We all make mistakes. If you have entered the hours incorrectly, contact the business asap. The business can decline the hours and amend what has been submitted. If the business has already approved the hours, there are two options:

Underpaid | If you have not been paid enough hours, the business can post a 'dummy' gig for you to match with and submit the additional hours. This is only possible if you have been underpaid at least three additional hours, as this is the minimum hours for a gig. 
If this isn't the best solution for you, please contact us

Overpaid | If you have been paid too much, you can contact YoungOnes. We will process the extra hours in the invoicing process.
