Tally

Step - 1

Accrual Entry to be passed in the month of Jan 2015 for expenses

Gateway of Tally -> Accounting Vouchers -> F7 and pass below entry

Step - 2

Payment Entry to be passed in the month of Feb 2015 for payment

Gateway of Tally -> Accounting Vouchers -> F5 and pass below entry

Hope this will help out.

If you have to pass outstanding expense entry at the month end entry would be like :

Press "F7" - Journal entry

i) If salary is payable

on 31/01/2015

Salary A/c will be debit           20,000

            To Salary Payable                      20,000

(Being salary payable for the month of Jan'15 to XXX)

Like this you can pass other outstanding entry.
