Installing the TaskAutomate Tally Bridge: A 10-Minute Setup Guide for Indian SMBs

Before you start

The TaskAutomate Tally Bridge runs as a Windows service alongside Tally Prime. The full install takes under ten minutes if you have:

• A Windows 10, Windows 11, or Windows Server 2019+ machine on the same network as Tally
• Tally Prime or Tally ERP 9 with the HTTP-XML server enabled (most installations already have this)
• Your TaskAutomate organisation API key (we will show you where to find it)
• Administrator access to the Windows machine for the installer

No coding, no command line, no firewall changes needed.

Step 1 — Get your API key from TaskAutomate

Log in to TaskAutomate, then:

Open Settings → Integrations

Find the Tally Bridge card

Click Generate API key

Copy the key to your clipboard (it starts with `ta_org_`)

This key is organisation-scoped — it only grants the Bridge permission to fetch your organisation's approved vouchers. It cannot read invoices, change settings, or access user data.

Treat the key like a password. If you ever need to rotate it, click Generate API key again — the old key will stop working immediately.

Step 2 — Download the installer

In the same Integrations page, click Download Tally Bridge installer. You will get a signed Windows installer:

• File name: `TaskAutomateTallyBridge-Setup.exe`
• Size: ~15 MB
• Digital signature: TaskAutomate Technologies Pvt. Ltd.

Transfer the file to the Windows machine that will host the Bridge. The machine does not need to be the same one where Tally Prime is installed — only on the same local network as Tally.

Step 3 — Run the installer

Right-click the installer and choose Run as administrator. Inno Setup launches.

Screen	What to do
Welcome	Click Next
Licence	Read and accept
Install location	Default is `C:\Program Files\TaskAutomate\TallyBridge` — leave it
Components	All required components are selected by default
Configuration	This is the one you fill in — see below
Ready to install	Click Install

Step 4 — Fill in the configuration screen

This is the only screen where you enter information:

Field	What to enter	Default
Backend URL	`https://api.taskautomate.io`	Pre-filled
API key	Paste your `ta_org_...` key from Step 1	Empty
Tally host	`localhost` if Tally is on the same machine, otherwise the Tally machine's IP	`localhost`
Tally port	`9000`	`9000`
Poll interval (seconds)	How often the Bridge checks for new vouchers	`30`
Log level	`info` for normal use, `debug` for troubleshooting	`info`

Most setups can accept all the defaults and just paste the API key. Click Next, then Install.

The installer takes about 30 seconds. It registers the Bridge as a Windows service, starts it, and writes the configuration to `%PROGRAMDATA%\TaskAutomateTallyBridge\config.json`.

Step 5 — Confirm Tally is reachable

Before you post a real voucher, verify the Bridge can reach Tally:

Open Tally Prime

Make sure Gateway → Help → Settings → Advanced → Tally.ERP 9 to act as → Both is set (or in Tally Prime, F12 → Advanced → Use TallyPrime as a service = yes, with port 9000)

On the Bridge machine, open a browser and visit `http://localhost:9000` (or the Tally machine's IP)

You should see a Tally XML response. If yes, the Bridge can reach Tally.

If you get a connection error, Tally's XML server is not running. Open Tally Prime, enable the setting in step 2, and try again.

Step 6 — Post your first voucher

Back in TaskAutomate:

Upload a sample invoice

Let extraction complete

Click Approve

Watch the dashboard — within 30 seconds (the default poll interval), the status changes from "Queued for Tally" to "Posted to Tally".

Open Tally Prime, navigate to the Day Book, and confirm the voucher is there. Ledger, voucher type, GST tags — all in place.

If you do not see the voucher after 60 seconds, check the Bridge log at `%PROGRAMDATA%\TaskAutomateTallyBridge\logs\` for diagnostics.

Step 7 — Map your ledgers (one-time, in TaskAutomate)

The first voucher will use TaskAutomate's default ledger mapping (e.g., "Sundry Creditors", "CGST 9%", etc). To match your actual chart of accounts, go to: TaskAutomate → Settings → Tally Mappings

Map:

• Vendor → Sundry Creditor ledger (one row per vendor, or a default)
• Tax heads → Your CGST / SGST / IGST ledgers
• Expense ledgers → Per HSN code or per category
• Cost centres (optional)

You only do this once. Every future voucher uses these rules automatically.

Troubleshooting

"Tally not responding" in Bridge logs. Tally Prime is closed, or the XML server is disabled. Re-open Tally and check the F12 → Advanced setting. "401 Unauthorized" from the API. Your API key is wrong or has been rotated. Generate a fresh key in TaskAutomate Settings → Integrations and re-run the installer (or edit `config.json` directly and restart the service). Vouchers post but ledgers are wrong. Update your mappings in TaskAutomate → Settings → Tally Mappings. Existing vouchers are not retroactively re-posted; new vouchers will use the updated rules. Service is not running after reboot. Open `services.msc`, find TaskAutomate Tally Bridge, set Startup Type to Automatic, and click Start.
