What do I get for inviting someone?
More storage on Free when they share a link with a client, and a month of credit when they pay.
Settings → Plan and usage has your own invite link. Anybody who signs up through it is counted against it for 60 days.
The reward follows what they do, never the signup itself.
When they share a review link with a client, and you are on Free, your storage goes up by 5 GB, up to 20 GB in total. Sharing is the bar because somebody who has a client is somebody the product is for.
When they pay for a plan, and you are paying through Stripe, you get one month of your own plan as credit on your account. It appears on your next invoice.
There is no reward for a signup on its own, and none for inviting yourself. Storage earned this way stays as long as the account does.
