Managing project supplies of items, services, and expenses is an integral and critical aspect of the execution of all jobs. You can use inventory on-hand or make job-specific purchases using purchase orders and/or purchase invoices. If the purchase process does not require that the physical transaction be recorded separately, then a purchase may be processed in a purchase invoice only or in a Job G/L journal. The Job G/L Journal is a general journal, which is integrated with the general ledger. It is designed for posting job transactions such as usage and expenses.
For example, a service job on a computer requires a new disk. You create a purchase invoice to buy a new disk and record the job it will be used on.
The following table describes a sequence of tasks, with links to the topics that describe them. These tasks are listed in the order in which they are generally performed.
