Connect Tally as a data source

The ThynkTax Tally Connector pulls ledger, voucher, and master data from your client's Tally instance via the TDL (Tally Definition Language) framework.

Prerequisites

• Tally Prime (latest release recommended) running on the client's machine or server
• The machine must allow inbound connections from your network (typically port 9000)
• A static IP or VPN for production use

Installation

1. Download the connector from thynktax.com/desktop-download.
2. Install on the same machine as Tally (or on a server with TCP access to Tally on port 9000).
3. Run thynktax-tally-connect --setup - enter your workspace token and the client GSTIN.
4. The connector registers a TDL file with Tally and starts the sync service.

What syncs

• Sales & purchase vouchers - pushed to ThynkTax for GST reconciliation and ITR
• Ledger entries - for TDS deduction matching
• Bank reconciliation - for ITR bank-vs-ledger
• Inventory movements - for HSN summary in GSTR-1 / GSTR-9
• Trial balance - at month-end for ROC / financial statement prep

Sync frequency

• Real-time - for accepted invoices (push on save)
• Hourly - for everything else
• Manual - Settings → Integrations → Tally → Sync now

Security

• All sync traffic is TLS-encrypted
• The connector signs each payload with the workspace token
• ThynkTax never stores Tally credentials - the connector reads directly from Tally and pushes data outbound
