Your Tally. On Your Mobile.
In 10 Minutes.
You don't need to be an IT expert. If you know how to install WhatsApp, you know how to set up Accosync.
Install the PC Connector
~3 minSecurely download our lightweight connector software directly onto the Windows computer where your Tally ERP 9 or Tally Prime is running. You'll see a small system-tray icon confirming it's installed and running.
Link Your Tally Data
~1 minThe connector automatically detects your active Tally instance. Open the connector, authorize via secure OTP sent to your mobile, and tick the companies you want to sync — you can select one or several. The initial encrypted handshake completes in under a minute, and you'll see each selected company listed as "Connected" in the connector window.
Download the App
~2 minSearch for "Accosync" on the Google Play Store (Android) or the App Store (iPhone/iPad), or use the direct download links on our download page. Open the app and log in with the same mobile number you used to authorize the connector.
Access Your Live Data
InstantOnce logged in, your connected companies appear immediately with live sales, outstanding, and stock reports — no manual refresh needed. Every new Tally entry reflects on the app within seconds of being saved.
Add Your Team (Optional)
~2 minGoing beyond solo use? Within your Accosync app settings, invite your sales agent or HR manager by mobile number, setting restrictive view-only permissions instantly. They see only what you allow.
Common Setup Issues
Tally integration port is closed
Ensure Tally ODBC server is enabled: in Tally, go to F12 (Configuration) → Advanced Configuration → Enable ODBC Server. Set the port to the default (9000) unless your network requires otherwise, then restart Tally before reconnecting.
Connector displays "Waiting for connection"
Ensure your Windows Defender Firewall (or third-party antivirus) is not blocking the Accosync executable. Add an inbound/outbound rule allowing the connector, or temporarily disable the firewall to confirm it's the cause before re-enabling it with an exception.
Mobile app shows no data after login
Confirm the PC connector is still running (check the system tray icon) and that the correct company is ticked as "Connected." If the PC has gone to sleep or lost internet access, the connector pauses syncing until the PC is active online again.
OTP not received during setup
Double-check the mobile number entered matches exactly, wait up to 60 seconds before requesting a resend, and confirm the number isn't blocking DLT-registered SMS senders (common with some telecom spam filters).
