Don't sweat it. SortScape has got your back. If the first charge doesn't work out, it'll automatically try to process the payment again, up to three times in total. Our payment provider uses some smart tech to figure out the best time to try again, which is usually within a day or two. Just make sure there's enough money in your account, and you should be good to go for the next charge attempt.
If the payment has already failed twice, please contact support to avoid your account being disabled.
