Tds Deduction

hello buddies,

i have question to ask.

We are having  warehouse agreements with a partticular CFA, and we are paying commission on sales and reimbursement of expenses which they are incurring on behalf of our company. Right now we are deducting TDS as Commission @ 10.30%. Is there any way, that we can deduct TDS as contractual payments @ 2%. Is there please explain the same.
