Frequently Asked Questions

Yes! The Accosync Connector works with all versions of TallyPrime (1.0 to 5.0+) as well as Tally ERP 9 (Release 4.5 and above).

For live synchronization, your Tally PC needs to be powered on and connected to the internet. If the PC is turned off, you can still view your previously synced data on the mobile app, and new changes sync as soon as the PC is back on.

No. Accosync uses bank-grade end-to-end encryption. Your accounting numbers and ledgers stay securely on your PC and mobile device. We never store or sell your private accounting databases.

Choose 64-bit if your computer was bought after 2010 or runs Windows 10/11 (over 95% of PCs). Choose 32-bit only if you are on an older legacy 32-bit Windows system.

You can upgrade to our very affordable flat annual plan. If you choose not to subscribe, your trial ends with zero commitments or hidden charges — and your Tally data on your PC is 100% untouched.
