ZapInvoice - Free GST invoice generator for freelancer & Indian business.

ZapInvoice is a free, India-first GST invoicing tool built for freelancers, consultants, and small service businesses. Create a fully GST-compliant invoice in under 60 seconds. The tool automatically handles CGST/SGST (intra-state) and IGST (inter-state) splits based on your client's state, generates a UPI QR code on every invoice, and supports all 12 document types required under Indian GST law — Tax Invoice, Bill of Supply, Proforma Invoice, Credit Note, Debit Note, Export Invoice, and more.

Hey PH! 👋 I'm the founder of ZapInvoice — I built this after getting fed up with how painful GST invoicing is for Indian freelancers. Every tool I tried was either (a) built for the US/EU and completely ignored Indian tax law, or (b) full accounting software when all I needed was to send a clean invoice. So I built ZapInvoice: type in your details, pick a client, add line items — and get a fully GST-compliant PDF in under 60 seconds. CGST/SGST/IGST handled automatically. UPI QR on every invoice. 12 document types including Credit Notes, Debit Notes, Export Invoices, RCM Self-Invoices. 5 PDF templates. Plus free utility tools: GST Calculator, GSTIN Validator, Reverse GST Calculator, and Amount in Words. No account needed to try — 3 free invoices/month, no sign-up. Just go to zapinvoice.in and download a PDF right now. Would love your feedback — especially from Indian freelancers and small business owners! What else do you wish invoicing tools handled better? 🙏
