Use of single-site License/ Paid Plugin in Development and Production with different Domains

Hi,

We are a software development company and one of our clients purchased a single-site license/paid version of your plugin.

The domain for development server and Production server is different  for the client.

Can you  please confirm/guide us , how can we use the same keys/license for development environment with a different domain and then use the same license/keys on production with a different domain?

Kind Regards,
