Smart Accounting & Finance Management System
Accounting, GST Billing & Business Management Software
AXPERTZ GST PRO brings accounting, GST billing and day-to-day business management together. It is local-first: your books stay in a database on your own computer, not on our servers. It produces GST-compliant invoices, keeps stock in step with billing, and maintains the transaction detail your returns are prepared from. It does not file returns on the government portal for you — it keeps the underlying records correct and ready.
Key benefits
Invoice formats and tax treatment follow GST rules instead of being patched together.
Transaction data stays organised through the year, not rebuilt in the last week.
Consistent GSTIN, HSN and tax details reduce corrections and credit notes.
Core features
The capabilities AXPERTZ GST PRO ships with.
Tax invoices, bills of supply, credit and debit notes with correct tax breakup.
Store IRN and e-way bill details against the transaction they belong to. Record-keeping only — generation on the government portal is not included.
Maintain item-wise HSN codes and tax rates so billing stays consistent.
Customer and supplier records with GSTIN, place of supply and contact details.
Outward and inward summaries organised for handover to your filing process.
Track billed items and stock movement alongside your invoices.
AXPERTZ GST PRO automatically creates recovery backups on your computer so you can restore your accounting data if the active database is accidentally deleted or becomes corrupted.
How it works
Add your GSTIN, place of supply, invoice series and tax preferences.
Raise GST invoices with the right tax treatment applied automatically.
e-Invoice, e-way bill and payment details stay linked to each transaction.

Check this before you download. Not every part of this software is equally demanding, so each part is listed separately with what it actually needs.
Billing, accounting, stock and returns data — all of it on one ordinary computer.

Your books live in a database on this computer, so keep free space for them and for the automatic local backups. No internet connection is needed for day-to-day work.
Windows shows a warning before the first launch of software it has not seen before. It is about how many people have installed the file so far, not about what is in it — and it is the same warning every new application gets, from every publisher, on its first day.
You do not have to take our word for it. Every download on this page carries its SHA-256 — a fingerprint of the exact file we published. Run the one command below and compare: if it matches, what reached your computer is byte-for-byte what left ours, and nothing altered it on the way.
Windows judges an installer partly by how many people have run it. A newly published version starts at nothing and earns that quietly, so the panel can appear again after an update even though nothing about the software changed.
To check the file first, in PowerShell:
Get-FileHash .\AXPERTZ-GST-PRO-1.0.1-Windows-setup.exe -Algorithm SHA256
