GST compliance for Tamil Nadu
Every business registered in Tamil Nadu carries GST state code 33 — the first two digits of its GSTIN. 399Apps generates GST-compliant invoices with correct HSN/SAC codes, keeps your GSTR-1 and GSTR-3B data return-ready, and produces e-way bills and e-invoices for both intra-state sales within Tamil Nadu and inter-state shipments. No add-on licence, no surprise fees.

Who this is for in Coimbatore — and who it isn't
A good fit
If you run a pumps, motors & wet grinders business in Coimbatore on a paper bill book, a spreadsheet or an old single-PC desktop package, 399Apps fits. GST billing, stock and outstanding move to the cloud, your team bills from any device, and the price stays flat at ₹399/month per app as you add staff.
Not a fit
If you need factory-floor manufacturing costing — bill of materials, multi-stage work-in-progress, machine-wise costing — or statutory payroll with PF, ESI and TDS filings, 399Apps does not cover that today. TallyPrime with add-ons, Marg ERP or an SAP Business One implementation is the honest recommendation there.
