AIBI by Fawn Technologies

GST-Ready Accounting for Indian Business

The books of your business, kept the way you'd keep them yourself.

AIBI is a complete, Tally-style accounting desktop application built for Indian traders, manufacturers, and service businesses — full double-entry bookkeeping and GST compliance, encrypted and stored entirely on your own computer, simple enough to hand to someone who has never used accounting software.

Built for three kinds of business

Whatever you sell, AIBI keeps the entry correct.

Most accounting software is designed for one kind of business and bent to fit the rest. AIBI's voucher and inventory model was built to genuinely cover all three.

Traders

Buy, sell, and stay GST-correct

Sales and Purchase vouchers with automatic CGST/SGST/IGST calculation, stock tracking, and every GST return your business needs to file — GSTR-1, GSTR-3B, and Input Tax Credit, without hiring a specialist to operate the software.

Manufacturers

Know what a finished good actually costs

Define a Bill of Materials once, then record production runs where the raw-material consumption, weighted-average costing, and stock movement are all calculated for you — not tracked separately in a spreadsheet on the side.

Service businesses

Bill without the clutter of items you don't stock

Accounting Invoice mode drops the item-line table entirely for a business that bills for services, not goods — the same GST-correct posting underneath, a simpler form on top.

The case for switching

Four things AIBI won't compromise on.

1

Complete books, free — permanently

Full double-entry accounting, every GST report, multi-company support, and encrypted manual backups are not a trial. They're the free tier, for as long as you use AIBI.

2

Records that can prove they weren't touched

Every voucher is cryptographically chained to the one before it. If a row is ever altered outside the application, AIBI can show exactly that — the same trust a physical ledger earns from being hard to fake, backed by cryptography instead of habit.

3

Your machine, your data

AIBI is not a monthly cloud subscription for the basics. Your books are encrypted and stored on your own computer. You choose if, when, and where a backup leaves it.

4

One admin, every company

Run two businesses, or ten. One installation, one login, one license — a picker switches between fully separate, independently encrypted company books in a click.

Inside the ledger

What's actually in the box.

Not a features list padded for length — every line below is a real, working part of AIBI today. Deeper, Tally-parity features stay tucked away until you actually flip them on in Settings — so the app you open on day one is never more cluttered than the business you're running that day.

Core accounting & GST Free
10 voucher types
Sales, Purchase, Receipt, Payment, Contra, Journal, Debit Note, Credit Note, GST Payment, TCS Payment — each auto-numbered, each fully keyboard-operable.
Switch from Tally — with your full history intact
Bring across your chart of accounts, stock items, and every historical voucher — not just current balances. Your books stay one continuous, tamper-evident record from before the switch to after it.
Trade Discount
Per-item, scheduled, or whole-invoice discounts — stack them freely, and a printed invoice shows exactly what was taken off.
Get paid faster with UPI
Add your UPI ID once; every printed invoice carries a Scan to Pay QR code. No merchant account, no transaction fee, no middleman — your customer pays you directly.
Credit limits & bill-wise tracking
Set how much — and how long — a customer can owe before AIBI warns you at the point of sale. Turn on bill-wise tracking and every receipt matches against the specific invoice it settles, with real per-bill ageing.
GST Summary, GSTR-1, GSTR-3B, ITC
The four returns a filing actually needs, computed live from your vouchers — not a separate reconciliation exercise.
GSTR-2A/2B Reconciliation
Upload what the GST portal says your suppliers filed; AIBI matches it against your own purchase register and flags exactly where Input Tax Credit is at risk.
Trial Balance, P&L, Balance Sheet, Day Book
Standard financial reports with a built-in self-check that catches an out-of-balance sheet before your CA does.
Business Snapshot
A plain-language summary — no accounting background required — exportable as CSV, JSON, or a clean PDF for handing straight to your CA.
Cost Centers
See exactly which department or project a rupee of income or expense belongs to — nested, Tally-style, and splittable across more than one at once — without keeping a second set of books.
Trade-ins, done right
A customer hands over an old item as part of the sale — jewellery exchange, an old phone, anything. GST stays correct on the full sale value; your customer only ever owes the difference.
Making charges, priced separately
Add a making charge, packing fee, or service charge to any item — taxed at its own GST rate if it needs one, shown transparently on the printed bill, not buried inside the item's own price.
Budget against real numbers
Set what each income or expense ledger should hit, month by month — see the actual variance live, not at month-end.
Prints on your own letterhead
Already have printed stationery? AIBI fits its invoice into the blank space, margins and all — no duplicate header fighting with your own.
Back up every company in one file
Running more than one business? Back all of them up together, under one passphrase — restore any one of them, or all of them, on any machine.
Inventory & manufacturing Free
Stock & Units of Measure
Item master with low-stock alerts, compound units (a Box of 12 Pcs), and CSV bulk import for a fast initial setup.
Rate Groups for shared, daily-changing prices
A jeweller's daily gold rate, or any commodity priced the same way — update it once and every item tagged to it reprices instantly, with a dated history and trend chart.
Stock Groups
Organize items into nested groups — Electronics under Hardware — the same way you already think about your own shelves.
Godowns & Stock Transfer
Track stock across more than one location — a warehouse and a shop counter — and move it between them cleanly, with a full transfer history.
Bill of Materials & Production Journal
Define a recipe once; every production run afterward auto-calculates component consumption and finished-goods cost.
Sales & Purchase Orders
Track a commitment before it's a bill — converts into a real invoice with one click when it's ready.
Growing with your business Pro
Payroll
Salary structures, automatic PF/ESI/TDS calculation, and printable salary slips.
Bank Reconciliation
Match your books against your bank statement with a proper BRS report.
TDS
Section-wise deduction tracking and Form 26Q data, ready to export.
TCS
AIBI suggests collecting Tax Collected at Source the moment a buyer's purchases actually cross the legal threshold — never an automatic silent charge — and tracks what's collected but not yet paid over.
Multi-user, multi-machine (LAN)
Your team works from more than one computer on the same network, on the same books, at the same time.
AI Assistant
Ask a question about your business in plain language — answered from your real ledgers and stock, not a generic chatbot.

The part software vendors gloss over

Trust isn't a feature. It's the whole point.

AIBI's stated bar for itself: earn the same trust a business puts in a physical ledger book — or more.

🔒

Encrypted at rest, always

Every company's data is individually encrypted on disk. The encryption key itself is locked to your specific Windows account — a copied file is unreadable anywhere else.

✓

Tamper-evident, by design

Each voucher is cryptographically linked to the one before it. A single "Verify" click confirms a record hasn't been altered since the day it was posted.

⇩

Backups that travel safely

An encrypted export can be restored on any machine, protected by a passphrase only you hold — your data outlives any single computer.
