How does invoicing work for customers

How does invoicing via Level.works work?

We pay our flex workers every week on Friday. Invoicing towards the clients is synchronized with the flexworkers' payments! Before we send an invoice to the client, the hours must be approved. This is done through weekly approval via the client portal, the deadline for approval is Wednesday 23:59. All hours approved before that can be included with Friday's payment. We then send an invoice of these approved hours to the client on Thursday or Friday!
