Accounting/ bookkeeping fees

Always advisable to take fees on monthly basis ( within 5 days from end of the month: similar to how salary payments are processed ). Normally, it depends on quantum, days involved and client specific requirements.

Normally take up all compliance work at a fixed monthly cost. Regular payments is a key to sustainable business definitely.

If it's on the basis of retainer we can proceed as per months fees.
In case it's a contractual one Sec 194J is applicable.
