I am having difficulty understanding the subscription system

Hello, I am having difficulty understanding the subscription system. I subscribed to the professional version for two users for one year at $320.

Now, it says that $90 has been deducted for one month, which implies that each month would cost $90 or more.

I have not added any additional seats; I only assigned admin permissions to developers. Are there any additional charges for that?

You need to pay for each editor seat in team. What access developers have? Only view or they use dev mode?

Dev mode is a part of editor seat.

We are a team of freelancers working on multiple projects, which I need to hand over to different developers. Do I have to pay for each new developer on every new project? This doesn’t seem logical!

If the developer needs a dev mode, yes.

Well, dev mode is not a free option in Figma, you need to pay for everyone who use it in your team.

But developers can use a free alternative with view only access — properties panel. They can copy styles and export assets from it. Maybe that will be enough in some projects.
