Monaca in-app-updater query?

[lammie1971]

I am developing my first app with Monaca. I think if it comes to fruition I will purchase the Monaca in-app-updater.

Do I have to pay for this during the development stage or when I package and publish the final app.

As it seems a lot to fork out now without necessarily knowing that I will need it.

Thanks in advance.
