We will only bill overtime that you have pre-approved. Generally, your crew member will reach out to you once you reach 80% of their monthly hours alloaction. For example, if you lease a crew member 40 hours per month, they will contact you once you reach 32 hours, and request approval to go beyond 40 hours. They will only proceed once approved and will otherwise pause work at 40 hours. The overtime will be billed during the first week of the following month.
