# Lejur One

> Lejur One puts your Tally books on Claude and ChatGPT. A read-only Tally connector syncs your books to your own Lejur One workspace; then you ask about outstanding, sales, stock, profit or GST in Claude, ChatGPT or Perplexity, or in Lejurly, the chat inside the app, on your laptop or your phone.

Built by a CA practice, for businesses in India that keep their books in TallyPrime, and for the accountants who look after them.

## Your Tally books on Claude and ChatGPT

- Ask in plain language and get the answer from your synced Tally books: outstanding, sales, stock, profit, GST.
- Build MIS in seconds, draft replies to GST notices, and research any party's history.
- Example: "Which customers are overdue beyond 90 days?"
- Connect once: add https://app.lejur.one/mcp as a connector in Claude, ChatGPT or any other MCP (Model Context Protocol) client, sign in to Lejur One, review the companies it will read, and approve. There is no API key to copy.
- Standard finance reports the assistant can run: profit and loss, balance sheet, trial balance, profit and revenue trends, expense breakdown, cash position and monthly cash flow, working capital, receivables and payables ageing, receivables by customer, debtor days, unapplied receipts, payables by supplier, customer concentration, supplier spend, cost-centre spend, GST summary, GSTR-2B reconciliation, ITC at risk, largest transactions, ledger statements, day book, stock summary, item movement and stock drift.
- For anything the reports do not cover, the assistant can write its own read-only query over the same books, and a data-health check tells it which periods have been synced before it draws conclusions.
- Read-only by design, enforced in the database: nothing an assistant does can change your books.
- Prefer to stay in the app? Ask Lejurly, the chat inside Lejur One.

## Tally on your phone

- The Lejur One mobile app, unlocked with your MPIN or biometrics.
- Dashboard, ledgers with voucher drill-down, reports (profit and loss, balance sheet, by cost centre), receivables and payables ageing, and the GSTR-2B reconciliation.

## Reports in the web app

- Trial Balance, Schedule III Profit and Loss and Balance Sheet.
- Receivables and payables ageing, ledger report, day book.
- GSTR-2B reconciliation of purchases against your books.
- Stock: inventory ledger and stock by godown.
- Cost centres, chart of accounts and parties, as they are in Tally.

## The Tally connector

- Runs on the computer TallyPrime runs on, as a Chrome extension or a desktop app for Windows.
- It can only read: nothing in your books can be created, changed or deleted.
- Ledgers, vouchers, stock items and cost centres go to your own Lejur One workspace, and nowhere else.

## Privacy and teams

- Sealed companies (optional, Settings > Privacy): party names, GSTINs, narrations and other identity fields are stored encrypted under a key the server holds only while a member has Lejur One open and unlocked with the vault passphrase. Turned on before the first company is added. AI access stays on; for a sealed organisation the assistant and Tally sync can read the books only while a Lejur tab holds the vault open.
- Team access: invite people to a company as owner, accountant or viewer.
