GST-compliant invoices in under 3 minutes. E-way bills, multi-GSTIN support, GSTR export, and Tally integration — built around your workflow, not a generic template.
Generic billing software forces you into someone else's invoice format, someone else's product categorisation, and someone else's workflow. The result is slow billing, data entry errors, and compliance anxiety every quarter. NetAddons builds GST billing software that mirrors your actual sales process — from quotation to invoice to payment collection — with GST calculations, HSN codes, and e-Way Bills handled automatically.
Whether you run a retail shop in Kozhikode, a trading company with multiple warehouses, or a service firm with project-based billing, we configure every field, every print format, and every compliance export precisely for your requirements. One-time cost, lifetime ownership, free compliance updates during AMC.

Every feature is built for Indian compliance from day one — not bolted on as an afterthought.
Auto-calculate CGST/SGST/IGST based on supply type and party location. HSN/SAC codes, reverse charge flag, e-Invoice IRN generation for eligible businesses, and branded print templates.
Generate e-Way Bills directly from the invoice screen via NIC API integration. Auto-fill transporter details, vehicle number, and distance. Cancel and update e-Way Bills from the same interface.
Manage multiple GSTINs and branches from one login. Each GSTIN has its own invoice series, tax rates, and filing data while head office gets a consolidated dashboard.
Full ledger with outstanding invoices, credit notes, payment receipts, and ageing analysis. Send payment reminders by WhatsApp or email directly from the ledger screen.
Real-time stock updates on every sale and purchase. Batch tracking, reorder alerts, and stock valuation reports (FIFO/Average). Works across multiple warehouses and godowns.
Export GSTR-1 and GSTR-3B data in the official JSON format for direct upload to the GST portal, or in Excel for your CA. Reconcile with GSTR-2B to spot mismatches before filing.
From requirements to go-live with zero compliance risk.
We document your product/service categories, HSN codes, supply types, customer types, and filing frequency — then design the software to handle all of them automatically.
We design your invoice print format, credit note format, and dashboard screens — signed off before development so the final product looks exactly as expected.
Development with weekly demos. GST calculation accuracy is tested against real invoices before delivery. E-Way Bill and GSTR export are validated against the government portal.
We migrate your masters and opening balances, train your billing team, and run parallel billing for the first week to ensure accuracy before you switch fully.
Compliance expertise meets custom development — built by a team that operates in India and understands GST inside out.
GST rules change every year. Clients on our AMC receive compliance updates — e-Invoice thresholds, GSTR format changes, new HSN lists — within 7 days of official notification, at no extra charge.
Whether you need project-based invoicing, recurring billing, POS integration, or field-force mobile billing — we build it in. No workarounds, no plugins, no third-party add-ons.
No Tally renewal fees. No Zoho subscription. One development payment, then optional AMC if you want updates. The software runs on your server — not our cloud — so there's no dependency on us staying in business.
