Hi BHW, I was just wondering about how other SEOs are invoicing their clients. 1. How do you invoice your clients? (e.g: every week, after every link building campaign is completed, etc) 2. What do you charge in your invoices? (e.g: hours spent on link building, total project fees, etc) Personally for me, 1. I send an invoice at the end of every month 2. Total project fees as agreed in the contract Cheers!
