST invoice generator? A GST invoice generator is a free tool that creates tax-compliant invoices for Indian businesses โ automatically calculating CGST/SGST (intra-state) or IGST (inter-state), applying the correct GST rate by HSN/SAC code, and producing a professional PDF in seconds.

As finance expert ICAI notes: "A well-structured GST invoice is the first defence in any audit โ accuracy, sequence, and disclosure protect both the seller and the buyer's input tax credit."

Standard GST slabs notified by the CBIC. Always check current rates for your specific HSN/SAC code.
๐ Intra-state vs Inter-state: If your state matches the client's Place of Supply, GST splits into CGST + SGST (Central + State). If states differ, use IGST (Integrated). Example: โน10,000 sale at 18% GST within Maharashtra = CGST โน900 + SGST โน900. Sale from Maharashtra to Karnataka = IGST โน1,800.
Industry Insights: Who Uses Invoice Generators Every Day?
๐ผ Freelancers, Consultants & Independent Professionals in Pune
India has an estimated 15 million+ freelancers (source: NASSCOM), with Pune emerging as one of the top three freelance hubs after Bengaluru and Mumbai. Freelance designers, developers, writers, and consultants in Wakad, Hinjewadi, Kharadi, and Baner need GST-compliant invoices if their annual turnover exceeds โน20 lakh (services) or if they are registered under GST. This tool auto-calculates CGST/SGST or IGST, includes HSN/SAC codes, and generates a PDF that complies with Rule 46 of the CGST Rules.
๐ข Small & Mid-Sized Businesses (SMBs) in Pimpri-Chinchwad & PCMC
Pimpri-Chinchwad is one of India's largest manufacturing hubs, with over 1 lakh registered MSMEs. Manufacturing suppliers, small traders, and B2B vendors in Bhosari, Chakan, and Talegaon use GST invoices daily for inter-state and intra-state transactions. Our tool handles multiple items, mixed HSN codes, and different GST rates per line item โ critical for complex industrial billing.
๐จ Creative Agencies & Digital Marketing Firms
Digital marketing agencies, web design studios, and advertising firms across Pune (Wakad, Baner, Kothrud) bill clients for services at 18% GST (SAC 998314 for IT services, SAC 998361 for advertising). Agencies often work with international clients where invoices are issued in USD/EUR/GBP. Our multi-currency support lets agencies switch between currencies with a single dropdown while keeping Indian rupee invoices GST-compliant.
๐๏ธ Real Estate Agents, Property Consultants & Brokers
Real estate agents and brokers in Pune, Wakad, Hinjewadi, and Pimpri-Chinchwad charge brokerage commissions with GST at 18%. Property consultants may issue either commission invoices or composite service invoices. Our tool lets agents save client details for repeat transactions โ critical for brokers who invoice the same clients multiple times per year.
Healthcare services in India are largely GST-exempt, but associated services like medical equipment sales, health check-up packages for corporates, wellness programs, and consultancy may attract GST. Clinics in Pune and PCMC often use this tool for corporate wellness invoices, medical tourism packages, and equipment sales to other hospitals.
Education services are exempt from GST when provided by recognized institutions โ but private coaching, online course sales, corporate training, and professional workshops by independent trainers attract 18% GST. Tutors and coaches in Pune, especially near Hinjewadi's IT corridor, use this tool to issue compliant invoices to parents, students, and corporates.
๐ Logistics, Transport & Delivery Businesses
GST for transportation services in India ranges from 5% (goods transport agency, no ITC) to 12% (services like courier, logistics) or 18% (chartered transport). Truck operators in Pimpri-Chinchwad's industrial belt issue hundreds of invoices monthly. Our tool handles multiple line items with different GST rates and generates a printable PDF for physical LR (Lorry Receipt) filing.
Frequently Asked Questions
What is a GST invoice and why is it mandatory in India?
A GST invoice (also called a tax invoice) is a document that GST-registered businesses must issue to their customers when supplying goods or services. Under Rule 46 of the CGST Rules, 2017, it must contain: consecutive invoice number, date, customer name and address, GSTIN of seller and buyer, HSN/SAC codes, description of goods/services, quantity, taxable value, tax rate, CGST/SGST or IGST breakdown, and total amount. Non-compliance can attract penalties of up to โน25,000 per offence under Section 122 of the CGST Act. Our tool generates fully compliant invoices by default.
