Step 1 : Match numbers with tally.

Step 2 : If there's a difference in outstanding , Search for a particular ledger in which outstanding is not matching up.

Step 3 : Then sort the data month wise by going into the ledger report of that particular party.

Step 4 : Go month by month and match closing balance of a particular party , If you get to find a difference in any particular month then bifurcate it into day wise and find the difference amount

Step 5 : If there is some voucher missing then please check whether you have opened your company data from two different paths in tally.

Step 6 : If "YES" then avoid opening companies from 2 different paths and re-sync data from the Biz Analyst desktop app.

Step 7 : If you have not opened data from two path check whether desktop app is installed in 2 location/desktop with different versions. If "YES" please remove the other version and resync the data  (For agents: check in admin app If data is syncing form 2 different versions, if yes ask customer to uninstall one and use one app and resync data once) 

Step 8: If everything is fine but issue persists, check for one entry from a ledger which is missing from ledger report of mobile app but available in day book with small difference like change in voucher no, ledger name difference or no data found while opened.

Step 9: check for any previous tickets raised for same issue and if master name build was installed, If yes then check the desktop and re-install master build and resync data.
