Getting started

A five-minute tour of Acronix Books — what it is, how it's built, and the fastest path from download to your first invoice.

Acronix Books is a modern ERP and accounting desktop app for Indian businesses of every size. It runs entirely on your own computer, works offline, and is built to be fast and keyboard-driven — while staying GST-ready out of the box.

This guide gives you the lay of the land. If you just want to get going, jump straight to Installation.

What you get

  • Accounting — multi-company books, ledgers, account groups and ten voucher types (sale, purchase, receipt, payment, contra, journal, credit note, debit note, delivery challan and stock journal) through one shared posting engine.
  • GST — tax categories and HSN codes on every item, the tax registers and HSN summary, GSTR-1 and GSTR-3B with Excel export, plus e-invoice and e-way bill generation.
  • Inventory — items, item groups, units, tax categories, warehouses, weighted-average / FIFO valuation, delivery challans, stock journals and job-work rates.
  • Reports — day book, trial balance, P&L and balance sheet (both drillable), cash flow, outstandings and stock reports, all exportable to PDF and Excel.
  • Security — your entire book is encrypted at rest with SQLCipher AES-256, protected by encrypted login, RBAC roles, idle auto-lock and a tamper-evident audit trail.
  • Cloud sync (optional) — back up your whole book to your own isolated, encrypted cloud space and restore it on a new device.

How it's different

Offline-first, by design

Acronix Books stores your data locally and works with zero internet connection. Cloud sync is entirely optional and something you turn on when you want it — your books are never held hostage by a network outage or a lapsed subscription.

Because everything runs locally, interactions are near-instant. Lists are virtualized, so a company with 50,000+ vouchers in a financial year stays responsive. And almost every action has a keyboard shortcut, so data entry is fast once the workflow is in your fingers.

The fastest path to your first invoice

  1. Download and install the Windows app.
  2. Create your first company and set the financial year (April–March).
  3. Set up GST — your GSTIN, tax categories and HSN codes.
  4. Create a sales voucher — see Invoicing & vouchers.
