Quick answer: Yes, you can stop a Community Gift at any time. The money collected moves to your Throne Balance, minus the service fee.
Before you stop
It's worth thinking about how your community might feel if they contributed toward something they expected to be funded. Stopping a Community Gift without a heads up can affect the trust you've built with your fans. We'd recommend letting them know if your plans change.
How to stop a Community Gift
Open your Throne Wishlist.
Click the three dots in the top left corner on the Crowdfunded item.
Select "Abort Community Gift" and confirm.
Why you received less than what was raised
Crowdfunded payout items carry a one-time service fee of 9.75% on the goal. If you stop the Crowdfund early, that unpaid fee is deducted from the funds raised before the rest moves to your Throne Balance. That's why the amount you receive is lower than the total contributed.
