Drawn on the demo books of Acme Manufacturing — an illustration, not a customer's figures.
Every bank line read. Every entry written. Every figure checked twice. Before your morning chai.
What happens while you are asleep
- 01 / 05
It reads.
Bank messages, statements, supplier bills and your GSTR-2B arrive overnight. Every line is fingerprinted, so the same statement uploaded twice books nothing twice.
- 02 / 05
It matches.
Receipts find their invoices and payments find their bills — including a payment short by exactly the customer's TDS.
- 03 / 05
It books.
What a trusted rule covers is posted, in the name of the person who trusted it. Anything no rule covers is drafted for a person instead.
- 04 / 05
It flags.
A duplicate bill. A supplier whose bank account changed overnight. An MSME payment running late. Raised the night it appears, not at audit.
- 05 / 05
It checks.
An Inspector re-performs the whole night from the evidence, by a different path than the one that wrote it — and disagrees to the paisa when anything is off.

Inspector agreed
Software does not get to post on day one.
Every rule starts by watching. It earns the right to write, then the right to post, from a person who watched it get the same thing right ten times in a row. One reversal takes that right away — and an Inspector checks all of it, every night, by a different path.

It can post nothing and change nothing. The disagreement is now a flag on the morning review.
By morning, one screen.
Flags first, then what posted itself, then drafts, then whatever nothing covered. Your accountant reviews, signs off, and gets on with the day.
Figures for FY 2026-27, read from the same rule set the public checker and every client dashboard run on.
The work that only matters in India.
Foreign accounting software has no idea what input credit is, what a TDS section does, or why paying a small supplier late costs you a deduction. This was built here, by people who file it.
01
Input credit that would have expired
Your GSTR-2B against your purchase register, invoice by invoice, every month. A supplier who has not filed costs you real cash — and you find out while you can still act.

TDS, as a system rather than a scramble
Every payment watched against its section and its threshold, with the rates coming from your CA's own masters — never from us.

The MSME payment clock
A late payment to a small supplier is disallowed as an expense. The clock starts on the bill and runs to the limit you set, and it is flagged before it costs you.

A posted entry cannot be edited or deleted by anyone. Corrections are contra entries, closed periods refuse new ones, and every document keeps its fingerprint.

Every client's morning, on one screen.
If you are the CA, not the client: the typing, matching and chasing your juniors do by hand is what the night shift removes. What is left is review, judgement and the relationship.
