It is best to close the period at the end of the day. This is because a number of processes are running at night that ensure that the period closure is fully completed, and the new period can start. These processes ensure that the posting date of the invoices that are present in ISP-Invoice, but have not yet been posted in the ERP, is automatically moved to the first day of the new posting period. In addition, a period report is created in which the invoices that were already registered in the old period but not yet posted in the ERP system are included. You can close the period in the ERP system the next morning.
