The funds in your Seller Dashboard move from "Pending" to "Available" as soon as the buyer has approved the sale or automatically 4 days after the item has arrived at the buyer's address-- whichever comes first.
Once the funds have been made "Available" in your Seller Dashboard, you can withdraw the funds by linking a bank account and clicking "Cash Out".
Cashing out is safe. TackTackRoom uses Stripe to process payments and bank transfers securely. You can read more about Stripe here. Stripe is certified to PCI Service Provider Level 1. This is the most stringent level of certification available.
