This is probably one of the most annoying moments of your day, we'll try and make sure it's not also one of the most confusing :)

You accidentally put in the wrong credentials

While moving fast, sometimes you can move a bit too fast! Double and triple-check that the billing information you put in is correct.

Your card limit has been reached

In this case, you have received a message with a link to your card.

Once you increase the limit of your card, you can retry your purchase.

Your business balance is insufficient

You'll need to reach out to your Float administrator to top-up your balance. Once you have enough money in your account, you can retry your purchase.

The transaction was declined by the merchant

If a transaction has been declined by the merchant, sometimes it won't show up in Float at all. Float Support may be able to offer additional insight but usually this must be taken up with the merchant directly. 

PIN try limit exceeded

If you have previously entered your PIN incorrectly too many times, your card can become locked, preventing new transactions going forward. See: Resetting a PIN on a Physical Card for steps to reset your PIN and unlock your card.

Address Verification Decline

Due to the nuance of AVS, please review the link above.
