Can I use your plugins and upfront for my customer Websites?

I hope you having a good day.
I checked the TOS in your website, but I am not good at english in terms of legal document, which is difficult for non-native speaker some times.

So, I want to ask this here.

I am now creating and is going to sell a wordpress site for my client, and I want to utilize the power of WPMUDEV such as WP-Defender, upfront. Can I use your service for customer?

King regards