What is the difference between CGST, SGST, and IGST?
CGST (Central GST) and SGST (State GST) apply to intra-state transactions โ sales where the seller's state matches the buyer's Place of Supply. The GST rate is split equally between them: 18% GST = 9% CGST + 9% SGST. IGST (Integrated GST) applies to inter-state transactions โ sales across state borders. The full rate goes to the Centre, which then transfers the state's share. Example: โน1,00,000 sale from Maharashtra to Maharashtra at 18% GST = CGST โน9,000 + SGST โน9,000. From Maharashtra to Karnataka = IGST โน18,000. Our tool auto-detects this based on your state and the client's Place of Supply.
What are HSN and SAC codes?
HSN (Harmonized System of Nomenclature) codes classify goods โ mandatory on invoices for turnover above โน5 crore. SAC (Service Accounting Code) classifies services โ all service invoices must include SAC codes. Common SACs: 998314 (IT design services), 998361 (advertising), 998313 (IT consulting), 998399 (other professional services). Our tool includes an HSN/SAC column on every line item so you can add the correct code.
Can I use this tool to generate invoices in USD or other currencies?
Yes. Our tool supports INR, USD, EUR, GBP, AED, AUD, CAD, and SGD. This is useful for freelancers and agencies billing international clients, especially in the IT, design, and consulting sectors. For Indian GST compliance, note that export invoices follow a slightly different format (LUT/bond reference, FIRC details) โ always consult a CA for export invoicing.
What invoice number format should I use?
GST rules require consecutive serial numbers โ no gaps allowed. Common formats: INV-2026-001, FY26/0001, or 2026-27/001. Maximum 16 characters per Rule 46(b). Do not reuse numbers within a financial year. Our tool lets you enter any format and includes it on the invoice.
What is Place of Supply and why does it matter?
Place of Supply is the state where the goods/services are deemed to be consumed for GST purposes. For services, this is typically the client's location (or registered address for registered clients). For goods, it's the delivery address. Place of Supply determines whether CGST+SGST or IGST applies. Our tool uses your state (from the business address) and the client's Place of Supply to auto-detect the correct tax type.
Can I add a logo to my invoice?
Yes. Click "Click to upload logo" in the Business section and select any PNG or JPG. Logos are rendered at the top of the invoice. For best results use a transparent PNG (200ร60px recommended). Your logo is stored only in your browser and never uploaded to any server.
Can I add a UPI QR code or Razorpay payment link to my invoice?
Yes. Enter your UPI ID (e.g. yourname@upi) and we'll generate a QR code that customers can scan to pay instantly. You can also add a Razorpay payment link (e.g. https://rzp.io/l/xxxxxx) which appears as a clickable button on the invoice PDF. This lets clients pay by card, net banking, or wallet.
How do I download the invoice as PDF?
Click the "Download PDF" button or "Print / Save as PDF". If using the print dialog, select "Save as PDF" as the printer destination. Our print CSS hides the tool UI and shows only the invoice on a clean A4 page. You can also use the "Share on WhatsApp" button to send the invoice via WhatsApp Web.
Does this tool save my invoices or client data?
Yes โ but only in your browser, using your device's local storage. Click "Save Invoice" to store an invoice; click "Save Client" to store a client profile. Nothing is sent to any server, database, or third party. Your data stays 100% private and offline. Clearing your browser data will erase saved invoices.
What if I don't have a GSTIN?
If you're not GST-registered (e.g. freelancer with turnover under โน20 lakh for services), you can leave the GSTIN field blank and set tax type to "No Tax". Your invoice becomes a standard non-GST invoice with "Bill of Supply" or "Invoice" as the header. However, you cannot charge GST on such invoices.
How long must GST invoices be retained?
Under Section 36 of the CGST Act, GST invoices must be retained for 6 years from the due date of filing the annual return for that financial year. For companies under audit, records must be retained until the audit is complete. Always keep digital and physical copies.
Is my invoice data safe with this tool?
Absolutely. All calculations run 100% in your browser using JavaScript. Your invoice data (client details, amounts, GSTINs) is never transmitted to any server, database, or third party. You can use the tool offline after loading the page once.
Is this invoice generator free?
Yes โ completely free, no signup, no watermark, no invoice limit. Brought to you by Endeavour Marketing, a digital marketing agency in Pune, India.
