Take this with a grain of salt... Funds will (in most cases!) be instantly available in your Wise account upon card transaction approval. Most of the time, as soon as your customer executes the card payment, you'll see the funds appear right away in your available balance.
In some instances, however (here's the grain of salt), there can be a delay of up to 1 day if the cardholder is considered high risk due to, for example, suspicious card activity. We make sure we protect you and keep our payment solutions as safe as possible. Anything else would be unWise, right?
