There is no mistake with the invoice. If you don’t want to be charged for a droplet you need to destroy it.

From https://www.digitalocean.com/pricing/

“Am I charged while my Droplet is in a powered-off state?

Yes. Your diskspace, CPU, RAM, and IP address are all reserved while your Droplet is powered off. If you want to save a Droplet for future use take a snapshot of it and then destroy it. You’ll be able to create a new Droplet from the snapshot image anytime to bring it back online.”

I think this is not an ethical practice. Why I pay money when droplet is off ? What does hourly plan do ?

Hours droplets sell a commercial deception? Because it does not work, do not pay, is the logic of taking hours.

Well, let’s assume it is. Why not charged past months ? Why charged now ? The first time charged this month.

You are charged for every hour that your droplet exists, because this means that you have resources (memory, disk, IP address) reserved for you.

There’s nothing unethical about it - you’ll find that nearly every single VPS provider on the planet is the same way.

There is no deception. The resources for that droplet are being reserved for you whether it’s on or off and that’s what you’re paying hourly for. The ability to use those resources when you want.

If you weren’t charged in the past it’s because 1) the droplet didn’t exist or 2) you had credit on the account to cover the charge.

I’m using DigitalOcean since 2 days, because they offer the option to only pay for the time you actually using your droplet (whether it is on or off, which is cleary stated in the documentation). (Do you also stop paying for your car insurance when the car is tunred off???)

When I’m done using my droplet, I power it off, create a snapshot and then I destroy my droplet. That shouldn’t be a surprise for people that can read.
