Flippa allows you to accept or decline a new bidder application. Once a bidder has been approved, they can continue to place bids on your listing.
You can reject a pending bid application if you have researched the bidder and would rather not sell to them. You won't be able to later accept this bidder, so it's worth taking a moment to properly research the bidder.
You have up to three days to accept a pending bid application. After three days, the application will be automatically rejected.
Early bids on your listing may come in under the reserve price. This is normal, and you will never be obligated to sell your site for less than the reserve price.
