GST billing software

GST billing software built for the 2.0 slab structure

filarity issues GST invoices with CGST and SGST for sales inside your state, IGST for other states, and an HSN code per product. Rates follow the GST 2.0 structure of 0%, 5%, 18% and 40% in force from 22 September 2025. Non-GST businesses get clean invoices with no tax columns.

The rates it works to

GST 2.0 replaced the old four slabs on 22 September 2025. The 12% and 28% slabs were abolished, most goods moved to 5% or 18%, and a 40% slab was introduced for luxury and sin goods. GST rate is a per-product field, so a catalogue still carrying 12% or 28% is a filter away from being corrected.

  • 0% - essentials including dairy, life-saving medicines and educational material
  • 5% - daily essentials, packaged foods, FMCG and toiletries
  • 18% - most goods and services
  • 40% - luxury and sin goods

How the tax splits on an invoice

Place of supply decides the split, and filarity applies it from the customer record rather than asking the person at the counter to remember.

Inside your state

The tax splits into CGST and SGST at half the slab rate each, shown as separate lines on the invoice.

To another state

IGST applies at the full slab rate as a single line.

Not GST registered

Invoices render with no tax columns at all. Switch GST on later from Settings and existing invoice templates change automatically.

What happens after the invoice is raised

Billing is only useful if the invoice reaches the customer the way they actually receive things.

  • Live preview beside the entry form, so errors are caught before printing
  • Print, or download a per-invoice PDF
  • Send to WhatsApp as a chat with the invoice summary
  • Barcode scanning at the counter for both billing and stock receiving
  • Excel export of any filtered invoice list for your accountant

What it does not do

Two honest limits, because finding them out in month two is worse than reading them here. filarity does not generate e-way bills, and it does not report invoices to the Invoice Registration Portal for an IRN. If your turnover puts you inside the e-invoicing mandate, or you move goods that need e-way bills daily, confirm your route for those before switching.

Billing is the input, not the point

Every GST invoice raised in filarity carries the cost price of what was sold, so the same act that satisfies compliance also builds the profit figure. That is the difference between billing software and a profit system: the invoice is the input either way, but only one of them tells you what you kept.
