Hi Paul, thanks for your reply! We are not necessarily billing each child project individually - but a fraction of each will be billed monthly and we wanted to keep track of that if they all add up to one total. We were told we don't necessarily need to use a sales order - so we may go in a different direction. The reason we want to keep record of each individual project cost is to track how much we make on certain projects and using that to forecast for future scopes
