I do security installation work involving a large number of pieces (cameras, detectors, poles, external subcontract work etc). At the start of a new project I would like to assign a job number (related to a customer). Then I would like to have all expenses and income for that project to have that job number on them. At the end of the project I would like to see everything associated with that project, my expenses, income and hence profit for that job. Also it is useful to look back to a single purchase and to be able to see what job I bought it for.
Is this already possible? Is this something others would find useful? Is it worth putting on a wish list? Is this the same as adding a reference that has been requested in another forum topic?
