The Desktop App works like a bridge between your
Tally ERP and TallyDekho mobile App on your phone. Desktop App
extracts tally data from your system and saves it as encrypted file
on your google drive linked to your account and generates QR code
for the mobile App to get connected.
No, you should start TallyDekho when you start
Tally ERP. You can set time interval like in every two hours to sync
your data to Google Drive. You can also chose to sync it manually.
For that you should open TallyDekho App whenever you want and click
on sync button in the app. It generally takes 5-10 minutes to upload
data on google drive. Please make sure Tally ERP is open when data
is being synced.
