Paypal handles all Label Worx credit transactions and on rare occurrences, the part of the process that updates our system with confirmation of your payment can be delayed.
Although the credit buying process is usually instant, we ask that you wait 12 hours to see if your credits appear. They usually appear within this time frame.
If in the unlikely event that your credits do not update onto your account within 12 hours after purchase then please contact Label Worx support.
