If submitted hours are correct, you should aim to approve them as soon as they are submitted by the freelancer. On average most businesses accept the hours within five days however, there is no mandatory deadline.
We encourage businesses to accept hours in a timely manner, as it contributes to a good payment rating on your profile. Businesses with an efficient rating attract more reactions. Worked hours are only included on an invoice once they have been accepted. Therefore, late approval delays payment to the freelancer. If approval is taking longer than expected, freelancers are encouraged to contact you for an update. They are running their own business after all!
