Tds deduction

Dear Experts,

I have confusion w.r.t. TDS deduction.

Scenario: Say for example vendors provides services for Apr-Jun and raises invoices only on Dec having invoice dated end of June.....

1. When to do booking of invoice?

2. If invoices is booked on receipt date and not on invoice date when to deduct TDS?

3. If monthly provision is done from Apr to June when to deduct TDS?

Request you to please provide me your valuable reply.

Thanks, Himanshu Dave
