Need clarification on tds deduction and tds payment

Dear All,

This is Prasad A. My query is We are paying commission to my customers on weekly basis. for that we need to deduct TDS on commission, my problem is here only that is if customer got more than 5,000/- commission we deduct 10% TDS and we paid remaining amount but some customers got 3,000/- in this week again same person got 4,000/- in next month, for this how should I deduct TDS for second person?.
