The client has the possibility to reject your check-out proposal and submit a new one (the correct times), after which you can accept these and thus resolve the situation. The best way to fix this is to immediately contact the client as soon as you’ve realised that you’ve made a mistake. The invoices will only be produced and paid for after the check-out has been completed.
What if my check-out has already been completed?
At this moment we can no longer adjust the times for you. The best possible way to solve this is to compensate the forgotten hours with a future shift at the same client. Consult them about what they think is the best option for the both of you.
