Every rupee your business moves, in one ledger.
Invoicing, purchases, banking, inventory, payroll and GST returns — one double-entry system that keeps your books closing-ready instead of month-end-ready.
Books in one tool. GST in another.
The truth in a spreadsheet.
Most growing businesses run accounting across four disconnected places — and pay for it at every deadline.
Same data, entered three times
An invoice typed into the billing app, again into the books, again into a stock sheet. Nothing agrees, and reconciling becomes somebody's whole week.
Deadlines found out late
GSTR-1, 2B, 3B, e-invoicing, e-way bills, TDS. One missed reminder becomes a late fee, then a notice, then an evening with your CA.
Numbers you can't act on
By the time the books close, the month is gone. Margin, cash position and receivables are history instead of decisions.
A real ledger underneath. Compliance on top.
Accountieons is not a billing app with a GST report bolted on. Every document posts to a double-entry ledger, and the returns are generated from that same ledger.
Books that stay audit-ready
Chart of accounts, journals, cost centres, period locking and multi-currency — the accounting layer your CA expects to find.
- True double-entry — every invoice, bill, payment and payroll run posts itself.
- Bank reconciliation — import a statement, auto-match against open items.
- Period locking & audit trail — closed months stay closed, changes stay traceable.
- Multi-company, multi-branch — consolidated or standalone, one login.
GST that files from your books
Place of supply, CGST/SGST vs IGST, HSN summaries and reverse charge are decided at entry — so the return is a review, not a rebuild.
- GSTR-1, 2A/2B, 3B — generated, reconciled and diffed against your ledger.
- Place of supply, automatic — CGST + SGST or IGST decided per document, not by hand.
- TDS & TCS — tracked per vendor and section, ready for the quarterly return.
- Deadline board — every due date per company, counted down and assigned.
The whole back office, nothing bolted on.
Turn on what you need. Each module writes to the same ledger, so a sale becomes stock movement becomes a GST line becomes a receipt — without a copy-paste.

What changes in week one.
Before
- Invoices typed twice — once to bill, once to book
- Bank statement reconciled by eye, line by line
- GSTR-2B mismatches found on the filing date
- Stock value guessed until the physical count
- Margin known three weeks after the month ends
With Accountieons
- One entry posts the invoice, the tax and the ledger
- Statement auto-matched, exceptions in a short queue
- 2B reconciled continuously, mismatches assigned
- Live stock valuation feeding cost of goods sold
- Margin per invoice, visible before you send it

Plugs into what you already run.
Payments, messaging, sales channels and the GST network — plus an open API when you need your own.
We were billing in one app and booking in another, reconciling both at month-end. Accountieons put them in the same ledger — GSTR-3B now takes an afternoon instead of a week, and nobody hunts for a bill anymore.
The things businesses ask us first.
Every document is taxed at entry based on place of supply, so GSTR-1, 2A/2B and 3B are generated from your ledger rather than rebuilt, and TDS and TCS are tracked alongside. We do not generate e-invoices (IRN) or e-way bills yet — raise those on the government portal alongside Accountieons.
Yes. Each company is an isolated set of books with its own registration, users and documents, plus consolidated reporting across the group. CA and tax firms use the same structure to keep every client separate.
You start from a clean cut-off. We configure your entities, tax registrations and templates, then set up opening balances, outstanding invoices and stock with your team so the first period begins accurate. Your old records stay where they are as an archive.
Most businesses are billing from Accountieons within a week — discovery call, configuration, opening balances and two training sessions, all done by our team, with a shared support group for your staff.
Yes — invite them as a scoped user. They see the books and returns they need, permissions stop where you decide, and every action they take is in the audit log.
