Tds claim

Hello Friends.

One of my client has the following invoicing system:

1. Give the estimate of total contract

2. As the contract progresses make the invoice only for the work completed.

Now the person who has engaged my client, claims the estimate amount as expense in his or her books & accordingly books TDS. This TDS amount reflects in my clients 26AS. Can this TDS amount be claimed in return for several years- years in which we book the invoice amounts.
