Yes. You can always ask us to change NPA state to "active" state where we will start working on your project as per available schedule. You need to provide all inputs/approvals/payments as requested by designing team at the time of restarting of project.
Please note there may be demand of part payment of remaining amount to restart the project. This is only a formality to ensure client active involvement in the project this time & it is adjusted in your total billing amount.
Also your advance with us for any particular project is there for "NPA project" till 3 months. After that we remove project files from our system & your bill shall be settled for your advance adding tax ( if applicable) and project is closed.
NAP project may be started after completing current project in hand and will be put in queue for earliest development.
