Pay salary to employees on first of every month - what are the things need to consider?

If any company want to pay salary to employees on first of every month what are the things need to consider & how i have lot of confusion as if i pay on 1st i have to be ready with everything on 29 or 30 but then how it is possible.. please guide..

if the salary is on monthly basis and absents are not deducted from salary but used to be adjusted in leave or alternate day work, it is very much possible
company pays the full salary ( exceptional is long term leave without payment which is well in knowledge of HR team) without any LOP so in such company it is always possible, if there is any shortage the same is adjusted from EL/CL or other means

Dear Komal
You can make payment of wages for actual attendance from 1st to 20th of each month and for 21st to 31/31st you can consider notional presence for every one and can make payroll run and disburse wages on 1st of subsequent month.
In coming month you can adjust any unauthorized leave (absence for which leave has not been applied/sanctioned)
Hope this works for you

For payroll purposes,consider your month 26th to 25th of following month.
Then it will be possible for making payment on 1st of following month.
