Project Billing
If you enter a project code when you use Bill Job, all job sheet items for jobs that are in the project will be displayed (but not sub-jobs for these jobs). This allows you to bill a number of jobs (the debtor is the project client) in one go.
A side effect of this is that the invoice will be tagged to the project, and not to the individual jobs. Thus the income will not be recognised by the job report for the jobs (but will appear in the job report for the project).
