Ledger Shield is a Windows app for CA firms and businesses on TallyPrime. It gives you a live dashboard and Tally-style reports with Excel export, and connects AI apps like Claude to your books through a local MCP server that masks personal data before anything reaches the AI model. Everything runs on your own computer.
Sales, margin, cash and bank balances, receivables and payables ageing, and your GST position — read straight from TallyPrime, so you see where the business stands without building reports by hand.
Day Book, ledgers, trial balance, profit & loss and balance sheet in a familiar layout, with one-click Excel export for working papers and client packs.
A local MCP server lets AI apps such as Claude Desktop read your books. Names of individuals and proprietors become tokens like PERSON_0001, and PAN, Aadhaar, phone, e-mail, UPI IDs and bank account numbers are redacted before anything reaches the AI model.
Ledger Shield records what was shared with AI apps in a disclosure log, and scan-transcripts checks saved AI conversations — so you can show what left your books and what didn't.
Vouchers, GST invoices and masters prepared through AI are posted to TallyPrime only after a draft is shown to you and you confirm it.
Form 3CD working papers clause by clause, with an Excel workbook, plus GST tools: GST summary, GST invoices and item GST masters.
Every licence runs for one year from issue. The app includes a 3-day free trial with Pro features for one company. Use is subject to the Ledger Shield End User Licence Agreement.
Ledger Shield runs entirely on your own Windows computer and talks to TallyPrime locally. Your Tally data never goes to Authentic Technologies — the app only contacts our server to activate and check your licence. AI features use the AI app you choose, on your own plan, and only ever receive masked data.
Ledger Shield is built with our best efforts to help you meet your obligations under India's Digital Personal Data Protection Act, 2023: personal data in your books is masked before it reaches an AI model. It does not by itself make you DPDP compliant, and we don't guarantee any compliance outcome — compliance remains your responsibility as the data fiduciary.
Download LedgerShield-Setup.exe and run the installer. The app starts a 3-day free trial with Pro features for one company.
Enable TallyPrime's XML server (F1 › Settings › Connectivity, port 9000) and Ledger Shield reads your companies directly.
Pay by UPI on the buy page. Once payment is verified your LSHD licence key and GST invoice arrive by email — paste the key on the Licence page in the app and click Activate.
Open Connect AI apps in Ledger Shield to link Claude Desktop (or another MCP-capable AI app) to your masked books.
Full setup steps are in the instructions.
Ledger Shield is a Windows app from Authentic Technologies for CA firms and businesses that use TallyPrime. It shows a live dashboard and Tally-style reports with Excel export, and lets AI apps such as Claude read the books through a local MCP server that masks personal data first.
No. Ledger Shield runs on your own computer and reads TallyPrime locally, so your Tally data never goes to Authentic Technologies. When you use AI features, the AI app you connect receives only masked data: names of individuals and proprietors become tokens like PERSON_0001, and PAN, Aadhaar, phone, e-mail, UPI IDs and bank account numbers are redacted.
No software can do that on its own. Ledger Shield is built with our best efforts to help you meet your obligations under India's Digital Personal Data Protection Act, 2023: personal data in your books is masked before it reaches an AI model. It does not by itself make you DPDP compliant, and we don't guarantee any compliance outcome — compliance remains your responsibility as the data fiduciary.
Ledger Shield is a yearly licence with three plans: Pro at ₹2,999 plus GST (1 machine, 2 Tally companies), Advanced at ₹8,999 plus GST (2 machines, 5 companies) and Team at ₹14,999 plus GST (5 machines, unlimited companies). The app includes a 3-day free trial.
Yes, on the Advanced and Team plans. Vouchers, GST invoices and masters prepared through AI are shown to you as a draft and posted to TallyPrime only after you confirm. The Pro plan gives AI apps masked read access to the books.
Ledger Shield needs Windows 10 or 11 (64-bit), TallyPrime with the XML server enabled on port 9000, and an internet connection once to activate the licence. AI features also need an AI app that supports MCP, such as Claude Desktop, on your own plan.
