Best GST Billing Software in India — E-Invoice, GSTR Filing & Tax Compliance

GST billing software is a digital tool that helps businesses create GST-compliant invoices, manage tax calculations, generate GST returns (GSTR-1, GSTR-3B), and handle E-Invoice and E-Waybill requirements. Since the implementation of GST in India in 2017, every registered business needs to issue GST-compliant invoices with correct GSTIN, HSN/SAC codes, tax calculations (CGST, SGST, IGST), and proper invoice numbering. Manual GST billing is error-prone and time-consuming. GST billing software like CODEAPPS automates the entire process, ensuring 100% compliance while saving hours of work.

E-Invoice Generation: From April 2025, E-Invoice is mandatory for businesses with turnover above ₹5 crore. Your billing software must support automatic E-Invoice generation with IRN (Invoice Reference Number) from the GST portal. CODEAPPS supports E-Invoice generation in Gold and Platinum plans.

E-Waybill: Required for movement of goods worth over ₹50,000. CODEAPPS automatically generates E-Waybill from the invoice data — no manual entry needed.

GSTR-1 & GSTR-3B Auto Filing: The software should auto-generate GSTR-1 (outward supply) and GSTR-3B (summary return) reports ready for filing. CODEAPPS generates all GST returns automatically from your invoices.

HSN/SAC Code Management: Automatic HSN code assignment based on product categories. CODEAPPS has a built-in HSN database.

Multi-GST Rate Support: Support for 0%, 5%, 12%, 18%, 28% GST rates and cess calculations. CODEAPPS handles all rate slabs automatically.

Credit/Debit Notes: For returns and adjustments, proper credit and debit note management with GST impact tracking.
