AA-45- Expense Reimbursement Invoice to Client

All Respected Members,

please educate me on following:

Suppose, we have paid air ticket charges, accommodation and local traveling charges on behalf of our client which they asked us to claim with them, please tell me how we will generate invoice to claim these expenses and does taxation will be applicable on it. For example: sales tax will be charged on it or will income tax/ TDS be deducted from client on it ?

Thanks in advance for reply precious time and efforts to reply this query.
