This companion volume is available in the Job Costing, Applicants Booking and Events Manager volumes and also requires the Sales Ledger to be present.
Usually, most invoicing will be carried out remotely via the Sales Order Processing, Service Control, Job Costing or other volumes. However, there may be occasions when it is necessary to create an Invoice without first creating an Order (for example, if the Sales Order Processing Volume isn’t present). The InvoiceWriter is available for such occasions.
