A GST invoice should take seconds, not a form tour
Billing is the thing you do a hundred times a day, so it is the thing that should cost you the least. Acronix resolves the tax treatment from the data it already has and gets out of the way.
- Auto CGST/SGST/IGST
- HSN on the item
- Tax-invoice print
- Keyboard-first
- E-invoice ready
Where this usually goes wrong
CGST/SGST vs IGST decided by hand
Intra- or inter-state is a function of two state codes. Deciding it per invoice is a mistake waiting to be replicated.
Rates re-chosen on every voucher
When the rate is a per-line decision rather than a property of the product, two operators will eventually disagree.
Invoices re-typed into a portal
E-invoicing turns into duplicate data entry the moment the billing system and the IRP are not fed by the same voucher.
How it works in the app you can download
Every capability below ships in the current build.
Place of supply drives the tax split
The company state code and the party state code decide CGST+SGST versus IGST automatically. It is derived, not typed.
Tax categories on the item master
Rate and HSN belong to the product, so they travel onto every voucher line the same way every time — and HSN summaries fall out of the same data.
Fully keyboard-driven entry
Function keys per module, Enter to advance, Ctrl+K for anything. The app targets sub-200ms on common actions.
Tax-invoice print and Save & Print
Print a compliant tax invoice straight from the voucher — including a Save & Print in one keystroke (Ctrl+Shift+P).
One voucher, many outputs
The same sale feeds the ledger, stock, the bill, GSTR-1, the HSN summary, e-invoice and the e-way bill. Nothing is entered twice.
Posted invoices are immutable
A posted voucher never mutates. Corrections happen through reversals, so the audit trail stays honest.

Questions
GST Billing & Invoicing — questions, answered
Straight answers on what's in the current build and what it does not do.
How does Acronix decide between CGST/SGST and IGST on an invoice?
It derives the split from two state codes — your company state and the party place of supply. When they match it posts CGST plus SGST; when they differ it posts IGST. You never pick the treatment per invoice, so two operators cannot quietly disagree on the same customer.
Do I have to re-select the tax rate and HSN on every line?
No. Rate and HSN are properties of the item on its master, so they travel onto every voucher line the same way each time. The same item data also feeds the HSN summary your return needs, so nothing is entered a second time.
Can I print a compliant tax invoice straight from the voucher?
Yes. You print a tax invoice directly from the sale voucher, and Save & Print posts and prints in one keystroke (Ctrl+Shift+P) so counter billing stays a single motion rather than a save-then-hunt-for-print sequence.
Can I raise the e-invoice and e-way bill from the same sale?
Yes. One sale voucher feeds the ledger, stock, the bill, GSTR-1, the HSN summary, the e-invoice (IRN) payload and the e-way bill payload. The invoice is entered once and every downstream document is built from it.
How fast is billing, and does it need a mouse?
The app is fully keyboard-driven — function keys per module, Enter to advance a field, Ctrl+K for anything — and targets sub-200ms on common actions. It is built for someone raising a hundred invoices a day, not for a demo.
Can a posted invoice be edited afterwards?
A posted voucher is immutable. Corrections happen through reversal vouchers rather than a silent edit, so the invoice you printed and the entry in the books can never drift apart and the audit trail stays honest.
