The fees per period, hours per period, and rate for excess hours will be in the client's contract and proposal. In this example, we are sending the invoice in the current month when the contract is starting, so the "next issue date" is the 3rd of the month. Because of this, there will be additional steps at the end of this SOP. Just make a mental note! If you are sending the invoice before the contract month begins, the "next issue date" would be the 1st of the month in which the contract begins (aka, in the future from when you are creating the invoice).
