Turning on connectivity in Tally

The step people miss: opening port 9000 so Tally will answer at all.

Tally does not answer outside requests until you tell it to. This is the step most people miss, and the cause of most "Tally not reachable" messages.

Switch it on

In Tally Prime, with your company open:

  1. Press F1, then choose Settings

    From anywhere in Tally.

  2. Open Connectivity

  3. Set TallyPrime acts as to Both

    Under Client/Server configuration. Both means Tally will answer requests as well as make them.

  4. Set Enable ODBC to Yes

    This is the setting that opens the port. Older material, and the Connector's own on-screen note, call it Enable HTTP XML — TallyPrime labels it ODBC, and it is the same row.

  5. Check the port reads 9000

    The default, and what the Connector expects.

  6. Accept the screen

    Tally applies it immediately. No restart needed.

TallyPrime's Client/Server configuration, with TallyPrime acts as set to Both, Enable ODBC set to Yes and the port reading 9000
Tally's own screen, not OptiVida's. These three settings are what the Connector needs.

On an older build

Some Tally ERP 9 builds put this under F12Advanced Configuration rather than under F1. The three settings are the same.

Confirm it worked

Open the Connector from the notification area. Its Tally card should now name your open company. If it does not, use Test the connection on the Tally settings tab — that pings Tally there and then, rather than waiting for the background check.

Three things that stop it

Tally is not open

Or is open with no company loaded. Both look the same from outside.

Something else holds port 9000

Another Tally instance is the usual culprit. Only one can hold the port.

Tally is on a different machine

The Connector reads Tally locally. It cannot reach a Tally across the network or on a server.

Warning

Tally must be open with the right company loaded at the moment you fetch, not merely at the moment you set this up. A fetch against a closed Tally, or one showing a different company, will not quietly use stale figures — it will tell you.

Tip

Next: Pairing your device. If Tally still will not answer, see OptiVida cannot reach Tally.
