Managing g-suite for a small company

Hi everybody,

I am a freelancer who manages/caters for a few small clients. I am in the process of building a new website for a (three person) company who also likes my hosting package. They told it would be nice if I could also manage their G-suite account, since they now use a third party for that.

But I don't like the idea of managing their g-suite because:
1. I think they can do it themselves, they probably met a salesperson who says the opposite.
2. It's not what interest me, so i might end up doing a bad job.

I do like the idea of managing their g-suite because:
1. It sounds like free money.

Am i seeing things wrong or am i missing something? Is it hard to manage a g-suite account for a (small) company? You guys have any experience with this?

Thanks a bunch
